Sequences are created in the submenus '
>start sequence'
, '
>sample
sequence
' and '
>final sequence'
; these can be accessed via the pa-
rameter menu (press
<PARAM>
).
A sequence is arranged in lines. If a command is entered a new line con-
taining this command will be appended to the line which is currently shown.
The line number can be seen in the display. 99 lines are possible per se-
quence.
A line is deleted by pressing
<DELETE>
. The following lines move up one
position.
A new line can be inserted at a later date by using
<INSERT>
. This inserts
an empty line before the line which is currently shown. The following lines
move down one position.
The commands which are available as a second function on the numeric
block of the keyboard can also be used in a command sequence. These
are almost the same commands which are used for manual operation.
However, in a sequence these may possess other or further selection pos-
sibilities.
During the course of a method it is possible to alter all entries in the '
con-
figuration
' and '
parameters
' menus. With a few exceptions (see page 23ff)
these alterations directly affect the course of the method.
Care should be taken in making alterations to the method sequences. These
can be edited "live" (including inserting or deleting a command line); how-
ever, the TRACE and LEARN functions are not available. It is therefore not
possible to test out the edited function. This means that it is easy to produce
illogical or critical command sequences which create an error situation and
compel a sample series to be aborted.
3.3.2 LEARN mode and TRACE function
As when editing a method it is easiest to determine the parameters of a
command interactively, i.e. by manual operation, certain commands are
"adaptive". When editing a sequence the LEARN mode makes it possible to
carry out particular sample changer commands by manual operation. In
this way the resulting parameter (e.g. the lift position or the status of the in-
put lines of the remote interface) can be included in the actual command
line. The LEARN function can be used repeatedly. If times or volumes are
"learned" then this means that the values will always be added together.
Procedure for creating methods:
•
Enter a command or select an existing command line
•
Press the
<LEARN / HOLD>
key
•
the function starts, the "LEARN"-LED lights up
•
press the
<LEARN / HOLD>
key
•
function is stopped, the "LEARN"-LED blinks
•
use the
<ENTER>
key to accept the value (or start the LEARN
function again)
•
The "LEARN"-LED goes out, edit the next command line
