Connect ASCII Devices to an Allen-Bradley PLC

The perfect tool to connect Legacy ASCII systems to an Allen-Bradley PLC





Get Your ASCII Devices Connected Directly to the Data Table of Your Allen-Bradley PLC

The 460ETCA moves data between a serial ASCII device and 1 – 5 Allen-Bradley PLCs.

With the 460ETCA you now have a solution to get ASCII weather stations, UPS systems and any other ASCII devices that output a compound ASCII string connected to your Allen-Bradley PLCs. With the 460ETCA your ASCII devices are quickly and easily connected to user defined Tags or Registers in the data table of your Allen-Bradley PLC.

How Does the Data Move In and Out of the PLC?

Incoming and outgoing ASCII data is mapped to and from user defined tags or registers in the data table of your Allen-Bradley PLC. You allocate two areas of tags or register blocks in your Allen-Bradley PLC. One area is a user defined set of write only tags or register blocks accepting ASCII data. The other area is full of read only tags or register blocks to send data to your ASCII device. You directly map ASCII data into read and write locations in the data table of your Allen-Bradley PLC.

If your device uses delimiters, the 460ETCA can be configured to automatically remove the delimiters on incoming messages and add delimiters back in on outgoing messages. No need to deal with the delimiters in your PLC. If you need to parse your data, the 460ETCA can parse a string of ASCII data in up to 20 segments by delimiter or offset.

It’s designed to be a simple ASCII interface and it really is that simple.

Why Use Real Time Automation as a Gateway Supplier?

The 460ETCA provides an option to access those ASCII devices that always seem to creep into your architecture no matter how hard you try to keep them out. With the 460ETCA you can easily connect to those devices with your Allen-Bradley PLC.

When you call, a live person answers the phone. When you talk with sales, you will get honest answers and recommendations even if that means recommending someone else’s solution. When you get support, it is from an engineer who had a hand in the product’s development, and support doesn’t require a ticket or 24 hour wait. We are unashamed of the fact that we are a smaller company because that means you mean a lot more to us.

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.”
