5. Setup and Installation
Follow these steps for proper installation of your HMI PLC Combo:
- Mounting:
Prepare a cutout of 120mm x 94mm in your control panel. Insert the HMI PLC Combo into the cutout and secure it using the provided mounting hardware. Ensure a snug fit to maintain the IP65 rating.
- Power Connection:
Connect a stable DC 24V power supply to the designated power terminals (FG, 0V, DC24V) on the back of the unit. Refer to the wiring diagram for correct polarity.
Figure 5.1: Rear view of the HMI PLC Combo with labeled ports.
- I/O Wiring:
Connect your digital inputs (DI) to terminals X0-X11 and digital outputs (DO) to Y0-Y11. The digital inputs are Passive NPN, and outputs are Transistor (Low level NPN) or Relay (Normally open dry contact). For transistor outputs, COM connects to negative. For relay outputs, the max load is 5A; for MOS outputs, the max load is 2A.
If your model includes optional analog I/O, connect them according to your specific configuration. Analog inputs can support various types including Thermocouple, RTD, Voltage, and Current. Analog outputs support Voltage and Current.

- Communication Ports:
The HMI features one Type-C port for HMI program download and one USB 2.0 port. The PLC has one Type-C programming port and one RS232 port. Additionally, there are two RS485 ports (one configurable from the default RS232) and an optional WIFI module (occupies the default RS232 port).
Use the provided programming cables to connect the unit to your computer for software configuration.
- Software Installation:
Download and install the CoolmayHMI software for the HMI interface and Mitsubishi GX Developer 8.86 or WORKS 2 for PLC programming. These software packages are available on the Coolmay website.
6. Operation
Once the HMI PLC Combo is powered on and programmed, you can begin operation:

- Check the wiring for all affected I/O points as per the wiring diagrams (Figures 5.2, 5.3).
- Verify the PLC program logic is correct and has been successfully uploaded to the device.
- Ensure the input signals are within the specified voltage/current ranges.
- Communication Errors:
- Check the physical connection of the communication cables (Type-C, RS232, RS485).
- Verify communication settings (baud rate, parity, data bits, stop bits) in both the HMI/PLC software and the connected device.
- Ensure the correct communication port is selected in your programming software.
- Software Connection Issues:
- Ensure the correct drivers for the programming cables are installed on your computer.
- Close any other applications that might be using the communication port.
- Try a different USB port on your computer.
If these steps do not resolve the issue, please contact Coolmay technical support.
