Customizing Open
OpenÕs Hooks
Using the LI-6400
26-9
Example #1: Using New MeasurementÕs Fct Keys
“LI-610 Fct Key”
, and illustrates how hooks can be
used to define function keys in OpenÕs New Measurements mode. The task at
hand is to provide a function key in New Measurements mode that will set a
D/A channel for controlling an LI-610 Dew Point Generator. The function
key will be on level 7 (which normally has 5 blank keys).
You can try this out by selecting
Config Menu
®
"Installation Menu"
®
"Configuration Examples Menu"
®
"LI-610 Fct Key Control"
. This will
install a new configuration, and if you switch to it (
"Reset to User
Config"
), youÕll see the new key in New Measurements mode, level 7.
Discussion
We accomplish this task by using two hooks:
DefUserKeys
is the most impor-
tant, since that is how weÕll get our key defined. The other hook,
UserNM-
Figure 26-1. The file Ò/User/Configs/Modules/LI-610 Fct KeyÓ. It uses two hooks by defining the functions
DefUserKeys
, and
UserNMStartUp
.
