    Hi  ,

    Apart from your alarms not working, do you have normal communication for your real-time values (no #COM or #BAD visible on screen)?

    If real-time data is not working as well, please inform us what configuration steps you took to convert from MODNET to OFSOPC, like:
    - I/O device: Driver should be OFSOPC; Address should be the same name as the name of the PLC defined in the OFS Configuration Tool.
    - Variables: For legacy modbus/TCP communication (like MODNET) without performance benefits, you can keep the MODBUS addresses unaltered.
                       For performance optimized communication, you have to change the addresses to name-based standard OPC tag syntax (conform the variable names used in your PLC application). You have to enable data-dictionary in your PLC-application and in the OFS configuration tool as well. Please consult the appropriate manuals for details.

    If only the alarms are not working, you might consider deleting your alarm database.
    To do this, please remove the complete alarm database folder which can be found as a subdirectory in the PlantSCADA data folder.

    In either case, please consult the PlantSCADA syslog***.dat files for more information on your issue. These can be found in the PlantSCADA log folder.
