The CP 1542-5 communications module expands the SIMATIC S7-1500 controller line, providing a PROFIBUS connection for communication with lower-level PROFIBUS devices in bandwidths of 9.6 kBit/s to 12 MBit/s. The module also enables the implementation of separate PROFIBUS lines, i.e. the control of multiple field devices via several PROFIBUS segments.
The CP 1542-5 offloads the communication task from the main CPU since it has its own microprocessor. As a decentralized peripherals DP master, the module supports the analysis of the PROFIBUS bus topology in a DP master system by means of diagnostic repeater (DP-Slave). 32 DP slaves can be connected.
The Compact hardware mounts to the S7-1500 mounting rail and connects to the adjacent modules via the bus connectors included in the package. It can be configured with the STEP 7 Professional TIAPortal V12 SP1 or higher version. Three LEDs indicate the operating and communication status of the module. The CP 1542-5 can be replaced without a PG/PC.
For PROFIBUS networks which require more than 32 DP slaves, the CM 1542-5 is recommended. The CM 1542-5 supports 125 PROFIBUS DP slaves.
