Maintenance events
A maintenance event is generated for each maintenance required identified. The MT LED
lights up on the module.

Meaning / Cause
Missing or insufficient supply volt‐
age L+
Error is reported because the events
occur faster than they can be pro‐
cessed in the system
Internal module error has occurred
Errors in the redundancy parameters
sent to the module
Plausibility check between NC and
NO channel negative
Fault detected in the data block on
the carrier module during operation
An error of the memory block on the
terminal block was detected during
operation
Flutter error:
Signal changes too frequently within
the monitoring window
When the input signal stops fluttering
over three cycles of the monitoring
window, an outgoing diagnostics in‐
terrupt is triggered. The value state
of the current signal in the process
image is set to "valid".
Digital Input Module DI 16xNAMUR HA (6DL1131-6TH00-0PH1)
Remedy
● Check wiring of the supply
voltage L+ on the terminal
block
● Check the terminal block
type
Replace the module
● Check the parameter
assignment
● Check the slot and
terminal block
Check the process wiring, re‐
place encoder
Replace carrier module
Replace terminal block
● Check flutter monitoring
parameter assignment
● Check the process wiring,
replace encoder if
necessary
