26 hapter : Getting Started 0 Power udgeting The L0 has four option card slots. To determine whether the combination of cards you select will have sufficient power, you will need to perform a power budget calculation. Power supplied Power is supplied from two sources, the internal base unit power supply and, if required, an external supply (customer furnished). The 0-0xx ( powered) PLs supply a limited amount of V power. The V output can be used to power external devices. For power budgeting, start by considering the power supplied by the base unit. ll L0 PLs supply the same amount of V power. Only the units offer V auxiliary power. e aware of the trade-off between V power and V power. The amount of V power available depends on the amount of V power being used, and the amount of V power available depends on the amount of V power consumed. etermine the amount of internally supplied power from the table on the following page. Power required by base unit ecause of the different I/O configurations available in the L0 family, the power consumed by the base unit itself varies from model to model. Subtract the amount of power required by the base unit from the amount of power supplied by the base unit. e sure to subtract V and V amounts. Power required by option cards Next, subtract the amount of power required by the option cards you are planning to use. gain, remember to subtract both V and V. If your power budget analysis shows surplus power available, you should have a workable configuration. L0/0 Option Modules User Manual; th Ed., /0

The protection provided by the equipment may be impaired if this equipment is used in a manner not specified in this manual. listing of our international affiliates is available on our Web site: WRNING: Providing a safe operating environment for personnel and equipment is your responsibility and should be your primary goal during system planning and installation. utomation systems can fail and may result in situations that can cause serious injury to personnel or damage to equipment. o not rely on the automation system alone to provide a safe operating environment. You should use external electromechanical devices, such as relays or limit switches, that are independent of the PL application to provide protection for any part of the system that may cause personal injury or damage. Every automation application is different, so there may be special requirements for your particular application. Make sure you follow all national, state, and local government requirements for the proper installation and use of your equipment. Plan for Safety The best way to provide a safe operating environment is to make personnel and equipment safety part of the planning process. You should examine every aspect of the system to determine which areas are critical to operator or machine safety. If you are not familiar with PL system installation practices, or your company does not have established installation guidelines, you should obtain additional information from the following sources. NEM The National Electrical Manufacturers ssociation, located in Washington,.. publishes many different documents that discuss standards for industrial control systems. You can order these publications directly from NEM. Some of these include: IS, General Standards for Industrial ontrol and Systems IS, Industrial Systems IS, Enclosures for Industrial ontrol Systems NE The National Electrical ode provides regulations concerning the installation and use of various types of electrical equipment. opies of the NE Handbook can often be obtained from your local electrical equipment distributor or your local library.

Emergency stop switch for disconnecting system power Mechanical disconnect for output module power Orderly system shutdown sequence in the PL control program Emergency Stops It is recommended that emergency stop circuits be incorporated into the system for every machine controlled by a PL. For maximum safety in a PL system, these circuits must not be wired into the controller, but should be hardwired external to the PL. The emergency stop switches should be easily accessed by the operator and are generally wired into a master control relay (MR) or a safety control relay (SR) that will remove power from the PL I/O system in an emergency. MRs and SRs provide a convenient means for removing power from the I/O system during an emergency situation. y de-energizing an MR (or SR) coil, power to the input (optional) and output devices is removed. This event occurs when any emergency stop switch opens. However, the PL continues to receive power and operate even though all its inputs and outputs are disabled. The MR circuit could be extended by placing a PL fault relay (closed during normal PL operation) in series with any other emergency stop conditions. This would cause the MR circuit to drop the PL I/O power in case of a PL failure (memory error, I/O communications error, etc.).

31 hapter : iscrete I/O Guidelines 0 Emergency Power isconnect properly rated emergency power disconnect should be used to power the PL controlled system as a means of removing the power from the entire control system. It may be necessary to install a capacitor across the disconnect to protect against a condition known as outrush. This condition occurs when the output Triacs are turned off by powering off the disconnect, thus causing the energy stored in the inductive loads to seek the shortest distance to ground, which is often through the Triacs. fter an emergency shutdown or any other type of power interruption, there may be requirements that must be met before the PL control program can be restarted. For example, there may be specific register values that must be established (or maintained from the state prior to the shutdown) before operations can resume. In this case, you may want to use retentive memory locations, or include constants in the control program to insure a known starting point. Orderly System Shutdown Ideally, the first level of fault detection is the PL control program, which can identify machine problems. ertain shutdown sequences should be performed. The types of problems are usually things such as jammed parts, etc. that do not pose a risk of personal injury or equipment damage.

