I/Os Communications
RS485
The RS-485 is a half-duplex serial communication. The 10 I/Os PLC uses the MAX841CSA for the
RS-485 communication. In the following photo you can see the internal schematic of the PLC of
the connection between Arduino NANO pins, the RS-485 chip and its outputs.
Using the boards of Industrial Shields, there is a library that simplifies the RS-485
implementation.
Ethernet
10 I/Os Ethernet port controller is based on w5500 IC, which is the IC compatible with Arduino
Ethernet2 Shield libraries. All Ethernet shield Arduino libraries are compatible with the 10 I/Os.
In the 10 I/Os, W5500 IC communicates to the NANO board via SPI bus.
