FP0 Hardware 11.3 Error Codes
11-11Matsushita Electric Works (Europe) AG
The operation of the controller might stop depending on the
content of error and the system resistor setting.
The error codes will be stored in the special data resister DT9000.
In the case of operation error, the error address will be stored in
the DT9017 and DT9018.
Clearing the self-diagnostic error
See page 11-3.
Errors can also be cleared by turning OFF an ON the power.
However, memory contents not stored with the hold type data will
also be cleared.
The error can also be cleared depending on the self-diagnostic
error set instruction F148(ERR).
Steps to take for self-diagnostic error
The steps to be taken will differ depending on the error contents. For more details, use
the error code obtained above and see page 11-12.
11.3.2 Syntax Check Error Codes
Error

Name of error Operation
status
Description and steps to take
E1 Syntax error Stops
A program with a syntax error has been written.
(SYNTAX)
Change to PROG. mode and correct the error.
E2 Duplicated
output error
(DUP USE)
Stops Two or more OT(Out) instructions and KP(Keep) instructions are
programmed using the same relay.
This error also occurs if you have the same timer/counter numbers.
Correct the program so that one relay is not used for two or more
OT(Out) instructions and KP(Keep) instructions. Or, set the double
output to “K1: enable” in system register 20.
E3 Not paired error
(PAIR)
Stops For instructions which must be used in a pair such as jump (JP and
LBL), one instruction is either missing or in an incorrect position.
Change to PROG. mode and enter the two instructions which must
be used in a pair in the correct positions.
E4 System register
parameter error
(Mismatch)
Stops An instruction has been written which does not agree with system
register settings. For example, the number specification in a program
does not agree with the timer/counter range setting.
Change to PROG. mode, check the system register settings, and
adjust so that the settings and the program agree.
E5 Program area
error (PRG
AREA)
Stops An instruction which must be written to a specific area (main program
area or subprogram area) has been written to a different area (for
example, a subroutine SUB to RET is placed before an ED
instruction).
Change to PROG. mode and enter the instruction into the correct
area.
