Result:
The system launches a dispensing cycle, using the
parameters given by the working configuration, scenario 1
or the select pins, respectively (for further information
about scenarios and the select pins, see
paragraph 7.9,
page 66). Usually this is the working configuration (setup 0).
But if in the menu SCENARIO is ON (see paragraph 4.5.5,
page 31
), then the parameters of scenario 1 are chosen. If
the select pins are activated, the setup (or scenario) is
determined by them.
Return:
30,10,15,80,20,15
69 SVALVE:AOPEN:<RI>,<OT>,<FA>,<NL>,<NP>,<DL>
Description:
With this command, both of the parameters “Rising” and “Falling” are
specified in steps of 1/100 ms, in contrast to the other time parameters
(1/10 ms).
Specified values must be integer and positive. To choose the external
mode, enter “EXTERNAL” for “Open Time”, instead of a numerical value.
You have to include all six setup parameters.
Parameters previously entered by “TRIGGER:SET” or “TRIGGER:ASET” are not
erased, but the combination remains in the system only until the end of the
cycle. If you do not wish to reenter the entire command several times, the
“TRIGGER:ASET” command is advantageous. This way the cycle can be
reactivated simply by “SVALVE:AOPEN”.
This command works just like its “VALVE” variant. Only the MDC does not
answer with “OK”, but with the parameters, which were used to trigger.
This way the machine software can check the parameters directly.
Important Note!
In case you trigger a dispensing process in the Infinite Mode with this
command, you cannot stop it via the RS232C interface. You can only stop it
via the PLC interface or by pressing the [esc]-key on the MDC.
Example:
Input:
SVALVE:AOPEN: 30,10,15,90,20,8
Result:
The dispensing cycle contains the following values:
Rising: 30 ≙ 0,3 ms (ms = Millisecond)
Open Time: 10 ≙ 1,0 ms
Falling: 15 ≙ 0,15 ms
Needle Lift: 90 %
Number of Pulses: 20
Delay: 8 ≙ 0,8 ms
Return:
30,10,15,90,20,8

70 SVALVE:AOPENS<setup no.>
Description:
This command initiates a dispensing cycle with the parameter combination
of the setup (or scenario) indicated in the command.
You decide to dispense with the parameters of a specified setup (or
scenario, if SCENARIO is “ON”), by using one of the following command
extensions:
• S0 - uses parameters of setup 0 (or scenario 1 with SCENARIO „ON“)
• S1 - uses parameters of setup 1 (or scenario 2 with SCENARIO „ON“)
• S2 - uses parameters of setup 2 (or scenario 3 with SCENARIO „ON“)
• S3 - uses parameters of setup 3 (or scenario 4 with SCENARIO „ON“)
These parameters are used even with activated select pins. As an example,
to dispense with the parameters of setup 2 you have to enter the following
command:
SVALVE:AOPENS2
For this example, SCENARIO has to be “OFF” in the menu.
This command works just like its “VALVE” variant. Only the MDC does not
answer with “OK”, but with the parameters, which were used to trigger.
This way the machine software can check the parameters directly.
Important Note!
In case you trigger a dispensing process in the Infinite Mode with this
command, you cannot stop it via the RS232C interface. You can only stop it
via the PLC-interface or by pressing the [esc]-key on the MDC.
Example:
Input:
SVALVE:AOPENS2
Result:
The system launches a dispensing cycle, using the
parameters given by the selected setup (or scenario; for
further information about scenarios and the select pins, see
paragraph 7.9, page 66).
Return:
50,20,20,80,1,10

71 WRITE:LCD:<text> (LCD = Liquid-crystal display)
Description:
With this command, an ASCII text including up to 32 characters can be writ-
ten on the screen. All the letters appear in form of capital letters.
Example:
Input:
WRITE:LCD:Hello World
Result:
The display shows:
HELLO WORLD
Return:
OK
72 SCENARIO:STATUS
Description:
This command tells if scenarios are “ON” or “OFF”. It also gives this
information for the four PLC-Stops.
Example:
Input:
SCENARIO:STATUS
Result:
Gives the ON/OFF status for scenarios and the four PLC-
Stops.
Return:
Scenario: OFF
PLCSTOP Scenario 1: OFF
PLCSTOP Scenario 2: OFF
PLCSTOP Scenario 3: OFF
PLCSTOP Scenario 4: OFF
73 SCENARIO:OFF
Description:
This command deactivates the use of scenarios.
Example:
Input:
SCENARIO:OFF
Result:
Use of scenarios is deactivated.
Return:
OK
74 SCENARIO:ON
Description:
This command activates the use of scenarios.
Example:
Input:
SCENARIO:ON
Result:
Use of scenarios is activated.
Return:
OK
75 SCENARIO:PLCSTOP:<Scenario no.>:OFF
Description:
This command deactivates the PLC-Stop. The number of the scenario can
be either 1, 2, 3 or 4.
Example:
Input:
SCENARIO:PLCSTOP:1:OFF
Result:
PLC-Stop for scenario 1 is deactivated.
Return:
OK
76 SCENARIO:PLCSTOP:<Scenario no.>:ON
Description:
This command activates the PLC-Stop. The number of the scenario can be
either 1, 2, 3 or 4.
Example:
Input:
SCENARIO:PLCSTOP:1:ON
Result:
PLC-Stop for scenario 1 is activated.
Return:
OK
