Failure Diagnosis Instructions Section 3-28
Logic Diagnosis Function (C=800A)
Since the leftmost digit of C is 8 (bit address and message output mode) the
address of CIO 1000.00 (1000.03) is output to D302 through D304 in ASCII.
Setting the Monitoring Time with the Teaching Function
The monitoring time can be set automatically with the teaching function when
a word address has been specified for T.
To start the teaching function, turn ON A598.00 (the FPD Teaching Bit). While
A598.00 is ON, FPD(269) measures how long it takes for the diagnostic out-
put (CIO 200.00) to go ON after the execution condition (CIO 1000.00) goes
ON. If the measured time exceeds the monitoring time in T, the measured
time is multiplied by 1.5 and that value is stored in T as the new monitoring
time.
