Module bus master

There must only be one module bus master in the entire system. This must be the first station in the network. Other masters must be reconfigured as slaves if necessary.

In the delivery state, the devices have the presettings listed in the following table:

MDP90A/MDP92A power supply modules

Master

DC/DC converter module MDE90A

Slave

If you use the MDE90A DC/DC converter module in isolated operation, its presetting must be modified to module bus master using the MOVISUITE® engineering program. The module bus is configured using parameter group 8627 "Module bus".
