Operation
Note:
If the address is set to 0 or a value greater than 125 (decimal), the RED error LED will flash at 1 Hz and the
module will go on-line or 1 the RED error LED will flash at 1 Hz and the module will go on-line. If this occurs
either, change the address and cycle the power or remove power and change the address.
4.5
Baud-rate
All 10 standard DP baud-rates are supported. These are: 9.6kBd; 19.2kBd; 45.45kBd; 93.75kBd; 187.5kBd; 500kBd;
1.5MBd; 3MBd; 6MBd; 12MBd. The unit has no facility for adjusting baud-rate as detection is automatic, and it will
therefore respond to the baud-rate chosen by the master.
4.6
Software format
The Slave software is based upon a modular configurable architecture so the user has considerable control of the
contents of the Data exchange messages.
The software modules (defined in the GSD files) relate to the controller serial communications objects.
When the unit is linked onto the Profibus it will be parameterised and then configured before entering data exchange.
The configuration choices are in the GSD file and its comments describe the data content of the input and output
bytes. These choices will often be made using a third party configurator such as SyCon that presents a user-friendlier
interface.
16-bit values are transmitted with the MSB first and the LSB last.
