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.
