### Carrier Analog Point 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 | Carrier microblocks
Icon and symbol |
What it does | The Carrier Analog Point microblock: Can monitor and force (constrain or restrict) a variable in a Carrier device Is visible to the BACnet network Contains a BACnet analog value object Contains a BACnet trend log object Can be an alarm source Can be trended Uses the out-of-service BACnet requirements Can be used in a graphic to force a variable This microblock's poll rate is set in the related Carrier Device microblock. The Carrier Analog Point microblock reads the analog (continuous) value of a physical input on the controller. Then converts the raw data from the sensor to the appropriate range for its unit of measurement (like mA, degrees Fahrenheit, or psi). You can configure this microblock to make its value available on the Rnet of a UPC Open controller.

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.
Name | The microblock label used in the interface. You can use any characters (including spaces) in this field, except for 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.
Com Enabled | Check to enable network communications for this microblock. Uncheck when troubleshooting.
Writable | Check to allow BACnet commands to write to present value.
Force Level | The force level being written to (1-15).
Display resolution | The microblock's value is truncated and incrementally updated as follows: The Display resolution format is used to truncate the microblock’s actual value. For example, if you enter a value from: 0.1 to 0.9, the system displays 1 digit to the right of the decimal 0.01 to 0.99, the system displays 2 digits to the right of the decimal 1 or greater, the system displays a whole number The Display resolution value determines the increment by which the displayed value is updated. For example, if you enter: .2, the system displays 8.4, 8.6, 8.8, ... .03, the system displays 5.09, 5.12, 5.15, ... 10, the system displays 30, 40, 50, ...
Path | Use the information below to format a valid path for the microblock you are using to read or write to the CCN point. Each item in the path is limited to 8 alpha-numeric characters. Check Editable if you want the path to be editable in the WebCTRL® interface. Path format: CCN://LINK/<table name>/<point name><:instance#><@force level> LINK represents the CCN device defined in the CCN Controller microblock. <table name> - Use one of the following: Definition table name:Data table name Example: `CCN://LINK/MYTABLE:MYDATA1` Definition table name:Instance number Example: `CCN://LINK/MYTABLE:1` Data table name Example: `CCN://LINK/MYDATA1` Where: Definition table name is the name of the POC table that describes the data structure of the child tables. Data table name is the name of the table instance that contains the variable or field being referenced. Instance# is the table instance number <point name> Example: `CCN://LINK/.../HEATSP` `` <:instance#> (Optional) - Use the instance number of the point name if the table has more than one point with the same name. <@force level> (Optional) - The force level being written to (a value 1–15) Example: `CCN://LINK/HOLIDAYS:HOLIDAY1/HEATSP@4` You can edit the address/path of a CCN point in one of the following places in the WebCTRL® interface: The Details tab of a Point Properties dialog box The Address column on the Properties > Network Points page
Default Value | The value that the microblock outputs when communication with all specified targets fails or when Communications Enabled is not checked. The default value is used when the Valid? output is False (Off).
Editable | Check to make this microblock's value editable in the WebCTRL® interface.
Show Property Page Text | Check to show this microblock's value on the equipment's Properties page.
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.
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 ID | 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.
COV Increment | An Analog Network Input (ANI) that references this microblock in its Address field tries to subscribe to this microblock's COV (Change of Value) service. If subscription succeeds, the ANI receives a value from this microblock only when this microblock's present value changes by at least the COV Increment. If subscription fails, the ANI reads this microblock's value at intervals specified in the ANI's Refresh Time field.
#### Trends
Enable Trend Log | Check to have the controller collect trend data for the microblock's present value.
Sample every ___ (hh:mm:ss) | Records the microblock's present value at this interval. EXAMPLE Type `00:10:00` to record the microblock's present value every 10 minutes. NOTE Set this field in EIKON® to one minute or greater. After the control program is running in a live system, if needed you can adjust this setting in the live system based on the characteristics of the CCN bus and its polling interval. See "To collect trend data for a point" in i-Vu help, or see the CCN Integration Guide.
Sample on COV (change of value) | Records the microblock’s present value only when the value changes by at least the COV Increment.
