Communication Module adds Profibus connection to PLC.
Press Release Summary:
December 10, 2012 - Adding 9-pin Sub-D socket connector to versions of S7-1500 controller which have no integrated interface, Simatic CM 1542-5 allows communication with lower-level Profibus devices in bandwidths from 9.6 Kbps to 12 Mbps. Module can also be used to implement separate Profibus lines to control field devices via Profibus segments. Assuming all communication tasks in process, Simatic CM 1542-5 minimizes load on controller's CPU. All functions are configured via TIA Portal v12.

Siemens Adds Profibus Module to New Simatic Controller
Press release date: November 27, 2012
The new communication module can be used as a time master or time slave for synchronizing the time of day within the plant. When used as a time master, the module forwards the time specified by the controller to the connected peripheral devices via Profibus. When used as a time slave, it receives time-of-day frames from the network and forwards them as the valid time for the S7-1500 station.
Simatic 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 controller and other devices, for example those from the Simatic-S7-300/400 range.
