Parameterisation
In this chapter, parameterisation refers to the transfer of system, application and tuning parameters
from the higher-order controller (PLC) to the Motion Terminal VTEM.
The transfer mode of the Motion Terminal is used to transfer the parameter values (
è
3.5.4 Transfer
mode).
In addition to the approach described here, it is also possible to set up the parameters of the
Motion Terminal using the WebConfig user interface or to import them from a previously exported
configuration file (
è
3.3.3 Export/import of parameterisation and settings).
Parameterisation that has been created using the WebConfig interface and saved on the Motion
Terminal controller can be transferred to the higher-order controller via a read-out in transfer mode.
4.1 Setting system, application and tuning parameters
System, application and tuning parameters are set using the transfer mode (
è
3.5.4 Transfer mode).
4.1.1
Requirements
–
The Motion Terminal boot procedure is completed.
– There are no Motion Apps currently running on the valve in question (valve state ≠ "2" (running)).
4.1.2
Sequence
To transfer system, application and tuning parameters, the following settings must be selected in the
transfer mode:
– Operating mode of the valve (valve mode): 63 (transfer mode active) (PDO byte 0, bits 5 … 0 =>
111111
2
)
–
Channel (channel): 1 … 5 (ID of the parameter set for which the parameters are to be defined) (PDO
byte 1, bits 4 … 0 => 00001
2
… 00101
2
)
– Transfer control (transfer control): 1 (download) (PDO byte 1, bits 7 … 5 => 001
2
)
– Addressing of data transfer (addressed target): 0 … 60 (PDO byte 2 => 0
10
… 60
10
)
– 0 for setting system parameters that are independent of the Motion App. In this case, compliance
with value ranges that are specific to the Motion App is not checked.
–
1 … 59 for setting system, application or tuning parameters for the corresponding Motion App
– 60 for setting parameters for the teach-in run
è
3.7.1 Prerequisites for starting the teach-in run
– Index (index): ID of the parameter to be set (PDO byte 3 => 12
10
… 255
10
)
–
Value (value): value to be written to the parameter (PDO bytes 5 … 4)
è
3.4.3 Parameter.
