The
I/O status LED
is ON when the
relay
is active, i.e. when the N/O contact is
closed and the N/C contact is open.
•
In the event of an error, the
I/O status LED
and the
module status LED
flash.
•
The meaning of the I/O status LED can be parameterized (TXM1.6R-M only):
Normal = green (default) / Alarm = Red / Service = Yellow.
For details, especially in relation to flashing pattern and errors: refer to the section "Dis-
play, operation and diagnostics" in the TX-I/O™ Engineering and installation guide [6].
