escription

Communication processors are used for connecting S****0 to the different bus systems / communication networks as well for point-to- point link. According to application case and module different protocols and different bus systems are available like PROFIBUS DP or Industrial Ethernet.

Point-to-point connection
Point-to-point link via communications processors (CPs) is an extremely powerful and low-cost alternative to bus systems.The advantage of point-to-point links over bus systems is especially pronounced when only a few (RS **5) devices are to be connected to the SIMATIC S7.
The CPs can also easily link third-party systems to the SIMATIC S7. Thanks to the great flexibility of the CPs, different physical transmission media, transmission rates or even customized transmission protocols can be implemented.
For each CP, there is a configuring package on CD with electronic manual, parameterization screen forms and standard function blocks for communication between the CPU and the CP.
The configuration data are stored in a system block and backed up in the CPU. When modules are replaced, the new module is therefore immediately ready for use.
The interface modules for the S****0 are available in three versions, each with one interface for the different physical transmission media.

Communication modules allow connection of the SIMATIC S****0 for instance to:

• SIMATIC S7 and SIMATIC S5 programmable controllers, and systems from many other manufacturers
• PCs, programming devices, hmi devices
• Field devices
• Robot controls
• Modems
• Scanners, bar code readers, etc.

• Reduced start-up times due to the easy configuration with STEP 7
• Reduced downtimes and service times in the event of a fault through LED displays