32 hapter : iscrete I/O Guidelines System Wiring Strategies The irectlogi Micro PLs are very flexible and will work in many different wiring configurations. y studying this section before actual installation, you can probably find the best wiring strategy for your application. This will help to lower system cost, wiring errors, and avoid safety problems. PL Isolation oundaries PL circuitry is divided into three main regions separated by isolation boundaries, shown in the drawing below. Electrical isolation provides safety, so that a fault in one area does not damage another. powerline filter will provide isolation between the power source and the power supply. transformer in the power supply provides magnetic isolation between the primary and secondary sides. Opto-couplers provide optical isolation in Input and Output circuits. This isolates logic circuitry from the field side, where factory machinery connects. Note that the discrete inputs are isolated from the discrete outputs, because each is isolated from the logic side. Isolation boundaries protect the operator interface (and the operator) from power input faults or field wiring faults. When wiring a PL, it is extremely important to avoid making external connections that connect logic side circuits to any other.

34 hapter : iscrete I/O Guidelines Sinking/Sourcing oncepts efore going further in our study of wiring strategies, we must have a solid understanding of sinking and sourcing concepts. Use of these terms occurs frequently in input or output circuit discussions. It is the goal of this section to make these concepts easy to understand, further ensuring your success in installation. First we give the following short definitions, followed by practical applications. Sinking = Path to supply ground ( ) Sourcing = Path to supply source (+) First you will notice that these are only associated with circuits and not, because of the reference to (+) and ( ) polarities. Therefore, sinking and sourcing terminology only applies to input and output circuits. Input and output points that are either sinking or sourcing can conduct current in only one direction. This means it is possible to connect the external supply and field device to the I/O point with current trying to flow in the wrong direction, and the circuit will not operate. However, we can successfully connect the supply and field device every time by understanding sourcing and sinking. For example, the figure to the right depicts a sinking input. To properly connect the external supply, we just have to connect it so the the input provides a path to ground ( ). So, we start at the PL input terminal, follow through the input sensing circuit, exit at the common terminal, and connect the supply ( ) to the common terminal. y adding the switch, between the supply (+) and the input, we have completed the circuit. urrent flows in the direction of the arrow when the switch is closed. y applying the circuit principle above to the four possible combinations of input/output sinking/sourcing types, we have the four circuits as shown below. irectlogi Micro PLs provide all except the sourcing output I/O circuit types.

35 hapter : iscrete I/O Guidelines 0 I/O ommon Terminal oncepts In order for a PL I/O circuit to operate, current must enter at one terminal and exit at another. This means at least two terminals are associated with every I/O point. In the figure to the right, the Input or Output terminal is the main path for the current. One additional terminal must provide the return path to the power supply. If we had unlimited space and budget for I/O terminals, then every I/O point could have two dedicated terminals just as the figure above shows. However, providing this level of flexibility is not practical or even necessary for most applications. So, most Input or Output point groups on PLs share the return path among two or more I/O points. The figure to the right shows a group (or bank) of input points which share a common return path. In this way, the four inputs require only five terminals instead of eight. NOTE: In the circuit above, the current in the common path is equal to the sum of the energized channels. This is especially important in output circuits, where larger gauge wire is sometimes needed for the common. Some of the input and output modules often share a common return path. The best indication of I/O common grouping is on the wiring label. The combination I/O module to the right is an exception. The inputs and the outputs have separate commons. + + Field evice Main Path (I/O point) Return Path Input Input Input Input ommon PL PL I/O ircuit Input Sensing L0/0 Option Modules User Manual; th Ed., /0

