8.1.4 Network interface card slots
The communications interface board contains two card slots that can be used with a range of network interface cards to
interface the UPS system with a building management system or computer network. A suitable network interface card can
be chosen to enable the UPS to be monitored and interrogated by one of following protocols:
• Simple Network Management Protocol (SNMP)
• MODBUS over TCP/IP
• MODBUS over RS-485
SNMP is a world-wide, standardised communication protocol and the one that is used most often to integrate the UPS with
a wider building/network management system. It can be used to monitor any network-connected device via a simple
control language and display the results in an application running within a standard web browser.
An SNMP/Ethernet adapter card contains an RJ-45 connector which can be connected to the network using a standard
CAT-5 cable. Once connected, the UPS-Management software agent which is already installed in the SNMP adapter can
monitor the UPS operation and output its data to the connected network in SNMP format. In a parallel module UPS system
such as the PW8000DPA ST the SNMP interface can communicate ‘system-wide’ data or data for an individual UPS
module.
The SNMP adaptor card requires a PC with terminal connections and, for normal operation, at least one Ethernet
connection. The SNMP card enables event/alarm email traps, server shut down (with optional licenses) and other tasks;
and can also be integrated with BMS software over a local area network (LAN) for SNMP or Modbus information over IP.
Alternatively, SNMP connectivity can be implemented using an external SNMP adapter connected to the communications
interface board RS232 output (JD1), as shown in Figure 8.6.
