Hi These issues occured using a Raspberry Pi 4. I also repeated the experiment with codesys control for Windows, which results in much lower cycle times. With up to 3 ms, I still think they are fairly high given they should run at 2 ms and don't require complicated kinematics. The effect of higher cycle times for slower movements also prevails.

Post by nathant on Saving variable values on power cycle (RevPi Connect) ^{CODESYS Forge talk (Post)}
Hello, this seems to be a known issue, but persistent/retain variables don't seem to work properly on RevPi devices. Is there a workaround to this? All I need is for a few configuration variables to be remembered through power cycle.

I have EtherCAT servo drive lost communication with PLC everytime it gets faulted, it does not not communicate until I power cycle everything again, how to solve this issue?

Post by banialuk on CAN Open Manager - varible of SYNC ^{CODESYS Forge talk (Post)}
Hello, were I have find varaible of SYNC "Cycle Period" , or variable that informs about the start of a new cycle SYNC. I want to use this variable in program code. I need to for communication beetween Mster and slave, and send PDO informations.

Post by aikapan on Ethernet/IP Scanner Exception ^{CODESYS Forge talk (Post)}
Same here. plcload in my case is about 7% while running. Watchdog ENIPScannerIOTask was about 200ms. Max cycle around 6ms, normal cycle time 4ms. Probably just increase the watchdog to 2000ms? or so... (Hardware: A Panel from Weintek)

Have you tried using the persistence manager which uses the file system of the controller to store persistent variables?

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.

Post by manuknecht on High Cycle Times for SoftMotion_PlanningTask when using AxisGroup ^{CODESYS Forge talk (Post)}
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 fmon on Modbus TCP client reconnection problem ^{CODESYS Forge talk (Post)}
Problem solved The client modbus cycle time was linked to a task at 500ms. Whereas the channel modbus was at 200ms. Certainly problem of packages synchronisation. I let the client modbus cycle time to be handled by itself (See attachement) --> "Use the bus cyle time parameters" (traduce from french) See attachement
