BACnet® the MS/TP communication module allows MULTICAL® meters to be integrated into a building automation system or to be part of industrial installations. The module is compatible with the BACnet® standard. Application The BACnet® module is designed with a high flexibility focus to meet a wide range of applications. The BACnet® module supports rapid exchange of meter data, e.g. flow, energy and temperatures to facilitate monitoring and control tasks. Analysis MULTICAL® energy meters support high quantities of data, and all data relevant for analysis can be read out. Alarms The MULTICAL® info codes for general alarms, flow errors, temperature errors, water leakage, very high flow, air in the system and incorrect flow direction are available to the BACnet® system. Control and regulation The module supports Change Of Values (COV). This is part of BACnet® event notification. BACnet® clients, such as PLC’s, can subscribe to changes to values in the MULTICAL® variables. This feature results in quick response times, which are necessary for alarms and control purposes. Installation The module is easily mounted on a free module space in the meter. A configuration may be required if a specific BACnet® MAC address is required. Configuration of BACnet® MAC address, Object name and Object identifier, can be performed with METERTOOL HCW through the MULTICAL® optical eye or through the 10-pole connector on the module. " The module is supplied via the meter’s internal 230 VAC or 24 VAC power supply. 2 Kamstrup A/S • FILE100000529_B_EN-58101538_D1_09.2023
