5.11.2.1 TCP-Connection
You may enter the TCP configuration via the interactive mask below. TCP is a connection oriented
protocol. TCP uses port numbers to address services on the application level. TCP provides reliable
end-to-end services. It also provides configurable performance improvements for slower long-
distance connections (PTT). The use of TCP is advisable where reliable data transfer services are
required.

Parameters for a TCP/IP-Connection
Connection name
You may specify a name for the connection. The name may consist of a maximum of 32
characters.
Frame offset (SSNR-Offset)
The frame offset (SSNR-offset) determines the frame from the start address that is used as
communication job by the current job. Frame offsets are normally only used in multi-
processor systems with values larger than zero.
Please use the following values when assigning frame offsets:
• Frame offset 0 for CPU 1
• Frame offset 1 for CPU 2
• Frame offset 2 for CPU 3
• Frame offset 3 for CPU 4
