Warning; Warning List - Omron OMNUC G5 R88M-K series User Manual

11-2 Warning

This function outputs a warning signal and notifies the erroneous state such as overload before
an alarm starts to operate.
Set the warning output type to Warning Output Selection 1 (Pn440) and Waning Output Selection 2 (Pn441).
Refer to the description about the Warning Output Selection 1 (Pn440) and the Warning Output Selection
2 (Pn441) in Section 8-5 Interface Monitor Setting Parameter, and those about the Warning Mask Setting
(Pn638) and the Communications Control (Pn800) in "8-7 Special Parameters".
Precautions for Correct Use
 All warnings are retained. To reset the retained warnings, take the same procedures as resetting the usual
alarms.

*1. Set the Warning Output Selection 1 (Pn440) by the warning type to output to the Warning Output 1
(WARN1), and the Warning Output Selection 2 (Pn441) by the type to output to the Warning Output
2 (WARN2). If you set this to 0, all warning types are output.
*2. Each warning detection can be masked using the Warning Mask Setting (Pn638). The table shows
the corresponding bits.
When the bit is set to 1, the warning detection is masked.
