First connect ibaBM-PN to a free link of an ibaFOB-D card. In the I/O Manager, add a device module ibaBM-PN to the corresponding link.

Then add a module S7 Request.

In the General tab, set the parameter S2 Redundancy to "True". The orange colored icon of the Request module indicates the redundancy mode.

The configuration of the modules otherwise corresponds to the configuration in standard mode, see General module settings .
Connection settings

For transmitting the operand data to both CPUs of the SIMATIC S7-R/H, set up two different connections. ibaPDA switches between these connections depending on availability and requirements.

Configure both connections on the tabs Connection 0 and Connection 1. You can change the name of the tabs in the Connection name fields.

The other settings are identical to the settings for operation without redundancy mode, see Connection settings .

Note these special features:

  • The rack numbers for an H system are 0 or 1 for the both redundant CPUs.

  • Set the DB number, the PROFINET device slots and the CPU name for assigning an address book only once in the Connection 0 tab.
