How to set all struct bits using indirect addresing

[plcnoob69]

Hi,
I have this code:

LAR1 P##structy
L 0
T LW [AR1,P#0.0]

which resets all the bits in this struct called structy. How could I do the opposite - activate all of them? I tries with L 1 instead of L 0 but it didn't work.

 

[L D[AR2P#0.0]]

Use -1
