Error details
The external device IP address setting of the
dedicated instruction is incorrect.
The port number setting is incorrect.
The number of resends is specified incorrectly.
The arrival monitoring time setting is incorrect.
Sending messages by using the SP.SLMPSND
instruction has failed.
The CPU module was not able to receive a
response to the request.
The CPU module received a response with the
data length out of the range, which was sent by
the SP.SLMPSND instruction.
Setting value of protocol No. is out of range in
the control data of S(P).CPRTCL instruction.
• Protocol was executed while SM1332 is off.
• S(P).CPRTCL instruction was executed while
the protocol setting data was checking.
• S(P).CPRTCL instruction was executed while
error occurred in the protocol setting data.
• Protocol setting file has not been written to
valid drive.
• Protocol No. which was not registered to CPU
was specified at S(P).CPRTCL instruction
control data.
• S(P).CPRTCL instruction was executed
though the protocol setting data have not been
written to CPU.
Corrective action
Correct the IP address of the external device, and
execute the instruction again.
Check and correct the port number.
Check and correct the number of resends.
Set the arrival monitoring time within the allowable
range.
• Check the operation of the external device or
switching hub.
• The line may be congested with packets.
Resend data after a while.
• Check whether the cables are securely
connected.
• Check that there is no connection failure with the
switching hub.
• Execute a communication status test. If the test
completes with an error, take an action to correct
the error.
• Check the module for error by conducting the
module communication test.
• Check whether the IP address specified as
target is correct.
• Check and correct the response waiting time.
• Check the external device operation.
• Check whether the external device supports the
function executed.
• Correct the request data so that the response
data length will be within the specified range,
and execute the instruction again.
• If the same error code is displayed again even
after taking an action, please consult your local
Mitsubishi representative.
Check the setting value of protocol No.
• Execute the S(P).CPRTCL instruction after
SM1332 is turned on.
• Write the protocol setting data after turning the
CPU to STOP so that S(P).CPRTCL instruction
is not concurrently executed.
• Execute the S(P).CPRTCL instruction after
rewriting protocol setting data to CPU.
• If the same error is displayed again after
rewriting, the cause is a hardware failure of the
CPU module. Please consult your local
Mitsubishi representative.
• Check whether the specified protocol No. is
correct.
• Check whether the specified protocol No. has
been registered by the value for the with/without
protocol registration (SD1342 to SD1349).
• Execute the S(P).CPRTCL instruction again
after rewriting the protocol setting data.
