## Carrier microblocks The following Carrier microblocks allow the WebCTRL® application to communicate directly with CCN devices.
| CCN Controller A CCN Controller microblock does the following: Establishes and verifies communication with a CCN device in the CCN network. Contains the CCN device address so that all CCN points in the control program can link to it. Determines the refresh time for these related CCN points. Write points use standard network microblocks that have individual refresh timers.
| Carrier Binary Value The Carrier Binary Value microblock can monitor and force (restrict) a binary value in a Carrier device.
| Carrier Analog Value The Carrier Analog Value microblock can monitor and force (constrain or restrict) an analog value in a Carrier device.
| Carrier Binary Point The Carrier Binary Point microblock reads the binary (on or off) value of a physical input on the controller and makes this value available to be read by other BACnet devices on the network. The value appears to other BACnet devices as the Present Value property of a BACnet Binary Input Object.
| Carrier Analog Point 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).
| BACnet CCN Alarm The BACnet CCN Alarm microblock monitors CCN alarms and passes them from the Carrier device to the WebCTRL® Alarms page or third-party BACnet front end.
| Carrier Schedule The Carrier Schedule microblock writes a weekly schedule to the CCN Controller.
| Carrier Schedule with TLO and Override Status This microblock reads schedules from the WebCTRL® or Field Assistant system and generates signals to tell the control program whether or not the zone is occupied and how long the zone will remain in its current state. The microblock writes a weekly schedule to the CCN Controller.
| Zone Setpoint for Integration This microblock determines a zone's heating and cooling setpoints for both occupied and unoccupied periods.
| Carrier Setpoint The microblock compares the zone temperature to the zone's effective setpoint to determine the zone thermographic color that represents the control program status. Other microblocks (such as the If Color = microblock) can use this color to perform additional control. It also passes the programmable setpoints to the control program's associated CCN controller.
| Carrier Text Display This microblock lets you display text for a CCN point on a Properties page or Graphics page.
