JeffLowe Posted February 2, 2022 Share Posted February 2, 2022 For many years now we have been operating our 460 UMAC with Phase/Servo/RTI at 16/8/4 KHz with near flawless operation. Admittedly, on some certain complex part programs the 460 will throw an insufficient calculation time error. Since implementing the Quad core, the same settings have worked well and have eliminated all instances of insufficient calculation time errors. However in trying to increase performance I have increased the clocks to 32/16/8, but I now get a burst of errors on startup. These can be cleared and the system almost works, however opening the IDE (18.104.22.168) the machine crashes hard with Phase/Servo/RTI errors. Looking at task manager does not show any undue CPU utilization (I am running "Balanced"). Dropping down to 24/12/6 does not resolve this. It seems that the communications tasks are preempting the real time tasks and I do not understand this. I do note the ps -a command shows a bunch of gpascii sessions. Also, when opening or closing the apps within the IDE (Tuning/Plot/Watch) generates bursts of errors. Is there anything I can do to make the hard real time tasks more robust so that they are not preempted by the IDE? (FW is 2.6.0.,1) Quote Link to comment Share on other sites More sharing options...
