The ibaBM-DDCS device is a bus monitor for the DDCS communication bus from ABB.

The device can be used for capturing of signals and their transmission to an ibaPDA system in order to record data continuously or triggered by event.

The purpose of this device is:

• to be able to locate errors quickly

• to be able to assess the quality of the closed-loop control and derive conclusions about the status of the machine

• to optimize the drive.

The ibaBM-DDCS enables free and reactionless access to the drive’s parameter and to the communication telegrams between drive and controller. The desired data is selected with the I/O Manager of the ibaPDA software.

The communication between ibaPDA and ibaBM-DDCS is handled by the bidirectional iba fiber optic protocol 32Mbit Flex, which requires an I/O card of the ibaFOB-D generation, e. g. ibaFOB-2io-D. The sampling rate can be up to 40 kHz, whereby up to 4060 Byte can be transmitted over the fiber optics to the ibaPDA computer.

Fields of application

The device is intended for:

• the permanent connection of an ibaPDA system

• the connection of an ibaPDA system only when needed (errors/problems)

• the temporary connection of a mobile computer or notebook

The ibaPDA recording software is optimized for large amounts of data. Depending on the ibaPDA license and computer capacity, any number of analog and/or digital signals can be captured, visualized and recorded. Measurements with a sampling time of down to 25 µs are possible.

Furthermore, iba has other modules, connections and software components for connecting a variety of PLC systems, which can be connected in parallel to the ibaBM‑DDCS device.
