7.11 Function blocks for Ethernet communication
7.11.1 IP communication blocks
The IP communication blocks enable IEC 61131-5-compliant communication between con-
trollers via Ethernet or communication between controllers and Ethernet devices via TCP/IP
or UDP/IP.
The functional blocks are valid for the controllers listed in the table below in the specified
hardware/firmware versions and support the specified maximum number of TCP/IP or
UDP/IP communication connections:

Table 7-2 Overview of the IP communication blocks
Function block Short description
IP_CONNECT Establishes a connection between two communication partners.
IP_USEND Transmits data to a communication partner.
IP_URCV Receives data from a communication partner.
The IP communication blocks are described in the PC Worx (Express) online help.
The extensions for the TCP/IP and UDP/IP function blocks are described in the "AH EN
FB TCP/UDP COMMUNICATION" application note.
