Command Control Blocks (3000 to 3002)
Blocks 3000 to 3002 alter the command type field for a set of commands in the
client command lists. Block 3000 disables commands by setting the enable type
field to value of 0. Block 3001 enables commands by setting the enable type field
to a value of 1. The commands will be issued at the time interval no more
frequent than set in the poll interval parameter for the command. Block 3002 sets
the enable type field to a value of 2. This operation should only be used for write
functions as the command is only executed when the data referenced by the
command changes. The general format for the blocks is as follows:
Block Request
