Data Communications
The open PROFIBUS/DP network enables
extremely fast data exchange with a very
wide variety of slave devices, including:
Remote digital I/Os
Remote intelligence PLC
(FX0N, FX2N)
Frequency inverters (FR-A 024/044,
FR-A 240 and MELTRAC 140)
Operator terminals (MAC)
A range of other devices from third-
party manufacturers
Structure
The maximum coverage of a bus segment
is 1200 m (at a maximum of 93.75 kbit/s).
Up to 3 repeaters are allowed. Thus the
maximum distance between 2 stations is
calculated with 4800 m.
Cable types
To help reduce costs PROFIBUS/DP uses
RS-485 technology with simple twisted-
pair cabling.
Suitable cables include the UNITRONIC
BUSLD from Lappkabel and the DUE 4451
from Alcatel.
Data exchange
The PROFIBUS AJ71PB92 and
A1SJ71PB92D master modules support
slave device data exchange with up to
32 send bytes and 32 receive bytes. This
means you can exchange a total of up to
64 bytes with a slave unit per network
cycle.
Administration
In combination with the MELSEC Profi-
Map configuration software the
A1SJ71PB92D PROFIBUS/DP master unit
gives you user-friendly plug-and-play
technology. The configuration software is
self-explanatory, using a graphical model
for setting up the network. You simply se-
lect the slave unit (e.g. FX2N), assign the
station numbers and specify where the
information is stored in the Master CPU.
Of course, PROFIBUS/DP slaves from
MITSUBISHI ELECTRIC can also be con-
nected to master devices from other
manufacturers.
