Overview
The CM 1542-5 communications module adds a PROFIBUS connection to the SIMATIC S7-1500 controller for communication with lower-level PROFIBUS devices at transfer rates of 9.6 Kbps to 12 Mbps. The module can also be used to implement separate PROFIBUS lines, in other words, to control a number of different field devices via a number of PROFIBUS segments. The CM 1542-5 assumes all communication tasks, thus reducing the CPU workload.
The CM 1542-5 is suitable for S7 communication as well as for conventional PROFIBUS communication. This makes it possible to establish communication between the S7-1500 PLC and other devices, for example those from the SIMATIC S7-300/400 range.
- PROFIBUS DP master or DP slave with electrical interface for connecting the SIMATIC S7-1500 to PROFIBUS at up to 12 Mbps (including 45.45 Kbps)
- Communications services:
- PROFIBUS DP
- PG/OP communication
- S7 communication
- Open user communication (SEND/RECEIVE) via FDL
- Time synchronization
- Simple programming and configuration over PROFIBUS
- Cross-network PG communication using S7 routing
- Module replacement without programming device/engineering station
- Data record routing (PROFIBUS DP)
- Adding or modifying distributed I/O during operation
Hardware innovations of the CM 1542-5 product with new article number 6GK7542-5DX10-0XE0 extend the permissible ambient temperature for operation from -25 °C to 60 °C (no condensation or icing) for a horizontally mounted rack and -25 °C to 40 °C (no condensation or icing) for a vertically mounted rack.
Furthermore, the permissible installation altitude for the CM 1542-5 module (6GK7542-5DX10-0XE0) has been extended to installation altitudes of up to 5000 m.
Benefits
- Particularly suitable for closed-loop control tasks thanks to SYNC/FREEZE and constant bus cycle
- Sub-process-oriented design of an automation solution through the use of several CMs
- Universal application of the CM due to the parallel use of different communications services on one CM
Application
The CM 1542-5 is the communication module of the SIMATIC S7-1500 for the PROFIBUS bus system. It relieves the CPU of communication tasks and supports additional connections.
SIMATIC S7-1500 communication options via communication modules:
- As master for PROFIBUS DP according to IEC 61158/EN 50170
- Communication with programming devices and HMI devices
- Communication with other SIMATIC S7 systems
- Communication with SIMATIC S5 programmable controllers
The number of CMs that can be operated depends on the CPU type and on the communication services used.
Design
The CM 1542-5 communications module features all the advantages of the SIMATIC S7-1500 design:
- Compact design:
- 9-pin D-sub socket for connection to PROFIBUS DP
- The module is supplied with power via the integrated backplane bus
- Three LEDs to indicate the operational and communication status
- Simple installation:
The CM 1542-5 is mounted on the S7-1500 mounting rail and connected to the other S7-1500 modules by means of the bus connectors. The slot rules of the S7-1500 system apply. - User-friendly wiring:
the D-sub socket is easily accessible and simple to use. - The CM 1542-5 can be operated without a fan. A backup battery is not required.
- The module can be replaced without a programming device or engineering station.
Function
The CM 1542-5 supports the following communications services:
- PROFIBUS DP Master Class 1
- PROFIBUS DP (according to IEC 61158/61784)
- SYNC/FREEZE: The outputs or inputs can be synchronized from the user program with the DPSYNC_FR system function.
- PROFIBUS DP slave (not parallel to DP master)
- PG/OP communication
- S7 communication
- Open user communication via FDL
- Time synchronization via PROFIBUS
Master for PROFIBUS DP
The CM 1542-5 operates as DP-V1 master. It handles data transfer independently and allows slaves to be connected, such as the CM 1242-5 as a DP slave, DP slaves of the ET 200 distributed I/O system, etc. This means that the CM 1542-5 is able to connect the S7-1500 station to PROFIBUS DP and is the ideal expansion to the integrated DP master interfaces of the S7-1500 CPUs (CPU 1516 and larger) for establishing additional PROFIBUS DP lines.
The CM 1542-5 is a DP-V1 master; in other words, it also supports the acyclic standard services, including alarm handling. The CM 1542-5 also supports the functions SYNC and FREEZE, constant bus cycle time and data record routing.
