Diagnostics messages and maintenance events

Diagnostics messages
A diagnostics message is generated for each detected diagnostics event. The DIAG LED on
the module flashes.
There is additionally a channel-specific display of the diagnostics through the corresponding
channel fault/channel status LEDs.
The diagnostics messages can, for example, be read out in the diagnostics buffer of the CPU.
Diagnostic messages are assigned either to one input on a channel-specific basis or to all
inputs as a module message. In the event of diagnostics messages that affect the entire
module, all channels are switched off. For diagnostics messages that relate to individual
channels, only the corresponding analog input is affected.

Assignment Meaning
Module Update of the firmware is being performed
or has been canceled. The module does not
perform any measurements during this time.
Module
● Ambient temperature is too high
● Short-circuit or overload of one or more
digital outputs/sensor supplies
Analog input ● Impedance of encoder circuitry is too
high
● Wire break between the module and
sensor
● Channel not connected (open)
Analog input
● The analog value is above the
overrange.
● Short-circuit of input to L+
Analog input The analog value is below the underrange.
Module
● Parameter assignment does not match
the terminal block used
● Incorrect parameter assignment
Module Missing or insufficient supply voltage L+

Remedy
● Restart firmware update
● Wait for firmware update
● Check wiring
● Eliminate the cause of the
excess temperature and
restart the module
● Use a different encoder
type or modify the wiring,
for example, using cables
with a larger cross-section
● Connect the cable
● Disable diagnostics
● Connect the encoder
contacts
Correct the module/encoder
tuning
Correct the module/encoder
tuning
● Correct the parameter
assignment
● Check terminal block
1
● Check wiring of the supply
voltage L+ on the terminal
block
● Check the terminal block
