Input, Status, Output and Configuration Files for the Thermocouple/RTD/mV Module on the ControlNet Network 4-7
Idle State Behavior
The ControlNet Ex adapter can detect the state of the controlling
processor or scanner. Only 2 states can be detected:
– run mode,
– or program mode (idle).
When run mode is detected, the adapter copies the output data
received from the processor to the corresponding module output.
When program mode is detected, the adapter can be configured to:
•
leave the module output data in its last state (hold last state)
•
reset the module output data to zero (reset)
•
apply fault state data to the module output
Input Data Behavior upon Module Removal
I/O module input data sent by the adapter upon module removal is
configurable. The adapter can:
•
reset the module input data sent by the adapter to zero (reset)
•
leave the module input data sent by the adapter in the last state
before module removal (hold last state)
