Input, Status, Output and Configuration Files for the Thermocouple/RTD/mV Module on the ControlNet Network 4-5
Adapter Status Word
The status word consists of:
•
I/O module fault bits – 1 status bit for each slot
Additionally, in the case of a PLC-5 controller, it adds:
•
node address changed – 1 bit (created by PLC-5 controller)
•
I/O status – 1 bit (created by PLC-5 controller)
Resulting in the following FLEX Ex adapter status word for a
PLC-5 controller.
As an example, in a PLC-5 system, the adapter status word bit
descriptions are shown in the following table.
