I have Micrologix 1400 plc connected to Omron NS10-TV00b-V2 HMI. Micrologix 1400 has two serial ports (RS232/Rs485 isolated and 232c non isolated port). I want to connect second Same HMI(exect Mirror) to the PLC. what hardware will I need?
Omron HMI has two DB9 serial portA and Port B. And PLC has 8 pin Mini (RS232/Rs485) and DB9 (232) port. Also both has ethernet ports too.
Currently 8pin Mini from PLC connected to one omron HMI Port A.
