Failure Diagnosis Instructions
Section 3-30
Bit Address Output (C=0
@@@
)
When the leftmost digit of C is set to 0, the 8-digit hexadecimal PLC memory
address of the input bit is output to R+2 and R+3. R contains two flags which
indicate whether an input bit has been found and whether it is used in a nor-
mally open or normally closed input condition.
Bit Address and Message Output (C=8
@@@
)
When the leftmost digit of C is set to 8, the ASCII address of the input bit is
output to R+2 to R+4. R contains two flags which indicate whether an input bit
has been found and whether it is used in a normally open or normally closed
input condition.
Register words R+2 to R+4 indicate the address of the input which prevented
the diagnostic output from being turned ON. The bit address is output to these
words in ASCII. The following table shows the ASCII representations for each
area.
