[?]: Data send and receive between two ControlLogix

[ramkamal_plc]

Shall i send one bit to other control Logix which one is connected in my same Control Logix through Network without using msg block?

any body knows abt this, pls give examble.

Hi,
Witch network do you use?

Why not use msg block ?

[neuhauser]

Set up produced / consumed tags in each processor to exchange data. Bit 0 can be used to verify data received.

Put each processor in the other's I/O list under the shared network. ( Use the complete path to the processor - backplane, enbt, gateways, etc.)

Set up arrays in each processor. One for shared data (Produced), one for received data (Consumed). These should be Dints for efficiency. The Consumed data will be the other processor's Produced data. (Array Tags must match)
Make any needed data conversions in logic.

Set the Update Time (RPI) in the arrays that the data needs to be updated. Don't set this any lower than needed.

When everything is set up the data will transfer in the background with no additional logic.

Produced / consumed tags are limited to 32 connections. This is the data links between processors not the actual amount of data.

If needed I can give screen shots of the set up.

If you use a msg instruction be sure to set the path in the correct format --- backplane, network adapter slot , IP or name, any gateways, backplane, controller slot.

Mr. neuhauser pls send me snapshots for understanding. thx for your valuable answer.


Mr. dehell i am using tcp/ip protocol.

Mr. larskbh i am already using msg block only.


thx for all.

Sorry for the delay. I'll put something together tonight.

Hi,
You will find a sample of 2 projects using Produced/consumed tag.

I don't know if projets are working, but i hope it will help you.
You can find more information in Rockwell sample projet.
Best regard

Here are some screen shots of a bare project with the steps on how to set up the I/O paths and the produced/consumed tags in RSLogix 5000. Be sure to add any gateways, etc. in the paths.
Just move the data in your logic to the produced tags.
