In my projet I use Softmotion.
There are several Softmotion axis (type SM_Drive_Virtual).
In the Global Variable List I have an array of pointers to the adress of the Axis.
Axis : ARRAY[1..iMaxCntAxes] OF POINTER TO AXIS_REF_SM3 :=
ADR(AX01_Axis), // [1
ADR(AX02_Axis), // [2]
This works, but when compiling I get the message :
. [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX01_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior. [WARNING] E3D: GVL Device: PLC Logic: Application: C0564: A reference to uninitialized variable AX02_Axis is used for initialization of Axis. Accessing the uninitialized variable may result in unexpected behavior.
Is there a way when initializing to force the hardware (softmotion axis) to first initialize and then the Global Variable List?

No ideas?
I get the same warning message with initialized variable.

Hi, you can take a look at https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_global_init_slot.html
Maybe it helps.
