3.2.10.5 SNMP communication service
Availability
The SNMP communication service is available for CPUs with integrated PROFINET
interface and Firmware 2.3.0 or higher.
Properties
SNMP (Simple Network Management Protocol)) is a standard protocol for TCP/IP networks.
Reference
For further information on the SNMP communication service and diagnostics with SNMP,
refer to the
PROFINET System Description.
3.3 3.3 S7 connections
3.3.1 S7 connection as communication path
An S7 connection is established when S7 modules communicate with one another. This S7
connection is the communication path.
Note
Global data communication, point-to-point connection, no S7 connections are required for
communication via PROFIBUS DP, PROFINET CBA, PROFINET IO, TCP/IP, ISO on TCP,
UDP and SNMP
Every communication link requires S7 connection resources on the CPU for the entire
duration of this connection.
Thus, every S7 CPU provides a specific number of S7 connection resources. These are
used by various communication services (PG/OP communication, S7 communication or S7
basic communication).
