Siemens SIMATIC 6DL1131-6DF00-0PK0 - Diagnostics Messages and Maintenance Events

A.4 Diagnostics messages and maintenance events [ID: 91008185867]
Diagnostics messages
A diagnostics message is generated for every fault identified. The DIAG LED on the module
flashes.
There is additionally a channel-specific display of the diagnostics through the corresponding
channel fault LEDs
The diagnostic messages can, for example, be read from the diagnostic buffer of the CPU.
Diagnostic messages are either assigned to an input for specific channels or assigned to all
inputs as a module alarm. For diagnostic messages which affect the entire module, all channels
are switched off. For diagnostic messages which refer to individual channels, only the
corresponding digital input is affected.

Digital input Impedance of encoder circuitry is too
high
Use a different encoder type or
modify the wiring, for example,
using cables with a larger cross-
section
Wire break between the module and
sensor
Connect the cable
Channel not connected (open)
● Disable diagnostics
● Connect encoder contacts
with a 25 kΩ to 45 kΩ resistor.
