3.5.3.6 Standby mode of a Motion App after an error has occurred
If an error occurs during execution of a Motion App, the status of the valve (valve state) changes to
the value "3" (failure). The active operation of the running Motion App is stopped and the valve is
switched to the safe state. As soon as the cause of the error has been remedied and the error is no
longer active, the valve automatically switches to status "0" (not ready). In the event of errors that
were caused by the execution of the Motion App itself, the cause is already cleared by the implicit
stop.
The Motion App remains in standby mode as long as the higher-order controller continues to transmit
the ID of the previously running Motion App as the operating mode of the valve (valve mode). In
this case, no further actuating signals are generated for the valve. The valve outputs remain closed.
However, the actual values defined for this Motion App are still determined and output in the process
data. The standby mode can be ended via the operating mode (valve mode) 61

Motion App.
In the two statuses "3" (failure) and "0" (not ready), it is possible to switch to the transfer mode, for
example to read out the malfunction list
è
3.5.4 Transfer mode. After exiting the transfer mode, no
further execution of the Motion App in standby mode is possible.
The valve status "0" (not ready) can be acknowledged as usual by the operating mode (valve mode)

3.8.3.6 Acknowledging errors and clearing the malfunction list. The valve returns to operating
mode (valve mode) 61 with valve status "1" (configurable). The standby mode may then be termi-
nated. The valve is ready for operation again for a Motion App.
3.5.4 Transfer mode
The transfer mode (valve mode (valve mode)= “63”) has the option of exchanging information such
as parameters (

channel in transfer mode) between the Motion Terminal and the higher-order controller using a range
of channels. The transfer mode makes use of process data (6 bytes output data (PDO) and 6 bytes
input data (PDI) for each valve).
3.5.4.1 Structure of the process data in transfer mode
Structure of the output data (PDO)
During operation of the transfer mode the 6 bytes of output data (PDO) per valve slot are divided into
3 sections:
