%Q Configuration Values
3-46
This table shows the settings for both grids. These bits must be set during the first PLC
scan when the PLC transitions to run mode. %Q offset 2, 3 & 4 and 18, 19 & 20 set the
PSM for the field voltage and power configuration. Setting these values incorrectly will
yield invalid readings. All remaining bits may be changed during run mode to adapt to
changing field conditions.
