Action
This error occurs while the PLC is executing an operation.
Review the program, or check the contents of operands used in
instructions.
Even if the syntax or circuit design is correct, an operation error may
occur for the following reasons, for example.
Example:
"T200Z" itself is not an error. However, if Z is "100", "T200Z" means
"T300" which causes a device number error.
This error occurs while the PLC is executing an operation.
• Review the program, or check the contents of operands used in
instructions.
• Confirm that the specified buffer memory exists in the counterpart
equipment.
• Confirm that extension cables are connected correctly.
This error occurs while the PLC is executing an operation.
Review the program, or check the contents of operands used in
instructions.
Even if the syntax or circuit design is correct, an operation error may
occur for the following reason, for example.
Example:
"T200Z" itself is not an error. However, if Z is "100", "T200Z" means
"T300" which causes a device number error.
<The PLC stops PID operation.>
This data error occurs in the control parameter set value or during
PID instruction.
Check the contents of parameters.
<The PLC continues operation while regarding the operation data as
the maximum value.>
A data error has occurred in the control parameter set value or PID
operation.
Check the contents of parameters.
