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

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

As on the redundant PROFIBUS, both bus systems 0 and 1 are operated in parallel, there are only settings for Redundant PROFIBUS on the General tab.

In redundancy mode, the following modules are available with Request-S7:

• S7 Request

• S7 Request Decoder

• Dig512 S7 request

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

Connection settings

For transmitting the operand data to both CPUs of the SIMATIC S7-400H, set up two different connections. ibaPDA switches between these connections depending on availability and requirements.

The connection settings are identical to the Request-S7 for ibaBM-DP in redundancy mode (see chapter Configuration and engineering SIMATIC S7-300, S7-400 and WinAC).
