ok i got 6.1.7 I rolled back from 6.1.8 and now i can change the ZFW. So there is a issue with FSUIPC 6.1.8

I'm not sure about that - there are very few changes between 6.1.7 and 6.1.8 - only the following:
   - Bug fixed that prevented assignments to buttons with numbers 64 – 95 from being triggered
   - New functionality to allow the user to add any simvar to a free FSUIPC offset

Looking at that link, this was your issue:

Quote

In the CDU or IOS weight page setting all pax and cargo to zero the ZFW is stuck on 54832 and does not change what so ever

 

I'm not sure how this can have anything to do with FSUIPC... Can you try 6.1.8 again to confirm please.

As I don't have/use Prosim, I'm not sure what I can do. I'll see if @Pete Dowson can check this as he uses the ProSim  737 (probably later next week, after the Bank Holiday).

Very strange one. Soon as i rolled back to 6.1.7 the load was then able to change the ZFW.

Yes, this is what you reported. I was just suggesting to try 6.1.8 again to confirm. The problem only seems to occur in the latest ProSim beta as well, which also indicates its not an FSUIPC issue. Anyway, talked to Pete about this - he is aware of this issue and will check later next week.

I rolled back previous BETA’s and still had the issue with 6.1.8

Thanks

Humberto kindly explained to me how ProSim computes the ZFW from FSUIPC offsets. He said:

Prosim is calculating ZFW. It is getting gross weight from offset 30c0 and subtracting fuel from offsets 0b80(capacity) 0b7c(level) : example for 1 tank only, corresponding offset used for the other 2 tanks

 So, I made a Lua plug-in to compute it the same way, whilst changing the payload a number of times. This showed absolutely no difference between FSUIPC 6.1.7 and 6.1.8 for the offsets Prosim is using. For your information I attach the Lua plug-in.  It logs the results in FSUIPC6's log. Here's the results for my office version of P3D5.3.  Each loop is increasing the weight in the 9 payload stations by 100 lbs, so increasing the payload total by 900 lbs on each loop -- in the log the loop ends are denoted by the line with ******...

For each loop the ZFW is being calculated in the exact same way as Humberto states for ProSim. This is shown in the lines like   796781 17024 LUA.3: Computed ZFW = 105715.36461655

I've also checked the values against those shown in the P3D Vehicle - Fuel and Payload display.

As John says, there's really no change between 6.1.7 and 6.1.8 which could result in what you are observing and they certainly both behave the same with this test.

I should be able to get my cockpit up and running tomorrow, and then I will double-check when actually using Prosim. I'll update first to 3.17B20 (or later if another is released).

Okay, I've tested this on my cockpit, with ProSim 3.18B1.

The ZFW (and other weight components) change correctly when altering the pax and cargo loading in the P3D Fuel & Payload menu, and also when using FSUIPC to write to the payload station offsets.

But nothing changes except the total pax or cargo values in ProsinIOS and the CDU when changing loadings via the IOS or CDU. Nothing is written to the payload offsets.

I don't see how this can be down to FSUIPC, but I don't understand what ProSim is using to change the loadings in P3D. So I'm going to ask Humberto for more information.

This issue is caused by bulk writing to an offset area when some of the offsets are not in the offset table. ProSim is bulk writing the payload data including the position data, which don't exist in the (internal) offset table for P3D. This error was introduced in 6.1.8.

This should be fixed in the attached version, v6.1.9a, if you would like to try: FSUIPC6.dll
