 Overview and User's manual

The ComfileHMI is a WYSIWYG development kit for HMI projects.

CHA-070WT is very similar to the CHA-070WR, but without Ethernet and an RTC backup battery.  It offers a more cost-effective alternative for those use cases that do not require those features.

  • Supports Modbus RTU and ASCII
  • 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 (Included with purchase)

The ComfileHMI can be used to control the CUBLOC, MOACON, FA-DUINO, MODPORT, or just about any other Modbus-capable PLC or microcontroller.  The MODPORT is a particularly suitable companion to the ComfileHMI as it does not require any PLC programming.
