1. Before Connecting to PLC
1-11
Choose the action to be taken against communication errors.
[Comm. Err. Handling]
Set error handling routine in the case that a communication error between the V7 series
and the PLC occurs.
[Stop]
If any communication error has arisen, the communications are stopped.
When restoring, use the Retry switch (found on the error screen of the V7
series).
[Continuous]
If any communication error has arisen, it is indicated at the top left corner
on the V7 screen. The V7 series conducts polling of the PLC, and if OK,
the error state is automatically reset.
[Time-out Time] (0 to 999) (Unit:
×
10 msec)
Specify a time for monitoring the receiving of a response from the PLC. If no response is
received within the specified time, a retrial is attempted.
[Retrials] (1 to 255)
Specify the number of retrial times. When the problem persists even after as many retrials
as specified, the system will start the error handling routine.

When processing characters, choose
either option for arranging 1st/2nd bytes
in one word.
[Code] (DEC/BCD)
Choose the code for entering numerical
data.
For some numerical data, such as those for data displays or data sampling in the sampling
mode, this setting is not applied because BCD or DEC should be chosen for [Input Format].
[Read Area] [Write Area]
For more information, refer to “System Memory” (page 1-12).
[
Read/Write Area GD-80 Compatible]
When converting screen data files created on GD-80 into those of the V7 series, this option is
automatically checked.
When this option is checked, GD-80 compatibility is supported by securing 2 words each for
[Read Area] and [Write Area] in the same format as GD-80. For more information, refer to the
GD-80 User’s Manual.
[
Use Ethernet]
When using Ethernet communications, check this option.
For details, refer to “9. Ethernet” in “Chapter 5, Connections” in the separate V7 Hardware
Specifications.
Supplemental Information:
Polling
“Polling” means to constantly monitor and check the state of the other station.