36 hapter : iscrete I/O Guidelines onnecting I/O to Solid State Field evices In the previous section on Sourcing/Sinking concepts, we explained that I/O circuits sometimes will only allow current to flow one way. This is also true for many of the field devices which have solid-state (transistor) interfaces. In other words, field devices can also be sourcing or sinking. When connecting two devices in a series circuit, one must be wired as sourcing and the other as sinking. Solid State Input Sensors The PL inputs are flexible in that they detect current flow in either direction, so they can be wired as either sourcing or sinking. In the following circuit, a field device has an opencollector NPN transistor output. It sinks current from the PL input point, which sources current. The source can be a F-PS, + V, power supply or another supply (+ V or +V) of your choice, as long as the input specifications are met. Field evice Output (sinking) Ground Supply + ommon PL Input In the next circuit, a field device has an open-emitter PNP transistor output. It sources current to the PL input point, which sinks the current back to ground. Since the field device is sourcing current, no additional power supply is required. Field evice +V Output (sourcing) Ground Input (sourcing) Input (sinking) ommon PL Input Solid State Output Loads Sometimes an application requires connecting a PL output point to a solid state input on a device. This type of connection is usually made to carry a low-level signal, not to send power to an actuator. Some of the optional output modules are sinking-only. This means that each output provides a path to ground when it is energized. The six outputs of the L0 have the same electrical common, even though there are two common terminal screws. Not so with the L0 which has four isolated commons. Finally, recall that the output circuit requires power (0 V) from an external power source. In the following circuit, the PL output point sinks current to the output common when energized. It is connected to a sourcing input of a field device input.

37 hapter : iscrete I/O Guidelines 0 In the next example we connect a PL output point to the sinking input of a field device. This is a bit tricky, because both the PL output and field device input are sinking type. Since the circuit must have one sourcing and one sinking device, we add sourcing capability to the PL output by using a pull-up resistor. In the circuit below, we connect Rpull-up from the output to the output circuit power input. PL Output + pwr (sinking) NOTE: O NOT attempt to drive a heavy load (> m) with this pull-up method. NOTE : Using the pull-up resistor to implement a sourcing output has the effect of inverting the output point logic. In other words, the field device input is energized when the PL output is OFF, from a ladder logic point-of-view. Your ladder program must comprehend this and generate an inverted output. Or, you may choose to cancel the effect of the inversion elsewhere, such as in the field device. It is important to choose the correct value of Rpull-up. In order to do so, we need to know the nominal input current to the field device (I input) when the input is energized. If this value is not known, it can be calculated as shown (a typical value is m). Then use I input and the voltage of the external supply to compute Rpull-up. Then calculate the power Ppull-up (in watts), in order to size Rpull-up properly. I input = R pull-up = Of course, the easiest way to drive a sinking input field device as shown below is to use a sourcing output module. The arlington NPN stage will have about.

38 hapter : iscrete I/O Guidelines Relay Output Guidelines Relay outputs are available for the irectlogi PLs. Relays are best for the following applications: Loads that require higher currents than the solid-state outputs can deliver ost-sensitive applications Some output channels need isolation from other outputs (such as when some loads require different voltages than other loads) Some applications in which NOT to use relays: Loads that require currents under 0 m Loads which must be switched at high speed or heavy duty cycle Relay outputs in the irectlogi PLs and Relay with Form contacts modules are available in two contact arrangements, shown to the right. The Form type, or SPST (single pole, single throw) type is normally open and is the simplest to use. The Form type, or SPT (single pole, double throw) type has a center contact which moves and a stationary contact on either side. This provides a normally closed contact and a normally open contact. Relay with Form contacts Some relay output module s relays share common terminals, which connect to the wiper contact in each relay of the bank. Other relay modules have relays which are completely isolated from each other. In all cases, the module drives the relay coil when the corresponding output point is on. Prolonging Relay ontact Life Relay contacts wear according to the amount of relay switching, amount of spark created at the time of open or closure, and presence of airborne contaminants. However, there are some steps you can take to help prolong the life of relay contacts: Switch the relay on or off only when the application requires it. If you have the option, switch the load on or off at a time when it will draw the least current.

