Operation error [M8067(D8067)]
6708
Continues
operation
FROM/TO instruction error
This error occurs in the execution of operation.
•
Review the program, or check the contents of
the operands used in the applied instructions.
• Check whether the specified buffer memories
exist in the equipment.
• Check whether the extension cables are
correctly connected.
6709 Other (e.g. improper branching)
This error occurs in the execution of operation.
Review the program, or check the contents of the
operands used in the applied instructions.
Even if the syntax or circuit design is correct, an
operation error may still occur.
For example:
"T200Z" itself is not an error. But if Z had a value of
400, the timer T600 would be attempted to be
accessed. This would cause an operation error
since there is no T600 device available.
6710 Mismatch among parameters
This error occurs when the same device is used
within the source and destination in a shift
instruction, etc.
6730 Incorrect sampling time (T
S
) (T
S
≤
0)
<PID instruction is stopped.>
This error occurs in the parameter setting value or
operation data executing PID instruction.
Check the contents of the parameters.

6748
PID output upper limit set value < PID output lower
limit set value.
<Output upper limit value and output lower limit
value are incorrectly specified.

PID operation is
continued.>
Check whether the target setting contents are
correct.
6749
Abnormal PID input variation alarm set value or
output variation alarm set value (Set value < 0)
<Alarm output is not given.
→
PID operation is
continued.>
Check whether the target setting contents are
correct.
