transmission distance there are two kinds of fiber optical conductors, one is low-cost plastic
fiber conductor, used distance is less than 50 meters, the other is glass fiber conductor, and
used distance is less than 1 kM.
A.2.6.5 PROFIBUS bus connection diagram
Above is "terminal" wiring diagram. Cable is a standard PROFIBUS cable consisting of a
twisted pair and shielding layer. The shielded layer of PROFIBUS cable on all nodes is
directly grounded. Users can choose the best grounding method according to the situation.
Note:
Make sure that signal lines do not twist when connecting all stations. Shielded cable should
be used when system runs under high electromagnetic interface environment, which can
improve electromagnetic compatibility (EMC).
If using shielded braided wire and shielding foil, both ends should be connected to ground.
Using shielding area should be large enough to maintain a good conductivity. And data lines
must be separated from high-voltage.
Stub line segment should not be used when transmission rate more than 500K bit/s, The
plug is available on the market which connects directly to data input and output cable. Bus
plug connection can be on or off at any time without interruption of data communications of
other station.
A.2.7 System configuration
1. Master station and inverter should be configured so that the master station can
communicate with the module after correctly installing EC-TX-103 communication card.
Each PROFIBUS subsidiary station on the PROFIBUS bus need to have "device description
document" named GSD file which used to describe the characteristics of PROFIBUS-DP
devices. The software we provided for the user includes inverter related GSD files (device
data files) information, users can obtain type definition file (GSD) of master machines from
local INVT agent.
