Function blocks for Ethernet communication

The function blocks are used to establish Ethernet communication between two communi-
cation partners.
The IP communication blocks listed below enable IEC 61131-5-compliant communication
between controllers via Ethernet or communication between controllers and Ethernet de-
vices via TCP/IP or UDP/IP.
Implement all time and connection monitoring in the application program.
The function blocks are valid for the Inline controllers listed in the table below in the specified
hardware/firmware versions and enable the specified maximum number of TCP/IP or
UDP/IP communication connections:
