Note Reverse scaling, where the 0% scaling value is higher than the 100% scaling
value, is also supported.
Offset Compensation Offset compensation is used to compensate for error that occurs during scal-
ing. The offset amount is added to the scaled line before processing, as
shown in the following diagram. The offset (error) value can be input between
–28,000 and 28,000, but if underflow or overflow occurs in the scaled line, the
100% or 0% output will not be possible. The High Limit is 7FFE hex and the
Low Limit is 8000 hex.
Note The offset value can be set even when using default scaling.
Setting Procedure (Example: DeviceNet Configurator)
1,2,3... 1. In the Network Configuration Window for the Slice I/O Terminal, double-
click the icon of the Slice I/O Terminal that is to be set. Alternatively, right-
click the icon and select Parameters - Edit. The Edit Device Parameters
Window will be displayed.
2. Click the I/O Module Tab.
3. Click the Edit Button on the I/O Module Tab Page. The Edit Unit Parame-
ters Window will be displayed.
