The register addresses shows the relevant local and partner address
information as suggestion values. Depending on the communication type
you may leave the address information unspecified.
The following table shows the combination options with the different
operating modes:

A connection is specified by the local and partner connection end point. At
the project engineering of connections ports/TSAPs must be congruent
crosswise. Depending on the protocol the following parameters define a
connection end point:
IP address Station A IP address Station B
partner TSAP → → local TSAP
local TSAP ←
ISO-on-TCP
connection
← partner TSAP
IP address Station A IP address Station B
partner Port → → local Port
local Port ←
TCP
connection
← partner Port
IP address Station A IP address Station B
partner Port → → local Port
local Port ←
UDP
connection
← partner Port
ISO-on-TCP supports TSAP lengths (Transport Service Access Point) of
1...16Byte. You may enter the TSAP in ASCII or hexadecimal format. The
calculation of the length happens automatically.
Ports res. port addresses are defining the access point to the user
application within the station/CPU. These must be unambiguous. A port
address should be within the range of 2000...65535. Foreign and local
ports may only be identical with one connection.
