Diagnostics and Fault State
The ICoT FF provides two mechanisms of fault diagnostics, also compliant with FF specifications:
•
Fault State mechanism
•
Field Diagnostic mechanism
They can be configured to show important diagnostic and take safety actions when the ICoT is not
operating in normal mode.
The Fault State mechanism is described in Section 8.6 (Fault State Configuration) and the Field Diagnostic
mechanism is described in Section 9.1.2 (FF Field Diagnostics).
Another way to get diagnostic information from The ICoT is to use the local display messages, which can
also show some warnings or error messages. More details about these messages are described in Section
9.1.1 (Local Display Messages) and in the sections 11.6 and 11.7.
Whenever the ICoT is not operating in normal mode, presenting warnings, error messages or any
unexpected behavior, Chapter 9 (Maintenance and Repair) should be consulted for further information
about troubleshooting, diagnostics and FAQ.
