System interfaces for SIMATIC S7 and PG-PC

System interface for S7

  • Interface to S7 via communications modules
  • Autonomous handling of protocols for data and/or process communication
  • CPU load reduction
 
     
Example: PROFIBUS DP configuration for SIMATIC S5/S7 and PG/PC
 
Example: PROFIBUS FMS configuration for SIMATIC S5/S7 and PG/PC  

PG/PC interface

PGs/PCs are connected by means of interface cards, of which there are two versions:

  • PC card with its own microprocessor
    The recommended solution for:
    – PC-based control systems (SoftControl, PLCs, numerical control, robot control)
    – Process control systems
    – HMI systems
    – PROFIBUS systems with more than 8 nodes
    – Use of multiple protocols
    – Use of multiple CPs in one computer
 
   
Example: PC cards
