Description: The communication protocol will be downloaded to the model along with screen data, PLC needn’t compile communication program.
Can connect with nearly all PLCs popular in the current market, such as Mitsubishi FX series、Omron C series、Siemens S7-200 series、Koyo SG series etc.
With password protection function
With alarm list function, real time display the current alarm information line by line.
26 function keys, each function key can be defined freely
Add touch function which make control more easily
Freely choose communication format, any one of RS232/RS422/RS485
Add vector text and vector buttons which make the project screen more expressive
With backlight STN LCD display, normally it can display 24 ASC×4 lines. If use the vector units, it can display more information!
The display’s surface is IP65 structure, water-proof, oil-proof- The communication protocol will be downloaded to the model along with screen data, PLC needn’t compile communication program.

Description: 单片机（stc89c52）通过RS485与PLC通信，采用modbus协议，利用单片机闲置的一个管脚置高或低，来判断出现单片机程序执行的情况。硬件连接比较简单，单片机通过485的A/B端连接到RS485/RS422，RS422连接但PLC。这个就是.c程序不是工程文件，下载后自己建立个keilC工程就可以了。-SCM (stc89c52) via RS485 communication with the PLC, using modbus protocol, using SCM idle a pin high or low, to determine the circumstances microcontroller program execution occurs. Relatively simple hardware connection, the microcontroller 485 A/B terminal is connected to the RS485/RS422 through, RS422 connection but PLC. This is not a project file .c program he established a keilC project after downloading it.
