4-8 Input, Output and Configuration Files for the Analog I/O Modules on the ControlNet Network
Communication Fault Behavior
You can configure the response to a communication fault for
each I/O module in its system. Upon detection of a communication fault,
the module can:
• 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
Idle State Behavior
The FLEX Ex HART I/O module can detect the state of the controlling
controller 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 controller 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. Move to Chapter 5 to learn how to
calibrate your module.
