Get Your Modbus RTU Master Connected Directly to the Data Table of Your Allen-Bradley PLC
The 460ETCMRS moves data between a Modbus RTU Master device and up to 5 different Allen-Bradley PLC’s. It’s a simple tool to help you integrate legacy or low cost Modbus RTU controllers into your Allen-Bradley Architecture.
Best of all the product is Made in the USA, is always in stock and comes with 5 year warranty.
How Does the Data Move In and Out of the 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 data from your Modbus RTU device. The other area is full of read only tags or register blocks to send data to your Modbus RTU device. You directly map Modbus RTU register and coil data into read and write locations in the data table of your Allen-Bradley PLC.
It’s really that simple. Need to modify your data as it passes from one protocol to the other? No problem. Each data mapping you apply can be modified.
Why Use Real Time Automation as a Gateway Supplier?
The 460ETCMRS provides an option to access Modbus RTU data without having to upgrade your PLC or get an expensive in rack solution. While there are certainly a number of other companies offering stand alone gateways, there is no one who provides the level of support and service that you receive from RTA.
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.
