Behavior of the Fail-Safe I/O Module in the Event of Module Failure
The following events occur following a serious internal fault in the fail-safe I/O
module causing fail-safe I/O module failure:
• The connection to PROFIBUS DP is interrupted and the fail-safe inputs are
passivated
• Diagnostic information is not sent by the fail-safe I/O module and the standard
diagnostic message "module fault" is signaled.
• The SF LED of the fail-safe I/O module lights up.
Specific Information about Diagnostic Functions
All module-specific diagnostic functions, possible causes and remedies are
described in Section 8.2.
This chapter also describes which status and diagnostic functions can be displayed
by LEDs on the front panel of the fail-safe I/O module.
Reading out Diagnostic Functions
You can display the cause of an/a error/fault in the module diagnostics of STEP 7
(see STEP 7 Online Help).
You can read out diagnostic functions (slave diagnostics) by means of SFC 13 in
the standard user program (see System and Standard Functions reference
manual).
