The ALGorithm command subsystem provides:

•

Definition of user defined control algorithms

•

Communication with algorithm array and scalar variables

•

Controls to enable or disable individual loop algorithms

•

Control of ratio of number of scan triggers per algorithm execution

•

Control of loop algorithm execution speed

•

Easy definition of algorithm data conversion functions

places values of <array_name> for algorithm <alg_name> into the Update Queue. 
This update is then pending until ALG:UPD is sent or an update event (as set by 
ALG:UPD:CHANNEL) occurs.

ALG:ARRAY places a variable update request in the Update Queue. 
Do not place more update requests in the Update Queue than are allowed by the 
current setting of ALG:UPD:WINDOW or a "Too many updates – send 
ALG:UPDATE command' error message will be generated.
