Diagnostics alarms
A diagnostics alarm is output for each diagnostics event and the DIAG LED flashes on the
module. The diagnostics alarms can, for example, be read from the diagnostics buffer of the
CPU. You can evaluate the error codes with the user program

Error code
Meaning
1
Short-circuit of the actuator supply
H
4
Thermal overload of the I/O module
H
6
Impedance of actuator circuit too high
H
Wire break between the module and actua-
tor
Channel not connected (open)

The output value defined by the user pro-
H
gram is above the overrange.
8
The output value defined by the user pro-
H
gram is below the underrange.
9
Internal module error occurred
H
10
The module cannot evaluate parame-
H
ters for the channel.
Incorrect parameter assignment.
11
No or insufficient supply voltage L+
H
1F
Firmware update is currently in progress or
H
has been canceled.
The module does not output any process
or substitute values in this state.
Solution
Correct the process wiring
Reduce the ambient temperature, pay
attention to derating
Use a different actuator type or modify
the wiring, for example, using cables
with larger cross-section
Connect the cable
Deactivate the channel ("Output
type" parameter)
Deactivate diagnostics
Connect the channel
Correct the output value
Correct the output value
Replace the module
Correct the parameter assignment
Check supply voltage L+ on the
BaseUnit
Check BaseUnit type
Wait for firmware update
Restart the firmware update
