Connection of I-LB or other bridging modules:
Note: If I-LB (or other bridging module) is to monitor all the site, it is recommended to place it at the

not at all or only seldom, option 2 is more suitable. Remote connection to let’s say controller 7 is
possible in this case but data transfer will be quite slow.
