Chapter 3: Configuring the 2085sc-IF16 Using CCW
The structure definition for each 'Ch n Status' in the Input Assembly table is
described below.
Each channel status struct is only one byte. Two channel status structs are stored
in each input word. The low byte (bits 0-7) of each channel status word is for the
first channel; the high byte (bits 8-15) is for the second channel. For example,
"Input 23" word bits 0-7 represent channel 14 and bits 8–15 represent channel 15.
Unused bits are 0.
Description
0: No Channel Fault
1: Channel Fault
This bit is set when the channel has an open circuit condition,
data error, or under/over range condition. It is also set if the
Module Power Up bit is set or the Module General Fault bit is
set.
0: No Data Error
1: Data Error
This bit is set for an enabled channel that is not receiving a
reading from the ADC. When set, the respective channel data
value remains the same as the previous sample.