During operation, it is also possible to activate or deactivate DP slaves. Among other things, this allows the step-by-step commissioning of subprocesses.
A diagnostic repeater allows the line to be diagnosed during operation, enabling line faults to be detected at an early stage. The CM 1542-5 supports operation with a diagnostic repeater (including activation of topology identification on the diagnostic repeater).
The distributed I/O is handled like the centralized I/O from the user’s point of view. This means that there are no differences between the CM 1542-5 and the integrated DP master interface of the S7-1500 CPU in terms of configuration and parameter assignment. Regardless of the scale of the system, the CM 1542-5 has extremely short response times.
PG/OP communication
PG/OP communication allows all S7 stations connected to the network to be remotely programmed.
- S7 routing: With the aid of routing it is possible to use programming device communication across different networks.
S7 communication
S7 communication is used for the coupling
- between SIMATIC S7 automation systems
- and programming devices (PG/OP communication)
- to PCs, e.g. CP 5711 with SOFTNET-PB S7, CP 5623 etc.
- and HMI devices (OPs)
Open user communication (SEND/RECEIVE) via FDL
Based on Layer 2 (FDL) of PROFIBUS, the CM 1542-5 offers a simple, optimized interface for process or field communication.
This interface offers integrated, high-performance communication between SIMATIC S5, SIMATIC S7, SIMATIC 505 and PC. SEND/RECEIVE provides not only the SDA service (PLC/PLC connections) but also the SDN service (broadcast, multicast).
The communication partners are the automation systems:
- SIMATIC S7
with CM 1542-5, CP 342-5, CP 343-5, CP 443-5 Extended and Basic - SIMATIC S5
with S5-95U with PROFIBUS interface, S5-115U/H, S5-135U, S5-155U/H with CP 5431 FMS/DP - SIMATIC 505
with CP 5434-FMS - PCs
with CP 5512, CP 5611 A2, CP 5621, CP 5613 A3, CP 5613 FO, CP 5614 A3, CP 5623, CP 5624 - Systems of other makes that are equipped with an FDL interface.
To use SEND/RECEIVE, function calls are required (TSEND/TRCV), which must be integrated into the STEP 7 user program.
Time synchronization
Time synchronization is used to set the time of day throughout the plant.
The CM 1542-5 is capable of forwarding the time of day of the S7-1500 CPU to PROFIBUS. Conversely, the CM of the S7-1500 CPU can make an existing time on PROFIBUS available.
The CM 1542-5 supports:
- Time status value, daylight-saving time changeover, synchronization status
Data record routing
The CM 1542-5 supports the data record routing function. With this option, the CM can be used as a router for data records that need to be sent to field devices (DP slaves). Data records from devices that are not connected directly to PROFIBUS and therefore have no direct access to the DP slaves are forwarded to the DP slaves by the CM.
Diagnostics
Extensive diagnostic options are available with STEP 7 Professional V14 (TIA Portal), including:
- Operating status of the CM
- General diagnostics and statistics functions
- Connection diagnostics
- Bus statistics
- Message buffer
- Support of operation with diagnostic repeater
Configuration
STEP 7 Professional V14 (TIA Portal) or higher is required for configuring the full range of functions of the CM 1542-5. The configuration data of the CM is always saved on the CPU and retained even after a PLC failure. A module can therefore be replaced without having to reload the configuration data from a programming device. The CPU transfers the configuration data to the CM during startup.
Configuration and programming of all SIMATIC S7 controllers connected to the network is possible over the network.
STEP 7 Professional V18 (TIA Portal) or higher is required for configuring the full range of functions of the new product CM 1542-5 (6GK7542-5DX10-0XE0).
The product CM 1542-5 (6GK7542-5DX10-0XE0) can also be used in existing SIMATIC S7-1500 systems that have been configured with earlier versions of STEP 7 Professional (TIA Portal). In this case the CM 1542-5 (6GK7542-5DX10-0XE0) product must be configured as CM 1542-5 (6GK7542-5DX00-0XE0) in STEP 7 Professional.
