Move Your Data Anywhere
You have just found the easiest way to move ASCII serial data into a MicroLogix, ControlLogix, CompactLogix, PLC-5, and SLC5/05 Allen Bradley PLC over EtherNet/IP. Sure everyone offers ASCII to EtherNet/IP gateways, but nobody offers one quite like this. We are not offering just some off the shelf gateway. This is an ASCII to PLC gateway. Not only do our Gateways convert ASCII serial data to EtherNet/IP, they convert the data and write it directly into your Allen Bradley PLC. It’s so simple we guarantee it. If you don’t agree this is the easiest and quickest way to move ASCII data into a PLC, we will buy the unit back.

Device Compatibility
Even though Ethernet is the standard, there is still an awful lot of ASCII data out there. There are a ton of perfectly good scales, barcode readers, RF ID devices and a multitude of other units that generate an ASCII string. This is equipment that you’ve used for a long time. You know how to set it up, how to make it work and that it’s reliable for you. Plus, you can probably get it at a really good price since it doesn’t have all the fancy features of the new models.

What, exactly, makes our Gateways the best around? First, our gateways feature simultaneous dual port functionality. This allows you to connect two ASCII data devices to a PLC with just one gateway. This may seem like a hassle to program, but it is surprisingly simple. In fact, there is no Ladder Logic to program at all.

We take any data that is transmitted into our barcode to PLC gateway and instantly send it directly to a tag or register in your PLC. The same principle is used when transmitting data from the PLC to the ASCII device. As soon as we see ASCII data or data from the PLC in the register of the ASCII to PLC Gateway we send it on its way. What could be simpler?

Simpler is better
Why wrestle with hours of programming and tedious ladder logic to integrate a simple gateway. Why deal with 50 additional features on a product you don’t need? Or pan through hundreds of pages of a manual just to get your unit configured? With our Barcode to PLC Gateway you don’t have to deal with any of those things. You can easily have our unit up and running in less than 5 minutes.
