Note
If only one parameter is read, in the other parameter,
a ‘0’ (zero) must be specified as the number of the other
parameter (= ‘No.’, byte 7). An entry in IND (index) is
then ignored.
The attempt to read another parameter leads to an ex
ecution error (E3.xx).
The read command is executed as usual with the start
flag. Both gripper finger selection bits must be set here.
The command is ended when the HGPPI−... signals
Motion Complete" (MC).
If an actual value (parameter group 3) is read out, only
the current value at the time of the query is output.
There is no automatic refresh", if the displayed value
should change.
If no error occurs during processing, the HGPPI−... trans
fers the read values as a reply in the actual values.
If an error occurs during processing, the error number is
transferred instead of the value. At the same time, the
HGPPI−... goes into error status.
