Advancedcmd - Siemens SIMATIC Ident Function Manual

4.5.3.10

AdvancedCMD

Using the "AdvancedCmd" instruction, every command can be executed including
commands not represented by other instructions. This general structure can be used for all
commands and is intended only for trained users.
This instruction gives you the option of sending the command as a chained command. The
instruction provides a CMD buffer for 10 commands for this. 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 93)".
The entire command structure must be specified in the "CMD" input parameter. You create
the structure for the "CMD" parameter in a data block.
