Please offer internal 24V power and external IO power separately, especially
when there is severe electromagnetic interference on site, 2 24V power supplies must
be applied, or one power that can offer 24V output with 2 channels isolation. When
serial port connects with touch screen, please use internal 24V power to supply touch
screen.
For communication quality, please use twisted pair shielded wire, and shield
connects with the ground, the internal power of controller and expansion module use
the same one.
When multi controllers are linked on CAN bus, it is necessary to connect 120 Ω
resistor between CANL and CANH of the last IO expansion module.
