Scalable plant wide solution for machinery monitoring - An example of typical
hazardous area installation
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.
