Chapter 4 – Programming
After the RMBA-01 Modbus Adapter module has been
mechanically and electrically installed according to the
instructions in Chapter 3, the master station and the
drive must be prepared for communication with the
module.
Please refer to the master station documentation for
information on configuring the system for
communication with the RMBA-01.
To establish communication between the RMBA-01 and
the Modbus controller, the parameters in group 52 must
be checked and adjusted where necessary (see the
drive manuals).
The detailed procedure of activating the module for the
control of the drive is described in the drive
documentation.
ABB drives can receive control information from
multiple sources including digital inputs, analogue
inputs, the drive control panel and a communication
module (e.g. RMBA-01). ABB drives allow the user to
separately determine the source for each type of control
information (Start, Stop, Direction, Reference, Fault
Reset, etc.). In order to give the fieldbus master station
the most complete control over the drive, the
communication module must be selected as source for
this information. See the user documentation of the
drive for information on the selection parameters.
