9 Introduction Philosophy of the ECOFAST system The ECOFAST system (Energy and Communication Field Installation System) sets new standards whenever machines and plant need to be equipped with automation, control, and drive technology. The central pillars of the ECOFAST philosophy are extensive decentralization and modularization of the installation system and comprehensive diagnostics on the component level. ECOFAST links all of the components of an automation system together using an integrated connection technique for data and power that complies with the high IP65 degree of protection. ECOFAST is therefore an integral element of Totally Integrated Automation and open for manufacturers and users. Hybrid Siemens fieldbus interface Drives & PLCs Manual, 10/2010, A5E

10 Introduction 1.1 Philosophy of the ECOFAST system 10 Manual, 10/2010, A5E

11 Description Tasks Tasks A hybrid fieldbus interface forms a pluggable and unpluggable interface between the control cabinet / terminal box (IP20) and the fieldbus level (IP65 / 67) in the ECOFAST system or in a PROFIBUS DP system. Characteristics: Control cabinet gland to IP65 / 67 field installations 2 interface types (hybrid or M12 connection) on the IP65 / 67 field side 2 different versions (active or passive) Automatic, continuous baud rate detection (active version) PROFIBUS FMS / DP (acc. to EN / EIA-RS 485) 3 electrically isolated segments with signal regeneration (active version) Infeed or looping of the 24 V DC auxiliary voltages Terminal block with spring terminals permits a large number of possible auxiliary voltage connections 2.2 Versions versions s are available in two different versions: active or passive. Active means: Active connection from RS 485 two-wire bus cables, e.g. PROFIBUS DP between segments 1, 2, and 3 with signal regeneration (signal refresher). The individual segments (S1, S2, S3) of this version are also electrically isolated. Special feature: No bus terminating connector is required for unused segments (either on the field side or on the control cabinet side for a sub-d connector). Note: Unused terminals must be sealed with a covering cap in order to comply with the IP67 degree of protection. Hybrid Siemens fieldbus interface Drives & PLCs Manual, 10/2010, A5E

12 Description 2.3 Power supply Passive means: The signals are not regenerated. The control cabinet side and the IP65 / 67 field side are electrically connected. Note Compliance with the IP67 degree of protection Unused terminals must be sealed with a covering cap in order to comply with the IP67 degree of protection. 2.3 Power supply Power supply The data cable and the 24 V DC supply voltage for the ECOFAST components are carried together in the hybrid cable. The power supply is formed by: Non-switched 24 V DC supply voltage (NS) This voltage is also required to supply the internal electronics of the active versions It can also be conducted and looped. Switched 24 V DC supply voltage (S) This voltage can also be conducted and looped. The corresponding "function" can be "marshaled" on the terminal block on the control cabinet side. Note Power supply A voltage drop calculation must be performed according to the cable length, the cable crosssection, and the actual current flow, in order to guarantee the minimum supply voltage to the ECOFAST components. 12 Manual, 10/2010, A5E

13 Description 2.4 Design passive version 2.4 Design passive version Passive version The hybrid fieldbus interfaces have a two-channel design. Two Han-Brid connections (S1 and S2) are provided on the field side (IP65 / 67 side). The control cabinet side has two direct or two Fast Connect connections, depending on the version. The data (RS 485) simply passes through. Note Bus connection The cables must always be connected on the inside and the corresponding outside of the bus because the bus is otherwise open (i.e. not terminated). The voltages present in the hybrid cable (2 x 24 V DC) are supplied to the terminal block, where they can be connected according to the application. IP20 S1 S2 S1 S2 IP65 Figure 2-1 Block diagram: Passive hybrid fieldbus interface, two-channel Hybrid Siemens fieldbus interface Drives & PLCs Manual, 10/2010, A5E

14 Description 2.5 Design active version 2.5 Design active version Active version This hybrid fieldbus interface consists of three active segments. There is an active connection with signal regeneration between segments S1, S2, and S3. However, the individual segments are electrically isolated. Two Han-Brid connections, which are assigned to segments S1 and S2, are provided on the field side (IP65 / 67 side). The control cabinet side has a 9-pole sub-d connector for segment S1. Special feature: No bus terminating connector is required for unused segments (either on the field side or on the control cabinet side for a sub-d connector). The voltages present in the hybrid cable (2 x 24 V DC) are supplied to the terminal block, where they can be connected according to the application. The 24 V DC voltage (NS) for the internal electronics of the hybrid fieldbus interface is supplied either via segment S2 or via the terminal block. The operating states are indicated by two LEDs: Green for the power supply Yellow for baud rate detection The baud rate is continuously monitored, and automatically detected and set. IP20 S S2 S3 IP65 Figure 2-2 Block diagram: Active hybrid fieldbus interface, 3 segments 14 Manual, 10/2010, A5E

15 Description 2.6 Version with M12 sockets 2.6 Version with M12 sockets with M12 sockets Another version of the hybrid fieldbus interface described above has M12 sockets on the IP65 / 67 side instead of the hybrid connections. This version functions identically to the version with hybrid connections. The 24 V DC voltage (NS) for the internal electronics of the hybrid fieldbus interface must always be supplied via the terminal block. IP20 S S2 IP65 S3 Figure 2-3 Block diagram: Active hybrid fieldbus interface, two M12 sockets Hybrid Siemens fieldbus interface Drives & PLCs Manual, 10/2010, A5E

