Description: This parameter specifies what action the MCA board will
take when a PLC Controller RIO communication fault occurs. Bit 0
indicates whether a Reset\Program\Test indication from the PLC causes a
soft (bit 0=1) or warning (bit 0=0) fault to occur. Bit 3 indicates whether a
loss of communication causes a soft (bit 3=1) or warning (bit 3=0) fault to
occur. Bit 1 determines whether the Drive maintains last state data (bit
1=1) or the data is zeroed out (bit 1=0). If bit 0 or bit 3 are set for
“Warning” and the PLC Controller faults, the Drive will continue
operation. If bit 1 is cleared or “zeroed”, the PLC Controller fault is
cleared, the Drive fault is also cleared, and transition on Image will occur.
ATTENTION: The bit 0 and bit 3 should normally never be set for
“Warning” during regular operation. If the Drive is allowed to continue
operation after a Fault, unintended operation of the controlled equipment
could occur resulting in machine or process damage and possible injury to
personnel.

Parameter 588 – [A>Redund Chan No]
Parameter 538 – [B>Redund Chan No]
Use: Specifies RIO Redundant Channel Number
Parameter Type: Setup
Program Terminal Units: None
Minimum Value: 0
Maximum Value: 1
Default Value: 0
Description: This parameter determines which channel number will be
used by the Drive for control purposes. Data and messages from the
selected channel will be passed to the Drive. Data and messages from the
other channel will be discarded. The choices are:
0 = Channel A
1 = Channel B
This parameter is only active when both channels are setup for RIO and
the redundant mode is selected on the DIP switches. Image from the
Drive will go to both PLC’s regardless of parameter setting.
