There are currently over 50 different I/O boards supported by the UEIModbus. It supports all of UEI’s popular Cube/RACKtangle based AI, AO, DI, DO and CT interfaces. (Other Cube/RACKtangle-based products include the PowerDNA®, UEISIM™ and UEIPAC™ families.)
The Modbus messaging protocol is used to establish master-slave/client-server communication between intelligent devices. It is a defacto standard, truly open and the most widely used network protocol in the industrial manufacturing environment. Modbus devices communicate using a master-slave configuration.


The UEIModbus 600R HalfRACK functions as a Modbus slave that is easily accessed by any software client acting as a Modbus master. Most popular HMI software supports the Modbus protocol.
