- EtherNet/IP Network Unit CB-EP100 User’s Manual (LJ-V7000 Edition) -

EtherNet/IP requires that a connection must be opened from the scanner when cyclic
communication is started. There are various types of connections, and the type
usable by each device is defined in the EDS file.

The CB-EP100 can use the following connections:

Each connection's trigger timing is executed cyclically. The connection
type supports both point-to-point and multicast.

The details of each application type are as follows:

Exclusive Owner:

This connection allows simultaneous setting of both data
transmission from the scanner to the CB-EP100 and data
transmission from the CB-EP100 to the scanner. This setting is
made not only when the scanner monitors the adapter (CB-
EP100) data, but also when it issues control inputs and rewrites
the settings. etc. Multiple "Exclusive Owner" connections cannot
be opened to one adaptor (CB-EP100).

Input Only:

This connection allows only data transmission from the CB-
EP100 to the scanner. This setting is made when the scanner
only monitors adaptor (CB-EP100) data. Multiple scanners can
open an "Input Only" connection simultaneously to one adaptor
(CB-EP100).
(* To simultaneously open connections from multiple scanners,
set Connection Type to Multicast, and also set the same RPI
setting on each scanner.)
