You can use the same MCU (same ISA), same compiler, but you write different firmwares for different functions. You can use the same FPGA, same tools, but different VHDL/ Verilog codes to have different logic fuctions. You can have the same manufacturing lines, same PLC, same motor drive, etc, but you write different PLC programs to have different manufacturing process.
