Whether you're in IT, manufacturing, process control, facilities management or another key position in an organization, attaining the highest availability for critical equipment is a top priority. Realizing that goal takes thorough planning, careful design, superior equipment, proper installation and reliable power. To attain the highest availability of power, implementing a backup system including an Uninterruptible Power System (UPS) and a seamlessly integrated monitoring system is crucial. The Powerware Modbus Card is an X-slot connectivity device that provides continuous, reliable and accurate monitoring of a UPS through a Building Management System (BMS). The card uses the Modicon' Modbus RTU Protocol to integrate data from the UPS into many, widely used BMS packages such as Wonderware, Johnson Controls' Metasys' and Siemens' Apogee. Key power information may be monitored in real-time to aid in the diagnosis of problems. Included with the Modbus Card is the Profiler utility. Profiler creates a custom Modbus register map specifically tailored to the key parameters of the particular UPS. This makes it easy to integrate into a BMS. The output of Profiler is a .csv file that can be viewed with Microsoft Excel, if desired, then imported into a BMS. The Modbus Card connects to the network via RS-485 through either an isolated DB-9 port or terminal block. The terminal block allows conventional twisted pair cabling for daisy chaining. Alternatively, RS-232 Modbus communication via a DB-9 port may be used. The Modbus Card supports both two-wire and four-wire communication making it suitable for either topology. Also, because of its built-in, user-selectable termination feature, the Modbus Card may be placed at the end of the network. The Modbus Card conforms to the Powerware Xslot standard. This means that it supports a variety of UPSs that feature a native X-slot. It also supports other UPSs through the Powerware Expansion Chassis.
