communication with BNR PLC using LOOKUP PROTOCOL

[Priyanku_BE]

Dear Sir,

I want to communicate with BNR PLC with PXI 8186RT controller. Is it possilbe to use NI Look Up protocol for communication?The PLC model is CP 340. Please help me out in this regard.

The PLC is having Ethernet & RS 232 interface.

Awaiting for the reply!

Hello,

Thanks for posting on the NI discussion forum.

I'm not sure I know what you mean by the NI Lookup Protocol. With your PXI Controller, is it running Windows XP?  Assuming that is the case, what development environment would you be using to interact with your PLC? LabVIEW?

If this is the case, then the most common way is by using an OPC server that has either been provided by your PLC manufacturer. Alternatively, we offer several OPC servers with our Industrial Automation OPC servers software.

To communicate from LabVIEW to an OPC server, you can either use datasocket or the LabVIEW Datalogging and Supervisory Control module.

Best regards,

Dear Sam,

Thanks for your valuable reply. To clarify you doubts, I herewith attached a document.We are using LabVIEW environment. The controller is

PXI 8186RT Real Time Controller.Can we use LabVIEW DSC for integrate the third paty PLC?

Looking at your document, Labview or an NI PAC might be able to do all of it. Do you have a website or info for the BNR plc??

Unfortunately, DSC cannot be installed on a real time PXI system

You can use it with the regular PXI controller, but the real time controller will not be able to run DSC.

As mentioned in my last post, if you are using the PXI controller in real time, you will not be able to set up an I/O server with DSC.  You could set it up on another PC connected to the PLC, then use shared variables to access this I/O server from the RT controller.  I'm not sure if this fits your plan correctly though.

Dear Brian,

Thanks for your valuable information. I am thinkng one more option. If I am going to use PAC Controller( cRIO 9012), can my job be done?

here some info about the BNR CP-340 PLC:

For 232, BNR PLC have DVFrame library which allows me to construct frame as per requirements.
So if u give me the frame details reqd by ur device then I can send and receive data using that frame.

We have used this 232 lib for many third party devices like drives, printers and weigh meters.


Ethernet library contains diff function blocks to establish network and communicate over TCP/IP and UDP.
This library is used for communication with our own PLCs. Right now I don't have any information/ project
where third party controller is configured and tested. If I get it, I will forward details of it.
But we can test directly with ur hardware.

for further info about the PLC, you can check the link below:

Awaiting for reply!!

The link you provided was to BNR Industrial Automation in Australia who obviously are a distributor for Mitsubishi PLCs.  But as far as I know Mitsubishi does not have a "CP-340" PLC.

Is there any chance that the PLC/CPU that you mean is from B&R (also commonly referred to as: B and R / B+R / Bernecker und Rainer Automation, etc.,etc.)?

They have a CP-340 CPU.

Apologies if I'm confusing things. Siemens has a CP340 communication processor, AutomationDirect has their old DL340 CPU etc. ... it can easily become a blur.

Maybe I am a little confused about what you are trying to do, but I think that all of the control for determining and removing the bad capsules can be done with a single cRIO system.  I don't understand exactly what the BNR PLC is doing that cannot be done with a well configured cRIO system.  You would just need a cRIO with a couple of 9205 modules and a 9422 and 9477 for the DIO communication.  As far as using an OPC server on the compact RIO system, like the other real time systems, you would not be able to install DSC and thus, use it to communicate with the PLC.

If I am misinterpreting anything, please let me know.  I will be glad to help you with any questions that you have.
