Hi!
I'm an intern and a newbie in the field of automation. I was given the assignment to learn and program a PLC and HMI together.
PLC: Delta DVP80ES200R (DVP ES2)
PLC Software: ISPSoft 3.17
HMI: Delta DOP-112WX (DOP-100 Series)
HMI Software: DOPSoft 4.00.16
The problem I have is that the HMI and PLC don't communicate properly. The HMI sends the data to the PLC but the PLC doesn't send its' data back to the HMI (ex: If I press the M0 button at HMI, Y0 lights up in the PLC but the Y0 indicator in HMI does not).
I've been following this connection of HMI to the PLC: https://deltronics.ru/images/manual/DOP-112-115+Quick+start+manual_EN.PDF. It's currently connected by RS-485 COM1 (HMI) to RS-485 COM2 (PLC).
If you have other questions, feel free to ask me.
Thank you in advance!
