4.4 Set parameters for the description of user-defined drives
4.4.1 Requirements
– The Motion Terminal boot procedure is completed.
–
A Motion App is not currently running on any valve (valve state ≠ "2" (running)).
– The option "Access to extended drive list" is set in the settings for the Motion Terminal. The setting
is made in the menu for the WebConfig interface or the transfer mode in channel 14 (
è
Tab. 59
Meaning of the indices per addressed target and channel)
– There is no simultaneous access to the parameters of the same user-defined drive via the transfer
mode of another valve or via the WebConfig interface.
After activation of the "Access to extended drive list" option, all Motion Apps can be selected and
used for drives that have not been tested or approved by Festo for the Motion Terminal or a specific
Motion App. The operation of Motion Apps using this option is therefore expressly outside the
specification.
4.4.2 Sequence
The following settings must be selected in transfer mode to transfer the parameters for the description
of user-defined drives:
– Operating mode of the valve (valve mode): 63 (transfer mode active) (PDO byte 0, bits 5 … 0 =>
111111
2
)
–
Channel (channel): 17 (parameterisation of user-defined peripherals) (PDO byte 1, bits 4 … 0 =>
10001
2
)
– Transfer control (transfer control): 1 (download) (PDO byte 1, bits 7 … 5 => 001
2
)
– Addressing of data transfer (addressed target): 101 … 108 (100 + number of the user-defined drive)
(PDO byte 2 => 101
10
… 108
10
)
–
Index (index): ID of the parameter for the description of user-defined drives that are to be set (PDO
byte 3 => 1
10
… 13
10
)
– Value (value): value that is to be written to the parameter (PDO bytes 5 … 4) (
