I/O Configuration 1-5
Analog I/O Configuration
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.
•
Ox = Over-range flag bits for channels 0 and 1. These bits can be used
in the control program for error detection.
•
Ux = Under-range flag bits for channels 0 and 1. These bits can be
used in the control program for error detection.
