to pop up its description (if any).
An instance of this Service Interface Function Block (SIFB) type
implements the fbmgt2 management scheme defined in
subclause 6.5 of the Compliance Profile
for Feasibility Demonstrations. Its service sequences are the same
as for the DEV_MGR SIFB
type. However, its RQST input and RESP
output are of types MGT_REQ
and MGT_RSP, respectively,
which lend themselves to more efficient encodings than the STRING
-encoded XML RQST input and RESP output of
the DEV_MGR SIFB type. Additionally, the USTRING type of this SIFB type's
DST input provides just as efficient an encoding for the
7-bit US-ASCII character set as the STRING type of the
corresponding input of the DEV_MGR type, while retaining
the ability to encode multi-byte character sets.
An instance of this type is automatically substituted for an instance
of the DEV_MGR type as the MGR block of a DM_KRNL instance when the MGR_ID
of the enclosing remote Device, e.g., an instance of RMT_DEV or FRAME_DEVICE,
specifies the fbmgt2 protocol, e.g., MGR_ID
:= "fbmgt2://192.168.2.1:61499" .
