Query Subnet ID
In the "Accessible via Network Transition" procedure, access is made from a
higher-level network to a lower-level network (subnet). When configuring networks,
STEP7 automatically assigns a subnet identification, the S7 subnet ID, to
differentiate the networks. This information is essential for online access to network
nodes in the subnets. The information may be queried in the SIMATIC Manager via
the object properties of the network.
The above window is displayed by selecting the relevant network icon and
selecting the object properties. The S7 subnet ID shown there can now be entered
in the properties for the access via networks.
