Function
Indicating warnings
Bit 7 in byte 1 (PDI) will indicate if warnings are pending in the diagnostic memory of the Motion
Terminal.
Value Description
0 There are no warnings from the active Motion App.
1 The active Motion App is indicating a warning that is pending in the diagnostic memory of
the Motion Terminal.

3.5.3
Running a Motion App
The system and application parameters must be defined depending on the Motion App before opera-
tion (
è
3.4.3 Parameter). The Motion App uses the parameter values defined by the user and the
teach-in data from the active parameter set if necessary (
è
4.6 Changing an active parameter set). The
system and/or application parameters used by a Motion App are documented in the manual for that
Motion App.
3.5.3.1
Requirements
–
The Motion Terminal boot procedure is completed.
–
System and application parameters required by the Motion App have been transferred (
è
4.1
Setting system, application and tuning parameters).
– If the Motion App should access sensor data, the sensor parameters required for all assigned
sensor inputs have been transferred (
è
4.3 Setting sensor parameters).
–
If necessary, a teach-in run for the Motion App has been carried out (
è
3.7 Teach-in run).
– The status of the valve on which the Motion App is to be run is “ready” ("configurable") (
è
3.5.2.2
Structure of the input data (PDI)).
– There is no active or inactive error on the valve on which the Motion App is to be run (
è
3.8.3.5
Readout of a malfunction list;
è
3.8.3.6 Acknowledging errors and clearing the malfunction list).
3.5.3.2 Starting a Motion App
To start a Motion App, setpoint values 1 and 2 and the command (comprising "valve mode", "app
control" and "app option") must be transferred in the 6 byte PDO for the corresponding valve.
Example
Motion App #02 “Proportional directional control valve” (PDO byte 0, bits 5 … 0 => 2
10
) is to be started
with the following specifications:
–
Switching status of the air ports (app control):
(2) active, (4) active (PDO byte 0, bit 7 => 1, PDO byte 0, bit 6 => 1)
– Valve type (app option): 2 x 3/3 (PDO byte 1 => 15
10
)
– Degree of opening (2) (setpoint value 1): +50% (PDO byte 2+3 =>5000
10
)
–
Degree of opening (4) (setpoint value 2): +40% (PDO byte 4+5 =>4000
10
)
