The following table shows how to specify error codes and error details in S
and S+1.
Error name
Flash Memory Error 00F1 hex
Interrupt Task Error 008B hex
PLC Setup Error 009B hex
Built-in Analog I/O 008A hex
Error
CPU Bus Unit Error 0200 hex
Special I/O Unit 0300 hex
Error
Option Board Error 00D0 hex
Battery Error 00F7 hex
Disabling Error Log Entries of User-defined Errors)
Normally when FAL(006) generates a user-defined 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 user-defined errors
generated by FAL(006) are not recorded in the Error Log.
Even though the error will not be recorded in the Error Log, the FAL Error Flag
(A402.15) 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 user-defined FAL(006) errors when you want to
record only the system-generated errors. For example, this function is useful
during debugging if the FAL(006) instructions are used in several applications
and the Error Log is becoming full of user-defined FAL(006) errors. The follow-
ing table shows the PLC Setup setting:
Item

Default setting
Times that PLC Setup set-
ting is read
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)

• Bit 15 ON: Interrupt task execution conflicted
with Special I/O Unit refreshing
Bits 00 to 14: Unit number of Special I/O Unit
with refreshing conflict

CPU Bus Unit's unit number:
0000 to 000F hex
Special I/O Unit's unit number:0000 to 005F hex
or 00FF hex (unit number undetermined)
Option slot number: 0001 or 0002 hex
