I have established Produced/Consumed CIP Messages between these two PLCs
To B&R_Dints[124] and From B&R_Dints[125]

I require to set up another 100 Dint array to read from the B&R PLC for information data every 15 minutes
I am trying to get a explicit message working

I am using a CIP Data Table Read
and the responce I get is:
Class or Instance not supported

I can not get this to work
Has anyone else been able to get this working?

Equipment:
ControlLogix version16
ENBT/A Ethernet Module

B&R X20 CP1485

Cheers

"Class or Instance not supported" message comes from B&R and it means that they don't understand class or instance that you put in your CIP message.

Do you have example from B&R?
if you do then post it here along with your program and someone will take a look.

I have established the Implicit Messaging between the PLCs
Currently we have working:
BR_to_INSTLGX[124], DINT
INSTLGX_to_BR[125], DINT
These are defined in a Generic Ethernet Module in the AB RSLogix5K IO Tree
And in the eipcfg Data Object in the B&R Automation Studio

I would like to execute an explicit message to get an additional array of 100 DINTS about every 15 minutes

I have tried executing a “CIP Data Table Read” message
The message generates an error stating “Class or Instance not supported”
Error Code 16#0005

So I believe I need to use a Generic CIP message with Custom settings
I don't know the Class or Instance values I should be using. I have requested information from the support People of B&R PLCs


My question is, what the correct way to set up an Explicit Message from an AB ControlLogix to third party device

Equipment used for test:
1756-L63 ControlLogix Version 16.20 slot 3
1756-ENBT/A Ethernet Bridge Version 4.3 slot 6 IP 192.168.1.196

B&R X20 CP1485
IF2 IP 192.186.1.195
Sysconf V2.94

The Eipcfg file in the B&R reads
"#OWNIP=192.168.1.195"
"#OWNINTERFACE=IF2"
"#STATION=INSTLOGIX"
"#STATIONIP=192.168.1.196"
"#STATIONSTATUS=udTestStationStatus"
"#CONNAME=TESTLOGIX"
"#CONDIR=BOTH"
"#CONRPI=100"
"#INPUTASSEMBLY=AssemIn1"
"logi:BR_to_INSTLGX, DINT, 125"
"#OUTPUTASSEMBLY=AssemOut1"
"logi:INSTLGX_to_BR, DINT, 124"
"#ASSEMBLY=expMES"
"logi:TOPPROF1, DINT"

Any help on this would be appreciated

So you are implicitly communicating with Assembly 1? Your trying to write data to assembly 2 now? How do you have the B&R configured in the Controllogix? It may give a clue of how to setup the additional ones

SWAG

Message Type: CIP Generic
Service Type: Get Attribute Single
Instance 9
Class 4
Attribute 3
Destination DINT[125]

Don't forget to set your path

The Implicit messaging is working after I built a generic ethernet module in the IO Tree
This gives me an array of Dints To and From the B&R
I have tested writing data into the AB PLC and in the B&R PLC and the data is transferred across to each PLC as expected
No code was written in the AB PLC to get this working, just having the module defined worked.

I have tried getting a Generic CIP Message to read the tag "TOPPROF1"
I have just tried using
Service=0x01 (GetAttribAll),
Class=0x01 (Identity)
Instance=0x01 for first instance
As Generic attributes
The message gets done but the values in the destination don’t match source and if I change the values in the source the values in the destination remain the same. I believe I am reading data from the IP port settings or something? changing the class I then get different data in the destination but again it is static data and doesn't corresponds to the data entered into the source.

Class 1, Instance 1, Attribute 1 is "Get Device Identity" object.
Look at the data returned as "ASCII" and you will see device description

Did you try TWControls parameters?

Yes I tried TW parameters

The Messsage errored with:
Class or Instance not supported
Error 16#0005

IF Assembly 1 is 101 then looks like the Instance should be 103 to get to Assembly 2


Rereading, I'm a little confuse. Which way are you trying to read? B&R to Controllogix or Controllogix to B&R?

I have succsess

The CIP Generic message is now working

Message Type CIP Generic
Service Type Get Attribute Single
Class 4
Instance 103
Attribute 3
Destination Test_Array

I now have two Explicit Messages getting Dint[100] each, every second
And the Dint[124] and a Dint[125] communicatng through the defined Ethernet Module in IO tree at 100ms

On the second Expilict message the Instance is set as 104

Thanks for all the Tips
Cheers

I don't know how far you plan on taking this but be aware that there are limitation to how many messages you can execute at a time. I would suggest staggering them. Since you are executing two messages every second, make it execute message 1, half second later execute message 2, half second later message 1...
