Have a requirement to log 3 to 5 data points (Real) from a Siemens S7-400 at 5hz for about 12hrs. so about 200ms ( faster if possible). The files or DB can be split and can be downloaded from the network or machine after 12 hours, so no need to "stream" the data.
What I do have is a Wonderware Historian only capable of logging at 1hz. I also have a SCADA server ( Wonderware 2017) and a connection between the PLC and the SCADA ( OI Server) on ethernet. I have code access to the PLC and a Siemens PG laptop.
I don't have cloud access, and this is on an air-gapped network. I need some easy, quick tools to log these points to CSV or similar quickly with minimal work for diagnostics. We only have 1 ethernet connection to the PLC through a scale switch and an older CP comms card. (I have remote access and a tech offshore to help me)
Everything is offshore, so don't have time to ship Hardware over easily to the offshore site, so can't use a red lion data station (or similar). What ever I do I need to be able to set up remotely.
