Web6 feb. 2024 · Modbus is much simpler than Ethernet, though it can be 'packaged' into Ethernet packets. Modbus controllers are often called 'nodes', and may have a Ethernet or USB socket to connect to a PC. The output of a node is usually a 26 wire ribbon cable that connects in a chain with I/O boards that directly control things, or read sensors.

WebModbus is transmitted over serial lines between devices. The simplest setup would be a single serial cable connecting the serial ports on two devices, a Master and a Slave. The data is sent as series of ones and zeroes called bits. Each bit is sent as a voltage. Zeroes are sent as positive voltages and a ones as negative.
