SIMATIC S7-1200 Integrierte Kommunikation

The use of the SIMATIC S7-1200 as a master or slave on the proven PROFIBUS field bus facilitates standardized communication from the field level through to the control level. This meets one of the most important requirements in the performance range of compact automation.
For the connection of the S7-1200 to PROFIBUS there are two communication modules (CMs): The DP-Master CM 1243-5 enables as many as 16 field devices to be connected as slaves, e.g. ET 200 distributed I/O modules. Together with the CM 1242-5, the S7-1200 functions as a DP-Slave and can thus be connected to any DP-Master. Both modules are readily connected on the left of the CPU via the backplane bus.
