If you use LTIME() you will be very accurate and be able to have a normal task cycle time.

Hi, you can call the decoder function block in a loop and/or decrease the task cycle interval of Task_PATH.

Hi, we did install the real-time kernel patch on the RPI and also performed the additional optimizations including isolating the cores. Changing the configuration of the planning task e.g. running it on a separate core, changing the cycle times and mode from cyclic to freewheeling did not show any improvements.

Post by acc00 on Main Task cycle too long leading to PLC Fail
CODESYS Forge

I have 2 Wago PFC200 PLC, running with Runtime SP19 Patch 5, with the Redundant application. The PLC communicates as Modbus Master with at this moment 15 Modbus Slaves -later there will be 28 in total- (Drives, Power management units,...). These devices are connected in 2 rings (1 ring of Drives, 1 ring of Power Management units), with 2 Managed Moxa Switches being part of the ring. Each PLC is connected to one of these switches. The issue I'm encountering is that the Cycle time of the Active PLC goes very high when I'm closing the Drive ring (simulating an issue on one Cabinet supply, resulting in that one Drive shut down, which can happen on field quite often). As a result of this long cycle, the PLC fails and goes to Exception, and the Passive PLC does not take control of the system. A normal cycle is around 30ms for the Main task, and a few ms for the Ethercat task. When I monitor with Profiler, I see that in this Maximum Cycle, the main Task is only taking 13ms, so I'm not sure where the PLC is hanging for so long. Is the remaining cycle time the Redundant management/sync or something else? Thank you in advance.

Hallo, wie verhält es sich mit der Demo-Version und Datenübertragung z.B. via CAN-Bus. Der Bus läuft, das Device befindet sich im Zustand "Operational" aber es werden keine Daten von der Soft-SPS empfangen. Ich benutze aktuell eine nicht lizenzierte Version von CoDeSys Control for Linux ARM64SL. Normalerweise sollte die Demo-Version uneingeschränkt laufen - also kann ich davon ausgehen, dass es sich um einen Programmierfehler handelt oder ist die Feldbusfunktion ohne Lizenz doch in irgendeiner Form eingeschränkt verfügbar (außer dem 30 Minuten Limit nach Reboot)?

CODESYS Forge

Meanwhile, I would like to understand why the motion FB instances must still be called even after the Execute is set to FALSE, especially in view of the fact that the next instruction is programmed to abort the previous one, with BufferMode set to 'Aborting'. All these unnecessary FB calls are an unnecessary overhead on the CPU anyway. Is there any precise rule about when to cease calling the various instances? (It should precisely be the 'done' status that says this one has finished its work). In general: - Motion function blocks have to be called until they report 'Done', 'Error', 'CommandAborted' or a subsequent motion FB with BufferMode=Aborting is started in the current cycle. - Setting the Execute input to FALSE will not abort any ongoing motion of the motion function block. For example, one case that is often problematic is the execution of the Axis Halt instruction. When, after a MoveAbosulte instruction this returns the event as 'done' and indeed the axis is in standstill, the state machine first sets the move instruction to FALSE, and the next cycle sets the Halt request to TRUE. Some of the time everything works out fine. Occasionally, however, in this exchange, the axis goes into fault, also losing the OPERATIONAL state. I think the error SMC_FB_WASNT_CALLED_DURING_MOTION is only a follow-up (and misleading) error that results from the axis not being in operational state anymore (bus problems). Is there an error 'regulator or start not set' in the device log before the error 'motion generating FB wasn't called for at least one cycle'? Which error does the respective function block (Halt.ErrorId) report?

Hi! I´ll try to get this thread going again as i´m having simliar problems. Right now i get a red triangle on my connected devices (i´m testing with a BME280 sensor and a PCA9685 resvo driver). The TCA9548 have the green symbol beside it. On the "red" devices i get that the bus is not running. I have tried to either run it using the parent bus cycle setting or creating a new freewheeling task prio 1 but nothing helps. I have compared my settings to the settings from the example from the MUX package and i have read (i think) every thread in forge that could be of interest. EDIT: The ic2detect only shows the mux (70-70) and the servo drive (70-76) so i´ll look in to if i managed to burn the 280-sensor while soldering). Another question regarding the 280 sensor. I have a sensor GY-BM E/P 280 that should record humidity and temperatur. Could this be a problem with the library? Does anyone have an idea of what i might be doing wrong? I have some experience from Codesys but not much so this could be an easy one. All suggestions are welcome. I tried to upload the project archive but it did not work. Should i upload the export or how could i show you my horrible project? Best, Martin

Hello dear colleagues. I have an ESTUN PRONET servo. I'm trying to control via softmotion over the CANopen bus. There is no Ethercat bus in this servo model. In another project,using Ethercat , I controlled four axes. I have problems with ESTUN PRONET servos. A DSP-402 driver mismatch is likely. I would be very grateful for your help in solving this problem.

Post by manuknecht on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup

Hello all I am using an AxisGroup with the Gantry2 Kinematics to move a 2D-Gantry system. When creating the AxisGroup, the SoftMotion_PlanningTask is created automatically with a cycle time of 2 ms in my case. I realized that the maximum cycle time of this task can spike to very high values (up to 60 ms) at lower speeds of the motion, leading to synchronization issues and errors on the axes. The same behaviour - though not as drastic - can be observed with virtual axes too. Is this behaviour intended or to be expected? Can the cycle time or type of the SoftMotion_PlanningTask be changed to prevent these errors? Or is there another fix for this issue? I tried changing the cycle type to Freewheeling, which solved the synchronization issues, but caused an error on the AxisGroup after a while, reading SMC_CP_QUEUE_UNDERRUN. Thanks in advance and best regards Manuel

I use fbMsSQL_compact(FUN) of the MySQL Library to write data to the database. There is no problem when writing data using only fbMsSQL_compact(FUN). However, when I try to write data obtained using SysProcessExecuteCommand2 to the database using fbMsSQL_compact(FUN), an error message "Dest server on ip address:xxx.xxx.xxx.xxx and port:1433 is unreachable" appears and writing is not possible. From what I have researched, it seems that writing is not completed in one cycle of fbMsSQL_compact(FUN), and when SysProcessExecuteCommand2 is executed first in the second cycle, the work done in one cycle of fbMsSQL_compact(FUN) is reset. Could you please give me some advice?

CODESYS Forge

I have noticed that a rm file1.txt command on a shell has an impact on the cycle time for a TASK writing to file2.txt. Seen in the Monitor fane of the Task configuration Furthermore if a TASK makes a system call like rm, its cycle time increases of course but it seems to have an invisible impact on other TASKs too. I have a TASK for handling communication over the CANbus (SPI) where it stops sending "Heartbeats" for many seconds when another TASK does a system rm. Why is that not seen on the Monitor fane? Is even codesyscontrol paused when system calls are made? The CPU load is about 30-40%

Thank you for your interest. Your answers are in line with what I knew, so at least it comforts me that I did not misinterpret the situation. However, I don't have an exact match as, for this project over the past few days I have: 1) I have gone back to leaving the various FBs of the motion always called, all of them, and in the state machine I use a boolean to activate the various useful Execute. (But in the future I want to go back and try the programming technique with which I wanted to develop this project); 2) For the occasional error: SMC_FB_WASNT_CALLED_DURING_MOTION perhaps it was due to the fact that I had set the Ethercat bus synchronism only at the CAN master level, but not at the level of individual drives. I have now also activated it for the individual drives and it does indeed seem to have been resolved, but having also adopted the programming technique mentioned in point 1), I cannot say whether this was the solution to the problem, or instead the previous point. Is there an error ‘regulator or start not set’ in the device log before the error ‘motion generating FB wasn't called for at least one cycle’? I can't answer that right now. By now the machine is running and I am no longer there, at this one. Also, I seem to remember that the 'fbeFBerror' drive structure (5-element array), does not cycle, BUT ONCE THE 5 EVENTS AFTER SWITCHING ON, IT DOES NOT UPDATE ANYMORE (but that's another issue), so diagnostics were not easy.

either you have "Insert with namespace" enabled in the SmartCoding options or your GVL_GLOBAL starts with {attribute 'qualified_only'} btw it's considered good practice to put the namespace in front of the variable. you could have variable with the same name in your PRG or FB.
