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.
Full Integration with Building Management Systems
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 Modbus 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.
Flexible Network Connections
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.
Selectable Communication Topologies
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.
Support for a Wide Range of UPS's
The Modbus Card conforms to the Powerware Xslot standard. This means that it supports a variety of UPS's that feature a native X-slot. It also
supports other UPS's through the Powerware Expansion Chassis. |
