NAND Gate
Combines two or more inputs to generate a single output.  The default 
is two inputs but by right clicking on a NAND gate to display the menu 
additional inputs can be added.  Unused inputs will default to the 
TRUE state.  The output is only true if at least one input is false.  The 
NAND gate adds a 25ms processing delay.

BUFFER Element
Used between a crosspoint trigger and a crosspoint action to reduce 
the system resource usage.  There is a constraint on the maximum 
number of possible actions by crosspoint triggers and crosspoint 
actions imposed by system resources.  In general the number of 
possible triggers times the number of possible actions should not 
exceed 4095.  So if there are 16 possible triggers specified in a 
crosspoint trigger and 16 possible crosspoint actions specified in a 
crosspoint action the number of actions would be:
16 triggers x 16 actions = 256 events
which would be acceptable.  If the result of setting up a system of 
crosspoint triggers and crosspoint actions created more than 4095 
possible actions an error would be reported when the configuration 
was downloaded.
In this case a buffer logic element should be placed between the 
crosspoint trigger and crosspoint action.  In this way the number of 
actions the trigger crosspoint has to make is limited to the number of 
trigger crosspoints, which only have to trigger the buffer.  The buffer 
will then act on the crosspoints in the crosspoint action.  
The BUFFER element adds a 25ms processing delay.

NOT Element
A NOT element inverts the input so that when the input is OFF the 
output is ON; when the input is ON the output is OFF.  The NOT 
function adds a 25ms processing delay.
