I tried connecting the dot counter to the MZ platform by serial communication
Overview
MZ the dot counter requested by the local company Precision Press Kogyo Co., Ltd. I tried to connect to the platform.
RBI with a dot counter and a notebook PC connected (Fig. 1)
--Connected to a laptop with a USB serial cable.
Appearance of the dot counter (Fig. 2)
――The largest square device is the main body. ――The 7-segment LED displays the number of finished products, the number of hit points, and the set points from the top. --The small square device is the relay device. It is a circuit box for connecting the sensor that matches the main body and the machine tool. --A sensor (limit switch) is attached to the end of the cable extending from the relay device.

――In addition to the limit switch, you can change the sensor according to the environment, such as a magnetic sensor.
Laptop side setup
You need to install the USB-serial conversion cable driver on Windows.
What I did on the MZ platform
This time, I only checked the operation with the sample program that is included in the MZ platform.
procedure
- The dot counter and the notebook PC were connected with a USB serial conversion cable (Fig. 1).
- Open the sample program (serial communication terminal.mzax) of the MZ platform (Capture 1).
- I pressed the execute button.
- Select the COM port and press the open button to connect (Capture 2).
- The sensor part of the dot counter (press the limit switch: Fig. 3) was operated.
- The number of dots from the dot counter is displayed on the communication monitor screen (Capture 3).
- When I pressed the close button, the connection was disconnected (Capture 4).
Capture screen
--Screen at startup (capture 1)
--Connected (Capture 2)
--Communication data was received on the MZ platform in response to the sensor (Capture 3)
--I was able to disconnect with the close button (Capture 4).
Program screen output
The MZ program is output as a BMP file. Since the size of BMP is large, it is converted to JPG and posted.
