Modbus parameters
The following table shows the Modbus parameters in the M-
Max
TM
.
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.
PNU ID Access right Designation Value range FS
