Technical Data for connection to Allen Bradley Logix 5000
Series PLC on EtherNet/IP
The technical data that need to be considered while connecting to Allen Bradley
Logix 5000 PLC's on EtherNet/IP are:
• EtherNet/IP supports three Class 1 connection and three Class 3 tag per Allen
Bradley Logix 5000 series PLC. The CI873 supports three Class 3 tags with
100ms cycle time.
• The data transfer, using the Class 3 connection, will be slower than the Class 1
connection.
• The Class 3 connection is not supported for any EtherNet/IP devices except
Allen Bradley Logix 5000 series PLC. The CI873 uses tag based Class 3 to
write data to it.
• The maximum number of bytes supported for Class 1 read tag is 496 and for
Class 3 write tag is 432.
Technical data for S200 IO modules
The technical data that need to be considered while configuring S200 IO Modules
are:
• Maximum of 30 200-AENTR Adapters can be added under CI873.
• Each S200 IO module will consume one CIP connection.
CI873 supports tag based CIP communication with Allen Bradley Logix 5000
series controllers, catalog numbers for the same are mentioned below: 
-1756 ControlLogix, 1756 GuardLogix, 1768 CompactLogix, 
1769 CompactLogix, 1789 SoftLogix.
CI873 does not support communication with MicroLogix series controllers as it
does not support Tag based communication, instead use PCCC commands
encapsulated in a EtherNet/IP message.
