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 which might need to be taken into account when migrating.

  • Hardware related
    • 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 related
    • The increased performance and therefore accelerated script execution may have an effect on the application protocol timing.
    • The PROFINET signaling event now triggers a script event. It is no longer reflected in the ReadBusState parameter.

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.
