6 Commands
6.1 Command groups
Each command has a unique number. The triggering of a command occurs by
means of the sending of DR 11 (channel 1) or DR 12 (channel 2) and can be done
via various ports (SIMATIC, SIWATOOL U).
After each command transfer to SIWAREX U, it must be tested whether the
command was executed correctly. The reported data and command errors
(synchronous errors, see Chapter
) give information on why a command could
not be executed.
After the receipt of a command, SIWAREX U checks whether the command can be
executed. If the check turns out negative, you will be notified of the output of a
"synchronous" message about the cause (see Chapter
).
