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 VFD 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 VFD related GSD files (device data files) information,
users can obtain type definition file (GSD) of master machines from local INVT agent.
