• When input I0 and input I1 are both on, output Q0 turns on.
• When either input I1 or input I2 is on, output Q1 repeatedly turns on and off in a one second cycle.

Input I0 is inserted at the position of the mouse pointer.

Circuit block Input I0 Input I1 Input I2 Action
Q0 ON ON – Turn output Q0 on
Q1
– OFF ON
Repeatedly turn output Q2 on and off in a one

The output FB and all the FBs connected on the left side of that output FB's input connectors are called the
circuit block. The output value of the output FB is the execution result for a single circuit block.
