• Non-fatal errors from the system
• Fatal errors from the system
• Non-fatal errors from the system generated intentionally with FAL(006) or
FPD(269)
• Fatal errors from the system generated intentionally with FALS(007)
If a word address is specified for T, the monitoring time can be set automati-
cally with the teaching function. Use the following procedure when a word
address has been set for T.
1. Turn ON the FPD Teaching Bit (A59800).
2. FPD(269) will measure the time from the point when the execution condi-
tion for FPD(269) goes ON until the diagnostic output is turned ON.
3. If the measured time exceeds the monitoring time setting, a setting 1.5
times the measured time will be stored in T.
