Parameter:

TK series HMI applied Coolmay software “mView”. “mView” is a set of stable and reliable human machine interface programming software for industrial occasions. Independent and original system design, running speed increased by 200%, memory usage reduced by 50%.
It supports many communication protocols and can communicate with more than 200 PLC and controllers on the market.

mView editing interface layout:

●Title bar: Displays the currently opened project path and file name, window number, and window name.

●Menu bar: A menu that displays various commands of CoolMayView. These menus are pull-down menus.

●Standard toolbar: Shortcut buttons for placing some commands. Corresponding buttons and editing tools for displaying files, editing, printing and other functions.

●Design components: Command buttons for component objects.

●Screen management: The management window of the screen used by the project.

●Communication management: engineering designers to manage, set up a window to communicate with PLC or other serial devices.

●Label management: Set labels for system variables and external variables to facilitate users to quickly find the corresponding variables.

●Status bar: Displays the current operation status, human-machine interface parameters, and communication equipment.
