When using the Keyence KV series (EtherNet/IP communication scanner), the names of the connections
with the IV series will be “Monitor/External Input” and “Monitor Data”. The relationship of each connection
name is as described below.
1 : Monitor Data And External Input → Monitor/External input
2 : Monitor Data (Input Only)
→ Monitor data
y
The trigger timings of each connection are controlled by the cyclic communications; and both the point-
to-point and Multicast connection types are supported.
y
If you wish to open “Exclusive Owner” and “Input Only” connections simultaneously, set the connection
type to “Multicast” and match the RPI and the size.
y
The details of each application type are as described below.
[Exclusive Owner]
y
This connection allows you to configure the data transmission from the scanner to the IV series, and
vice versa.
y
This connection type is used when the scanner will not only monitor the data of the IV series but also
provide external input to the IV series.
y
It is not possible for multiple scanners to open "Exclusive Owner" connections for a single IV series
unit.
[Input Only]
y
This connection only allows you to configure the data transmission from the IV series to the scanner.
y
This connection is used when the scanner will only monitor the data of the IV series.
y
Multiple scanners can simultaneously open “Input Only” connections for a single IV series unit.
y
If connections will be opened simultaneously from multiple scanners, set the connection type to
“Multicast” and match the RPI and the size.
