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.

(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

Do not attempt to perform word writing to 
special relays.

Time-Out

“Check” is displayed 2 or 3 seconds 
before this error occurs when connecting 
V7 and PROFIBUS-DP in the RUN 
mode.

The setting for [Own Stat. No.] on V7 is 
discrepant with that for [Address] for [V7 
series] on the SIMATIC Manager.  Check 
and correct the setting.

A screen is displayed instantaneously (= 
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.
