SKF Multilog WVT System Overview

The SKF Multilog On-line System WVT (SKF Multilog WVT) unit is a compact, four-
channel vibration and temperature field-mounted monitoring device that communicates
on the ISA100.11a wireless standard. It also has a tachometer input to monitor the
speed of the machine. The device can be battery powered or powered from a DC
voltage source. It is ideal for monitoring machines in areas that are inaccessible, difficult
or dangerous to reach, or where it would be expensive or hazardous to install cables.
The digitizes dynamic machine condition analog signals using an on-board analog-to-
digital converter (ADC) and stores them in internal memory. This data is then passed
over the ISA100.11a network to a host computer, where it is automatically imported to
the SKF @ptitude Analyst software for viewing and analysis. The data can also be
imported to a Distributed Control System (DCS), such as Honeywell's Experion.
The network components of a system that supports SKF Multilog WVT devices are
shown in Figure 1-1. The SKF Multilog WVT is a field device which communicates
wirelessly with an access point known as a Field Device Access Point (FDAP). The FDAP
then communicates via a local field Ethernet network to a Wireless Device Manager
(WDM). The WDM has a second Ethernet network for passing data, for example, to a
host computer which will process and analyze the data. In this case, the host computer
would be running SKF @ptitude Analyst. The data can also be exported using the
available industrial protocols MODBUS, OPC and HART through the WDM.
A typical system consists of multiple SKF Multilog WVT devices and FDAPs with one
WDM managing the network. The ISA 100.11a standard allows for field devices to pass
data from one to another to an FDAP. When line powered field devices have routing
enabled, data "hops" from one field device to the next, thus increasing the overall range
of the network and reducing the number of FDAPs needed.
