The setting is valid if the AO-C block is in the A2, B2, A1, or B1 slot. The loop
definition can be set for analog output.

Output scaling low and high limits
The setting is valid if the AO-C block is in the A2, B2, A1, or B1 slot. The output
scaling low and high limits can be set for analog output.
Item (bank) Display Description Initial value
Output scaling low limit
(ANALOG OUTPUT bank)
MENU > AnalogOutput
Output scaling low limit
−32000 to +32000
Either of the following units is used
depending on the output type.
% when the output type is MV
Same as AI (PV) (°C, etc.) if the output
type is PV, SP or deviation
0.0000
Output scaling high limit

The relationship between the output type and the output based on the output
scaling low and high limit settings is shown in the figure below.
