Dear Expert, I read from this site, that S7-1200 can be connected to PC using S7-200 PC access, but also can use Simatic Net OPC Server. I want to connect multiple s7-1200 to a PC, which one should I use? What is the difference, I know that PC access only can read DB1, any other difference? Can PC access connect to multiple PLC? Thanks.

Hello, Using Simatic Net OPC Server -http://support.automation.siemens.com/WW/view/en/39960680 PC Access has a limitation of 8 CPUs which number also can be 'masked'. How many CPUs do you want to access? My suggestion is to use Simatic Net. Best regards, Hristo Mihalev
