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…

Real time electrical consumption monitoring with M-Duino

Real time electrical consumption monitoring with M-Duino

In this Project, we will show you how to read electrical consumption using Modbus communication. Modbus is an industry standard communications protocol for electronic device Hardware I: Equipment to be used The electrical consumption monitoring system consists of: An M-Duino PLC: This controller is the heart of the system. It controls the display, generates interrupts, and controls the communication. A Panel PC: Used to read on the status of a counter and display the graph of monthly consumption over the Panel…

How to Modbus-Ethernet

How to Modbus-Ethernet

Modbus is a Serial communications protocol and it is used for communicating with several industrial devices. It may run over RS485, Ethernet, or whatever hardware interface. If we have an ethernet connection between a lot of devices, we can use this hardware connection (eth), and over it, we can use our own protocol (custom protocol,…), or for instance, Modbus protocol. The way is the same as using RS485, but hardware connections will become much easier, the speed will be higher, and…
