Function
When an error occurs, the Error Log
Pointer is incremented by 1 to indicate
the location where the next error record
will be recorded as an offset from the
beginning of the Error Log Area (A100
to A199).
Note 1 The data will be unstable if the
capacitor becomes
discharged.
2 The Error Log Pointer can be
cleared to 00 by turning
A500.14 (the Error Log Reset
Bit) ON.
3 When the Error Log Pointer
has reached 14 hex (20 deci-
mal), the next record is stored
in A195 to A199 when the next
error occurs.
The manufacturing lot number is stored
in 6 digits hexadecimal. X, Y, and Z in
the lot number are converted to 10, 11,
and 12, respectively.
Examples:
Lot number 01805
A310 = 0801, A311 = 0005
Lot number 30Y05
A310 =1130, A311 = 0005
ON when the Option Board is removed
while the power is being supplied. CPU
Unit operation will continue and the
ERR/ALM indicator will flash.
Note OFF when the error has been
cleared.
ON when a built-in analog I/O error
occurs and stops the operation of
built-in analog I/O. CPU Unit operation
will continue and the ERR/ALM indica-
tor will flash. OFF when the error has
been cleared.
ON when writing to the built-in
EEPROM backup memory fails. CPU
Unit operation will continue and the
ERR/ALM indicator will flash.
Note OFF when the error has been
cleared.
