Error details
• Transmission monitoring time was up.
• Failed to send though the system retried to
send for the maximum number of retries.
Receive wait time was up.
• 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.
Received the packet of the data length over 2048
bytes.
The data (digit) corresponding to the conversion
variables (variable number of data) was not
enough when data was received in the protocol
including the packet of conversion variables
(variable number of data).
The data corresponding to the conversion
variables (fixed number of data and variable
number of digits) was 0-bite or exceeded the
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.
The data corresponding to the conversion
variables exceeded the CPU capable range
when data was received in the protocol including
the packet of conversion variables.
Setting value in Data Length Storage Area, Data
Quantity Storage Area is out of range.
• Decimal point position for variable point is out
of range.
• Number of decimals is bigger than the one of
Number of digits per data.
Corrective action
Check whether the cable is connected.
• Check whether the cable is connected.
• Check whether any errors are found in the target
device.
• Check whether the sending data from the target
device has not been interrupted.
• Check whether any of data were lost because of
receive error.
• Check whether the send data (packet) from the
target device is correct.
• 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.
• Check the send data from external devices.
• If the data send from external devices exceed
2048 bytes, split it into several files and send
them separately.
• Check the send data from external devices.
• If protocol has been edited, check whether any
errors found for the digit setting value in the
packet format of the target device.
• Check the send data from external devices.
• If protocol has been edited, check whether any
errors found for the digit setting value in the
packet format of the target device.
• 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.
• 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.
• Check the maximum data length for Data Length
Storage Area, reset a value within the range.
• Check the maximum number of data for Data
Quantity Storage Area, reset a value within the
range.
• Check the decimal point position.
• Check the number of digits, set the decimal
point position to the one less than the number of
digits.
