I am using Siemens 1516 F PLC, Earlier the SCADA was developed with ethernet TCP IP communication protocol. For time being we are having an issue with the server installation so that the client wants to have the stand-alone PC for SCADA (Means without server, PLC will connect to the SCADA PC). The problem is that the client not allowing to assign the IP or set the dynamic IP on the SCADA PC. They wanted to go with serial communication for SCADA and PLC Communication. My questions are the following
- Can I use the serial communication for the SCADA with the Com port on the PC?
- Real-time visualisation is possible with the serial communication?
- If it is possible, Can I use RS485 o RS432 communication?
- How many tags can we use for the SCADA(Limitation)?
If there is any other solution Please let me know, I need guidance to solve the problem.
