CAN BUS Communication Using MCP2515 Module.

3 Arduino Nano are connected to the Controllino MAXI PLC using CAN Bus protocol #MCP2515 module. For demo purpose, each Arduino will send a random number to the PLC to simulate a value from sensor. The PLC is connected via USB to a PC running a Windows app (diagnostic tool) to display the status of each node. When a node is disconnected or malfunction, it will display as Offline. Any faulty device can then be removed and replaced without affecting other devices.

all that info over 2 wires sounds great ngl

[@destiny_02]

yes but 1-wire protocol would have been enough for this

[@scroogemcduckenjoyer]

Always used Modbus for my project (thank god all the devices I had supported that)
what's the advantage of CAN?

[@areitu]

Multiple data packets can be sent over a single twisted wire pair without packet collision and it can account for “noisy” environments because it uses using voltage difference for 1s and 0s

[@RzrxCrome]

@@areitu Modbus has all of that. I still don`t get the point

[@benevaldoalves8145]

Muitas vantagens, principalmente redução se cabos elétricos em projetos

[@davi5music521]

Just use stm32 or esp32 with can on board ;)

[@allyouneedis4x4]

no, you still need a transceiver

[@davi5music521]

@@allyouneedis4x4 yes but no can controler ;)

What do we call this display?

[@ToyTechMachines]

I'm using a normal display connected to a laptop using HDMI cable.

[@gtotv996]

How to connect to the wide monitor?

[@ToyTechMachines]

I use a HDMI cable and connect to a 7 inch normal monitor.

[@logic-bots]

What is this?

[@ToyTechMachines]

Controller Area Network

That's a lot of damage of all you are doing is reading three sensor data.😊
