Read/Write Device - SLG U92 with FCC
Version: 01.00 of 19.09.02
A&D SE PS 3, R. Völler
Description
The SLG U92 is a read/write device with integrated antenna for long range applications. It is designed
especially for the automotive industry and industrial production plants. It uses the transmission frequency
of 2.4 GHz of the worldwide approved ISM frequency band. This permits transmission distances from just
a few centimeters to up to three meters with a very low sending power of < 50 mV/m at distance of 3 m
and high net transmission speeds of up to 8 Kbytes per second. Transmission frequency, robust modula-
tion procedures and check routines can be selected so that electromagnetic interference can be disre-
garded, and error-free data transmission and integrity are still ensured. The antenna field of the SLG can
be activated and deactivated via function call or automatically with a proximity switch during communica-
tion with an MDS.
MOBY U technology stops familiar interference during UHF transmissions such as reflection, interfer-
ence and over-the-horizon transmissions.The specially designed antennas provide a homogeneous
transmission field and ensure 100% detection of mobile data memories (MDSs). This makes expensive
shielding and antenna setting unnecessary.
With its mobile data memories MDS U524 and MDS U589 (up to +220° C, cyclic) and 32 Kbytes of stor-
age space, MOBY U meets the prerequisites for a transparent solution in the automotive industry.
The SLG U92 offers inexpensive system integration via coupling to:
• Proven MOBY interface modules (ASM) for PROFIBUS-DP-V1 and SIMATIC S7
• Directly to standard PC, SICOMP or PC-PLC
Software tools such as the SIMATIC S7 functions (FC) and C library (MOBY API) for applications under
Windows 98/NT make implementation in the particular application simple.
The powerful but easy-to-use filehandler with logical file addressing which we all known from MOBY I is
directly integrated in the SLG U92 with expanded functionality. The commands MOVE and LOAD from
the MOBY I filehandler are a thing of the past. The SLG always fetches the required file management
information directly from the MDS. MOBY U can be run in three stages.
1. MOBY U can be run with standard settings, with unchanged filehandler functions and without the
MOVE and LOAD commands for existing system solutions with MOBY I.
2. Only a few expanded commands are required for changes in the standard settings and the require-
ments of diagnostic data.
3. Full utilization of MOBY U performance. In this stage, the commands and/or user data can also be
securely assigned to the particular MDS number.
In addition to filehandler mode, the MDSs can use direct byte addressing as with the other MOBY identi-
fication systems.
A separate service and diagnostic interface makes it simple to commission and trouble-shoot during
operation. In addition, this interface can be used with the service function "load software to SLG" in exist-
ing applications for future function expansions without having to exchange the SLG.
