Corrected from:
p300 controller V3.9
Response of the new version:
Codes C424 to C426 can be accessed via the L_DMParameterAccess function block without error message. The values of these codes can be changed and saved fail-safe via the WebConfig.
What happens?
The L_DMParameterAccess function block from the L_PLCDataManagerAccess library outputs error number 28 via the dwErrorID output.
When does this behaviour occur?
When accessing the following p300 controller codes, the L_DMParameterAccess function block will output error number 28:
C424 (time until automatic dimout of display)
C425 (automatic dimout: brightness value)
C426 (brightness display)
Which products are affected?
p300 controller V3.8 and higher
Short-term measures:
None
Evaluation/recommendations:
p300 controller codes C424 to C426 cannot be accessed from the PLC program. Via the WebConfig the code values can be changed but not saved fail-safe.
