3-4 Message Communication

3-26

Communicating with FD-MH Series

・ In EtherNet/IP (CIP), the method called "object modeling" is used to

express a device. The device is handled as a group of objects. Objects

abstractly express the configuration elements in the device. A class is a

group of objects expressing the configuration elements of the same

type. An instance actually expresses a specific object contained in a

class. Each instance in the class has the same attribute group, but each

uses a unique attribute value.

・ To execute a service for the DL-EP1, send a command from the scanner.

The DL-EP1 then returns the service execution results as a response. A

command requires a service, class ID (Class ID), instance ID (Instance

ID), and attribute ID (Attribute ID)

. When a parameter is written, the

command also requires a setting (service data).

* Some of the commands to be used may not require the above items.
