There are two methods :

• Using the SCADA verb “LNS(READCONFIGPROPERTY, NetworkAlias, NodeAlias);” for each Lonworks node
• Using the trick explained below

It is necessary to use the watch count variable:

The watch count is set to 1 in the following cases :

• If the variable is in permanent scan
• If the variable is used in the open mimic
• If the variable is present into an event action
• If the variable is present into an expression

UCPT and SCPT variables are refreshed if the watch count goes from 0 to 1. In your project, you must ensure that watch count is 0 and the variable is used in a single open mimic. When opening the mimic the watch count changes from 0 to 1 and the value is updated.
