Parameter instances 513-524 are for the Group feature. There are four groups
with three parameters per group. The first parameter specifies the slave nodes
that are members of the Group. The second parameter specifies the Relay
Object instances that are inputs for the Group’s trigger. The third parameter
determines whether any or all of the Relay inputs must be activated in order
for a Group trigger to occur. When the Group trigger occurs, a trigger event is
sent to all of the member nodes.
