HMI Control Panel Communication Protocols 4-Wire Resistive Panel
RS485 Interface
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.

Description of Macro Communication Protocol
Receive data and send data is up to 253 bytes (Byte).
N63744 [0xf900] Length of received data (BYTE). (0 ~ 253)
N63745 ~ N63871 Received data The received data is stored from the
lower byte, that is, the first BYTE stores the lower 8 bits of
N63745, the second BYTE stores the upper 8 bits of N63745, and so
on.
When the system receives the data from the communication port, it
will store the data in sequence to N63745, and store the number of
bytes received to N63744.
N63872 [0xf980] Length of data to be transmitted (BYTE). (0 ~ 253)
N63873 ~ N63999 Transmitted data The transmitted data is stored
from the lower byte, that is, the first BYTE stores the lower 8
bits of N63873, the second BYTE stores the upper 8 bits of N63873,
and so on.
When the system recognizes that N63872 is greater than 0 and less
than 254, it will begin to transmit the data at the variable
position of N63873 to the number of bytes recorded by N63872.
Commands sent twice. (When data is sent to the communication
buffer, the system will sequentially send the data to the
corresponding communication port)
Software "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.
