Example: Access of OPC UA clients to OPC UA servers via S7-1500 CPU with activated IP
Forwarding
OPC UA client and OPC UA server can also be connected to one another via an S7-1500
CPU, in which case the S7-1500 CPU operates as an IP Forwarder. This configuration
option allows for flexible expansion of existing systems.
