56 SVALVE:AOPEN
Description:
This command initiates a dispensing cycle with the parameter combination
currently selected. Usually this is the working configuration (setup 0). But if
in the menu SCENARIO is ON (see
paragraph 4.5.5, page 35), then the
parameters of scenario 1 are chosen. If the select pins are activated (see
paragraph 7.8, page 68), the setup (or scenario) is determined by them.
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
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 70). Usually this is the working configuration (setup 0).
But if in the menu SCENARIO is ON (see paragraph 4.5.5,
page 35
), then the parameters of scenario 1 are chosen. If
the select pins are activated, the setup (or scenario) is
determined by them.

57 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: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: 30,10,15,80,20,15
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: 80 %
Number of Pulses: 20
Delay: 15 ≙ 1.5 ms
Return:
30,10,15,80,20,15
58 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
