It  is  possible  to  add  up  to  65535  blocks.    The  update  rate  decreases  as  the  number  of
blocks goes up.  For 25 blocks we have an update rate of 25*RPI = 25*0.1 = 2.5 seconds.

You  can  restrict  the  upcount  to  a  certain  value,  e.g.2  by  changing  the  Preset  value  of  the
CTU element.

Very Important Note!

It is very important to only update all the data of the Output Image Tag once using a
Synchronous File Copy element. It is not permissible to update the block number into the
Output Image Tag and then the data as this will cause an asynchronous transfer of data.
