Input Structure
You must use input tags to monitor module status. The table lists and defines
1756-HSC module input tags.
IMPORTANT
Some of the tags in the table below are followed by an ‘
x’
or a ‘y’. The ‘
x’ indicates the same tag information applies
for Channel 0 and Channel 1 on the 1756-HSC module.
The ‘y’ indicates the same tag information applies for the
four outputs (0…3) on the 1756-HSC module.
