What our Customers are Saying

“The 435NBA is an excellent serial to EtherNet interface to an Allen-Bradley ControlLogix PLC. We had our barcode scanner up and running within a day with your tech support. Great web interface makes it easy. We will be using more of these in the future.”

"Industrial automation domain experts – the guys who build a lot of valves, pumps, drives, etc,, and need a way to talk to their devices – will find their Modbus champion in John Rinaldi. The author has almost as much shop floor experience as Modbus itself, the 40 years it’s been (and remains) the sole open source electronic networking protocol for connecting automation systems. John brings his trademark passion for, and quirky treatment of, all things industrial automation, to Modbus in the 21st Century. Internet of Things? OPC UA? All good – but automation engineers for whom small, simple, cheap, fast solutions will suffice will walk away from this book joining John in declaring ‘Hail Modbus! Modbus forever!"
