IGS - Industrial Gateway Server Discovery Agent
The IGS - Industrial Gateway Server Discovery Agent examines an exported address and tag description file with an .L5K file extension and finds all the tags defined for a device. An .L5K file is exported from the Rockwell RSLogix 5000 programming software, containing address and tag information in an RSLogix project for a ControlLogix PLC.
You select the IGS - Industrial Gateway Server Discovery Agent on the Select a Discovery Agent page of the Discovery Agent Selection Wizard.
This section tells you how to use the Discovery Agent Selection Wizard to choose the IGS - Industrial Gateway Server Discovery Agent and how to extract symbol information from a Rockwell RSLogix .L5K file for ControlLogix PLCs. When you click the Finish button at the end of the wizard the symbol information is extracted from the selected file, is read by the Discover and Auto Configure, and then displayed in the spreadsheet.
The following table describes the columns exclusive to the IGS - Industrial Gateway Server Discovery Agent that are displayed in the spreadsheet.

IMPORTANT:
- This Discovery Agent supports only the file or memory types supported by the GE IGS driver version 7.41 and 7.51 or greater.
- The Discovery Agent does not perform any Address Range checking. You need to make sure that the imported addresses match those in the PLC.
- The Discovery Agent imports all the file or memory types that are supported by the IGS driver. The PLC may only support a sub-set of the memory types. Therefore, when configuring your driver, you need to map it to the device with the appropriate PLC type. Otherwise, you may get errors when trying to add tags to iFIX or the driver configurations.
- The IGS driver configuration tags displayed in the tree view and spreadsheet are not limited to ControlLogix PLCs. You can browse all the configured channels and devices in your IGS Server.
- When you are using the IGS Discovery Agent, the individual tag information does not automatically display in the system tree; only the top level initially displays. As you expand each level, the IGS Discovery Agent gets and displays the data for that level. For this reason, the IGS Item Status column may not display the status you expect.
- Because the IGS Server is browsed only when requested (that is, when a branch is expanded), when you rerun the IGS Discovery Agent, the IGS Item Status field updates only those items already displayed in the spreadsheet. When you browse for items for the very first time, the status field will always display New, regardless of whether there were changes to the IGS Server since the first time it was browsed. Only those items already displayed in the spreadsheet show an updated status.
