8686_en_01 PHOENIX CONTACT 85
4.14 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.
Implement all time and connection monitoring in the application program.
The function blocks are valid for the controllers listed in the table below in the specified hard-
ware/firmware versions and support the specified maximum number of TCP/IP or UDP com-
munication connections:
