Can I connect my HI 4050 or HI 3000 to a PC?

The HI 4050 has Ethernet IP, Modbus over Ethernet, RIO, Profibus and DeviceNet options available for bi-directional communications. It also has Analog Output (both voltage and current) available for transmitting an analog signal to a PC. You can connect a PC or PLC to your HI 4050 through one of these connections.

The HI 4050 and HI3000 series controller have a serial output port to go to a printer or external scoreboard display. They do not have a bi-directional serial port.
