Updating Interface after Initial Install

After the initial installation of Progman with CIP 15.0, the firmware installed on the interfaces that will be used with Progman must first be updated. If the firmware level of the interface is not at a predefined level then it will not be recognized/identified within the Progman application, thereby not allowing a connection to the interface. This update only needs to be performed when an interface is used for the first time with Progman.

Using the GT1 update the firmware in the interface.

Select the interface

With a connection to the interface established a message should be displayed indicating that the firmware in the head needs to be updated, perform the update by selecting the "Diagnostic head Update" button.

After the update is complete select "Quit connecting".

Access Progman and verify that the interface is recognized

From Progman the firmware level of the interface should also be checked and updated if necessary. Progman does not automatically inform the user if the firmware of the interface needs to be updated.

Updates to the interface are checked and performed by selecting the specific interface from the list, located under "Administration" - "Interfaces", then selecting "Interface Update" (refer to previous page for additional information).
