Siemens CP342-5 Module

Manufacturer: Siemens

The CP 342-5 is the communications processor of the SIMATIC S7-300 for the PROFIBUS DP bus system.

The CP 342-5 relieves the CPU from communication tasks.

The CP 342-5 operates as a DP-V0 Master according to IEC 61158/EN 61784 Volume 2 and processes the data transfer completely independently. It supports the services of the Master Classes 1 and 2.

The CP 342-5 as a DP-V0 slave permits the SIMATIC S7-300 to exchange data with other PROFIBUS DP masters. which allows a hybrid setup between SIMATIC S5/S7, PCs, ET 200 and other field devices to PROFIBUS DP. Function calls are required for the DP communication. These (DP-SEND/DP-RECV) must be integrated in the STEP 7 user program.
