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.

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