Max samples | The number of data samples the controller allocates memory for. Memory consumption is 10 bytes for each sample plus 48 bytes. For example, for 100 samples: (100 x 10 bytes) + 48 = 1048 bytes of memory The allocated memory is constant regardless of how many samples are actually recorded. If you do not enable trending, no memory is consumed. NOTE Click Reset on the Properties page in the WebCTRL® or Field Assistant system to delete all samples currently stored in the controller.
Enable Trend Historian | Check this field to archive the controller's collected trend data to the system database after every 129 data samples. NOTES You must check Enable Trend Log if you want to Enable Trend Historian. You can change Enable Trend Historian archival settings and other trend properties on the Properties page in the WebCTRL® or Field Assistant system.
Keep historical trends for __ days | This is based on the date that the sample was read. Set this field to 0 to use the system default value.
Write to historian: Every ___ trend samples Use default (45% of Max samples) | Writes all trend data in the controller to the system database each time the controller collects the specified number of samples. You can select Every __ trend samples and enter a number greater than zero and less than the number in the Max samples field, or you can select Use default. The number of trends specified must be accumulated at least once before the historical trends can be viewed.
In the WebCTRL® or Field Assistant system only: |
Stop When Full | Check this field to stop trend sampling when the maximum number of samples is reached.
Enable trend log at specific times only | Collects trend data for the specific period of time you define in the time and date fields.
Store Trends Now | Writes all trend data in the controller to the system database without having to enable trend historian.
Trend samples accumulated since last notification | Shows the number of samples stored in the controller since data was last written to the database.
Last Record Written to Historian | Shows the number of trend samples that were last written to the database.
Delete | Deletes all trend samples stored in the database for the microblock.
BACnet Configuration | The Object Name is a unique alphanumeric string that defines the BACnet object. Although the Object Name field can be edited, it is not recommended. The Notification Class is set to 1 to receive alarms generated by Automated Logic® controllers.
#### Alarm
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.
Low Limit Enable | Check to send an alarm when the microblock's present value remains below the Low Limit value for the defined Delay Seconds.
Low Limit | The value the microblock's present value must drop below to send an alarm.
High Limit Enable | Check to send an alarm when the microblock's present value remains above the High Limit for the defined Delay Seconds.
High Limit | The value the microblock's present value must rise above to send an alarm.
Dead Band | The amount inside the normal range by which an alarm condition must return before a return-to-normal notification is generated. EXAMPLE
Delay Seconds | The time the microblock's present value must remain in an alarm condition before the microblock sends an alarm.
Return Enabled | Check to send a message when an alarm condition has returned to normal.
Fault Enabled | Check to send a message when a fault condition occurs, such as a misconfigured or non-existent sensor.
Alarm requires acknowledge | Check to require that an operator acknowledge alarm notifications on the system's Alarms page > View tab.
Return requires acknowledge | Check to require that an operator acknowledge return-to-normal notifications on the system's Alarms page > View tab.
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.
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.
#### Rnet NOTE These Rnet features work only in a UPC Open controller with a v6.04 or later driver and only in a v6.5 system with the latest cumulative patch or later system.
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 Static Pressure Setpoint (411), the sensor displays the setpoint, a target icon to indicate it is a setpoint, and the number 411 in the lower left corner to identify the value is a static pressure setpoint. NOTE If the Rnet tag droplist does not have the tag you want, you can create a custom tag in the EIKON® application.
Display Resolution | Defines the resolution of the value to be displayed on the ZS sensor. For example, 1 displays only integers (example: 74) and 0.5 displays values to the nearest 0.5 (example: 74.5).
Editable | Select to make this microblock's value editable on the ZS sensor. CAUTION Do not check this field if the microblock is being used for a status value.
Edit Increment | Select how much you want each press of the sensor's or button to change the microblock's value.
Minimum | Enter the lowest amount that this value can be changed to on the ZS sensor or in the WebCTRL® interface.
Maximum | Enter the highest amount that this value can be changed to on the ZS sensor or in the WebCTRL® interface.
ZS Sensor Display Configuration |
Show on: | Check the sensor screen(s) that you want this microblock's value 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 in EIKON® to define the order in which multiple microblock values will appear on each sensor screen.
