Special features of I/O types

Active bus

In redundancy mode, ibaBM-DP decides individually for each slave, on which bus the relevant information is sent.

The additional I/O type "Active bus" for the digital signals provides you with information about the bus via which the signals of a specific slave are currently being recorded by ibaBM-DP.

Further information on the I/O type "Active bus" can be found in chapterc Sniffer – Digital tab.

In the Slave column, you can define the slave for which you want to get information about the currently valid bus.

Status bus 0/1

Due to the way ibaBM-DP works, you do not need to select a bus system for the analog and digital signals in redundancy mode.

There is only one exception: the signal with the I/O type "status". In this case, the user needs to have the opportunity to address bus 0 or 1 for requesting the status.

As in redundancy mode there is no column for the bus system, here the I/O types "Status bus 0" and "Status bus 1" are being displayed.

Tip
	Define for each slave in the PROFIBUS system digital signals of the I/O type "Status" and "Active bus". Thus, you can evaluate the status of the slaves when analyzing the data later.
