RIO Scanner Input Status and DCM/SLC Output Status
Using the Logical OR Bit
Whenever any of the status word bits (except the User Status Flag bit) are
set, the Logical OR bit is set. Using an Examine If Open (XIO) instruction
examining the Logical OR bit (word 0, bit 8 for SLC; word 0, bit 10 for
PLC-5) in your ladder logic, you could inhibit any outputs or processors
when this bit is set.
