First connect ibaBM-DP to a free link of an ibaFOB-D card. Insert a device module ibaBM-DP on the respective link in the I/O Manager.
In the General tab, set the parameter Redundancy mode to "True". The orange colored icon of the device module indicates the redundancy mode.
You can operate the device in the 32Mbit Flex mode as well as in compatibility mode with 32Mbit.
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

The following modules cannot be used in redundancy mode:
These modules are deactivated automatically and cannot be activated manually, either. |
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.
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 PROFIBUS slave number and the CPU name for assigning an address book only once in the Connection 0 tab.
