 +==== bit index ====
 +
 +In the bit index, MSB is a large value and LSB is 0. For example 16 bit valus's bit index is
 +
 +| 15 | 14 | 13 | 12 | 11 | 10 | 9 | 8 | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
 +| MSB | |||||||||||||| LSB |
 +
 +===== Expressions =====
 +
 +The lamp's state can be determined dynamically though an expression.  If the expression evaluates to 0, the lamp is off.  If the expression evaluates to anything non-zero, the lamp is on.

 +To have the lamp blink, select the "Blink when ON" checkbox.
