Relay TurnOn and TurnOff to one of many destinations. ScriptParams links with the data set to an integer index identify the destinations. Initially, the link index 0 is triggered. The index can be changed manually by sending a Validate message. If the parameter order is set to increment, the index is changed after each relay. Parameters increment and rollover control how the index is incremented. Setting the parameter order to step is like increment except when using rollover and increment is greater than 1. When the increment passes the rollover it will continue skipping values from 0. For example, 3 links with increment by 2 will go 0,2,0,2,0,2 when using increment, and 0,2,1,0,2,1 with step.
