NOTE
In FPWIN Pro, these errors are detected by the compiler. Therefore, they are not
critical.
Operation

PLC
A program with a syntax error has been written.
Stops
Change to PROG mode and correct the error.
Two or more operation results are output to the same relay. (This
error also occurs if the same timer/counter number is being used.)
Stops Change to PROG mode and correct the error.
This error is also detected during online editing. No changes will
be downloaded and operation will continue.
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 correct the error.
An instruction has been written which does not agree with system
register settings. For example, the timer/counter number setting in
Stops
a program does not agree with the timer/counter range setting.
Change to PROG mode and correct the error.
An instruction was written to the wrong program area (main
program area or subprogram area)
Stops Change to PROG mode and correct the error.
This error is also detected during online editing. No changes will
be downloaded and operation will continue.
The program stored in the PLC is too large to compile in the
program memory.
Stops
Change to PROG mode and correct the error.
In the program, high-level F and P instructions are triggered by
the same operation result. (While the execution condition is
TRUE, F instructions are executed in every scan. P instructions
are executed only once, at the leading edge of the execution
Stops
condition.)
Correct the program so that the high-level instructions executed in
every scan and at the leading edge are triggered separately.
There is an incorrect operand in an instruction which requires a
specific combination of operands (for example, the operands must
Stops
all be of a certain type).
Change to PROG mode and correct the error.
