The setpoints can be controlled by using the two control options explained below. All
setpoints have these controlling options.
The two main setpoint control options are.
Invert
– This option toggles the Setpoint control logic between the default normal and
inverted state. The function does not change, only the operation is inverted, e.g. if
setpoint is on in its normal state, inverting the signal will mean the setpoint will be off in
the normal state. Default state is not inverted (not ticked)
Window – This option toggles the Set point operation between the Default (Deadband)
and Windowed modes.

Default (Windowed not ticked) - If the Analog Input is greater than the Upper Set
point, the set-point status will be active
(on, “1”). When the Analog Input is less
than the Lower Set Point
the setpoint will reset (off, “0”). Note: The Upper Set
Point must always be higher than the Lower Set Point.”

Windowed
– If the analog value is inside the upper and lower setpoints, the
se
tpoint will be active (on, “1”), and if the analog value is outside of these
setpoints the setpoint will be reset (off, “0”)
Analog Outputs
Name
– The inputs can be named to help
with configuration or use the default, up to 30
characters including spaces.
Failsafe Time (sec) – The Fail Safe Time is
the time the output needs to count down
before activating the failsafe state.
Receiving an update or a COS message
will
reset the Fail Safe Timer back to its
starting value. If the Fail Safe Timer gets down to zero then the output will be set to the
Fail Safe state (mA)
It is recommend this Fail Safe Time be configured for a little more than twice the update
time of the input that is mapped to it, that way the output will reset if it fails to receive
two update messages. Entering a zero in the Fail Safe Time will disable.
Failsafe value (mA) – The value that you wish the output to be set to on completion of
the failsafe timeout.
4.3.10 Serial Expansion I/O
Adding modules
Additional WI-I/O-EX-1-S serial expansion I/O modules can be added if more I/O is
required.
When connecting expansion I/O module to the WI-I/O 9-U2 the RS485 serial port is
configured to communicate Modbus protocol by default.
