Error Message Contents Solution
I/F Board Err The I/F unit for OPCN-1 has an error. Contact your local distributor.
Stat. No. out of range The port number set by a switch is not
within the setting range (1 to 127).
Specify the port number within the setting
range.
Network Link Error Cannot connect to the master station in
the network.
Check the condition of the master station
(PLC). Check the network connection.
Network I/O Access Err MONITOUCH is about to access
exceeding the set number of input/output
words.
Check the memory for the network I/O in
the screen data file.
Waiting for Reply 1) Less than “Max_int” time
(communication monitoring time for
salve station) set on the PLC for
OPCN-1 communications
2) Timeout on the V-SFT editor
(The timeout time can be set from
[System Setting] → [Comm.
Parameter] on the V-SFT editor.)
This error is indicated when the above 1)
and 2) are present.
When the “Max_int” time is too long
(infinite, for example) on the PLC, it is not
possible to know whether or not the
response from the PLC is correctly
made. This error message disappears
when a response from the PLC is
received within the “Max_int” time.

Word writing to a special relay (M9000
and later) is attempted.
(Notes: Only bit writing is possible for
special relays when connecting with

Do not attempt to perform word writing to
special relays.

communications performed) before this
error occurs when connecting V7 and
PROFIBUS-DP in the RUN mode.
The DB address set on the V7 screen
may not exist on the PLC (memory over).
Check the setting.
