Move Your Data

Even though Ethernet is the current standard for industrial communications, there are still an awful lot of Modbus RTU devices out there. There is a ton of perfectly good scales, flow meters, drives and lots of other things that use Modbus RTU messaging. This is equipment that you've probably used for a long time and you're 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 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 this stuff 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:

1. Start the web server and configure your first Modbus device. Enter its Modbus RTU Address and a set of registers to read and a set of registers to write. You'll have to tell it the number of registers and their starting address.

2. Repeat this for every Modbus RTU device you have.

3. If you have a second or third set of registers you need from one of your devices, enter your device again and again, each time specifying a different set of registers.
