Analog I/O Configuration
The following table shows the data ranges for 0 to 10V dc and 4 to 20 mA.
1762-IF2OF2 Input Data File
For each input module, slot x, words 0 and 1 contain the analog values of
the inputs. The module can be configured to use either raw/proportional
data or scaled-for-PID data. The input data file for each configuration is
shown below.
The bits are defined as follows:
•
Sx = General status bits for channels 0 and 1. This bit is set when an
error (over- or under-range) exists for that channel, or there is a
general module hardware error.
