4.2.5  Events – System automation 
A CZone/MasterBus device can be programmed to initiate an action at another connected device. This is 
very helpful in automation of your system but is not required. 
In MasterBus this is done by means of event-based commands. In the Events tab you can program the 
ChargeMaster  Plus  to  act  as  an  event  source.  Events  which  occur  during  the  operation  of  the 
ChargeMaster Plus will then trigger actions from other products. The following tables list the parameters 
as shown in MasterAdjust.
