I want to connect an EZMarquee (EZMR-2L20C) to an OMRON PLC: CQM1H-CPU21 and also a G306A Red Lion HMI. This PLC has just one built-in RS-232C port that I will use for the Red Lion HMI.
The EZMarquee uses ASCII RS-232/422/485. Do you think it would be possible to connect the EZMarquee too? I don't know if somebody has done something like this. I was thinking maybe using one of the RS-232C ports of the Red Lion HMI to write to the Marquee or I'm not sure if thru RS-422/485 it could be possible to control both. Any help is welcome. To add a serial board implies changing the processor (CPU51/61) adding like a $1000.
