I have project with WinCC scada v7.0 where I have visualization for simatic s300 PLC with E200 communication modul and it work OK. Now I want to use the same SCADA for visualization of more 5 existing PLCs unitronics visio.
1. If it is possible with modbus, would you like to tell me what type of CPU is unitronics (premium, 984, quantum, etc)
2.The unitronics PLC support OPC server. If it is better way for communication, would you like to send me exapmle how to configure WinCC as OPC client, because in online help I can not understand how to do this.
3.Unitronics PLC support DDE server and it can write datas in excel table. Can WinCC scada read datas from excel table and if it is possible, how to do this?
Thanks in advance
