APPENDIX 2 : PROFINET IO RT INTERFACE
PROFINET is the standard for industrial ethernet based on IEEE 802.xx. PROFINET is based on the
100 Mb/s-version of full-duplex and switched Ethernet. PROFINET IO is designed for the fast data
exchange between Ethernet-based controllers (master functionality) and field devices (slave
functionality) with cycle times up to 10 ms.
CAUTION!
The module internal gateway must not be overloaded. If the communication
load becomes too high, this gateway circuit might fail. The result is a temporary but
complete failure of the control functionality until the module is powered off. In order to
avoid overcharge, do not send new data faster than every
10 ms
. This can be assured by calling the
driver function in an appropriate cycle of the PLC.
ProfiNet Installation guideline
The ProfiNet IO field devices are connected exclusively via switches as network components. A
ProfiNet IO network can be set up in star, tree, line or ring topology. ProfiNet IO is based on the
Fast Ethernet standard transmission with 100 Mbit / s. The transmission media are copper cables
CAT5.
For the IP20 environment in the control cabinet, the RJ45 connector CAT5 according to EN 50173
or ISO / IEC 11801 is used. The pin assignment is compatible with the Ethernet standard (ISO / IEC
8802-3).
The connection between ProfiNet participants is called ProfiNet channel. In most cases, ProfiNet
channels are built with copper cables to IEC 61784-5-3 and IEC 24702. The maximum length of a
ProfiNet channel, which is constructed with copper cables is 100 m.
PROFINET address assignment
All PROFINET IO slave devices need name and IP address to initiate communication.
Both are assigned to the device by the ProfiNet-IO-controller (PLC). The device name of the
PROFINET IO device is stored in persistent memory in the device. It can be modified by a Profinet
IO supervisor, e.g. the programming system of the belonging PLC.
