PS69-DPM ♦ CompactLogix or MicroLogix Platform
PROFIBUS DPV1 Master
3.1.2 Input Array
Device Status Registers
The PS69-DPM module uses the first 4 bytes of the CPUs input area to transfer Device
Status Register information. The Device State Register contains information indicating the
modules communication status and command status. The CPUs input area mapping of this
information is shown below.


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.

RUN (Run)
When the RUN bit is set, the module is ready for communication. Otherwise an
initialization error or incorrect parameterization has occurred. Further diagnostic is
carried out with the PROSOFT.fdt (SYCON.net) configuration tool.

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.
