 Operation Procedure
In case that FOUNDATION fieldbus H1 communication suddenly stops, which functioned
properly on FieldMate before, execute the following operation procedure.
1. Exit FieldMate.
2. Activate /FM/Tool/FMNIFBUSClear.exe
3. A window above is displayed. Check “Number of Configured VCRs”. If the values are close
to 100, VCR needs to be cleared. Proceed 3. If the valued are small, the other cause of
trouble such as communication card disorder is expected.
4. Select “Clear Stored VCRs” and exit.
5. Restart FieldMate and check whether FOUNDATION fieldbus H1 communication functions
properly.
