Is there a way to move the slave axis across the zero point of the master axis with variable start and stop points? For example: Slave start at 270Β° and end at 50Β°. thanks :)

I know, that is not the issue though. The issue is the HMI_Blower_Auto_PB variable not changing to false. I do not have the IO modules plugged in yet, that is why there are NaN values for those variables. That should not affect this.

I put the cross reference at the bottom of the pictures. It is not being written to elsewhere. I have tried the execute block too.

Hey mate, did you get to the bottom of this? If not, have you double checked the buttons are linked to the correct variables and/or performing the correct action? Have you tried always enabling the block to confirm false is moved to the variable if so?

Hello You'll need to write a proper sequence to send, then wait for confirmation, and then move on to the next step. Use the CASE statement in ST. It's perfect for creating a sequence.

You need to create a function around this function to check the dialogs you use in your program. That's the way i have done it.

Hello, I'd like to write some parameters to axes from inside a function block where I passed axis by reference, using ETC_CO_SdoWrite. Is it possible to get the device address from inside the function block? Please see example below. Thank you!

It's not that you missed something, it's that CODESYS doesn't have this feature. I hope CODESYS can add this feature. We also hope to add function overload functionality.

SysTimeRtcConvertUtcToLocal is marked as obsolete, but there's not hint on the actual implementation. Which function should I use instead? Edit: even the new online help is still using SysTimeRtcConvertUtcToLocal as example...

Memory addressing is measured in bytes, with BOOL occupying one byte. BIT is quite unique as it occupies one bit. So, try not to use BIT in the program. You can use the Unpack function to solve your problem.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
