Module Status Bits
Communication; 0 = Not communicating, 1 = Communicating
Run; 0 = Not running, 1 = Running
Ready; 0 = Not ready, 1 = Ready
COM (Communication)
When this bit is set, the communication is started and the module is engaged in cyclic
data exchange with at least one of the connected slaves.
RUN (Run)
When this bit is set, the module is ready for communication. Otherwise, an initialization
error or incorrect parameterization has occurred. Further diagnostics is carried out with
the ProSoft fdt Configuration Manager configuration software.
RDY (Ready)
When this bit is set, the module is operational. The RDY bit should always be set by the
module. If this bit is not set, a system error has occurred and the communication
between controller and module is not possible.
