Publication 1762-IN005C-EN-P - July 2013

The bits are defined as follows:

• SIx = General status bits for input channels 0 and 1.

SOx = General status bits for output 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.

• OIx = Over-range flag bits for input channels 0 and 1.

OOx = Over-range flag bits for output channels 0 and 1. These bits can be used in the

control program for error detection.

• UIx = Under-range flag bits for input channels 0 and 1.

UOx = Under-range flag bits for output channels 0 and 1. These bits can be used in the

control program for error detection.

Output Data File

For each module, slot x, words 0 and 1 contain the channel output data.
