Diagnostics messages and maintenance events

Diagnostics messages
A diagnostics message is output for every recognized error. 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 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 message. For diagnostic messages which affect the entire module, all
channels are switched off. In the case of diagnostics messages that apply to single channels
only the corresponding analog input is affected.

Assignment Meaning
Channel Firmware being updated. The mod‐
ule does not carry out any measure‐
ments during this period.
Channel
● Impedance of encoder circuitry
is too high
● Wire break between the module
and sensor
● Channel not connected (open)
Channel
● The analog value lies above the
overrange
● Wire break
Channel The analog value lies below the un‐
derrange
Module
● Parameter assignment does not
match the terminal block used
● Incorrect parameter assignment
Module Missing or insufficient supply volt‐
age L+
Analog input module AI 16xTC/8xRTD 2-/3-/4-wire HA (6DL1134-6JH00-0PH1)
Solution
● Restart firmware update
● Wait for firmware update
● Use another type of encoder or
wiring, for example, use
conductors with a larger cross-
section
● Connect the cable
● Disable diagnostics
● Connect the encoder contacts
● Correct the module/encoder tuning
● Check the wiring
Correct the module/encoder tuning
● Correct the parameter assignment
● Check terminal block

● Check wiring of the supply voltage
L+ on the terminal block
● Check the terminal block type
