Noise rejection
Set the noise rejection. The available options appear depending on the scan interval setting.
If you are using the 24 VDC power supply on models with the 24 VDC/AC power supply (/P1
option), the noise rejection is fixed to 50Hz.
If the 12 VDC power supply (GP10-1J2W) is in use, the noise rejection is fixed to 50Hz.
For PID control modules, the noise rejection is fixed to Common.
Options Description
Auto The GX/GP automatically detects the power supply frequency and rejects
50 Hz noise for 50 Hz or 60 Hz noise for 60 Hz. However, noise is not
rejected if the scan interval is set to 1 ms, 2 ms, 5 ms, or 10 ms.
50Hz 50 Hz noise is rejected.
60Hz 60 Hz noise is rejected.
Common 50 Hz and 60 Hz noise is rejected simultaneously.
