System Overview
User Manual, Revision F
System Overview
IMx-T is a part of the SKF Multilog On-line System product range. IMx-T is the next
generation of powerful, cost-effective solutions for a variety of condition monitoring
applications.
In conjunction with SKF @ptitude Observer or Analyst software, Multilog IMx-T provides
a complete system for early fault detection and prevention, automatic advice for
correcting existing or impending conditions and advanced condition-based maintenance
to improve machine reliability, availability and performance.
Figure 1-1: System overview, IMx-T with @ptitude Observer/Analyst
The picture above illustrates how IMx-T units are linked together in a network that is
connected via a LAN (it can also be a modem or GPRS router) to a @ptitude Observer
Monitor or Analyst IMx Service. The @ptitude Observer Monitor or Analyst IMx Service
in turn can be connected to e.g. a LAN network making it possible for several of
@ptitude Observer or Analyst clients to link to this network.
@ptitude Observer or Analyst clients can also be installed on the same computer as
@ptitude Observer Monitor or Analyst IMx Service login software. Through a general
interface, also known as ODBC (open database connectivity), it is possible to link
@ptitude Observer Monitor or Analyst IMx Service login computer to an existing
database for an existing control or processing system, if desired. The @ptitude
Observer Monitor or Analyst IMx Service, @ptitude Observer or Analyst clients and the
database can be separated from each other as long as they are on the same network
where ODBC calls can travel freely.
It is also possible to connect different types of on-line units in the same network, for
example, IMx-T together with IMx-S and/or MasCon systems.

Among other things, consider lengths of cables, where electrical power to the IMx-T
units can be connected, where should @ptitude Observer Monitor or Analyst IMx Service
be installed and positioned and who should analyse the data measured. Good and
thorough planning is the basis for a successful solution and installation.
Make a detailed layout of the equipment, the network, and distances between
components. Include specifically the IMx-T units, the @ptitude Observer Monitor or
Analyst IMx Service computer, the database server computer and all hubs/routers in the
network. Specify network configuration of each components, such as IP addresses and
subnet masks. SKF application engineers and service engineers need these information
in order to assist.
Note that a CAT5/6 twisted pair (TP) Ethernet cable has maximum working distance of
100 m. If longer cable lengths are needed, fibre optic cables may be used along with
needed converters such as converters for fibre optic to CAT5/6 (TP) Ethernet and vice
versa.
When GPRS is used, the GPRS routers should be reconfigured as a part of the
application to run a lifeline connection with the @ptitude Observer Monitor or Analyst
IMx Service computer.
Warning - Failure of this communication path will force the GPRS router to reboot itself
constantly, and can hamper the success of the application. This is especially valuable to
consider when the GPRS forms a part of the customers internal IP network (VPN). In
such case, SKF must be informed of this before ordering the GPRS, so that SKF can
disable the lifeline functionality of the GPRS router.
