8.9 Routing

Access from a PD/PC to stations in another subnetwork

As of STEP 7 V5.2 + Service Pack 1, you can reach S7 stations across

subnetwork boundaries with the PD/PC when using IM 151-7 CPU and the DP

master module, for example to load user programs or a hardware configuration or

to perform testing and diagnosis functions.

The routing function lets you connect a PD anywhere in the network and

establish a connection to any station that can be reached via the gateways.

The IM 151-7 CPU makes available 4 connections for routing PD functions. These

connections are additional to the S7 connections.

Note

If you use the your IM 151-7 CPU as an I slave, the routing function can only be

used when the DP interface is active.

Activate the Commissioning/Test Mode checkbox in the DP interface properties in

STEP 7.

Detailed information can be found in the Programming with STEP 7 manual or

directly in the STEP 7 Online Help.
