Post by simotion on Pointer to Softmotion axis CODESYS Forge talk (Post)
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?

Post by r-niedermayer on C0564 Warning Message CODESYS Forge talk (Post)
Please see or Online Help on how to initialize variable before using them: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_pragma_attribute_global_init_slot.html Regarding the Attribute global_init_slot: You can use this pragma to influence the order in which signatures are processed during global initialization. It can only be applied to signatures. By default, the initialization sequence for variables from global variable lists is undefined! However, if, for example, variables from one list depend on variables from another list, it is necessary to initialize one before the other. (Aee OLH and Syntax) The placeholder <slot> must be replaced by an integer value that defines the position in the initialization sequence.</slot> The default value is 50000. A lower value causes an earlier initialization! If several signatures have the same value for the 'global_init_slot' attribute, the order of their initialization remains undefined! Cautious application should therefore be considered! Example: The project contains f.e. two global variable lists GVL_1 and GVL_2. The global variable "A" is part of the global variable list GVL_1: {attribute 'global_init_slot' := '300'} VAR_GLOBAL A : INT:=1000; END_VAR The initialization values of the variables "B" and "C" of GVL_2 are dependent on the variable "A". {attribute 'global_init_slot' := '350'} VAR_GLOBAL B : INT:=A+1; C : INT:=A-1; END_VAR So if you set the 'global_init_slot' attribute of the global variable list GVL_1 to 300, i.e. to the lowest initialization value in the example, then it is ensured that the expression "A+1" is well-defined at the time of initialization of "B".

Post by ofey on Symbol configuration / GVL CODESYS Forge talk (Post)
Hi! I have som variables that I communicate to a Modbus Master. These variables are declared in a "Global Variable List" where I have assigned them memory addresses. To organize this mapping I want to make a MODBUS list where I show all the variable names together with the memory address. Is there an easy way to export this list from CODESYS? Either through script or some export function maybe?
