Local/Partner connection
A Local / Partner (remote) connection defines a logical assignment of two communication
partners to establish communication services. A connection defines the following:
● Communication partners involved (One active, one passive)
● Type of connection (for example, a PLC, HMI, or device connection)
● Connection path
Communication partners execute the instructions to set up and establish the communication
connection. You use parameters to specify the active and passive communication end point
partners. After the connection is set up and established, it is automatically maintained and
monitored by the CPU. Refer to the section on "Configuring the Local/Partner connection"
(Page 150) for information about configuring the parameters for the connection.
If the connection is terminated (for example, due to a line break), the active partner attempts
to re-establish the configured connection. You do not have to execute the communication
instruction again.
The CPU can communicate with other CPUs, with programming devices, with HMI devices,
and with non-Siemens devices using standard TCP communications protocols.
