AdvancedCMD

With the "AdvancedCmd" block, every command can be executed including commands not
represented by other blocks. This general structure can be used for all commands and is
intended only for trained users.
This gives you the option of sending the command as a chained command. To allow this, the
block provides a CMD buffer for 100 commands. All chained commands must be entered
starting at the first position in the buffer. For every chained command, the "chained bit" must
also be set in the CMD structure. The "chained bit" is not set in the last command in the
chain. You will find further information on the "chained bit" in the section "Chaining
(Page 105)".
The entire command structure must be specified in the "CMD" input parameter. You create
the structure for the "CMD" parameter in a data block.
