We will now unbox and review our C-More Micro hardware. Human machine interfaces (HMIs) are made to display and control operations for our automation solution. Information is displayed in a graphic format. (Graphical User Interface – GUI) The HMI is usually part of the SCADA (Supervisory Control and Data Acquisition) system.
Communication from the HMI to the control is usually done through a serial (RS232 / RS485 / RS422) or Ethernet (RJ45) method with different protocols depending on the manufacturer of the control. The automation control device is not limited to a PLC. (Programmable Logic Controller) You can communicate also to drives, temperature process controllers, etc. The HMI usually will include several different protocols and port configurations to maximize the amount of control product that it will be able to communicate.
We will be looking at one of the newest members of the C-More Micro Panel HMI devices from Automation Direct. This is the EA3-T4CL. This four-inch color TFT LCD screen offers great features that we will be exploring as we review this product. Let’s get started.
Here is a detailed list of the HMI touch screen.
C-More Micro Hardware – EA3-T4CL Features:
• Touch screen display
• Free downloadable programming software
• 482 x 272 pixel display (WQVGA) with up to 40 lines by 80 characters of text and graphics
• 32K colours
• Optional clear screen overlay
• 14MB memory
• Built-in USB type Micro-B programming port
• Built-in RJ45 Ethernet Port
• Built-in 15-pin serial communications port
• Built-in RJ12 serial communications port
• Built-in Alarm Control setup that activates beep, backlight flash, customized alarm banner, and red LED blinking
• 0 to 50 °C (32 to 122 °F) operating temperature range (IEC 60068-2-14)
• NEMA 4/4X, IP65 compliant when mounted correctly, indoor use only
• UL, cUL & CE agency approvals
• 2-year warranty from date of purchase
The EA3-T4CL is powered by a 4W 12-24VDC supply.
Communication is usually what sets apart HMI systems. The CMore Micro EA3-T4CL has 3 built in ports for communication to your control system and 1 port dedicated for programming the unit.
The above diagram will show you the ports and pinouts for the HMI. Please refer to the manuals listed below for the exact cable for your automation equipment.
The following table will show you the communication drivers that have been written for the EA3 Series of C-More Micro Panels. Generic protocols like Modbus TCP and Modbus RTU can be used on numerous automation products.
