## Description
-The M5Stack PLC Module is a prototye industrial board, including RS484
-adapter and electricity meter module.
+**PLC** is a Base for an industrial application. This base has power conversion and TTL level to RS485 level function so that you can realize 9-24V voltage application with it. Realize TTL level to RS485 level output function after soldering the RS485 adapter board to this base core board.
-With DC9~24V power input, PLC-Proto motherboard reserved 6Pin or 4Pin
-relay output, digital input, communication interface etc.
+**The current sensor (ACS712TELC-05B)** is also integrated on **the RS485 adapter board** for current monitoring.
+
+
+
+The following picture shows this base core board and the RS485 conversion board. You can connect the specified pin on the M-Bus bus to the 6 Pin 3.96H terminal on the right by soldering the wire. And It is also possible to solder the RS485 converter board to the lower right of the core board to achieve serial port 2 (UART2) to RS485 level. The RS485 output interface is the 4 Pin 3.96H terminal block below the core board.

## Description
-**WEIGHT** 是一款集成了专用于计重秤设计的ADC芯片 **HX711** 的计重 Unit。
+**WEIGHT** is a metering unit that integrates an ADC chip dedicated to the scale design.
-* 因为 Unit 接的 GROVE 口,所以相对 Unit 里的 HX711 来说,激励电压 (Positive Supply Voltage) 是 +5V,信号输出给M5Core的电压范围是 0 ~ 5mV,施加的压力越大,对应输出的电压值越大。
+* Because the Unit is connected to the GROVE port (the GRVOE port is a 5V supply voltage), the positive supply voltage is +5V for the HX711 in Unit. Output voltage range is 0 ~ 5mV. The greater the applied pressure, the greater the voltage value of the corresponding output.
-* HX711 有两个输入通道A, B。相比通道 B,通道A具有可编程信号放大倍数,该 Unit 的电路设计中,使用了通道A,所以这个Unit具有可编程的放大功能。
+* HX711 has two input channels A, B. Compared to channel B, Channel A has programmable signal amplification. Channel A is used in the circuit design of this Unit, so this unit has programmable amplification.
-该 unit 一端连接压力传感器,另一端通过 GROVE 线连接 M5Core,下图是连接示意
