They feature a variety of software-configurable digital and analog inputs and outputs and are suitable for installation at strategic locations throughout your buildings. The modules convert physical input signals from sensors into network variables and the network variables into physical output signals for operating actuators. [. . . ] Transmitted immediately when its value has changed more counts than defined in "Send on Delta". Regularly transmitted as a heartbeat output. After power-up and reset, the value 0xFFFF=65535 will be sent to the network to indicate to the receiving device that previous count values have been lost due to a reset. Transmitted immediately when the digital input state has changed. Regularly transmitted as a heartbeat output as dictated by nciSndHrtBt. It is stored in the configuration parameter file accessible using standard LONMARK mechanisms. Used to define the properties associated with a digital input. Represents the current status of the analog output, including feedback related to manual override initiated from either nviAoManOvrd or the manual override switches. Typically used for monitoring purposes at supervisory stations or for diagnostic purposes. In the case of an override, the state is equal to -1. Used to drive the analog output to 0. . . 100%. Typically bound to a LONWORKS control device issuing an output level 0. . . 100%. A value of 110% is also possible (corresponding to a voltage range of 0. . . 11 V). Typically bound to a LONWORKS control device issuing an output level 0. . . 100%. A value of 110% is also possible (corresponding to a voltage range of 0. . . 11 V). Used to manually override the analog output to 0. . . 100%. Has priority over nviAoSwitch and nviAoValuePct. Typically used during start-up and commissioning, supported by the XILON Handheld MMI, and does not have to be bound. If the relay is at present manually overridden, this will be reflected in nvoAoActPosnFb, accordingly. The manual override remains in force until explicitly reset to normal operation via power-up and reset. This state is therefore stored in EEPROM. If there has been a manual override to the same output, this will have priority over nviAoManOvrd. [. . . ] This layout allows for maximum bus length, and its simple structure presents the least number of possible problems, particularly when adding on to an existing bus. For more information, please refer to http://www. echelon. com Analog Outputs Each module is equipped with two analog outputs providing either 0. . . 11 VDC, 0. . . ±1. 1 mA signals or 0. . 20 mA/4. . 20 mA signals (model-dependent). Each analog output features an extra power output terminal for supplying 24 Vac power to actuators. The analog outputs have a permissible load of > 10 kOhm, and a typical accuracy of ±0. 2 V. Other Module-Specific Features / Options Manual Overrides and Status LEDs The XFC1D06, the XFC2D05 and XFC2D06, as well as the XFC3D04, 3D05, and 3D06 are each equipped with six 3position (ON, OFF, AUTO) manual override sliding switches with which the individual digital/analog output signals can be overridden.
