1.2 SKF Multilog On-line System IMx-16Plus
The IMx-16Plus is a second generation
‘
IMx-8
’
capable of interfacing to 16 analogue
inputs (eight constant current accelerometers or voltage inputs and a further eight
that in addition have, PT1000 compatibility for temperature monitoring).
There are four digital inputs for speed, it is mobile data capable and has RS485 and
LAN interfaces. Note that mobile data and LAN (RJ45 or Wi-Fi) connectivity are all
alternative infrastructures to connect the IMx-Rail to the wider cloud network and
cannot be used simultaneously. Refer also
Installation and operating instructions
In an IMx-Rail device, it is supplied pre-fitted in the Rail enclosure and pre-wired to
the lid mounted antenna and to easily accessible user terminals, above the unit.
These encompass all the terminals available on the IMx-16Plus itself, such as
analogue inputs, digital I/O and RS485. The RS485 link can interface, by Modbus
RTU, to an external GPS module,
1.2.1 LTE/GSM (mobile) data module
A built-in module provides a wireless mobile data connection (LTE/GSM). It can work
world-wide and provides connectivity to @ptitude Observer software. Mobile data
functionality requires an activated SIM card or eSIM. The enclosure lid carries an
integral radio antenna, no connection to an additional, external antenna is required.
The choice between using a mobile data connection or a Wi-Fi/RJ45 LAN
connection, is part of the IMx-Rail configuration.
1.2.2 Local network RJ45 or Wi-Fi module
A built-in Wi-Fi module provides an 802.11n, Wi-Fi communication interface (2.4
GHz) so that, where available, a local train wireless network can be used as the first
stage of connectivity to @ptitude Observer software, rather than a hard-wired LAN or
the mobile network. Wi-Fi is combined in the lid mounted radio antenna, no
connection to an additional, external antenna is required.
1.2.3 GPS module (optional / external)
The IMx-Rail can use train position data to collate with the condition monitoring
measurements and to support the track monitoring functionality. The GPS data is
requested by the IMx-Rail, acting as a Modbus RTU master on the RS485, two wire
serial interface. Connections for this are available amongst the terminals provided.
An optional GPS module is available. This has an integral antenna, but the module
itself must be fitted external to the IMx-Rail enclosure.
