To use the compatibility mode 32Mbit, set the rotary switches as follows: S1 = 1 and S2 = 0

With this setting, the device replaces the predecessor device ibaBM-DPM-S in existing installations and works with a fixed 32Mbit telegram on the FO side. A unidirectional FO connection is needed to the ibaPDA system. The configuration data is transmitted from ibaPDA to the device via an Ethernet connection. Sniffer function and active slaves can be used simultaneously.

In this mode, up to 512 analog (a total max. of 1984 bytes for analog values) and 512 digital values can be acquired. Up to 8 active slaves can be optionally assigned to Bus0/1.

The redundancy mode can be used in compatibility mode 32Mbit, see chapter Redundancy mode. The use of redundancy mode requires an additional license.

The device can be operated in 32Mbit mode also with an older ibaFOB-X card. The compatibility mode is also a good solution, if an existing ibaPDA system is to be extended, but no FO outputs are available or cannot be retrofitted.