16 Description 2.6 Version with M12 sockets 16 Manual, 10/2010, A5E

17 Use Use of hybrid fieldbus interfaces Infeed or looping of data from the control cabinet to the field Infeed or looping of data from the control cabinet to the field via RS 485, shielded copper (Cu) cable. Two phases are possible per module passive version. The version with two M12 sockets is designed for the infeed function (from the control cabinet to the field) when no 24 V DC is carried (PROFIBUS cable only) or Looping of data via RS 485, shielded copper (Cu) cable Looping of 2 x 24 V DC, switched (S) and non-switched (NS) Signal regeneration (signal refresher) for the "active version" Note ECOFAST hybrid fieldbus cable ECOFAST hybrid fieldbus cables are trailing-type cables. They have two shielded copper cores for PROFIBUS DP and four 1.5 mm² copper cores for the 24 V DC switched (DC 24 V, -S) and 24 V DC non-switched (DC 24 V, -NS).

For information about stripped lengths, cross-sections, and terminal assignments, refer to chapter Stripped lengths, cross-sections, terminal assignment (Page 30). 2 Connect the cables for 24 V DC switched (S) and non-switched (NS) to the 24 V DC terminal block with spring terminals., passive, active 3 Connect the cables for PROFIBUS DP to the A1 / B1 and A2 / B2 terminals with spring terminals. or Connect the cables to the Fast Connect block. 4 Connect the shields to the shield terminals. 5 This completes the wiring. Wiring of the hybrid fieldbus interface Connect the PROFIBUS DP cable to the 9-pole sub-d socket. Table 5-1 "Fast Connect" connection sequence Step Description 1 Prepare the bus cable as shown in the drawing opposite. Don't strip the cable ends! Loosen the screw plug, then lift up the cover and open the terminal block. Hybrid Siemens fieldbus interface Drives & PLCs Manual, 10/2010, A5E

28 Connections and versions 5.9 Description of the 24 V DC terminal block Step Description 3 Insert the cable ends into the terminal and press the terminal block down again to close it. The bus cable is now contacted owing to the insulation piercing connecting device. 4 Close the cover again and screw the plug tight. The pressure exerted by the cover causes the shield to be contacted and relieves the strain on the cable. 5 This completes the wiring. Wiring the Fast Connect connection 5.9 Description of the 24 V DC terminal block Description of the 24 V DC terminal block The hybrid fieldbus interface allows the 24 V DC switched (+S and -S) or non-switched (+NS and -NS) that is present in the hybrid cable to be fed (infeed) or looped (looping) to the field. The terminals on the terminal block take the form of "spring terminals". The terminal block consists of three terminal strips arranged one above the other. Two electrically connected terminal strips are provided for the IP67 segment on the left (S1 for a passive hybrid fieldbus interface or S2 for an active interface). Infeed: If the infeed function is selected, power can be supplied on the upper terminal strip, for instance. It is also possible to select the infeed function separately for each segment even via a separate power supply unit. To do this, the separate voltages must be connected on the terminal block of the segments concerned. Wire jumpers must be inserted between the middle and the lower terminal strips in order to connect the segments together. S1 is connected to S2 for a passive hybrid fieldbus interface or S2 to S3 for an active interface. 28 Manual, 10/2010, A5E

29 Connections and versions 5.10 M12 version description of the terminal block Looping: With the looping function, the 24 V DC of one segment must be connected to the other segment. To do this, the individual segments on the terminal block (middle and lower terminal strips) must be connected together by inserting wire jumpers.

The same applies to the 9-pole sub-d connection. On the other hand, if one or more nodes are connected to a segment, the bus must be terminated at the last node either by connecting the bus terminator or by inserting an ECOFAST terminating connector. Note IP65 / 67 degree of protection However, dust / sealing caps must be provided for any outgoing feeders that are not used in order to comply with the IP65 / 67 degree of protection Design and topology The installation guidelines for the PROFIBUS DP must be heeded at all times. Only a linear, star, or tree topology is allowed. Ring topologies are not permitted. The maximum cascading depth and the maximum bus cable length corresponding to the baud rate must not be exceeded.

