(PLC). Check the network connection.

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

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.
