Cabling
The JUMO field device with PROFINET IO interface is a single-port PROFINET device. It can be con-
nected to the end of a line or in a star design to an IO controller, an IO supervisor (programming device
and/or PC for project planning), or other Ethernet components such as switches and routers.
(1) PROFINET IO controller (PLC, control station PC, or similar)
(2) JUMO PROFINET IO devices (LAN1 is configurable as an IO device in CODESYS®)
NOTE!
The cyclical data exchange with JUMO PROFINET IO devices is based on the RT protocol (Confor-
mance Class A). PROFINET RT communication cannot be routed. It is thus necessary that the PROF-
INET IO controller and the IO devices be in a common broadcast domain (not connected via a router).
Ethernet standard services (web server, access via JUMO setup program and email function) and NRT
communication (e.g. project planning on the IO supervisor, system boot, noncyclical data) also function
via routers as before.
