### BACnet Multi-State Value Parameter - 20 States IMPORTANT This microblock has been retired from the EIKON® microblock menu as of v5.5 and the release of ZS Sensors. However, it is still supported in the EIKON® application, controllers, and the WebCTRL® application. For new applications, use the BACnet Multi-State Value Parameter microblock.
Microblock family | Sys In microblocks

What it does | 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 assign a display name to each parameter on the microblock. This display name is used as the name of the BACnet object.
Click for details below Properties Alarms
#### 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 (in a WebCTRL® or Field Assistant system only) | Check to output the locked value from the microblock instead of the microblock's calculated value.
Editing Privilege (EIKON® application only) | 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.
State Text | Enter the text that will appear on the Properties page when the device is in each state. Type one line of text for each state, putting them in the order of the numerical values that represent the states. For example, the first line of text is for value 1, the second line of text is for value 2, etc. You can enter states for values 1 to 20, with each state no more than 20 characters. NOTE To have a state trigger an alarm, type`;alarm` at the end of that state's text.
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.
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.
