Technical Data

FeatureDescription
Maximum number of total cyclic input data1440 bytes
Maximum number of total cyclic output data1440 bytes
Maximum number of submodules32 submodules in total
Multiple Application Relations (AR)The Stack can handle up to 4 IO-ARs and one Supervisor-DA AR at the same time.
Acyclic communication

Read/Write Record, max. 1024 Bytes/Telegram for standard firmware.

Alarm TypesProcess Alarm, Diagnostic Alarm, Return of Submodule Alarm (implicit), Plug Alarm (implicit), Pull Alarm (implicit)
Diagnosis Entries

The stack supports up to 256 application diagnosis records of type Channel or Extended Channel Diagnosis

Identification & Maintenance

I&M0-4 Read/Write: Either built in for Slot 0/Subslot 1 or pass through to application for any submodule.

Topology recognitionLLDP, SNMP V1, MIB2, physical device

Minimum cycle time

1 ms for RT

250µs for IRT

Note: The network cycle time of 250 µs can be used with asynchroneous applications only, which do not update the dual-port memory on every network cycle.

(Isochroneous) applications are not supported for 250 µs network cycle time, only for 500 µs, 1 ms, 2 ms and 4 ms.

IRT Supportsupported (RT_CLASS_3)

Media Redundancy

MRP client is supported
Additional supported featuresDCP, VLAN- and priority tagging, Shared Device
Baud rate100 MBit/s

Data transport layer

Ethernet II, IEEE 802.3
Profinet IO specification

V2.3 (advanced startup) is implemented

V2.2 (legacy startup) is supported

Maximum supported GSDML Parameter PNIO_Version: 2.42 (when using newest available stack/firmware version)

Configuration

Configuration is done by sending packets to the stack or by using SYCON.net configuration database.

Diagnostic

Some elementary diagnosis information can be read using the service “Get Diagnosis Service”. This service might be extended in future.
