Shared device
Individual submodules of the CP as IO device can be assigned up to two PROFINET
IO controllers in STEP 7 V5.5.
Note the information on configuring PROFINET IO systems with shared IO devices in
the "PROFINET System Description", see references, /13/ (Page 74).
●
S7 communication and PG/OP communication with the following
functions:
–
PG functions (including routing)
–
Operator control and monitoring functions (HMI)
Multiplexing TD/OP connections
–
Client and server for data exchange via communication blocks on S7 connections
configured at both ends.
Note
Blocks for S7 communication (see also STEP 7 online help or the "System Software
for S7-300/400 System and Standard Functions" manual):
•
BSEND FB 12
•
BRCV FB 13
•
PUT FB 14
•
GET FB 15
•
USEND FB 8
•
URCV FB 9
•
C_CNTRL FC 62
–
Server for data exchange on S7 connections configured at one end only without
communication blocks on the S7300 / C7300 station
●
Open communication services with the following functions:
–
SEND/RECEIVE interface over ISO transport connections, ISOonTCP, TCP and UDP
connections
UDP frame buffering on the CP can be disabled during configuration. When
necessary, this allows you to achieve a shorter reaction time between the arrival of a
UDP frame and its evaluation on the CPU.
–
Multicast over UDP connection
The multicast mode is made possible by selecting a suitable IP address when
configuring connections.
–
FETCH/WRITE services (server; corresponding to S5 protocol) via ISO transport
connections, ISOonTCP connections and TCP connections;
The addressing mode can be configured for FETCH/WRITE access as S7 or S5
addressing mode.
–
LOCK/UNLOCK with FETCH/WRITE services;
–
Connection diagnostics from the user program
