I am starting a new design and I have a few options for this. I am looking at using a MP370 touch panel for the HMI. I don't need much of a plc but I do need about 20 inputs and 20 outputs. My first thought was to use a S7-200 but after doing some checks I found that I could get a soft-plc (WinAC MP) that would run on the MP370. This would be good because I could use the ET200S I/O that I use on my other systems. I am still waiting on quotes for both options.
So has anyone used a MP370 with WinAC? I use WinAC RTX on PC's all the time without any problems. But I worry about how fast it will be, will it slow down screen loading. Doing some searching on this site I find some old post of scan times of 50ms working good but 30ms slowing down the screens. Is that still a problem?
Another question is remote connections. I am planning on getting the smart service option for the panel. This should give me the web page information and stuff but wont help me make changes in Step 7 or WinCC Flexible. I will have an internet connection and a VPN to the customers network from my PC at the office. Once connected to thier network via the VPN will I have a problem connecting to the panel/PLC?
Any suggestions?
Thanks
