Configuring Hardware and Communication Connections STEP 7.pdf

TCP Connection
Configuring Connections
The TCP connection has the following features:
• Complies with the TCP/IP standard (Transmission Control Protocol/Internet
Protocol)
• Enables communication to a partner (such as a PC or non-Siemens device) that
supports sending or receiving data according to TCP/IP.
• You can transmit data by means of the utilities Send/Receive or Fetch and
Write.
• For Industrial Ethernet only
• As a rule, you can use the TCP/IP implementation in the operating system of
the PC.
UDP Connection
The UDP (User Datagram Protocol) connection has the following features:
• For Industrial Ethernet (TCP/IP protocol)
• Allows unsecured transfer of contiguous blocks of data between two nodes
E-Mail Connection
The e-mail connection has the following features:
• For Industrial Ethernet (TCP/IP protocol)
• Enables process data, for example, to be sent from data blocks via e-mail using
an IT communications processor
• Using the e-mail connection, you define the mail server via which all e-mails
sent by an IT communications processor are delivered
