in Developer Tools
We are using Pickmaster for our pick and place operation. The pattern selection needs to be done fron a PC application developed using PC SDK. I am trying to write to the variables of Pickmaster for performing the pattern selection but the controller gives exception.

code snippet:



Dim sig As IOSystemDomain.Signal = robctrl.IOSystem.GetSignal("pmOutfeeder1_giProdSel")

Dim gSig As IOSystemDomain.GroupSignal = DirectCast(sig, IOSystemDomain.GroupSignal)

gSig.WriteGroupValue(1)





Error:     "Write of unblocked in-signal not allowed."



please let me know how to do this.
