Signal descriptions
An overview of possible parameter assignments is provided on page 5-6, ”Possible parameter
assignments”.
ST Start signal
T-NR Tool number of the tool to be searched for
(optional)
DUNR Duplo No. of the tool to be searched for
(optional and only in connection with the T No.)
MAGA Number of the magazine, from where the tool is searched for.
MAGE Number of the last magazine where the tool is searched for.
PLAA Magazine location where the search starts.
This applies to all magazines specified in the parameters MAGA und MAGE. If the
magazine specified is a chain magazine, the specifications of the start and end of the

PLAE Last magazine location where the tool is searched for.
Marginal conditions as described under PLAA.
SURI Search direction
In this parameter, the direction in which the magazine(s) and the locations selected
is/are searched is to be specified. The search directions ”Forwards”, ”Backwards”
and ”Symmetrical” are available. Symmetrical search is only possible for chain
magazines (MD bit 11 = 1). If the parameter has a blank as default, the search
direction entered in machine data bit No. 10 of the respective magazine is used. If an
error is detected in the parameter assignment, the "Forwards" search direction is
defined automatically.

operation.

the case of a conditional call, the signal remains in the "1" state until the next search
job is initiated).
