### BACnet Multi-State Value Parameter The information below provides a FULL description of this microblock and all of its properties. What information you see and what you can do with it depends on your license and the application you are in, and in some cases, a controller's driver version.
Microblock family | Sys In microblocks
Icon and symbol |
What it does | This microblock specifies a signal to be sent to the output wire. Multi-State microblocks are used to indicate values that have more than two discrete states (20 maximum). For example, a parameter may have states of High, Medium, and Low rather than a numeric value. Any BACnet device on the network can read or change the value of this parameter. If no BACnet device changes the value of this parameter, the default value is used. The value appears to other BACnet devices as the Present Value property of this BACnet object. You can configure this microblock to make its value available on the Rnet.
Click for details below Properties Alarms Rnet
#### Properties TIPS Alt+click any value in the WebCTRL® or Field Assistant interface to view property details, including its editing privilege and expression (location path) for use on graphics. You can right-click some properties in the EIKON® Property Editor and select Make editable or Make read-only to determine that property's functionality in your system.
Display Name | The microblock label used in the EIKON® application and the WebCTRL® interface. You can use any characters except the " character.
Reference Name RefName | Use the default reference name unless you want a more descriptive name for graphics or network links. Limitations: lower case only limited to 40 characters cannot begin with a number must be unique within a control program
Description | (optional) A BACnet-visible microblock description.
Lock Present Value | Check to output the locked value from the microblock instead of the microblock's calculated value.
Editing Privilege | Preset - Each microblock property has an appropriate privilege or role assigned to it. You can use Global Modify in the WebCTRL® interface to find out what the actual privilege is. CAUTION If you change the Editing Privilege from Preset, the privilege you select will be used for all properties of this microblock, which is not always desirable.
Default Value | The value the control program uses until a user changes the value in the system interface.
Momentary | NOTE A control program with this feature enabled works only with v5.5 or later systems and v5.5 or later drivers. This feature cannot be used in a control program for a Room Controller, S6104, UNI, or M line controller. Lets the WebCTRL® user change the parameter to the new state for one execution of logic. The WebCTRL® application then changes the parameter back to the original state.
State Text | You must define the text that will appear on the Properties page when the device is in each state. For Value 1, type the text in the field under BACnet Text. For each additional state, click Add and then type the text. To have a state put the BACnet object in an alarm or fault condition, select the appropriate option for that state under Alarm/Fault. You can set a maximum of 10 states to fault, and a maximum of 10 states to alarm. If you checked Enable Rnet for ZS Sensors on the Rnet tab, type the text that you want to appear on a ZS Sensor display in the field under Rnet Text. The Preview field shows you how it will look on the sensor. NOTE The letters K, M, Q, V, W, X do not display on the screen.
Property Page Text
Show Property Page Text | Check to show this microblock's value on the equipment's Properties page.
Property Page Text | You can edit the microblock description that appears on the Properties page. See "Editing Properties page text using special characters" and "Formatting a microblock property" in EIKON® Help.
BACnet Configuration
Network Visible | Check to allow other BACnet equipment to read or change the microblock's present value. Must be checked for this microblock to generate alarms.
Critical Value | If your control program has logic that writes a critical value to this microblock periodically, select this option to have the system attempt to upload this microblock’s value (Relinquish Default property) and preserve it through a download, controller restart, or power loss.
Object Instance | Auto-assign - A BACnet Object ID is assigned by the system. Use specific value - (0–3999999) Assign a number that is unique within the controller.
#### Alarms
Potential alarm source | Check to make this microblock available in the system's Alarm Sources list.
Critical | Determines the color of the system-wide alarm button when the alarm comes in if the alarm's Template field is set to Universal. = Critical = Non-critical
Category | The category you want to use to filter this microblock's alarms on the system's Alarms page > View tab.
Template | Universal - Allows your system to use the Alarm text and Return text defined in the microblock, and the Critical checkbox to determine the color of the system-wide alarm button when the alarm comes in.
Alarm
Alarm Enabled | Check to send a message when this microblock indicates an alarm condition.
Delay Seconds | The time the microblock's present value must remain in an alarm condition before the microblock sends an alarm.
Alarm text | The message displayed on the WebCTRL® Alarms page > View tab when an alarm condition occurs. A relative path is useful for alarm messages that you will reuse in multiple WebCTRL® locations because the path is relative to the item that contains the path.
Alarm requires acknowledge | Check to require that an operator acknowledge alarm notifications on the system's Alarms page > View tab.
Return to Normal
Return Enabled | Check to send a message when an alarm condition has returned to normal.
Return text | The message displayed on the WebCTRL® Alarms page > View tab when an alarm condition returns to normal. A relative path is useful for alarm messages that you will reuse in multiple WebCTRL® locations because the path is relative to the item that contains the path.
Return requires acknowledge | Check to require that an operator acknowledge return-to-normal notifications on the system's Alarms page > View tab.
Fault
Fault Enabled | Check to send a message when a fault condition occurs, such as a misconfigured or non-existent sensor.
#### Rnet NOTE A control program that uses these Rnet features works only with v5.5 or later systems and v5.5 or later drivers.
Enable Rnet | Check to allow this microblock to communicate its value(s) to and from a sensor.
Rnet Tag | All values from a ZS or wireless sensor must have an Rnet tag that defines what type of information this microblock's value represents. For a ZS sensor, it also determines how the sensor will display the value. For example, if you select Fan Speed Request (600), the sensor displays the state text and the number 600 in the lower left corner to identify the value is a fan speed request. NOTES If you select Fan Speed Request or Zone Mode Request, the Critical Value field on the Properties tab is automatically enabled to prevent a parameter mismatch in the WebCTRL® application if a user changes the values on the sensor. If the Rnet tag droplist does not have the tag you want, you can create a custom tag in the EIKON® application.
Editable | Check under Occupied or Unoccupied to make each setpoint editable on a ZS Sensor.
ZS Sensor Display Configuration |
Show on: | Check the sensor screen(s) that you want this microblock's values displayed on. Home Screen (1): When more than one value is assigned to the Home screen, the values cycle from one to the next. Typically, the first item displays for 10 seconds and any other items display for 3 seconds each. Information Screen (2): This screen is accessed by pressing the sensor's button. Diagnostics Screen (3): This screen is accessed by holding the sensor's button for at least 3 seconds. NOTE Select Reorder > Sensor Display Order to define the order in which multiple microblock values will appear on each sensor screen.
