Enter the RPI time that will provide optimum backplane performance for your
application, within the range from 5
MS
to 750
MS
.
RPI Time 750 milliseconds
If ALL of the following conditions are true:

MVI56-PDPMV1 module firmware version 1.21 (or later)

MVI56-PDPMV1 module configured in FLEX mode ( U
SE
L
EGACY
M
ODE
= N
O
)

MVI56-PDPMV1 module is located in either the local rack or remote rack
through EtherNet/IP adapters
For optimal performance set the RPI time as 750
MS
. For this scenario, the
module will use the IOT (Immediate Output) instruction that will override the
configured RPI time. Setting a lower RPI time will cause unnecessary interrupts
to the module, delaying data updates and lowering data throughput.