39 hapter : iscrete I/O Guidelines 0 Surge Suppression For Inductive Loads Inductive load devices (devices with a coil) generate transient voltages when de-energized with a relay contact. When a relay contact is closed it bounces, which energizes and de-energizes the coil until the bouncing stops. The transient voltages generated are much larger in amplitude than the supply voltage, especially with a supply voltage. When switching a -supplied inductive load the full supply voltage is always present when the relay contact opens (or bounces ). When switching an -supplied inductive load there is one chance in 0 (0 Hz) or 0 (0 Hz) that the relay contact will open (or bounce ) when the sine wave is zero crossing. If the voltage is not zero when the relay contact opens there is energy stored in the inductor that is released when the voltage to the inductor is suddenly removed. This release of energy is the cause of the transient voltages. When inductive load devices (motors, motor starters, interposing relays, solenoids, valves, etc.) are controlled with relay contacts, it is recommended that a surge suppression device be connected directly across the coil of the field device. If the inductive device has plug-type connectors, the suppression device can be installed on the terminal block of the relay output. Transient Voltage Suppressors (TVS or transorb) provide the best surge and transient suppression of and powered coils, providing the fastest response with the smallest overshoot. Metal Oxide Varistors (MOV) provide the next best surge and transient suppression of and powered coils. For example, the waveform in the figure below shows the energy released when opening a contact switching a V solenoid. Notice the large voltage spike. + V This figure shows the same circuit with a transorb (TVS) across the coil.

There are some steps you can take to help prolong the life of relay contacts, such as switching the relay on or off only when it is necessary, and if possible, switching the load on or off at a time when it will draw the least current. lso, take measures to suppress inductive voltage spikes from inductive loads such as contactors and solenoids. For inductive loads in circuits we recommend using a suppression diode as shown in the following diagram (O NOT use this circuit with an power supply). When the load is energized the diode is reverse-biased (high impedance). When the load is turned off, energy stored in its coil is released in the form of a negative-going voltage spike. t this moment the diode is forward-biased (low impedance) and shunts the energy to ground. This protects the relay contacts from the high voltage arc that would occur just as the contacts are opening. Place the diode as close to the inductive field device as possible. Use a diode with a peak inverse voltage rating (PIV) at least 00 PIV, forward current or larger. Use a fast-recovery type (such as Schottky type). O NOT use a small-signal diode such as N, N, etc. e sure the diode is in the circuit correctly before operation. If installed backwards, it short-circuits the supply when the relay energizes.

The dual diodes (shown to the right) allow current to flow in either direction. The inputs accept 0.. V. The target applications are + V and + V. You can actually wire half of the inputs as sinking and the other half as sourcing. Inputs grouped by a common must be all sinking or all sourcing. Input ommon PL Input Output Wiring Methods The PL output circuits are high-performance transistor switches with low on-resistance and fast switching times. Please note the following characteristics which are unique to the output type: The L0 has only one electrical common for all six outputs. ll six outputs belong to one bank. The L0 output switches are current-sinking only. However, you can still use different voltages from one load to another. The L0 has isolated commons for each group of four outputs. There are two L0 models with output switches that are current-sinking only, and one that has sourcing output switches. The output circuit inside the PL requires external power. The supply ( ) must be connected to a common terminal, and the supply (+) connects the the right-most terminal on the upper connector. Firmware and Software The discrete option modules will only function properly in a L0 with firmware version V.0 (or later). If you have a L0 with an earlier firmware version, the latest version can be downloaded from our website, If you are unable to download the latest firmware version along with the upgrade support tool software, call our technical support group to arrange to have your PL upgraded. The L0 PLs need to have irectsoft Version.0c (or later) in order for the analog feature to perform properly. The L0 must use irectsoft Version.0 in order to use the option modules.

