Idle State Behavior
The FLEX I/O HART module 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 I/O module 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
Chapter Summary
In this chapter you learned about input, output and configuration files for the
analog I/O modules on ControlNet or EtherNet networks.
