If Alarm 1 is not provided or Alarm 1 timer unit is set to 0, the attribute becomes RO.
2
If Alarm 2 is not provided, the attribute becomes RO.
3
If Alarm 2 is not provided or Alarm 2 timer unit is set to 0, the attribute becomes RO.
4
These communication items, LA, HV and HW are not sent by Acknowledgement ACK from the
host computer. Send the polling sequence for these items separately (Example: EOT 00 LA ENQ).

The setting range is from
−
1999 to +9999 regardless of the position of the decimal point.
Note 1 Set the attribute to R/W (Read and Write) for OUT1 when OUT1 is used as transmission output.
Set the attribute to RO (Read only) for OUT1 when OUT1 is not used as transmission output.
