Configure Your Controller for EtherNet/IP Communication
For input assemblies, the CIP message codes include the following:
•
Service: 0xE - Get Single Attribute
•
Class: 4
•
Instance: 100 or 101 (input 1 or input 2 respectively)
•
Attribute: 3
For output assemblies, the CIP message codes include the following:
•
Service: 0x10 - Set Single Attribute
•
Class: 4
•
Instance: 102 or 103 (output 1 or output 2 respectively)
•
Attribute: 3
This example shows a CIP message code that accesses Input Assembly 1 of the
SmartGuard controller.
The member field is always defined as 1.
1.
From the Service Code pull-down menu, choose the CIP service code.
2.
Type the class, instance, and attributes codes for the tag in order to access
the correct target I/O assemblies in the SmartGuard controller.
The maximum size of a single member tag defined in the PanelView terminal is a
DINT (4 bytes). A target I/O assembly in the SmartGuard controller can be as
large as 16 bytes. In order to access all of the bytes in the target assembly, you may
need to create up to 4 DINT tags, where an Offset is defined for each tag to
correspond with the target bytes of that tag.
