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://" .
