Process Control System Pcs - Siemens SIMATIC PCS 7 Operating Manual

7. Check the default discrepancy time for redundant, fail-safe digital input modules.
8. Create a symbol for the lower I/O address and interconnect the channel driver with this
address.
If you are operating a HART device on a channel of a redundant module, you also need to
follow the steps outlined below:
1. In both modules, configure a "HART field device" on the relevant channel.
2. In the properties, select "On" or "Can be switched" under the HART_gate parameter and
activate the HART function of the relevant channel with the field device.
3. Double-click the HART field device of the module with the lower I/O address and
configure the field device in PDM.
4. When you save your settings in PDM, they will all be applied to both modules.
Note
You can find additional information on configuring redundant I/O modules in the "SIMATIC
