## Logic microblocks Logic microblocks perform logical operations on their inputs. Often these microblocks determine the conditions that trigger equipment starts, stops, or alarms.
| And - 2 Input This microblock accepts 2 on or off (digital) signals. If both inputs are on, the output is on. If either of the 2 inputs is off, the output is off.
| And - 3 Input This microblock accepts 3 on or off (digital) signals. If all the inputs are on, the output is on. If any of the 3 inputs is off, the output is off.
| And - 4 Input This microblock accepts 4 on or off (digital) signals. If all the inputs are on, the output is on. If any of the 4 inputs is off, the output is off.
| And - 5 Input This microblock accepts 5 on or off (digital) signals. If all the inputs are on, the output is on. If any of the 5 inputs is off, the output is off.
| Or - 2 Input This microblock accepts 2 on or off (digital) signals. If either or both of the inputs are on, the microblock's output turns on. If neither of the 2 inputs are on, the microblock's output turns off.
| Or - 3 Input This microblock accepts 3 on or off (digital) signals. If any of the 3 inputs are on, the microblock's output turns on. If none of the inputs are on, the microblock's output turns off.
| Or - 4 Input This microblock accepts 4 on or off (digital) signals. If any of the 4 inputs are on, the microblock's output turns on. If none of the inputs are on, the microblock's output turns off.
| Or - 5 Input This microblock accepts 5 on or off (digital) signals. If any of the 5 inputs are on, the microblock's output turns on. If none of the inputs are on, the microblock's output turns off.
| Exclusive Or (XOR) This microblock accepts two on or off (digital) signals. If either of the two inputs are on (but not both), the microblock's output turns on. If none of the inputs are on, or if both of the inputs are on, the microblock's output turns off.
| Not This microblock produces an output opposite of its input.
