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.
