Description
5760 bytes (including IOxS status bytes)
1440 bytes per device (=IOCR data length including
IOxS status bytes)
1440 bytes per device (=IOCR data length including
IOxS status bytes)
One 200-byte buffer per IO device
Name assignment of IO devices (DCP SET

NameOfStation)
Set IP address of IO device (DCP SET IP)

Set signal of IO device (DCP SET SIGNAL)

Reset IO device to factory settings (DCP Reset

FactorySettings)
 Bus scan (DCP IDENTIFY ALL)
RTC – Real Time Cyclic Protocol, Class 1

RTA – Real Time Acyclic Protocol

DCP – Discovery and Configuration Protocol

CL-RPC – Connectionless Remote Procedure Call

Supported
1ms
Different IO devices can be configured with different
cycle times
Fast startup of PROFINET IO devices supported
100Mbit/s
Full-duplex mode
Ethernet II, IEEE 802.3
Maximum 1MB
RT over UDP not supported

Multicast communication not supported

DHCP is not supported (neither for IO controller

nor for IO devices)
Only one IOCR per IO device

NameOfStation of IO controller CANNOT be set

using the DCP SET NameOfStation service but only
at start-up while configuring the IO controller
The buffer for IO device diagnosis data will be

overwritten in case of multiple diagnostic events.
Only one (the last) event is stored at the same
time. If a single event produces more than 200
bytes of diagnosis data, only the first 200 bytes
will be taken care of.
The usable (minimum) cycle time depends on the

number of used IO devices, the number of used
input and output data. The cycle time, the number
of configured IO devices and the amount of IO da-
ta depend on each other. For example it is not
possible due to performance reasons to have 128
IO devices communicate with a cycle time of 1ms.
The size of the bus configuration file is limited by

the size of the RAM disk (1MB)
Write multiple record service is not supported

