Let us now take a look at the following parallel circuit consisting of two switches.
Circuit diagram
The corresponding circuit diagram
Translated into a xLogic circuit program this means: Relay K1 is (at output Q1) is controlled by
means of an OR block.
Circuit program
S1 is connected to the I1 and S2 to the I2 input connector of the OR block.
The corresponding layout of the circuit program in xLogic:
