Post by sturmghost on Find visualization elements that require a lot of computing time ^{CODESYS Forge talk (Post)}
I found out that the Codesys simulation mode is not good to measure performance. As soon as I upload the code onto the hardware PLC I can see that my visu-task needs around 60 ms to complete. I'm wondering if there is a possibility to find out which visualization/visualization element takes a lot of computing time? Then I would look for ways to decrease the long computing time.

Post by swe-hob on call of a method of a function block in another program ^{CODESYS Forge talk (Post)}
Hi, Let's assume following: PRG_1 fb_1 : fbExample1; fb_1.method_1 do something... PRG_2 fb_2 : fbExample2; fb_2.method_2 if xTest then PRG_1.fb_1.method_1(); end_if; Is there a reason why runtime hangs when I call the method_1 in PRG_1 from a method in PRG_2? Both programs run in the same task. No chance that any other program calls the method. What I practically do there is that in the program PRG_2 I add a structed object into a buffer. In PRG_1 I just process the items in the buffer.

Post by opineiro on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
Hi, I have an issue with a function which sends a message through API Rest. I'm using a function from httpCLient library. I have tested this function inside a program and it works fine. But when I want to use it inside a function (so I can call it simultaneously from 2 different points on the main program) it gives a stack overflow error. In detail it says: "C0297 Stack Overflow on Main Task. Stack sizes... Call hierarchy:" I have simplified as much as I can the function, but I'm hitting a wall with this. Anybody has an idea of what's wrong? Thanks!

Post by vformanek on irq-set piority is not working in plc-shell ^{CODESYS Forge talk (Post)}
Hello, I am currently having issues on CODESYS Control for linux SL with DTH expiring. I have followed several tutorials of creating a proper RT linux. Then I further configured the linux based on this tutorial: https://content.helpme-codesys.com/en/CODESYS%20Control/_rtsl_performance_optimization.html Currently I am getting DHT expires in the communication and I am trying to increase of the priority of the network task which manages the PROFINET network adapter. I am following this tutorial: https://content.helpme-codesys.com/en/CODESYS%20PROFINET/_pnio_trouble_connection_failure.html But the irq-set is not changing the priority. See the image bellow....

Post by timvh on CODESYS V3.5 SP15 Patch 2 won't open ^{CODESYS Forge talk (Post)}
This is almost always related to previously working with an additonal monitor. If you have placed CODESYS on that monitor, later start your laptop again and open CODESYS without that monitor, then Windows still places it in the previous position, but then it is not visible. So the solution by cehermanstad can be used to move it to the main screen to make it visible again. PS, another way to move it, is by pressing SHIFT and then right-click on the icon in the task bar, then select move. You can then move it with the arrow keys or your mouse.

Post by zoronoa on J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup ^{CODESYS Forge talk (Post)}
Hi, I'm trying to monitor a specific PGN which I have it sending a pulse every 500mS Problem: Using the Watchdog for the ECU does not really help me as I have multiple instances with separate PGNs, if a PGN goes ghost, the ECU watchdog won't be flagged as the others will be running. I found the J1939.ReceiveWatchdog & J1939.ReceiveParameterGroup function blocks and they seem like a good solution for my problem, I just can't get them to work from my understanding you just build the J1939.ReceiveParameterGroup once and then connect it's output to the J1939.ReceiveWatchdog, here's my CODE for the setup HEARTBEAT_TIMER(IN:= TRUE, PT:= T#1000MS); //turn-on delay because of initialization race IF HEARTBEAT_TIMER.Q= TRUE THEN Glob_Var.DisplayReceive.xExecute:= TRUE; Glob_Var.DisplayReceive.itfECU:= Valve_X; Glob_Var.DisplayReceive.dwPGN:= 65511; Glob_Var.DisplayWatchdog.xEnable:= TRUE; Glob_Var.DisplayWatchdog.itfParameterGroup:= Glob_Var.DisplayReceive.itfParameterGroup; Glob_Var.DisplayWatchdog.tTimeout:= T#1500MS; END_IF Notes: Glob_Var.DisplayReceive is of type J1939.ReceiveParameterGroup Glob_Var.DisplayWatchdog is of type J1939.ReceiveWatchdog The above code is done once and not cyclically I'm monitoring Glob_Var.DisplayWatchdog.xError cyclically
