Communicating with the GT2 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.
