Simulation
|
Define the conditions that will be used during an EIKON for WebCTRL simulation.
|
RefName
|
Use the default reference name unless you want a more descriptive name for this microblock for graphics, source tree rules, or network links. All reference names in a control program must be unique.
|
Network Visible?
|
When you set Network Visible? to Yes, the microblock's output is visible to third-party equipment.
Any BACnet device on the network can read or change the value of this output as long as the device uses a priority higher than 16 (or, if the lock parameter is set to Y, a priority higher than 8).
|
(Display) Name
|
The microblock label used in the interface. You can use any characters (including spaces) in this field, except for the " character.
|
Description
|
BACnet-visible description of the microblock.
|
Expander
|
Indicates the number of the expander module (normally 0-5 or 0-6). The Technical Instructions document for your hardware device or the Technical Handbook can provide you with guidelines for determining the Expander. These settings can be adjusted on the Properties page; however, these settings should not need to be adjusted after the initial installation unless the input point on the device is changed.
|
Input Type
|
Set the Input Type to match the equipment input type the microblock will read.
Binary
- Universal Input
- H-O-A Status Feedback
- Dry Contact
- Counter Input
Analog
- Universal Input
- Pneumatic 0-64 PSI
- Special
- Thermistor
- 05 Volt
- 020 mA
|
Input Number
|
Set the Input Number to match the equipment input number the microblock will read.
|
Units
|
The Units field has two parts, a scrolling list and a number field. If the unit of measure that you need is not available in the scrolling list, enter a BACnet number in the number field. Units can be read directly from the BACnet object but setting this property in the microblock reduces network traffic.
Units, abbreviations, and BACnet numbers
|
Minimum Value Maximum Value
|
You can use Minimum Value and Maximum Value to set the actuator limits for the equipment.
|
Resolution
|
The smallest recognizable change, in engineering units, for the equipment.
|
COV Increment
|
The COV (Change of Value) Increment is the minimum change in the present value that will cause a microblock to send data to its COV Subscribers.
|
Gain
|
The Gain setting determines the quantity that each pulse represents.
|
Pulse Window
|
The Pulse Window setting determines the time period over which the rate is averaged. The average is calculated every minute using the following formula (where P is the number of pulses received over the duration of the pulse window, M is Pulse window setting, and G is the Gain setting):
P/M x G = microblock value
NOTE The Pulse to Analog Input microblock cannot count more than 4 pulses per second. Because of the delay associated with the T-Line sub-net, the use of this microblock in T-Line modules is not recommended or supported.
|
Pulse Input
|
The TLO can operate in one of three ways: as a Pulse Input, a Fixed Width Input, or a Mechanical Input. When operating as a Pulse Input, the microblock reads the signal from a toggle switch or button. Each time the switch or button is pressed, the override is activated for a preset amount of time, defined by the Each pulse setting, up to a specified maximum which is defined by the Max accum setting. On the Properties page, these settings can be adjusted using the For each pulse, add ____ (mm:ss), up to a maximum of _____ (mm:ss) properties. In the Pulse Input section you can also define a reset signal using the option Cancel override if input closed for > __ sec; this is the amount of time you must hold the override switch to cancel the override. On the Properties page, this setting can be adjusted using the Hold Input for ___ (sec) to reset property.
|
Fixed Width Input
|
The Fixed Width Input section is used in the same way as Pulse Input, except that the preset time cannot be extended and you cannot define a reset signal. Use the Each pulse setting to define the override time. On the Properties page, you can define the override time using the Broadcast Request time property.
|
Mechanical Timer Mode
|
In Mechanical Timer mode, the override is enabled by a device that produces a constant signal such as a wind-up timer. Use the Input closed setting in the Mechanical Input section to define the amount of time the override will be in effect. On the Properties page, you can change this setting using the Broadcast Request Time property.
NOTE The Time Local Override microblock has a maximum accumulated time of 546 minutes.
|
Editing Privilege
|
Preset (the default Editing Privilege) indicates that each property in a microblock has an appropriate privilege assigned to it.
If you change the Editing Privilege, all the properties in that microblock are assigned to that one editing privilege, which is not always desirable.
