PCCC Manual

Hello Guys,

I am a Graduate Student, I am working on project with deals with PCCC object.

Anyone there who can help me out finding a manual or book explaining the PCCC object, I couldn't find a proper manual in Internet


Thanks in Advance

When you say PCCC Object are you referring to Allen Bradley protocol? If yes see the links below for some information but it may help if you told us more

Thank you for the Links.
Yes I am using Allen Bradley PLC 1766-L32BWAA
My situation is I am capturing the network traffic of this PLC when it is working
The Sample packet looks like this

Request Packet
6f001b00e9fefe83000000002a1200005818440200000000000000000a000200810001000191000a000f000700a22c00000000
Response packet:
6f004100e9fefe83000000002a120000581844020000000000000000000402008100010001910030004f0007005445535400000000000000000000000000003f0036050000000000000000000000000000000000000000499e

I think the highlighted hex bytes represents the PCCC object, Correct me if I am wrong

If I am right I need to find out what that PCCC command does, so I need the list of commands and functions used in PCCC

I dont have enough experience with the 'higher level' protocols comms... Mark, Archie or one of the other developers may be able to help

Good luck. The PCCC object is a vendor-specific object that is not clearly documented by Rockwell.

In the past, I found some interesting bits of info on this old automation blog:

This is the manual you are looking for :

http://literature.rockwellautomation.com/idc/groups/literature/documents/rm/1770-rm516_-en-p.pdf

Chapter 7 will give you what you are looking for.

In your sample packet, it is Command 0x0F and function 0xA2 which is covered on page 7-17

That manual covers DF1, so it shows 2 additional bytes at the beginning of the packet of Source and Destination. Some parts of the manual also refers to checksum byte(s) on the end. These bytes will not be in the Ethernet protocol, but the rest of the packet will be the same.

This is what I was looking for. Thank you @archie & @kherron

Thank you @geniusintraining for directing to the right person
