427 Redundant Channel Number
[Redund Chan No]
(When Redundant RIO Is Used)
Redund Chan No determines which channel number
the 1336 FORCE will use for control purposes.
Input image data and messages from the selected
channel are passed to the drive, while input image
data from the other channel are discarded.
Messages from the other channel are still accepted
if the other channel is configured for RIO adapter
mode with block transfer. Output image data is sent
to both channels.
The choices are 0 for channel A and 1 for channel
B. This is only active when both channels are set up
for RIO and the redundant mode is selected on the
DIP switches. Images from the 1336 FORCE will go
to both PLCs regardless of the parameter setting.
Channel A RIO Scanner Retries
[ChA RIOS Retries]
(When RIO Scanner Is Used)
ChA RIOS Retries counts the number of
communication retries for all entries in the scan list.
This is only active when RIO scanner mode is
selected on the DIP switches.
