LaxisCtrl - MasterAxis Selection

Hello all,

I have one question regarding LaxisCtrl library fo motion control.

I am using FB LaxisCtrl_SyncAxisCamming  and I want to put for "master input" diferent axis depending of the process so I decided to use type of data block DB_ANY

But I have constant Error " Temporary CPU error: Access error (data block type) DB 1010 in FB 2001".

DB 1010 is Position Axis which is written to DB_ANY db. When I put directly this DB as input for master, I have no problem.

When I write in this way : 

"virtMaster".MasterAxis := "realAxis"; where is "virtMaster".MasterAxis DB_ANY and then I put as input I have the error.

I have checked the type of "virtMaster".MasterAxis  : (IF TypeOfDB("virtMaster".MasterAxis) = TO_PositioningAxis THEN ) and the statement is true, so I really copy the real axis to virtmaster

I saw in some Siemens Examples that this kind of master selection is working with DB_ANY. 

Can somebody help me with this issue?

Thank you in advance, I hope I was clear enough with explaining the problem 

Hi,

take a look here: 

What are the advantages of using the data type DB_ANY with Motion Control applications?

In case you are using V16 a new version of LAxisCtrl has been released that is based on DB_ANY:
