The C-More HMI Panel software uses popup system default keypads. I recently was asked to enlarge the keypad to make editing easier.
We will now look at enlarging the existing system default keypads. This is especially good with touch screens over 10 inches. We will also look at how to define a custom keypad for the C-More HMI. Let’s get started. Continue Reading!
The C-More HMI Panel software uses virtual components called Objects. These objects are programmable to simulate the functions that you require on your automation project. Pushbuttons, Switches, meters, and graphs are just a few of the objects that are available to you.
The recipe object changes the value of a tag or multiple tags.
We will now look at the object list recipe that we can use with our HMI panel. The recipe objects that are available on the C-More EA9 are Recipe and Call Recipe. Let’s get started. Continue Reading!
We will now look at the C-More panel settings for communication to the PLC. The C-More EA9 HMI (Human Machine Interface) Series Panel will communicate to the PLC directly through the tag database that we discovered in our first program. We were able to read and write individual bits in the PLC.
Panel to PLC communications is used to write information into the PLC; like current screen number displayed, good communications, pop-up keyboard, and current language number used in the HMI.
PLC to Panel communications is used by the PLC to control the HMI. Switch to screen number, beep, increment and decrement the Clock by one hour, clear alarm history, clear alarm count, start screen saver and select language are the items you can control in the HMI.
PLC Error is used to communicate internally in the HMI the PLC error state and PLC error code value.
We will be setting up and testing our PLC to Panel and Panel to PLC communications on our EA9 C-More. Let’s get started. Continue Reading!
We will now look at the C-More EA9 system hardware. This will include unboxing and powering up our C-More unit. Human-machine interfaces (HMI) are made to display and control operations for our automation solution. Information is displayed in a graphics 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.
C-More Operator Panels come in 6”, 7” wide, 10”, 10” wide, 12” or 15” models. They are programmed using the EA9-PGMSW programming software through either the USB or Ethernet cable. A voltage supply of 12-24 VDC is required for the panel. The optional C-More AC Power Adapter EA-AC can also be used to supply this voltage.
We will be looking at one of the newest members of the C-More Panel HMI devices from Automation Direct. This is the EA9-T10CL. This ten-inch colour TFT LCD screen offers great features that we will be exploring as we review this product. Let’s get started. Continue Reading!
