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:
•
•
Redundant Media
I/O-Devices in the
Ring
VersaMax PNS
and/or RX3i CEP
An RX3i PNS (or
RX3i GCG) using
Port 1 & Port 2 for
ring
An RX3i PNS using
Port 3 or Port 4 for
the ring
An RSTi-EP PNS
VersaMax PNS
and/or RX3i CEP
An RX3i PNS (or
RX3i GCG) using
Port 1 & Port 2 for
ring
An RX3i PNS,
VersaMax PNS
and/or RX3i CEP, or
RX3i GCG
An RSTi-EP PNS
An RX3i PNS,
VersaMax PNS
and/or RX3i CEP, or
RX3i GCG
An RSTi-EP PNS
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.
