• S(P).CPRTCL instruction ended abnormally
because the cancel request was accepted
during protocol execution.
• S(P).CPRTCL instruction ended abnormally
because checking protocol setting data was
executed during S(P).CPRTCL instruction
execution.
• Check the canceled protocol in S(P).CPRTCL
instruction control data (Number of executions),
remove the cause of cancel operation.
• Write the protocol setting data after turning the
CPU to STOP so that S(P).CPRTCL instruction
is not concurrently executed.

The data (digit) corresponding to the conversion
variables (variable number of data) was not

including the packet of conversion variables
(variable number of data).
• Check the send data from external devices.
• If protocol has been edited, check whether any

maximum number of digits when data was
received in the protocol including the packet of
conversion variables (fixed number of data and
variable number of digits).

Data length does not match between the data
length shown by length and the one of
conversion variables in the received data from
external devices.
• Check the send data from external devices.
(1) Check whether the length value is correct.
(2) Check whether any of data were lost in
conversion variables.
• If protocol has been edited, check whether any
errors found for the conversion variables in the
packet format of the target device.

the packet of conversion variables.
• Check the send data from external devices.
• If protocol has been edited, check whether any
errors found for the conversion size setting in
the packet format of the target device.
(1) If the value exceeds the word size, change
the conversion size to the one of double
word.
(2) If the value exceeds the double word size,
change the elements to the non-conversion
variables.
