[Gordon Stewart <gord@xxxxxxxxxxxxx>]

Allen Bradley defines the following Service Codes for Logix5000 Data Access
in the Common Industrial Protocol.

0x03 - Multi-request service
0x0A - Get Attributes list service
0x4B - Execute PCCC Service
0x4C - CIP Read Data Service
0x4D - CIP Write Data Service
0x4E - RMW (Read/Modify/Write) Service
0x52 - CIP Read Data Fragmented Service
0x53 - CIP Write Data Fragmented Service

These Service codes are documented the the Logix5000 Data Access manual
Publication 1756-RM005A-EN-E-March 2000

Except the Execute PCCC and RMW services are documented in
Communicating with RA Products Using EtherNet/IP Explicit Messaging 
(Rev. 1.2), Appendix C

If anyone has the time or inclination it would be great to get these 
service codes added
to the CIP dissector.
