Moving Ethernet TCP/IP to a PLC Made Easy
There are a ton of perfectly good scales, barcode readers, printers and display devices that communicate with TCP data. 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.
The problem is that you still have to connect these devices into your Allen-Bradley PLC. That means writing and testing PLC logic. Not hard – just another task to do and more code to support. But there is a better way, a much better way. If you could move the data right into the PLC’s registers, it would save you time, money and a pile of headaches
That’s the device we have developed for you. The 490NBX easily connects ASCII Ethernet TCP to Allen-Bradley PLC. Quickly move barcode data, weigh scale data and other TCP device data. It moves your raw TCP data to a PLC with little or no delay. Milliseconds after receiving your raw TCP data, it is transferred to your user-specified tag in the PLC. Simply configure the input data format, the IP address of the PLC and a PLC tag using a very simple browser interface and you are ready to run. No standalone or custom software is required. It’s that simple.
How the 490NBX Works
Finally, You don’t need to use message instructions to move data into a PLC. We have found a simpler way to send the data. You define a tag in the PLC for our unit to monitor. Our unit watches the string length and anytime it sees a non-zero value we send that data and set the string length back to zero.
Whenever we see data in our unit from your device, we send it out to a tag in the PLC. On the TCP device side, we transfer raw TCP data. Our unit can connect to your device by imputing the device’s IP address or it can wait for the device to connect to it by leaving the address 0.0.0.0.

Is It Really that Easy to Connect ASCII Ethernet TCP/IP to an Allen-Bradley PLC?
Yes, these units are so popular because they are so easy to set up. There is no software to download or code to write. You simply map the tags to monitor and set your device’s connection and you are done. This is all done via a built-in browser-based interface. You pull up the webpage and enter your configuration. The whole thing can be set up in less than ten minutes.

What our Customers are Saying
“I challenged a customer to get it working by the time I got back from his break room with a Coke and he indeed had it working when I got back. He then said, "It’s worth twice the price!"”
Eric P. / Kendall Electric
“Everything seems to be working as we imagined. Thanks for the great response time. I did not see any way to save the configuration other than screen shots, but the configuration did not get lost in the update. Thanks again, and you were a pleasure to work with.”
