Disabling Error Log Entries of Non-fatal FPD(269) Errors
Normally when the FPD(269) Time Monitoring Function generates a non-fatal error, the error code and
the time that the error occurred are written to the Error Log Area (A100 through A199). It is possible to
set the PLC Setup so that the non-fatal errors generated by FAL(006) are not recorded in the Error Log.
Note Even though the error will not be recorded in the Error Log, the FAL Error Flag (402.15) will be turned ON,
the corresponding flag in the Executed FAL Number Flags (A360.01 to A391.15) will be turned ON, and the
error code will be written to A400.
Disable Error Log entries for FPD(269) time-monitoring errors when you want to record only the
system-generated errors. For example, this function is useful during debugging if the FPD(269) and
FAL(006) instructions are used in several applications and the Error Log is becoming full of these
errors.
• The following screen capture shows the PLC Setup setting from the CX-Programmer.
• The following table shows the PLC Setup setting from the Programming Console.

Note Even if PLC Setup word 129 bit 15 is set to 1 (Do not record FAL Errors in Error Log.), the following errors will
be recorded:
• Fatal errors generated by FALS(007)
• 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)
Setting Monitoring Time with the Teaching Function
If a word address is specified for T, the monitoring time can be set automatically with the teaching
function. Use the following procedure when a word address has been set for T.
1. Turn ON the FPD Teaching Bit (A598.00).
2. FPD(269) will measure the time from the point when the execution condition 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.
Note • FPD(269) can be used more than once in the program, but each instruction must have a unique register
(R) setting.
• The monitoring time is refreshed only when FPD(269) is executed. If the cycle time is longer than 100
ms, the monitoring time will not be refreshed normally and FPD(269) will not operate correctly because
the monitoring time is updated in units of 100 ms.
