Plant-wide communication by means of routing

Overview
In most automation systems, the programming device can only be operated via the bus cable
(subnet) connected directly to the automation system. On larger networked plants you must
connect the programming device to different bus cables (subnets) before you can go online to
a remote automation system.
Routing function
The routing function allows you to reach automation systems online across subnet boundaries
from a central point (Engineering Station) with the programming device or PC, in order, for
example, to download user programs or a hardware configuration or to perform test functions.
Requirements
The following conditions must be met for S7 routing:
● STEP 7 as of version 5.5 and SIMATIC PDM, i.e., SIMATIC PDM, are integrated.
● The communication-capable modules (CPUs or CPs) which establish gateways between
● All the automation devices or communications partners that can be reached in a plant
● The SIMATIC S7 station required is networked and can be reached via the network nodes.
● The last communication interface (CPU, CP) supports the "Dataset gateway" function.
● The modules are downloaded together with the configuration information, which contains
● The programming device or PC to which you want to establish an online connection via a

Checking the device integration

You can check in a project whether the required device descriptions are integrated for all
objects to be displayed in SIMATIC PDM.

the current "knowledge" on the complete network configuration of the project.
Reason: All the modules involved in the gateway must receive information on which subnets
can be reached over which routes (routing tables).

device.
