Even though Ethernet is the current standard for industrial communications, there are still an awful lot of Modbus RTU devices out there. There are a ton of perfectly good scales, flow meters, drives and lots of other devices that use Modbus RTU messaging. This is equipment that you've probably used for a long time and are comfortable with. You know how to set it up, how to make it work and you know that it's reliable. Plus, you can probably get it at a really good price since it doesn't have all the fancy features of the new models.

The problem is that you still have to get these devices and their data into your PLC or HMI over a Modbus TCP network. And a lot of the time now we don't have serial port to use and if you do, you need to get a 232/485 converter. If you set all that up, you've probably thought, "Shouldn't this be easier?"

Well, that's what our device is for. It makes moving Modbus RTU register data to a Modbus TCP Client simple. It quickly and easily moves the registers you need from those scales, drives and other RTU devices to Modbus TCP Clients like Wonderware and other HMIs without all the hassle. Here's how you do it:

When you get done, the device starts reading all the registers you specified and storing them in the module. All those registers become immediately accessible as Modbus TCP Server data using the same register addresses as they have in the Modbus RTU Network. That means that the mapping is trivial. Register 100 in Device 2 is simply Register 100 UID (Unit ID) 2 in the Modbus TCP Server. In case, you are not familiar with UIDs, this is a standard Modbus TCP field designed specifically for this type of application. Using the UID field, you can access any register data of any Modbus RTU device just as if that device was directly on the Modbus TCP network!

It's Easy! So Easy that we will let you try it for 45 days with a no questions asked return guarantee. You don't like it, you don't like the documentation, we'll happily take it back.

The Legend Begins

"It’s likely that your business isn't industrial networking. And it shouldn't be. You make products, products that do wonderful things. Whatever it is that you make the process creates data. If you're a control engineer and your plants been around for more than a few years your plant floor is probably littered with devices that send out all kinds of data, and in most case data talking in a lot of different protocols. If you're an automation device developer you probably need to move your data into some other network. Either way, you've got a device conversion problem. You have devices that generate ASCII data, Modbus RTU, Ethernet TCP Data, DeviceNet data or some completely proprietary data and now you're the guy that has to move that data to some other network!

I feel your pain… and better than my sympathy I have a solution for you. You see while your business isn't moving data around the factory floor mine is. In fact it is all we have done for more than twenty years now. Our PLC series Gateways is the culmination of those twenty years. You can now move all of your data, where you want, when you want and how you want. Best of all THE HARDEST PART IS OPENING THE BOX".
