1187 RTC Trim
A trim value that may be used to speed up or slow down the Real Time Clock on the IO option. A positive trim value will cause the
RTC to run faster, an negative value causes the RTC to run slower. Refer to the AC30V General Purpose I/O Option manual for
more details.
Once programmed, the RTC trim affects the operation of the RTC both in battery backed up mode and normal running mode.
Analog input Scale and Offset
The input signal is converted to a percentage of the hardware range, that is -10V…10V is represented as -100 to 100%. The Offset is then added
to this input and the result of this is multiplied by the Scale factor. The result is presented in the Value parameter.
