[Send Delay Time] (0 to 255) (Unit:
×1 msec)
Set a time delay in sending the response to the
PLC after receipt of data from the PLC. Normally
use the default setting (0).
PLC after receipt of data from the PLC. Normally
use the default setting (0).
[Total]
♦ (2 to 4)
Set the total number of the V7 series included in the multi-link 2 connection.
[Retry Cycle] (
×10)
Set the number of cycles before the master station sends an inquiry for restoration
to the slave station that has a communication problem (= system down). When a
slave station has a problem, it is temporarily removed from the communication
targets, and the master station sends an inquiry for restoration every number of
cycles specified for [Retry Cycle]. This setting does not affect the communication
speed if no problem is occurring; however, if there is any problem, it does affect the
communication speed.

[Baud Rate of Multi-Link]
♦ (4800, 9600, 19200, 38400, 57600, 76800, 115 kbps)
Set the baud rate used for communications between the V7 series. The setting
must be the same as other V7 series on the same communication line.

* For [Total] and [Baud Rate of Multi-Link], the same values must be set on all the V7
series that are connected in the same communication line.
3. Make the following setting when “1” is set for [Local Port] on the [Comm. Parameter]
dialog on the V7 series master station. Select [System Setting]
→ [Modular Jack].
Select [Multi-Link] for [Modular Jack 1] or [Modular Jack 2]. Connect the multi-link 2
master cable (V6-MLT) to the modular jack selected for [Multi-Link].

Communication Error
• When the master station has a communication error, the slave stations do not work and
the communication error “Time-out” is displayed. When the V7 series slave station has
a failure, a communication error occurs only on this station.
