Input Pin Name
Pin Type
Description
Key:
PD
= Physical Digital,
PA
= Physical Analog,
PP
= Physical Pulse
VD
= Virtual Digital,
VN
= Virtual Numeric
VD
= Virtual Digital,
VN
= Virtual Numeric
Input Name
All
Assigns a name to the Input pin that will be used in display, logging, and alarms
Display
All
Assigns the pin to a specific panel within the control panel display. Set to Off for pins that
will not be displayed on control panel.
Note
– Output pins assigned to the control panel can be set to a value by a user. To
create a read-only display assign the input pin to a virtual input pin and display the input
pin.
Cloud Display
All
Defines which of 8 possible attributes this pins value will appear on a SkyCloud pin
Log
All
Specifies in seconds the frequency at which the pins value will be logged. If set to zero (0)
logging on this pin is turned off.
Note
– See Logging Rules for more information on logging
Initial Value
VD, VN
Specifies how the pin will be initialized upon power up or restart. Choices for digital are
On, Off, or Last. The Last setting will provide a persistent pin value. Numeric pins are set
to the value as specified.
Unit of Measure
PA, PP, VN
This field defines the units of measure to be used with the input, PSI or degrees for
instance. The control panel display will use this value in combination with the sensor
reading to create a display such as 27.3 PSI.
Threshold 1 – n
PA, PP, VN
Pull down field to define threshold type, Less Than or Greater Than and Edge Sensitive or
Level Sensitive.
Trigger Value
PA, PP, VN
The measured value at which the threshold will occur
Reset Value
PA, PP, VN
Sometimes referred to as the hysteresis band. The value associated with a trigger value
at which the threshold will be reset so that it can be triggered again. Example: If a level
sensor triggers at greater than 17 feet it might be assigned a reset value of less than 15
feet. Once the level was sensed at 17 feet the tank level would have to return to 15 feet
before another 17 foot event could be triggered. The zone between trigger and reset
eliminates multiple alarms if the value is oscillating at approximately the trigger point.
