One crash of the OCP4747X during an MCP altitude change

[dornier]

Hi,

I was cleared to FL320 and as I rotated the altitude knob clockwise, the MCP digital altitude started going the wrong way. Instead of increasing it decreased and I couldn't set it above somewhere in the 20,000' range. I few seconds later the OCP4747X program crashed. I closed SIOC and the OCP4 menu interface and just restarted it and it worked fine after that. Not sure if it was just a one time issue.

Thanks,

George

If you can recreate the issue I will look into it.

Hi Roar,

During a flight today, I received the "OPENCOCKPITS driver 4 PMDG B747X has stopped working" twice. Each time I was able to shut down SIOC and OCP4747X and restart it. Hope you can figure it out.

Thanks,

George

OK, I will look into this when I am back in my cockpit.

If you can provide more detail info about your MCP setting when this occurs it would help me dig further into this.

Also take a look at the OC.log in SIOC folder after the crash.

If there is any other users that have the same issue, please report them here.

I need to know it it a general issue or just a ONE user issue.

There are 2 things you should do if you are having crashes with the OCP4747X driver:

1. Change your IOCP port from 8092 to 8094 in order to avoid conflict with other application that uses the same port.


Change from IOCP port 8092 to 8094 in OC4BA.ini file.

Delete any PMDG xxxx.ini files in SIOC folder

Reset SIOC.exe in OC4BAv4/Config

Rerun configuration setup in OC4BAv4/Config

2. Update OCP4747X driver to version 4.1 by clicking "Check 4 Updates" in OC4BAV4 main window.



I have updated the OCP4747X driver. Update from OC4BAv4 "Check 4 Updates"

Hi Roar,

I was climbing from FL260 to FL350. I rotated the altitude knob clockwise, but the numbers started decreasing instead of increasing again. I tried it several times, but I could only get the altitude to decrease and not increase. Last time this occurred the OCP4747X program crashed. This time it didn't, but the only way to SET FL350 was to increase the altitude on the software MCP. I will send you a video if it helps.

Thanks,

Hi, I am aware of this issue from another user who had the same problem.

An easy fix is to change the script for the MCP like this:

---------------------------------
You could try to change the value 500 to 1500

In this line

&Delta_ALT = LIMIT 0 ,500 ,L0



Go to Edit Script in SIOC.exe and find the line , change it and save

And then test and report back.


I will update the official OCP4747X script file later this week.
