Time Monitoring:
Monitors whether output C goes ON within 10 seconds after input A. If C doesn't go ON within 10
seconds, a failure is detected and the Carry Flag is turned ON. The Carry Flag executes the error-
processing block. Also, an FAL error (non-fatal error) with FAL number 004 is generated.
Logic Diagnosis:
FPD(269) determines which input bit in block B is preventing output C from going ON. That bit
address is output to D1000.

A400 When an error occurs, its error code is stored in A400.
A402.15 ON when FAL(006) is executed.
A401.06 ON when FALS(007) is executed.
A360 to The corresponding flag is turned ON when an FAL(006) or FALS(007)
A391 error occurs.
A100 to The Error Log Area contains information on the most recent 20 errors.
A199
A300 When an error occurs, the Error Log Pointer is incremented by 1 to indi-
cate where the next error record will be recorded as an offset from the
beginning of the Error Log Area (A100).
A500.14 Turn this bit ON to reset the Error Log Pointer (A300) to 00.
A598.00 Turn this bit ON when you want the monitoring time to be set automati-
cally when FPD(269) is executed.
