No, there is no Master part plan.

Project has been done to made a fun slave for a training course on plc. What is important is the plc course part, and having one slave
capable to interact with of all the plc I/O : 24V all or none, analogic, modbus over rs485, modbus over tcp.

For now we are stuck waiting for NCV7719 spi half bridge availability. We have the pcb since 4 month, and the chip is out of stock since :-(
