to pop up its description (if any).
As shown above, an instance of this function block type contains an
instance of the DEV_MGR type
to provide device management services, and an instance of the SERVER_1_2 type to
provide remote access to those services.
In an instance of this FB type, the MGR block is
automatically switched to an instance of the DEV_MGR2 type if the MGR_ID
of the parent remote Device (e.g., an instance of RMT_DEV or RMT_FRAME) specifies the
fbmgt2 protocol, e.g., MGR_ID :=
"fbmgt2://192.168.2.1:61499" .
