Technical Data

Feature

Description

Maximum number of total cyclic input data

1440 bytes

Maximum number of total cyclic output data

1440 bytes

Maximum number of submodules

255 submodules per Application Relation at the same time, 1000 submodules can be configured

Multiple Application Relations (AR)

The Stack can handle up to 8 IO-ARs, one Supervisor AR and one Supervisor-DA AR at the same time.

The amount of ARs to be acceptec can be configured via taglist (NXLFW) respectively startup parameters (NXLOM).

Acyclic communication

Read/Write Record, max. 8 KB for standard firmware using fragmentation.

LOM Target supports up to 32 KB per Telegram.

Alarm Types

Process Alarm, Diagnostic Alarm, Return of Submodule Alarm, Plug Alarm (implicit), Pull Alarm (implicit)

Identification & Maintenance

Reading and writing of I&M1-4.F (if the stack is configured to handle I&M by itself (this is the default) the GSDML device description shall be adapted to indicate the support of I&M1-4)

Topology recognition

LLDP, SNMP V1, MIB2, physical device

Minimum cycle time

1 ms for RT (all chip types)

1ms for IRT (netX50)

250µs for IRT (netX51, netX100, netX500)

IRT Support

supported (RT_CLASS_3)

Media Redundancy

MRP client is supported

Additional supported features

DCP, VLAN- and priority tagging, Shared Device

Baud rate

100 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: 2.41 (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.

Cyclic input/output data

The stack has the ability to convert the byte order of cyclic process data image.
