HM HART Protocol Modems with Modbus Accumulator

Microflex HART - Protocol Modem

MicroLink-HM+ is a HART® protocol modem to USB/RS-485/RS-232 serial interface. In addition to functioning as a HART protocol modem, it can also be configured to continuously poll HART devices, filling Modbus registers with device values without any additional HART software. Modbus registers can be read using standard Modbus-RTU command 3 from the USB and/or RS-485/RS-232 serial ports.
