GoldenAero7 Posted April 5 Report Share Posted April 5 (edited) Greetings. I am developing an application that requires real-time data from FS. I have used "record to csv.lua" for reading values of specific parameters required through FSUIPC7. It is stated that "record to csv.lua" writes data into csv 20 times per second, which means the interval between each data would be 50 msec. However, after viewing the data in the csv file, i have noticed that the "msecs" values shows that there is an interval of 0.8~1 second between each data capture. I have inserted the csv file that was produced from a session I had on FS. As seen under the "msecs" header, the values increment by almost a thousand between each row which corresponds to a second. Is this behaviour normal? Is my assumption on the "msecs" values wrong in any way? Any enlightenment is greatly appreciated.

John Dowson Posted April 5 Report Share Posted April 5 There seems to be an issue with the speed of lua scripts when FSUIPC7 is auto-started by MSFS. Can you try manually starting FSUIPC7 - just exit it and restart manually, then try recording again to see if you get a faster rate. If I run this lua when FSUIPC7 is auto-started, I also see data logged at approx. 800ms intervals, as you do: Quote msecs,timeL,timeZ,lat,lon,alt(ft),pitch,bank,hdgT,hdgM,vs,ias,tas,gs,mach 47,10:08:00,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 938,10:08:01,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 1735,10:08:02,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 2531,10:08:02,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 3297,10:08:03,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 4094,10:08:04,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 4891,10:08:05,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 5688,10:08:06,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 6485,10:08:06,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 7266,10:08:07,0808Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 If I exit FSUIPC7, and restart it manually, I see data logged at roughly 63ms intervals: Quote msecs,timeL,timeZ,lat,lon,alt(ft),pitch,bank,hdgT,hdgM,vs,ias,tas,gs,mach 0,10:09:04,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 63,10:09:04,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 125,10:09:04,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 188,10:09:04,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 250,10:09:04,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 313,10:09:04,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 375,10:09:04,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 438,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 500,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 563,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 625,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 688,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 750,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 813,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 875,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 938,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 1000,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 1063,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 1125,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 1188,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 1250,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 1313,10:09:05,0809Z,42.2421,-8.6240,834.1,-1.00,0.13,191.4, 193.0,0,0,0,0,0.002 You can also speed things up further by reducing the delay in the sleep statement on line 58: ipc.sleep(48) Note that this was reported previously in the following topic, but I have only just realized that this is related to how FSUIPC7 is started: John Link to comment Share on other sites More sharing options...
John Dowson Posted April 5 Report Share Posted April 5 BTW, I have moved your post to the FSUIPC7 sub-forum - please use this sub-forum for all issues with FSUIPC7, not the main support forum. Thanks, John Link to comment Share on other sites More sharing options...
GoldenAero7 Posted April 17 Author Report Share Posted April 17 Thank you for the suggestion. I have tried to manually restart FSUIPC but the data is still logged at ~800ms intervals. The issue is still not resolved. I would appreciate it if you could have a thorough look into this issue. Thanks, Zamir Link to comment Share on other sites More sharing options...
John Dowson Posted April 17 Report Share Posted April 17 Can you please make sure you are using the latest released version of FSUIPC7, 7.4.11, or even better try the latest beta release, available from: and show me your FSUIPC7.log, FSUIPC7.ini and csv files. 5 hours ago, GoldenAero7 said: The issue is still not resolved. I would appreciate it if you could have a thorough look into this issue. As I said, I only see this here when FSUIPC7 is started by MSFS via the EXE.xml file, and I have no idea why this is. I will look at you files to see if I can see anything, but there is not much I can do. What is the load like on your system? What aircraft do you have loaded - if using an airliner, have you tried with a GA aircraft? John Link to comment Share on other sites More sharing options...
John Dowson Posted April 17 Report Share Posted April 17 Also, please activate logging for Lua Plugins, so that I can se the timestamps of the lua calls to see what is taking time - no other logging necessary, especially NOT Lua Plugins Separately.

Hence, I have pasted the contents of FSUIPC7.ini and FSrecord.csv as following. However, please advice on how i could share the FSUPIC7.log file as it is tremendously bigger in size.

GoldenAero7 Posted April 24 Author Report Share Posted April 24 Ah, I do get a rate of ~62ms after turning off the lua plugin logging. Seems like the issue has been resolved. Thank you very much for your assistance. Zamir Link to comment Share on other sites More sharing options...
