Serial communication card
RS-422A/485, RS232C | CQM1H-SCB41
OMRON
*
Unlike the CPU Unit’s built-in ports, the Serial Communications Board supports the protocol macro function which can improve communications between the CQM1H and external serial devices.
*
The Serial Communications Board has 2 ports: an RS-232C port and an RS-422A/485 port. The RS-422A/485 port supports 1:N connections (protocol macro or NT Link in 1:N mode) with-out an adapter.
