Siemens CP342-5FO Module
Manufacturer: Siemens

The CP 342-5 FO operates as a DP-V0 Master according to IEC 61 158/EN 50 170 Volume 2 and processes the data transfer completely independently. It supports the services of the Master Classes 1 and 2.

The CP 342-5 FO as a DP-V0 Slave allows the SIMATIC S7-300 to exchange data with the SIMATIC S7-400 and with other PROFIBUS DP masters via the OBT. which allows a hybrid setup between SIMATIC S5/S7, PCs, ET 200 and other field devices to PROFIBUS DP. Function calls are required for DP communication, both as master and as slave. These (DP-SEND/DP-RECV) are shipped with STEP 7 and must be integrated in the user program.

Features Applications Model
  • The fiber-optic technology is used when the environment is subject to strong EMC interference,
  • strong potential differences exist and high transmission rates are required.
  • The CP 342-5 FO is connected directly to the optical PROFIBUS and is therefore specially suited to harsh industrial environments
  • Expansion of the process I/O at SIMATIC S7-300 by several PROFIBUS DP interfaces
  • Optimization of Applicaiton and many application options through sending of data with S7 communication
  • Comprehensive control and monitoring through multiplex function with OP communication
  • Suitable for closed loop control tasks due to SYNC and FREEZE.
  • The CP 342-5 FO is the communications processor of the SIMATIC S7-300 for the PROFIBUS DP optical bus system.
  • The CP 342-5 FO has a fiber optic interface that facilitates interference-immune connections even in environments with severe levels of radio interference.
  • It relieves the CPU of communications tasks.
  • Communication of the SIMATIC S7-300 with the distributed I/O system ET 200 with integral optical interface
  • SIMATIC S7-400 with IM 467 FO and CP 342-5 FO
  • PC with CP 5613 FO
  • Remaining PROFIBUS nodes via the optical bus terminal (OBT)
  • The number of CPs that can be used is dependent on the performance range of the CPU and on the communications services used.
