Error C0297 when trying to simulate PLC

2023-05-15T10:14:42.450000Z

Hi,

I am having the same issue when trying to add Mqtt libraries to my project. This message error appear only when generating code or simulating.

[ERROR] C0297: Stack overflow detected in MQTT_CONTROL (PLC_PRG()->HowTo()->MqttClient()->MQTT_CONTROL()->STRING_TO_URL())

Has anyone experienced something similar? It would be great if someone can help.
Many thanks,
Manuel

The problem appear only in simulation mode.

Someone solved this?

Not really. But i suspect this is only a problem with the simulation.

If you would like to run simulations i would probably just remove the canopen manager and test the program that way.

My setup is complicated to fully simulate so i will switch over to running from the actual PLC in mid August to fully test things.

I am experiencing the same issue - did either of you find a solution for this?

Hi, i seem to have an issue with canopen manager that causes an error when trying to simulate the PLC.

When i press download the compliation occurs as the attached txt file.

I recieve the error C0297 stack overflow that hinders me from downloading to the simulation PLC. If i remove the canopen manager i can download just fine to the simulation.

I have a licence for "CODESYS CANopen Manager SL" installed on the PC but this problem seems to persist.

I am running version 3.5 SP11.

Would be very grateful for som guidence where the problem for all of this could be located!
