Input, Output and Configuration of the FLEX I/O HART Analog I/O Modules 29

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.
