warning
  • OR is an extensible function, and inputs can be added by clicking the "+" in the graph
  • IN1...INn data types need to be consistent and the same as OUT
  • ANY_BIT data types include BYTE, WORD, DWORD, and LWORD

Example​

Perform an "OR" operation on bit 0 of the value input to IN1 and bit 0 of the value input to IN2. The result is stored in bit 0 of the output OUT. Performs the same logical operation on all bits of the specified variable. As shown in the figure below, the result of 15 "or" 36 is 47
