4. In the drop-down list box of the partner end point, select a connection partner. You can
select an unspecified device or a CPU in the project as the communication partner.
Certain connection parameters are then entered automatically.
The following parameters are set:
– Name of the partner end point
– Interface of the partner end point
– IPv4 address of the partner end point
If the connection partners are networked, the name of the subnet is displayed.
5. In the "Configuration type" drop-down list, select between using program blocks or
configured connections.
6. Select an existing connection description DB in the "Connection data" drop-down list or
for configured connections select an existing connection under "Connection name". You
can also create a new connection description DB or a new configured connection. Later,
you can still select other connection description DBs or configured connections or change
the names of the connection description DBs in order to create new data blocks:
– You can also see the selected data block at the interconnection of the CONNECT
input parameter of the selected TCON, TSEND_C or TRCV_C instruction.
– If you have already specified a connection description DB for the connection partner
using the CONNECT parameter of the TCON, TSEND_C or TRCV_C instruction, you
can either use this DB or create a new DB.
– If you edit the name of the displayed data block in the drop-down list, a new data block
with the changed name but with the same structure and content is generated and
used for the connection.
– Changed names of a data block must be unique in the context of the communication
partner.
– A connection description DB must have the structure TCON_Param, TCON_IP_v4 or
TCON_IP_RFC, depending on CPU type and connection.
– A data block cannot be selected for an unspecified partner.
