When a communication idle state occurs the relays can execute two
types of behavior. Only valid for output relays used as general purpose
field outputs. The behavior is selected on a per bit basis. See the Comm
Idle Behavior parameter to set the behavior of outputs used in the control
profile. Each available output is assigned a bit in the Comm Idle Output
Action word. If the bit is “0” then the state of the output is determined by
the (Comm Idle Output State) Parameter. If the bit is “1” it will hold last
state.

This parameters works with the Comm Idle Output Action parameter. Only
if that parameter is set to “Use Idle State” does this parameter apply. This
parameter then selects the state of the outputs, On or Off when a
communication Idle occurs. The behavior is selected on a per bit basis.
Only valid for output relays used as general purpose field outputs.

Select the behavior of the Latching Relay (Output 3) when power is
removed from the C445, provided the Base Control Module was ordered
with the latching relay option. Default: Turn Off, emulating a non-latching
relay.

Three-phase configuration is the default and is used for 3-phase motors.
The C445 also supports single phase motors by changing this setting to
Single Phase.
