$Pn: 99
The update timing for the link down information stored in $Pn: 010 to 025 is set here.
0: Always updated with the latest information
Other than 0: Only updated when a communication error occurs
•
Example:
An error has occurred at station No. 18. 2nd bit of $Pn: 11 is set (ON).
After resetting communications
- If $Pn: 99 = 0, the link down information is updated.
- If $Pn: 99 = other than 0, the link down information is not updated.
$Pn: 100 to 355
The results of communication with each station are stored here. The status codes are shown below.
Errors other than the above are stored as shown below.

Error Detail Solution
Time-out
Although a request to send is given, no answer is
returned within the specified time.
Implement solutions 1, 2, and 3.
Check code The check code of the response is incorrect. Implement solutions 1 and 3.
Data error The code of the received data is invalid. Implement solutions 1, 2, and 3.
Error code received An error occurs on the connected device. Refer to the instruction manual for the PLC.
Buffer full The S8 buffer is full. Contact your local distributor.
Parity An error occurred in parity check. Implement solutions 2 and 3.
Overrun
After one character is received, the next character is
received before internal processing is completed.
Implement solutions 1 and 3.
Framing Although the stop bit must be “1”, it is detected as “0”. Implement solutions 1, 2, and 3.
Break detection The connected device’s SD remains at the low level.
Examine the connection with the connected
device’s SD/RD.
