MODPORT
The MODPORT is a modular, Modbus RTU field I/O controller for I/O control and data acquisition. Each module operates as an independent Modbus RTU slave, and each channel is individually or collectively addressable.
It can be interfaced with our CPCV5, CUWIN, and ComfilePi panel PCs, or with any Modbus RTU master, but is an especially excellent companion to the ComfileHMI.
No programming is required! Just connect a Modbus master via RS-485, set the Modbus slave address of each module, and it just works.
A wide variety of modules are available so you can configure your system specifically to your application's needs. Individual modules include Digital I/O, Relay Output, Analog-to-Digital and Digital-to-Analog Conversion, Temperature Monitoring, and the potential for more.