49 Glossary AC 3 current for contactors The AC 3 current for contactors is the rated operational breaking current while squirrel cage a motor is running. Baud rate The baud rate is the speed at which data is transmitted. It specifies the number of bits transferred per second (bit rate). PROFIBUS DP supports baud rates from 9.6 kbaud to 12 Mbaud. Bus Shared data transmission path to which all nodes are connected. It has two defined ends. In the case of PROFIBUS, the bus is a two-wire line (copper cable) or a fiber optic conductor. Bus segment -> Segment Bus system All stations physically connected to a bus cable form a bus system. Current limit You can enter a lower and / or an upper current limit value. Example: "Substance for mixing is too thick", i.e. the current exceeds the upper current limit. "No-load operation because drive belt is broken", i.e. the current undershoots the lower current limit. The current limits and the blocking protection are not activated (start override) until the class time expires, e.g. after 10 seconds for class 10. If the current limits are exceeded or undershot, the motor starter responds by either switching off or issuing a warning. Range for lower current limit: 20% to 100% of the rated operational current. Range for upper current limit: 50% to 150% of the rated operational current. Hybrid Siemens fieldbus interface Drives & PLCs Manual, 10/2010, A5E

Two data tee connectors are used in the ECOFAST system for: PROFIBUS DP with copper cable (PROFIBUS DP Cu) PROFIBUS DP with fiber optic conductor (PROFIBUS DP LWL) DESINA Distributed and standardized installation technology for machine tools: German Machine Tool Builders' Association, whose aim is to define a standard for the assembly and installation methods employed for machine tool components. Device master data Device master data (GSD) contains DP slave descriptions in a standardized format. The use of GSD files makes it easier to configure the master and the DP slave. DP master A master with characteristics to EN , Volume 2, PROFIBUS with the DP protocol is referred to as the DP master. DP slave A slave operated on the PROFIBUS with the PROFIBUS DP protocol that behaves in accordance with EN , Volume 2, PROFIBUS is referred to as the DP slave. DP standard The DP standard is the bus protocol of the ET 200 distributed I/O system based on the EN standard, Volume 2, PROFIBUS. ECOFAST (Energy and Communication Field Installation System): A system that extensively decentralizes and modularizes installation systems and facilitates comprehensive diagnostics on the component level. ECOFAST certified Certifies the conformity of equipment from different manufacturers with the ECOFAST specification. ECOFAST ES The ECOFAST ES configuration tool supports the power engineering design of the system. 50 Manual, 10/2010, A5E

51 Glossary ECOFAST integrated Devices from other manufacturers can also be integrated into the ECOFAST ES configuration tool in addition to the Siemens components. Their integration and conformity are confirmed by the ECOFAST integrated certificate. Host A host is a system or device containing at least one DP master, e.g. the programmable controller with the CPU is the host and the IM 308-C is the DP master. Hybrid fieldbus connector The hybrid fieldbus connector represents the physical connection between the station and the bus cable. IM 308-C The IM 308-C is a DP master for the ET 200 distributed I/O system. The IM 308-C can be used together with COM PROFIBUS and plugged into the S5-115U, S5-135U, and S5-155U programmable controllers. IrDA Infrared Data Association: = standard for infrared interface drivers. Load feeder A load feeder is a spur line from the main circuit to the load with "switching" and "protection" functions. The "protection" function comprises: Protecting the line from the load feeder to the load (line protection), and Protecting the load against overload (load protection). Master When a master is in possession of the token, it can send data to other nodes and request data from other nodes (= active node). Master / slave mode Bus access method where only one node is master and all other nodes are slaves. Master interface Module for the distributed installation system. The distributed I/Os are "connected" to the programmable controller via the C master interface. Hybrid Siemens fieldbus interface Drives & PLCs Manual, 10/2010, A5E

52 Glossary Master system All of the slaves that are assigned to a master with read and write access form a master system together with this master. Power bus Linear main power distribution system. Power tee clamp connector Power tee clamp connectors connect ECOFAST components to the power bus. The power bus is not interrupted if a component is unplugged. Process image An "image" of the states of all inputs (= PII) or all outputs (= PIO) at a given moment in time. You can access the process image in the control program. PROFIBUS PROcess FIeld BUS, a European process and fieldbus standard defined in the PROFIBUS standard (EN , Volume 2, PROFIBUS). It specifies the functional, electrical and mechanical characteristics of a bit-serial fieldbus system. PROFIBUS is a bus system that connects PROFIBUS compatible automation systems and field devices on the cell and field levels. PROFIBUS is available with the DP (= Distributed Peripherals), FMS (= Fieldbus Message Specification), PA (Process Automation), or TF (= Technological Functions) protocol. PROFIBUS address To identify it uniquely, each station must be assigned a PROFIBUS address. PCs/PGs and the ET 200 handheld have the PROFIBUS address "0". Masters and slaves have a PROFIBUS address between 1 and 125. PROFIBUS DP PROFIBUS bus system with the DP (Distributed Peripherals) protocol. The main task of PROFIBUS DP is to manage the fast, cyclic data exchange between the central DP master and the I/O devices. Segment The bus cable between two terminating resistances forms a segment. Each segment contains between 0 and 32 stations. Segments can be linked by means of RS 485 repeaters or active fieldbus interfaces (signal refreshers). 52 Manual, 10/2010, A5E

53 Glossary Slave A slave is only allowed to exchange data with a master after this master has requested it to do so. Slaves include all DP slaves, such as motor starters, frequency converters etc. Station A station is a device that can send, receive, or amplify data over the bus. It can be a master, slave, RS 485 repeater, active star coupler etc. Station number -> PROFIBUS address Terminating resistance Every bus cable that connects individual devices together must be terminated with a resistor at both ends. These resistors serve to prevent reflection on the lines. Hybrid Siemens fieldbus interface Drives & PLCs Manual, 10/2010, A5E