The module ships with the jumper not connecting the two pins. In this position, the expected input signal is 0m. To select 0 0m signals, use the jumper to cover both pins. The default jumper setting selects a 0m signal source. The default jumper setting does not connect the two pins. WRNING: efore removing the analog module or the terminal block on the face of the module, disconnect power to the PL and all field devices. Failure to disconnect power can result in damage to the PL and/or field devices. onnecting and isconnecting the Field Wiring Wiring Guidelines Your company may have guidelines for wiring and cable installation. If so, you should check those before you begin the installation. Here are some general things to consider: Use the shortest wiring route whenever possible. Use shielded wiring and ground the shield at the transmitter source. o not ground the shield at both the module and the source. o not run the signal wiring next to large motors, high current switches, or transformers. This may cause noise problems. Route the wiring through an approved cable housing to minimize the risk of accidental damage. heck local and national codes to choose the correct method for your application. The F0 0 does not supply power to field devices. You will need to power transmitters separately from the PL. To remove the terminal block, disconnect power to the PL and the field devices. Pull the terminal block firmly until the connector separates from the module. You can remove the analog module from the PL by folding out the retaining tabs at the top and bottom of the module. s the retaining tabs pivot upward and outward, the module s connector is lifted out of the PL socket. Once the connector is free, you can lift the module out of its slot. OFF = 0 J L0/0 Option Modules User Manual; th Ed., /0

The F0-0- provides ohm resistance for each channel. If your transmitter requires a load resistance below ohms, you do not have to make any changes. However, if your transmitter requires a load resistance higher than ohms, you need to add a resistor in series with the module. onsider the following example for a transmitter being operated from a 0 V supply with a recommended load resistance of 0 ohms.

This enables the module to continuously provide accurate measurements without slowing down the discrete control logic in the RLL program. The module takes approximately milliseconds to sense % of the change in the analog signal. For the vast majority of applications, the process changes are much slower than these updates. NOTE: If you are comparing other manufacturers update times (step responses) with ours, please be aware that some manufacturers refer to the time it takes to convert the analog signal to a digital value. Our analog to digital conversion takes only a few microseconds. It is the settling time of the filter that is critical in determining the full update time. Our update time specification includes the filter settling time. L0/0 Option Modules User Manual; th Ed., /0

Loading a constant of 00 into V00 identifies a channel analog input module is installed in the L0 option slot, and reads the input data values as numbers. Loading a constant of 00 into V00 identifies a channel analog input module is installed in the L0 option slot, and reads the input data values as binary numbers. V00 V0 Structure of V0 V0 is a system V memory location used as a pointer to a user V-memory location where the analog input data is stored. The V memory location loaded into V0 is an octal number identifying the first user V-memory location for reading the analog input data. This V memory location is user selectable. For example, loading O000 causes the pointer to write h s data value to V000, h s data value to V00, h s data value to V00, and h s data value to V00.

The example program below shows how to setup these locations. This rung can be placed anywhere in the ladder program or in the initial stage if you are using stage programming instructions. This is all that is required to read the analog input data into V-memory locations. Once the data is in V-memory you can perform math on the data, compare the data against preset values, and so forth. V000 is used in the example but you can use any user V-memory location. SP0 L K00 - or - L K00 V00 L O000 V0 Loads a constant that specifies the number of channels to scan and the data format. The upper byte selects the data format (i.e. 0=, =inary) and the number of channels (set to for the F0 0 ). The binary format is used for displaying data on some operator interface units. The L0 PLs support binary math functions. Special V-memory location assigned to the option slot contains the data format and the number of channels to scan. This loads an octal value for the first V-memory location that will be used to store the incoming data. For example, the O000 entered here would designate the following addresses. h V000, h V00, h V00, h V00 The octal address (O000) is stored here. V0 is assigned to the option slot and acts as a pointer, which means the PU will use the octal value in this location to determine exactly where to store the incoming data. 0 L0/0 Option Modules User Manual; th Ed., /0

The Special Relays described on page allow you to use this feature in your ladder program. For example, in the rung below SP0 is used to pull-in coil Y, which would be used to open or close an external circuit. SP0 NOTE: The F0 0 analog module cannot sense the loss of analog input signals in 0 0m loops. See page for information about setting the jumper to select your input type. Scale onversions Scaling the Input ata Many applications call for measurements in engineering units, which can be more meaningful than raw data. onvert to engineering units using the formula shown to the right. You may have to make adjustments to the formula depending on the scale you choose for the engineering units. For example, if you wanted to measure pressure (PSI) from 0.0 to. then you would have to multiply the analog value by 0 in order to imply a decimal place when you view the value with the programming software or a handheld programmer. Notice how the calculations differ when you use the multiplier. nalog Value of 0, slightly less than half scale, should yield.

The module takes approximately 0. milliseconds to sense % of the change in the analog signal per channel. It takes approximately. ms to sample all channels if channels are used (0. ms X channels =. ms). NOTE: If you are comparing other manufacturers update times (step responses) with ours, please be aware that some manufacturers refer to the time it takes to convert the analog signal to a digital value.

This enables the module to continuously provide accurate measurements without slowing down the discrete control logic in the RLL program. The module takes approximately 0 milliseconds to sense % of the change in the analog signal. For the vast majority of applications, the process changes are much slower than these updates. NOTE: If you are comparing other manufacturers update times (step responses) with ours, please be aware that some manufacturers refer to the time it takes to convert the analog signal to a digital value.

This enables the module to continuously provide accurate measurements without slowing down the discrete control logic in the RLL program. The module takes approximately 0. milliseconds to sense % of the change in the analog signal per channel. It takes approximately. ms to sample all channels if channels are used (0. ms X channels =. ms). NOTE: If you are comparing other manufacturers update times (step responses) with ours, please be aware that some manufacturers refer to the time it takes to convert the analog signal to a digital value. Our analog to digital conversion takes only a few microseconds. It is the settling time of the filter that is critical in determining the full update time.

Most applications use measurements in engineering units, so it is usually necessary to convert from engineering units to a suitable output value. The conversion to an output value can be accomplished by using the conversion formula shown. You will need to substitute the engineering units for your scale into the formula to the right. For example, if you want to output pressure (PSI) between 0.0 and 00.0, you may multiply the pressure value by 0 to store in a V-memory location and eliminate the decimal point.

Use shielded wiring and ground the shield at the transmitter source. o not ground the shield at both the module and the source. Unused channels require shorting wires (jumpers) installed from terminals H+ to H to OM. o not run the signal wiring next to large motors, high current switches, or transformers. This may cause noise problems. Route the wiring through an approved cable housing to minimize the risk of accidental damage. heck local and national codes to choose the correct method for your application. To remove the terminal block, disconnect power to the PL and the field devices. Pull the terminal block firmly until the connector separates from the module. You can remove the RT module from the PL by folding out the retaining tabs at the top and bottom of the module. s the retaining tabs pivot upward and outward, the module s connector is lifted out of the PL socket. Once the connector is free, you can lift the module out of its slot. Use the following diagram to connect the field wiring. If necessary, the F0 0RT terminal block can be removed to make removal of the module possible without disturbing field wiring. RT - Resistance Temperature etector Use shielded RTs whenever possible to minimize noise on the input signal. Ground the shield wire at one end only, preferably at the RT source. Lead onfiguration for RT Sensors The suggested three-lead configuration shown below provides one lead to the H+ terminal, one lead to the H terminal, and one lead to the common terminal. ompensation circuitry nulls out the lead length for accurate temperature measurements. Some sensors have four leads. When making connections, do not connect the second lead to the H+ input; leave that lead unconnected. o not use configurations that lack the use of the same color lead to both the H and OM terminals.

249 hapter : F0-0RT -hannel RT Input Negative Temperature Readings with Magnitude Plus Sign With bipolar ranges, you need some additional logic to determine whether the value being returned represents a positive temperature or a negative temperature. There is a simple solution: If you are using bipolar ranges and you get a value greater than or equal to 000 H, the value is negative. If you get a value less than or equal to FFF H, the value is positive. The sign bit is the most significant bit, which combines 000 H to the data value. If the value is greater than or equal to 000 H, you only have to mask the most significant bit and the active channel bits to determine the actual data value. The following two programs show how you can accomplish this. The first example uses magnitude plus sign (binary) and the second example uses magnitude plus sign (). Since you always want to know when a value is negative, these rungs should be placed before any other operations that use the data, such as math instructions, scaling operations, and so forth. lso, if you are using stage programming instructions, these rungs should be in a stage that is always active. Note: you only need this logic for each channel that is using bipolar input signals. The examples only show two channels.
