On this post it showed how to implement a TCP server on Touchberry Pi 3 The requirements of this post is just a Touchberry Pi with internet connection. To get the Node.js JavaScript interpreter we need to install the command cURL on our Linux. cURL command is  very useful for HTTP/S requests. To get the cURL we just need to type on the Linux Terminal: sudo apt-get install curl   Once there is the cURL installed we can download the node source typing…

Modbus TCP M-Duino

Modbus TCP M-Duino

Modbus TCP can be programmed in M-Duino PLCs. It’s required to install Industrial Shields boards. Follow this link to download our boards.  Basically, this example links holding registers 40000, 40001 and 40002 to outputs Q0.1, Q0.2 and Q0.3 of the M-Duino. In this way these 3 outputs can be operated via a Modbus TCP master. You will have to modify the IP address and network parameters according to your LAN. An illustrative and simple example to test the application is…
