Greetings of the day
sir, I'm confused about the selection of the best option for my project I hope you can help me to select
My project is monitoring Energy system of our plant from our main SCADA (Site and SCADA are having much distance)
PLC - PM583 Eth SCADA-CHMI 6
Programming on both sides are fine and the confusion is on the communication side
Which communication should I use
1:As the distance is likely less than 100 meter using a GSM modem on the plant, collects data in SCADA PC as TCP server and moves it to any OPC like Kepware, as CHMI only supports OPC communication
2:Data tunneling through the internet. CoDeSys OPC will be used
3:Using VPN and making a virtual connection to the plant PC and collecting value
All the above notes are made by surfing through the internet if anything not correct please correct it Also let me know which will be the best solution for me from my notes or any other alternatives
