hi jay
in my understanding of scplus, you do not have to use sc server as managed node, cause the scplus adapter is installed on the tmr server, and connects itself to the sc server, and just sends sc specific commands to sc.
if you install it only for tec use you just have to write your rules, if you need something special and reload them. but take care scplus do not work with 3.7.1, and in 3.7 you have to change the '..' in baroc files otherwise it will not work.
i think SC Server needs not to be managed node
i will check it exactly
hope this helps a little in meantime
ciao joe
