Post by ph0010421 on Task time too fast? ^{CODESYS Forge talk (Post)}
Hello I've made an FB which is a TCP server. It uses the excellent CAA NetServices library. If I have the FB in a task <4ms, then the RT crashes immediately at boot up. If the task >=4ms, it starts and runs perfectly. This is even if the block is not doing anything; just instantiated. Am I missing something silly? Why would a low task time cause this? 4ms is perfectly adequate, but I'm just interested why... thanks PH

Hi ducng, please make sure to call all Motion-FBs in the EtherCAT task. In your case, the PLC_PRG should be below the EtherCAT task, not the MainTask. Best regards, Georg

Took me a while to work on this again. I testes today with a fresh setup and it works now. My OneWireCycle tasks runs for around 10seconds. I guess my mistake was that I put the cycle task for the OneWire Task to a too small number. Thx for the support!

For anyone reading this after the fact, it seems my issue was Alarm Task Manager. Deleting it from my program fixed the issue.

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

Hi, Regarding tasks created in Codesys, are they designed to execute sequentially or independently like how an RTOS operates? Best regards.

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

Could you check the taskcycle time in the taskmonitor (online monitor) - do you really see this 1s on Ethercat Task? Need to check this on my hardware but will take some time...
