Hi All Not sure what im missing here but i seem to have a lot of issues when i start a project say at home then try to open it at work the next day on another pc, using same version of Codesys. I try the build option when opening the project but still get loads of placeholder,library and some random errors i'm not to sure about. have tied project Archive, which is better, but not perfect. Can someone tell me what im doing wrong!. Cheers

HI I have had a project running for a few weeks and twice it has shut the program down due to this exception. exception[ProcessorLoadWatchdog] occurred in: App=[all], Task[all] I have to reboot (power cycle) the system to clear the exception. or remotely restart the application. Any ideas? Cheers

I had the FB called via a for loop to call a few instances of my FB I have removed it the for loop and just called them 1 by 1. Seems to have sorted the problem. tho, i have other FB's and for loops doing the same thing but they are all fine. below is basically what was happening. var: mVibrator : ARRAY[1..GVL_Settings.Number_Of_Products] OF Main_Vibrator; end_var Controller(PRG) call: FOR v := 1 TO GVL_Settings.Number_Of_Products BY 1 DO; mVibrator[v] (); END_FOR So at state 30: the mVibrator[1].start...

pretty sure its not. ive done a cross reference and only have one write that sets it to true. Only way i can stop it is to remove the function block call from the main pou that is running said case. its got me stumped:/

I have a case statement running a process. during one of the steps it has started calling a bool var that is 2 steps further on in the case? i have even tried //commenting it out but it still turns on at the same point in the case. i have also run a trace but cant see anything that would trigger it. Any Ideas? Cheers

have been testing a program then out of the blue I start getting iodrvethernet errors ( using modbus tcp ) that was with latest version. I downloaded an older version of codesys, that I had used before with no errors. and used version 3.5.17 of the ethernet adapter. That worked fine for a day. then same thing. anyone have any ideas? I feel like some days I spend more time trying to sort out library issues then writing code.

I have a small program i would like to run 3 instances of on one plc. whats the best way to go about this? I was thinking about turning the program POU's(there are 4) into FB's... then call them 3x in a main POU and assign the i/o. But it just seems a bit messy... cheers

Hi Is there a way to display the project file name (string) so i can have it displayed on the HMI/PLC. So i know what version of the program has been uploaded. Cheers
