2.4 Configuration limits and performance data
2.4.1 General characteristic data
Total number of freely usable connections on Industrial
Ethernet
118
The value applies to the total number of connections of the
following types:
• S7 connections
• Connections for open communications services
• FTP (FTP client)
Note
Connection resources of the CPU
Depending on the CPU type, different numbers of connection
resources are available. The
number of connection resources is the decisive factor for the number of configurable
connections. This means that the values that can actually be achieved may be lower than
specified in this section describing the CP.
Open User Communication (OUC) provides access to communication over TCP, ISO-on-
TCP, ISO transport and UDP connections.
