Which connection resources are occupied in the S7-400 CPU for communication connections and services of the Industrial Ethernet CP?
One connection resource is required in the S7-400 CPU for each of the following communication connections of the Industrial Ethernet CP:
|PG communication via S7 server||
|System connection via S7 server||
If the SEND / RECEIVE, FTP and Web diagnostics services are used simultaneously in the Industrial Ethernet, 3 connection resources of the S7-400 CPU are occupied.
An Industrial Ethernet CP occupies a maximum of 3 connection resources in the S7-400 CPU, i.e. maximum one connection resource for:
- PG communication via S7 server (TSAP=0x01)
- System connection via S7 server (TSAP=0x03)
- System connection SEND/RECEIVE (TSAP=0x0F)
