2.5 2.5 Diagnosis of the EM 1 F-RO DC24V/5A AC24..230V/5A
Output status display
The output status display on the F-RO-module has the following behavior:
• Relay not activated: LED does not light up
• Relay is activated: LED lights up
• Relay not activated and relay contact welded: LED lights up
Causes of Errors and Corrective Measures
For diagnostic purposes you can evaluate the F-Systems S7 Distributed Safety output
"DIAG" des FB 216 "F_FDBACK," if you use this application block in your safety program for
the readback of relay contacts (refer to the manual
S7 Distributed Safety, Configuration and
Programming
).
