Modbus parameters
The following table shows the Modbus parameters in the M-
Max

.
RUN Indicates the access right during operation (FWD or REV)
- = No parameter change possible,
/ = Parameter change possible.
ro/rw Indicates the access right via the fieldbus
ro = Read only possible,
rw = Read and write possible.
