5–6 Module Status and Input Data
Publication 1771ĆUM127B-EN-P - December 2002
Output Status Data
Each output channel also has two words associated with it. The first
word contains low and high clamp, rate alarm, bad data, bad program
and bad calibration information for the processor. This is followed
by raw count data for that channel. If the module contains both input
and output channels, the output channel words would immediately
follow the header words.
