Remarks
1) In principle, all communication channels can be combined with each other. However, the
subordinate communication drivers can lead to limitations.
When the SIMATIC S7 Protocol Suite is used, a maximum of 64 S7 connections can be
operated. A typical configuration contains 60 S7 connections, for example.
Examples:
● 8 S7 connections via "MPI" and 52 S7 connections via "Industrial Ethernet TCP/IP"
or
●
60 S7 connections via "Industrial Ethernet TCP/IP"
2) COM1/COM2 or internal software interfaces for SIMATIC S7 Protocol Suite communication
"Soft-PLC" and "Slot-PLC" as well as DCOM for OPC.
3) In the case of Soft-Net, communication runs on the PC processor. In the case of Hard-Net,
the communication card has its own microprocessor and relieves the PC processor during
communication.
