Rules Example
Until a new object is called up, the old object remains in
force. Entry of a different dialog lan-
guage: "deutsch"
New objects can be addressed relative to the old object:
A leading point leads one node forwards in the tree.
From the root to the node 'Aux':
&C.A
Forwards from the node 'Aux' to
'Prog': .P
More than one leading point leads one node backwards
in the tree. n nodes backwards require n+1 leading points. Jump from node 'Prog' to the
node 'Aux' and selection of the
new object 'Dialog' at this
node: ..D
To return to the root, enter a leading '&'. Switch from node 'Dialog' via
the root to node 'Parameter':
&P
6.1.3 Triggers
Triggers initiate an action at the 732 IC Detector, e.g. sequence start or
data transmission. Triggers are marked by the introducer '$' .
The following triggers are possible:
$G Go Starts processes, e.g. initiation of the auto-zero
function or program start
$S Stop Stops processes
$Q Query Used to request all information from the current
node in the tree forwards up to and including the
values
$Q.P Path Used to request the path from the root of the tree
up to the current node
$Q.H Highest
Index Used to request the number of daughter nodes of
the current node
$Q.N"i" Name Used to request the name of the daughter node
with index i, i = 1...n
$D Detail-Info Used to request detailed status information
$U qUit Used to terminate the data flow of the instrument,
e.g. after $Q
The triggers '$G' and '$S' are linked to particular objects, see Over-
view table in section 6.1.6.
All other triggers can always be used at all locations in the data tree.
Examples:
Request of the baud rate value:
&Config.RSset.Baud $Q
Request of all values of the node 'RSset' : &Config.RSset $Q
Request of the path of the node 'RSset' : &Config.RSset $Q.P
Triggering the auto-zero function: &Zero $G
Request of the detailed status: $D
