  •  CHC-070WR - 7" Water-Resistant Human Machine Interface (HMI)


The ComfileHMI is a WYSIWYG development kit for HMI projects. Supports interfacing with the CUBLOC, MOACON, FA-DUINO, MODPORT, or just about any other Modbus-capable PLC or microcontroller. The CHC series has a faster processor than CHA, so the execution speed is faster.

  • Supports Modbus RTU, ASCII, and TCP
  • Water-resistant and open-frame models are available. 
  • No branding on the hardware's front panel (logo-less). 
  • Supports TrueType fonts and Unicode for creating multilingual user interfaces.
  • Supports PNG, JPG, and BMP image files.
  • Water resistant front panel models support audio output (e.g. .wav files)
  • microSD card support for additional memory
  • Supervisory remote control over Ethernet
  • Remote scripting
  • SD card is not needed to run projects (projects are stored on the eMMC), but SD card is needed for logging.
