NOTE Notes is used to indicate supplementary information other than Warnings and Cautions. Read this manual carefully, and store it in a safe place. s-2

5 B-63404EN/03 SAFETY PRECAUTIONS 2 GENERAL WARNINGS AND CAUTIONS WARNING 1 Before operating the machine, thoroughly check the entered data. Operating the machine with incorrectly specified data may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. 2 Never attempt to machine a workpiece without first checking the programmed value, compensation value, current position, and external signal settings. Also, never attempt to machine a workpiece without first checking the operation of the machine. Before starting a production run, ensure that the machine is operating correctly by performing a trial run using, for example, the single block, feedrate override, or machine lock function, or by operating the machine with neither a tool nor workpiece mounted. Failure to confirm the correct operation of the machine may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. 3 Ensure that the specified feedrate is appropriate for the intended operation. Generally, for each machine, there is a maximum allowable feedrate. The appropriate feedrate varies with the intended operation. Refer to the manual provided with the machine to determine the maximum allowable feedrate. If a machine is run at other than the correct speed, it may behave unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. 4 When using a tool compensation function, thoroughly check the direction and amount of compensation. Operating the machine with incorrectly specified data may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. FANUC CNC Controls s-3

6 SAFETY PRECAUTION B-63404EN/03 WARNING 5 The parameters for the CNC and PMC are factoryset. Usually, there is no need to change them. When, however, there is no alternative other than to change a parameter, ensure that you fully Failure to set a parameter correctly may result in the machine behaving unexpectedly, possibly causing damage to the workpiece and/or machine itself, or injury to the user. CAUTION 1 Immediately after switching on the power, do not touch any of the keys on the MDI panel until the position display or alarm screen appears on the CNC unit. Some of the keys on the MDI panel are dedicated to maintenance or other special operations. Pressing any of these keys may place the CNC unit in other than its normal state. Starting the machine in this state may cause it to behave unexpectedly. 2 The operator's manual for DeviceNet board describes all the basic functions of the CNC, including the optional functions. The selected optional functions vary with the machine. Some functions described in this manual may not, therefore, be supported by your machine. Check the machine specifications before using DeviceNet board. 3 Some machine operations and screen functions are implemented by the machine tool builder. For an explanation of their usage and related notes, refer to the manual provided by the machine tool builder. For example: On some machines, executing a tool function causes the tool change unit to operate. When executing a tool function on such a machine, stand well clear of the tool change unit. Otherwise, there is a danger of injury to the operator. Many auxiliary functions trigger physical operations, such as rotation of the spindle. Before attempting to use an auxiliary function, therefore, ensure that you are fully aware of the operation to be triggered by that function. s-4

7 B-63404EN/03 SAFETY PRECAUTIONS NOTE Command programs, parameters, and variables are stored in nonvolatile memory in the CNC. Generally, the contents of memory are not lost by a power on/off operation. However, the contents of memory may be erased by mistake, or important data in nonvolatile memory may have to be erased upon recovering from a failure. To enable the restoration of data as soon as possible if such a situation arises, always make a backup of the data in advance. FANUC CNC Controls s-5

18 1.DeviceNet FUNCTIONS OPERATION B-63404EN/ OUTLINE Unusable Network Functions DeviceNet functions cannot be used together with Profibus functions. Number of networks connectable to NC LCD-mounted type Series 16i/18i/21i One DeviceNet communications board can be mounted. The connection to the network is made by one function, either the slave function or master function. Stand-Alone type Series 16i/18i/21i Series 15 i -A, and Power Mate i-d/h series Two DeviceNet communications boards can be mounted. Note, however, that when two boards are mounted, one should be used as the slave function and the other should be used as the master function. Outline of DeviceNet function specifications (1) Master functions Poll I/O Connection is supported. Max. number of connected slaves: 32 (MAC-ID setup range: 0 to 63) Slave assigned addresses The respective DI/DO signals are assigned continuously starting from any address in the R area, with single bytes (8 bits) assigned to each address. Number of slave DI/DO communication points : Input signal 0 to 32 bytes : Output signal 0 to 32 bytes (2) Slave function MAC-ID setup range: 0 to 63 Assigned addresses DI/DO signals are assigned continuously starting from any address in the R area, with single bytes (8 bits) assigned to each address. Number of DI/DO communication points : Input signal 0 to 64 bytes : Output signal 0 to 64 bytes

19 B-63404EN/03 OPERATION 1.DeviceNet FUNCTIONS 1.2 SETTING MASTER FUNCTIONS To use the DeviceNet master functions, you must set the bus parameters and the slave parameters. "Bus parameters" are for identifying on the network the DeviceNet interface board that is currently mounted on the control unit (CNC). "Slave parameters" are for identifying on the network each of the connected slaves. The bus parameters are used to specify an MAC-ID, baud rate, address assignment information, and information about whether to hold or clear a DI signal related to a communication error(*). Setting the slave parameters involves setting the MAC-ID, vendor ID, device type, product code, connection and DI/DO address assignments of the node to be connected to each slave No. The following briefly describes each of these items. The "MAC-ID (Media Access Control ID)" is the ID used for identifying on the network the DeviceNet communications board that is currently mounted on the CNC. This MAC-ID is set to a value within the range 0 to 63, and must not duplicate the ID of another node on the network. The "baud rate" is the network's communicating speed, and must be set to the same value for each node to be connected to the network. "Address assignment" refers to setting of the DI/DO sizes when I/O of the DI/DO signals is performed and to setting of the PMC addresses (addresses of R areas) that are used. "Vendor ID, device type and product code" are used for specifying the type of each slave that is connected to the network. If these setting values do not match the values specific to each of the actually connected slaves, a connections error will occur. "Connection" refers to the connection type with each slave. Normally, set "0". Setting to "0" sets support of Poll I/O Connection. * See Chapter 2, "Configuring a Safe System" for information about whether to hold or clear a DI signal related to a communication error.

Table (b) describes this diagnostics information. Setting the MAC-ID and baud rate Set the node number "2. MAC-ID" of this master node and the baud rate "3. BAUD RATE" to appropriate values referring to items 2 and 3 in Table (a). Assigning status information Set to parameters the addresses and sizes of the R areas to which status information data is to be assigned. The content up to the STATUS SIZE setting value items (see Table (c)) is assigned continuously starting from the specified R area signal. For example, to assign eight bytes of status information from R1500 onwards, set each of the data items as follows in screen STATUS ADDRESS = R STATUS SIZE = 8 Status information is assigned to R area signals as follows according to this setting. Status Information Assignments R1500 STATUS information R1501 Slave communications status 1 R1502 Slave communications status 2 R1503 Slave communications status 3 R1504 Slave communications status 4 R1505 IDLE/ACTIVE information R1506 CAN BUS STATUS 1 information R1507 CAN BUS STATUS 2 information On the PMC, start communications with the slaves using this status information (STATUS information, slave communication status, etc.). Also use this status information to process on the PMC any communications errors that may occur. The error status of this status information is returned to the normal communications status when the cause of the error is removed. So, if the error status must be held, perform this operation on the PMC. CAUTION When you set the assignment data, carefully set the data so that areas to be secured as data do not duplicate areas that are currently used for ladder programs on the PMC. FANUC CNC Controls

45 B-63404EN/03 OPERATION 1.DeviceNet FUNCTIONS Master Function Data Refresh Rate The "data refresh rate" is the time required for the control unit (CNC) to update all I/O signals assigned to the R areas. CAUTION The data refresh rate does not indicate the I/O response time on the network. The I/O response time is dependent on the condition of the network. Refreshing of I/O signals in the master function is performed every 8 msec at a maximum of 32 bytes for both DI and DO. In other words, the data refresh rate changes as shown in the following table according to the number of communications points on each slave. Table (a) Total Number of Slave Communications Points Data Refresh Rate 1 to 32byte 8ms 33 to 64byte 16ms 65 to 96byte 24ms In the same way from here on, the data refresh rate is extended by 8 ms at a time as the total number of slave communications points increases by 32 bytes. For example, the total DI size becomes 68 bytes when the sizes of the DI/DO signals on each slave are set as follows. (See table below.) Table (b) Slave No. DI Size DO Size Total DI/DO size At this time, as the data refresh rate of the DI signal is 24 msec and the total DO size is 32 bytes according to Table (a), the data refresh rate of DO signals becomes 8 msecs. In this instance, the time until all DI/DO signals are updated becomes the slower time of 24 msec. FANUC CNC Controls

69 B-63404EN/03 OPERATION 1.DeviceNet FUNCTIONS Slave Function Data Refresh Rate The "data refresh rate" is the time required for the control unit (CNC) to update all I/O signals assigned to the R areas. NOTE The data refresh rate does not indicate the I/O response time on the network. The I/O response time is dependent on the condition of the network. Table 1.3.2(a) shows the relationship between the total number of DI/DO communications points and the data refresh rate in the slave function. Table (a) Total Number of Slave Communications Points Data Refresh Rate 1 to 64byte 8ms The relationship changes as follows when master functions are used together with slave functions. Table (b) Number of DI/DO Communications Points (byte) Data Refresh Rate 1 to 32 8ms 33 to 64 16ms * A maximum of 32 bytes of DI/DO is updated every 8 msec.

74 2.CONFIGURING A SAFE SYSTEM OPERATION B-63404EN/03 2 CONFIGURING A SAFE SYSTEM This chapter describes how to configure a safe system when creating a system using DeviceNet functions

75 B-63404EN/03 OPERATION 2.CONFIGURING A SAFE SYSTEM 2.1 TROUBLESHOOTING COMMUNICATIONS ERRORS Using the Series 16i/18i/21i-A/B (DeviceNet function software series 6576/edition 02 or earlier) With this DeviceNet function, assignment data is not updated when a communications error occurs. For this reason, DI data is held at the state that was active when the alarm was detected. Using the Series 16i/18i/21i-A/B (DeviceNet function software series 6576/edition 03 or later) or Series 15i-A In this DeviceNet function, whether to hold or clear the DI data when a communication error has occurred can be selected by setting the DI HOLD/CLEAR parameter as follows: DI HOLD/CLEAR 0: The DI data is held in the state where it was when an alarm condition was detected. 1: The DI data is cleared. When designing the system, design the system so that the status of the status information is monitored at all times and the system operates stably. You can also prepare signals in DI/DO data, by which data is exchanged, for indicating whether or not communications is being performed instead of using the status information, and you can also judge whether or not communications is being performed normally by monitoring whether or not chose signals are being read. On the slave system side, start and continue operations after receiving permission from the master device. FANUC CNC Controls

76 2.CONFIGURING A SAFE SYSTEM OPERATION B-63404EN/ HANDLING MULTIPLE-BYTE DATA With this DeviceNet function, data communications on the network and updating of data assigned to PMC R area are performed asynchronously. For this reason, handling of data of two bytes or longer must be synchronized on the PMC (in the ladder program). For example, when multiple-byte DI data is read from the master device on a slave, signals for acquiring synchronization must be provided before and after the data, DI data must be read when the synchronizing signals set by the master device is correctly read by the slave, and the slave must reset the synchronizing signals when it has finished reading the DI data and then notify the master device that it has finished reading the DI data

80 B-63404EN/03 CONNECTION 1.CONNECTING DeviceNet FUNCTIONS 1.2 DeviceNet CABLES There are two types of DeviceNet cable: thick cable and thin cable. Normally, thick cable is used as the trunk line when a long-distance network is required. Normally, thin cable is used as branch cable as it is thinner and more flexible than thick cable. Thin cable can also used as the trunk in short-distance networks. Use cables that comply with the DeviceNet standard

81 1.CONNECTING DeviceNet FUNCTIONS CONNECTION B-63404EN/ CABLE LENGTH AND BAUD RATE There are some restrictions in configuring a network: maximum network length, branch length and total branch length. These factors are also restricted by the baud rate. Maximum network length The "maximum network length" refers to whichever is longer, the distance between furthermost nodes or the distance between terminators. Whichever of these is longer is the maximum network length. Terminator Terminator T-branch tap Node Node Branch length T-branch tap Branch length Node Communications power supply Node The following table shows the maximum network length according to cable type. Cable Type Thick cable (5-wire) Thin cable (5-wire) Maximum Network Length 500m 100m NOTE Thin cable can also be used as the trunk if the maximum network length is within 100 m. In this case, also pay attention to the maximum current capacity of the cable so that this limit value is not exceeded. The maximum network length is also limited by the baud rate. Baud Rate Maximum Network Length When Only Thick Cable Is Used Maximum Network Length When Only Thin Cable Is Used 500 K bit/sec 100m 250 K bit/sec 250m 100m 125 K bit/sec 500m FANUC CNC Controls

82 B-63404EN/03 CONNECTION 1.CONNECTING DeviceNet FUNCTIONS NOTE When Thick Cable Is Used Together With Thin Cable A mixture of thick cable and thin cable can be used for the cable connecting furthermost nodes. Note, however, that in this case, the line lengths of each type of cable must satisfy the expression in the following table. So, the total network length becomes shorter than when the network is configured by connecting only thick cable. Prevent the maximum current consumption of the cables from being exceeded. Baud Rate Maximum Network Length 500 K bit/sec Lthick + Lthin < 100m 250 K bit/sec Lthick Lthin < 250m 125 K bit/sec Lthick + 5 Lthin < 500m Lthick: Length of thick cable, Lthin: Length of thin cable Example Maximum network length Terminator 1m 100m 25m 40m 1m Terminator T-branch tap Node T-branch tap 3m 2m Branch length Node Node 5m Communications power supply Node Baud Rate Maximum Network Length Acceptability 500 K bit/sec Lthick + Lthin=175 < 100m NG 250 K bit/sec Lthick Lthin = =250 < 250m OK 125 K bit/sec Lthick + 5 Lthin = = 375 < 500m OK According to the above calculation, communications at 250 kbit/sec and 125 kbit/sec is possible in this case. Note, however, that a network cannot be configured if the maximum allowable current consumption of the cables is exceeded even if the above conditions are satisfied

83 1.CONNECTING DeviceNet FUNCTIONS CONNECTION B-63404EN/03 Branch length The "branch length" refers to the longest value from where the trunk is divided into a branch up to the first node connected to the branch. The maximum branch length is 6 m. Branches can be sub-divided into further branches. Trunk line Calculation example Trunk line T-branch tap Branch length (max. 6 m) Node 2m Node A 1m Branch length T-branch tap A 4m T-branch tap B 1m Node B Node C T-branch tap A to node A: 6 m T-branch tap A to node B: 5 m T-branch tap A to node C: 6 m All branches are within 6 m. Total branch length The "total branch length" refers to the length obtained by totaling the length of all branches. The total branch length is sometimes exceeds this restriction even if all of the branches is within 6 m. Also, the total branch length restriction also varies according to the baud rate. Baud Rate Maximum Total Branch Length 500 K bit/sec 39m 250 K bit/sec 78m 125 K bit/sec 156m Calculation example Terminator 2m Node A 1m T-branch tap A 4m T-branch tap B 1m Node B Node C 6m Node D Terminator T-branch tap C T-branch tap A to T-branch tap B: 4 m T-branch tap B to Node A: 2 m T-branch tap B to Node B: 1 m Node B to Node C: 1 m T-branch tap C to Node D: 6 m The total branch length is 12 m.

Drain wire/shield Signal line (CAN_L) Signal line (CAN_H) Power line (V-) Power line (V+) Grounding the network In the DeviceNet specification, it is recommended that only one place on the network be grounded and a place as near as possible to the center of the network be grounded to prevent a ground loop. As shown in the figure above, connect the shielded lead of the cable to frame ground (FG) for the communications power supply and ground FG to a maximum resistance of 100. When multiple power supplies are used, connect and ground the shielded lead only at the power supply near the center of the network. Do not connect the shielded lead to the frame ground of other power supplies, and ground these FGs to a maximum of 100. When you use multiple power supplies, user a special power supply tap made by other manufacturers.

Use a power supply that satisfies the specifications shown in the table below and that has insulated AC input and DC output as the communications power supply.

The maximum current capacity of the communications cable is 8A on thick cables and 3A on thin cables. The communications power supply is connected in various forms depending on the user's power supply requirements. The current capacity of the branch varies according to the branch length. The longer the branch, the smaller the branch's maximum current capacity becomes. The same applies if the cable used as the branch is thick cable or thin cable. Calculate the possible current capacity (I) on a single branch (the total current that is consumed on each branch) according to the following expression: I = 4.57/L I: Allowable current (A) L: Branch length (m) FANUC CNC Controls

92 B-63404EN/03 CONNECTION 1.CONNECTING DeviceNet FUNCTIONS Designing a Power Supply Connection Design the power supply connection in the following order: (1) Provisional determine the position of the power supply. (2) Calculate the current consumption of all nodes to be located on the network. (3) Calculate the length at the provisional position, and calculate a rough value for the current that can be supplied to the cable according to the graph. (4) Verify whether or not the supplied current satisfies the current consumption. (5) Change the position of the power supply and verify again. (6) If the conditions are not satisfied by the simple calculation according to the graph in step (3), calculate the supplied current according to the calculation expression and verify again. (7) If the conditions in the calculation expression are not satisfied in step (6), provide two or more power supplies, separate the power supply paths, and verify whether or not the supply current satisfies the conditions for each of the power supplies Determining the Power Supply Locations Power supplies can be located in the four configurations shown below. In principle, select configurations (1) and (2). If the power supply conditions are not satisfied in configurations (1) and (2), study the use of configuration (3). To provide two or more power supplies for the simultaneous supply of power, configuration (4) is also possible. (1) When nodes are located both sides of the power supply: Terminator Power supply tap or T-branch tap Terminator Node Node Node Node Node Communications power supply (2) When the nodes are located to one side of the power supply: NOTE We recommend the configuration in (1) when supplying power to many nodes from a single power supply

So, use two or more power supplies. When thick cable is used in the configuration in (1), there will be no problems if the current capacities on both sides of the trunk from the communications power supply are both 8A or less. For this reason, a configuration up to a maximum current capacity of 16A is possible. If the current capacity flowing to the thin cable exceeds 3A when thin cable is used for the trunk, verify whether or not the conditions are satisfied by changing to thick cable. FANUC CNC Controls

94 B-63404EN/03 CONNECTION 1.CONNECTING DeviceNet FUNCTIONS Factors for determining the power supply locations Two factors for determining whether or not current can be supplied normally are the current capacity required by each node and voltage drop on the cable. Calculate the following two values beforehand: Current capacity required at each node Distance from the power supply(ies) How to calculate the power supply There are two ways of calculating the power supply for the trunk: 1) Simple calculation according to the graph 2) Calculation by calculation expression (Voltage drop is calculated from the resistance of the communications cable and the current consumption.) NOTE Calculate the power supply so that the conditional expression for the current consumption on branches according to the branch length is satisfied for each branch. Distance to furthest node on trunk or to branch tap from power supply Regarded as no distance Terminator Power supply tap Node Node Node Node Terminator Communications power supply The conditions are sometimes satisfied by calculating using the calculation expression even if the power supply conditions are not satisfied by calculating simply according to the graph. In this case, locating the power supply at a hypothetical position poses no problem. NOTE When using a common power supply for communications and the NC, the power supply cannot be calculated by graph-based simple calculation in the following item. Calculate the power supply according to the calculation expression

95 1.CONNECTING DeviceNet FUNCTIONS CONNECTION B-63404EN/ Verification by Graph-Based Simple Calculation Voltage drop occurs when current flows to the communications cable. The longer the communications cable, the larger the current value becomes and the larger the voltage drop occurs. The voltage of the communications power supply at each node must be 11 VDC or more.

96 B-63404EN/03 CONNECTION 1.CONNECTING DeviceNet FUNCTIONS Graph-based simple calculation The items must be checked in order (1) to (3) for each of the nodes located in the same direction viewed from the power supply. If nodes are located on both sides of the power supply, items (1) to (3) must be checked in each direction. (1) Calculate total current consumption (A) for all nodes located on the network in each direction. (2) Calculate from the graph maximum current (B) that can flow to the cable based upon the cable type (thick or thin) and the distance to the furthermost end on the trunk from the power supply. (3) If total current consumption (A) calculated in (1) is less than or equal to maximum current (B) calculated in (2), this means that the power supply conditions are satisfied for all nodes. NOTE The graph to refer to varies according to the cable type (thick or thin) used for the trunk. Remedies If total current consumption (A) calculated in (1) is greater than maximum current (B) calculated in (2), study the following: Move the power supply towards the center to configure the network so that nodes are located on both sides of the power supply. If nodes are already located on both sides of the power supply, move the power supply towards the direction on which the larger current consumption is required. Swap with thick cable if thin cable is used. If A is grater than B in any of the above measures, study the positions of the nodes according to the calculation expression taking into the actual positions of the nodes. When the power supply unit is located at the one of the network (example 1): The following shows an example where thick cable having a total length of 200 m is used for the power supply, and the communications power supply is located at the end of the network. In this example, the current consumptions of each node are assumed to be as shown in the following figure. 200m Terminator Power supply tap Node 0.1A Node 0.25A Node 0.05A Node Terminator 0.25A Trunk line (5-lead cable) Communications power supply Total length of power supply line = 200 m

97 1.CONNECTING DeviceNet FUNCTIONS CONNECTION B-63404EN/03 Total current consumption = 0.1A A A A = 0.65A Maximum possible current calculated from the table for thick cable = 1.53A The relationship becomes "total current consumption is less than the maximum current," so you can verify that power can be supplied to all nodes. When the power supply unit is located at the center (example 2): The following shows an example where thick cable having a total length of 240 m is used for the power supply, and the communications power supply is located at the center of the network. As the communications power supply is located in the center of the network, the maximum current flows to both the left and right of the power supply. For this reason, a current twice the maximum current can be supplied compared with when the communications power supply is located at the end of the network. In this example, the current consumptions of each node are assumed to be as shown in the following figure. 120m Power supply tap 120m Terminator Node 0.1A Node 0.45A Within 3 m Node 0.25A Node Terminator 0.3A Trunk line (5-lead cable) Communications power supply Total length of power supply line (left side) = Total length of power supply line (right side) = 120 m Total current consumption (left side) = 0.1 A A = 0.55 A Total current consumption (right side) = 0.25 A + 0.3A = 0.55 A Maximum current (left side) calculated from the table for thick cable = Approx. 2.5 A Maximum current (right side) calculated from the table for thick cable = Approx. 2.5 A (The above values are calculated by linear approximation between 100 and 150 m.) The relationship becomes "total current consumption (left side) is less than the maximum current (left side)" and the "total current consumption (right side) is greater than the maximum current (right side)," so you can verify that power can be supplied to all nodes. FANUC CNC Controls

98 B-63404EN/03 CONNECTION 1.CONNECTING DeviceNet FUNCTIONS When current consumption is uneven on either side of the power supply unit (example 3) The following shows an example where thick cable having a total length of 240 m is used for the power supply, and the communications power supply is located by moving it slightly away from the center of the network. If the total current consumption is uneven on either side of the power supply unit and is insufficient even if the communications power supply is located in the center of the network, the current consumption conditions are sometimes satisfied by moving the power supply unit slightly. In this example, the current consumptions of each node are assumed to be as shown in the following figure. When the power supply unit is located in the center: 120m Power supply tap 120m Terminator Node 1.1A Node 1.25A Node 0.5A Within 3 m Node 0.25A Node Node Terminator 0.25A 0.85A Trunk line (5-lead cable) Communications power supply Total length of power supply line (left side) = Total length of power supply line (right side) = 120 m Total current consumption (left side) = 1.1A A + 0.5A = 2.85A Total current consumption (right side) = 0.25A+0.25A+0.85A=1.35A Maximum current (left side) calculated from the table for thick cable = Approx. 2.5 A Maximum current (right side) calculated from the table for thick cable = Approx. 2.5 A (The above values are calculated by linear approximation between 100 and 150 m.) The relationship becomes "total current consumption (left side) is greater than the maximum current (left side)," so it can be seen that the current consumption is insufficient on the left side. To remedy this, move the position of the power supply unit to the left as shown in the figure below. 100m Power supply tap 120m Terminator Node 1.1A Node 1.25A Within 3 m Communications power supply Node 0.5A Node 0.25A Node Total length of power supply line (left side) = 100 m Total length of power supply line (right side) = 140 m Node Terminator 0.25A 0.85A Trunk line (5-lead cable)

As a result, the relationship becomes "total current consumption is greater than the maximum current" for both the left and right sides, so you can verify that power can be supplied to all nodes.

100 B-63404EN/03 CONNECTION 1.CONNECTING DeviceNet FUNCTIONS Verifying by Calculation Expression If the conditions cannot be satisfied by simply calculating from the graph, verify the conditions according to the actual positions of each node and the communications power supply. With DeviceNet, the maximum voltage drop allowed in a system is stipulated as 5V for each of the power supply lines (V+, V-) based upon the voltage specifications (24 VDC) of the communications power supply and the input voltage specifications (11 to 25 VDC) of the communications power supply for each device. This 5 V voltage drop comprises an allowable voltage drop of 4.65A on the trunk and an allowable voltage drop of 0.35V on the branches. The approach for considering voltage drop in the cable is as follows. In the DeviceNet standard, the voltage drop in the communications cable is stipulated to within 5 V or less including margin taking into consideration the voltage specifications (24 VDC) and the input voltage specifications (11 to 25 VDC) of the communications power supply of each device. V1 Voltage drop at V+ (VA) Voltage drop at V- (VB) V1: Supply voltage of communications power supply. Set V1 to 23 V taking into consideration the fluctuation range of the power supply voltage. V2: Supply voltage to each node. Set V2 to > 13 V taking the margin into consideration. VA: Voltage drop at power cable V+ VB: Voltage drop at power cable V- On DeviceNet, set VA to less than or equal to 5V and VB to less than or equal to 5V. The voltage drop on the communications cables is stipulated at 5V or less on each of the power lines (V+, V-). This 5 V voltage drop comprises an allowable voltage drop of 4.65A on the trunk and an allowable voltage drop of 0.35V on the branches. V2 Supply voltage of communications power supply Supply voltage to each node Calculation expression Fist, investigate the distance between the power supply and each of the nodes, and the current consumption of the communications unit on each device. Then check whether or not the following conditional expression is satisfied. If the conditional expression is satisfied, the conditions for power supply to each node are satisfied. However, prevent the maximum current capacity (thick cable: 8A, thin cable: 3A) of the cables from being exceeded

101 1.CONNECTING DeviceNet FUNCTIONS CONNECTION B-63404EN/03 These conditions cannot be used if one power supply is shared as the communications power supply and the NC power supply.

How to separate power supply paths As two or more power supplies are used, use power supply taps for each of the power supplies. Power supply taps are not provided by FANUC.

104 B-63404EN/03 CONNECTION 1.CONNECTING DeviceNet FUNCTIONS Relationship with NC Power Supply In principle, the communications power supply cannot be shared as the NC power supply. Prepare separate power supplies for the communications power supply and for the NC power supply. However, note the following points when a power supply must unavoidable be shared due to the difficulty of providing separate power supplies because of space and cost considerations. The minimum stipulated input voltage of the NC power supply (24 VDC input type) is 21.6 V and is higher than that of the communications power supply. Satisfy this stipulation taking into consideration loss caused by voltage drop on the cables. Also, the NC control unit turns OFF when the communications cable breaks or is disconnected or when there is a short-circuit caused by shared use. Turn the communications power supply and NC power supply ON and OFF in the following sequence when separate power supplies are provided: Turn ON the communications power supply at the same time or before turning ON the NC power supply. Turn OFF the communications power supply at the same time or after turning OFF the NC power supply on the master node. If only the communications power supply is turned OFF during network operations, an abnormality may occur on other nodes that are currently communicating
