Message Communication
This section describes the message communication functions and how to use them.
„ What is Message communication (Explicit messaging)?
Message communication is a function that performs communication by issuing
commands using the objects and services (Service Codes) prepared for each
EtherNet/IP device. Message communication is used for applications which do not
require the punctuality of cyclic communication, such as reading and writing adaptor
settings.
The objects and service codes which can be used with message communication
include those which are specified as a standard and those which are unique to the
device. You can use objects and services unique to the CB-EP100 to read and write
setting values and to perform operations such as control input, read measurement
values, judgment status and other operations.
The CB-EP100 message communication function supports CIP-defined
UCMM (unconnected) and Class 3 (connected) message communication.
