Studio 5000 Modbus TCP Server Allen Bradley Controllogix Compactlogix

We are going to setup a Modbus TCP Server in Studio 5000 for the Allen Bradley Controllogix and Compactlogix PLC using Rockwell Automation's Modbus TCP Client Add On Instruction AOI sample program.
I was surprised to find this add on instruction that requires no third party devices to communicate between Allen Bradley PLCs and Modbus TCP clients.

Hi Tim. Great video. I recently setup my Micro820 as a Modbus TCP Server via CCW and have VTScada picking up the data the way I need it. A question I have is if there is a way to continue to send data to a remote storage rather than local storage for keep the trends there all the time. I actually don't even know where the data is stored, if at all. Thanks Tim.

Hi Tim. I already setup a Modbus TCP Slave in Studio 5000 for the Allen Bradley Controllogix L73 using Add on via Ethernet module EN2T install with same controller rack at slot 2, so I set MBTU_EnetModulePort is $01$02. and now i plan to set up a Modbus TCP Master using Add on via other Ethernet module EN2T installing in Remote IO rack (Controlnet node 3, slot 16). In this case, I don't know how to set MBTU_EnetModulePort. Please give advice. Thanks

Hey Tim, I am currently trying to get 1769 L33ER Compact Logix connected a cloud. I am using Microsoft Azure and i set up an IOT hub along with an IOT edge device that acts as a gateway. Additionally, I installed a Modbus module on the edge device in hopes to use the server AOI to be able to communicate with it. Do I only need to plug in the PLC's IP address into the moudle (client) for this to work? Also is this the best way to go about it? Any help would be much appreciated thanks!

Hi! I’m quite new to PLC programming. I am currently making a program that is responsible for shutting a projector and knowing its power state. I have now program that can send the command. The problem now is that i cannot receive the whole feedback (response) from the projector because read response buffer length appears to be limited to 9. I have read that i should do multiple read socket to receive entire application message but i dont know how to implement it.

Hey Tim, do you know if anything like this has been done on a micro 820? I'm trying to use an 820 to actuate a bank of relays, based on data from another widget that has modbus IP slave capability. Building a remote annunciator panel.

Hi Tim, I'm following your step-by-step guide to implement communication between a PLC and Studio 5000, however, my university computer does not allow the installation of Modbus Tools due to network vulnerabilities. Is there any alternative for me to complete the start of the Modbus server?

@TimWilborne Жыл бұрын

Sure, go ahead and connect a Modbus device. I used that device as a quick test for the video.

Excellent explanation, help please, if I want to communicate the 1769-L16R with a "HMI XXX" screen by modbus, the PLC must be a client or server? regards

So if I had tags I wanted to output over Modbus I could just copy the tag in another routine to the data.holdregister. Then using my other device point to that register and the PLC’s IP to read that tag data?

Yes, check out the AOI documentation when you download the sample code. It is very well documented.

Hi Tim, I have a Socomec (A30) power monitor on a project and it looks like the modbus client AOI would work for reading the data from the power monitor however the Modbus range starts at 50000 on the unit. Any idea how I could get the AOI to start at this range?

As long as the HMI supports modbus, all you have to do is enter the IP and address number.

I don't know. I've never found Emulate to do exactly what a PLC would do.

Thanks Tim, it's just out of curiosity since we can send and receive data on kepware so it pop-up on my mind that maybe we can use this AOI to command external devices.

what if I need float32 data instead on some 4XXXX registers? is there a way to change that? how can I send a message (string: 'unable to accept request')

@TimWilborne 3 ай бұрын

You would use a COP instruction to put the floating number into INTs then do the opposite on the destination PLC. Mainly pay attention to the length of the COP instructions. It is based on the destination. Here is a video where I'm doing something similar but with DINTs which are also 32 bit. kzfaq.info/get/bejne/pZl_irlptsW5Z6c.html

is using modbus from PLC to PLC a practical application or just for training purposes?

I wouldn't do it for AB to AB communications but it would allow you to easily communicate between an AB and an Automation Direct PLC or any other device that supports Modbus.

This is on my list of videos to make but use the CPS instruction to copy it to INTs then do the opposite in the other PLC. But pay attention to the length parameter in the help. It is based on the number of destination elements.

I just came into the need to use Modbus RTU in the 5380. Not nearly as pleasant to work with. Address changes require re-downloading the program each time as the config seems to be stored in the module like scaling is in a analog module. Can't change it online. Very disappointing during the development phase when you are trying to figure out how the data is structured. Modbus TCP on the 5380l is just like this video.

@TimWilborne 2 жыл бұрын

I'm not following you. Are you saying if you use the AOI on a 5380 that it won't let you change the address without downloading? It should work exactly the same.

@OldePhart 2 жыл бұрын

@@TimWilborne if you use RTU (serial) you need the 5069-serial module and the addressing is then done in the module config and not in the tags. Seems like a step backwards, but ab is really trying not to support anything serial.

@TimWilborne 4 ай бұрын

In a few years, no one will notice, remember MMIs? Honestly, Master/Slave has never made much sense and caused a lot of confusion. Most people thought the Master held the data and controlled the slaves. The slaves were the smart devices that held the data and the master could only read and write to them.
