There is an old Klockner Moeller PS316 PLC (CPU-W: EBE 223.1 -5) with an electronic board as a text HMI (by using RS232 to RS485 converter). This HMI(Electronic Panel) is SYNTEC-Synatronic. I'm going to replace this HMI by a new one, but I do't have the program of the PLC and HMI. My question is: 1- Is there a touch screen HMI that can be connected to this PLC easily? 2- How can I find the addresses of those PLC flags that used in HMI? Thanks, Sasan
