* The FCs AG_SEND and AG_RECV here can only be used for S7-300 (this
depends on release number of the CP, see the documentation for the CP).
** The FCs AG_LSEND and AG_LRECV here can generally be used for
S7-400, and in addition for S7-300 (this depends on release number of the
CP, see the documentation for the CP).
Special Feature: Connection to Broadcast and Multicast Nodes
For special connection types there is the option of selecting not just one connection
partner, but several ones (broadcast and multicast nodes). These options are
described in the SIMATIC NET (NCM S7) manuals. The connection partners "all
broadcast nodes" or "all multicast nodes" are listed in the dialog box for entering a
new connection.
• You can set up a connection to "all broadcast nodes" (simultaneous sending to
all broadcast receivers) for the connection types FDL connection and UDP
connection.
• You can set up a connection to "all multicast nodes" (simultaneous sending to
several nodes) for the connection types FDL connection and UDP connection.
