Also I have HMI Internal bool TAG named (Sanit), how could I resetbit of this (Sanit) TAG by PLC bool TAG named (Sanit_Reset). Thank you.

Anyway, if you still think, that you want it to be that way, then create a vb script: Sub VBFunction_1(ByVal aSet) If aSet Then If SmartTags("THA_Steri_Set") Then SetBit"Steri" End If Else If SmartTags("THA_Sanit_Reset") Then ResetBit"Sanit" End If End If End Sub In the tags THA_Steri_Set value change event add the script with a value 1. In the tags THA_Sanit_Reset value change event add this same script with a value 0.
