If any third-party items participate in the ring, the minimum I/O Update Rate is the larger of the
following two options, regardless of which ports are used for the ring:
• The smallest I/O Update Rate selectable within PAC MACHINE EDITION that is more than 1/2
of the largest worst-case ring recovery time among the third-party items. For example, if
the manufacturer states that the worst-case ring recovery time is 96ms, the rate needs to
be more than 96ms divided by 2, which is 48ms. The next available rate above 48ms is
64ms.
•
16ms I/O Update Rate. When using an I/O Update Rate of 16ms, set the Default Test
Interval to 10ms and the Test Monitoring Count to 2 on the Media Redundancy Manager.
