65 SVALVE:OPEN
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 31), then the
parameters of scenario 1 are chosen. If the select pins are activated (see
paragraph 7.8, page 64), 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:OPEN
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:

66 SVALVE:OPEN:<RI>,<OT>,<FA>,<NL>,<NP>,<DL>
Description:
This command initiates a dispensing cycle with the parameter combination
currently selected. Time parameters have to be specified in 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” are not erased.
The values entered by “SVALVE:OPEN:<RI>,<OT>,<FA>,<NL>,<NP>,<DL>”,
are valid only until the end of the dispensing cycle. If you intend to use the
combination several times, the complete command has to be repeated at
the beginning of each single cycle. In such a situation it would be more
practical to use the “TRIGGER:SET” command instead, since the cycle in this
case can be reactivated simply by “SVALVE:OPEN”.
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:OPEN: 30,10,15,90,20,8
Result:
The dispensing cycle contains the following values:
Rising: 30 ≙ 3.0 ms (ms = Millisecond)
Open Time: 10 ≙ 1.0 ms
Falling: 15 ≙ 1.5 ms
Needle Lift: 90 %
Number of Pulses: 20
Delay: 8 ≙ 0.8 ms

67 SVALVE:OPENS<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:OPENS2
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:OPENS2
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).

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.
