UNIGATE IC2-PROFINET

UNIGATE IC2 PROFINET 2Port is pin compatible with respect to UNIGATE IC-PROFINET 2Port.

Migration from UNIGATE IC to UNIGATE IC2

For the most part the UNIGATE IC2 PROFINET 2Port is compatible with UNIGATE IC-PROFINET 2Port. There are however subtle differences with respect to the device behaviour and the extended functionality which might need to be taken into account when migrating.

Hardware

• For the PROFINET signaling (device identification) feature the Link LED is now used, as opposed to the Error LED.
• The IC2's Link LED indicates the link status and the PROFINET signal event. It does not indicate Ethernet activity.

Script

• The increased performance and therefore accelerated script execution may have an effect on the application protocol timing.
• The parameter Bus_Type returns the value 0x91 (UNIGATE IC-PN: 0xBD).
• The PROFINET signalling event now triggers a script event. It is no longer reflected in the ReadBusState parameter. Event activation: set(Event_Typ, 0xA);

Device description file (GSD file)

• It is necessary creating a new GSD file which fits the UNIGATE IC2 PROFINET's (extended) capabilities and properties. It is recommended using the UNIGATE IC2 PROFINET's GSD template as a starting point. Please find the template on the devices' internal webpage.
• Within the module definitions it is no longer necessary to reflect the module's I/O size in the module-ID (e. g. ID 0x00030005 for a module with 3 bytes input and 5 bytes output data). The I/O size is solely determined by the data-item entries in the module definition.

PROFINET Certificate

PROFINET certificates of devices, which are based on UNIGATE IC PROFINET, are not transferable.

Web and FTP servers

The UNIGATE IC2 PROFINET uses new web and FTP servers, resulting in various changes and innovations. The servers are no longer permanently active, but can be activated as required. Access protection has also been improved. For further details, please refer to the manual.

Comparison IC(1) to IC2

UNIGATE IC(1) - PROFINET can be replaced by UNIGATE IC2 - PROFINET. An overview of the differences can be found in the Comparison table on page Comparison UNIGATE IC(1) - PROFINET to UNIGATE IC2 - PROFINET.

Redundancy (MRP)

The MRP functionality is completely encapsulated in the UNIGATE. There is no action required by the device script or the application in order to use MRP. In the GSD file the entries "MediaRedundancy" and "SystemRedundancy" are relevant.
