You can configure LAN redundancy simply by enabling it in the SCU. You must have a protocol enabled so that the SCU is configured for network support.
To enable LAN redundancy, click the Advanced button on the Network Configuration dialog box. A caution message box warns you not to modify these values without familiarity with the system. If you are unsure as to how to proceed, refer to the Advanced Topics chapter and your network documentation. To continue, click Yes.
Refer to the Mastering iFIX manual for more information on configuring LAN redundancy in iFIX.
