Refresh - method of object PmCommData
Enables reading (restoring) all values of the data group defined on the Data
page together with the data registered into this object via the ExtComm
Refresh As Boolean
true - on success
false - on error
method is an asynchronous operation, i.e. after the method is terminated the data are not necessarily updated. The method only causes the data transmission and after completed, the onDataReceive
event is called.
The Refresh method need not to be called if the configurator Data refresh enabled is set, because the data are read automatically. The method can be alled even if the configurator is set - then this method alters the period of automatic transmission and one transmission is executed immediately.
This method can even be called from the INFO system
by clicking the "Actions
" button. See permission PmRoot > Permissions > InfoEdit
