PERATING PRINCIPLES
PROFIBUS DP is a 2-wire industrial data communication standard (Field bus) which allows automation components
like sensors, actuators and controllers to exchange information.
Simple PROFIBUS system.
PROFIBUS DP is a master / slave bus system. Bronkhorst instruments are all slaves. There is no mutual communication
between PROFIBUS DP slaves, only between a master and slave. Each slave must have its own unique station address
on the bus, otherwise there is no communication possible. Setting slave station address can be performed by either:
• Via rotary switches (Non industrial instruments)
• Master configuration software.
For example:
• Sycon V2.6.2. from Hilscher G.m.b.H. (in this manual)
• Step 7 V5.1 from Siemens for PLC type S7-300 2DP.
Most master configuration software tools work in the same way, because PROFIBUS DP is a standardized field
bus system. Only on details and program operation things could be different.
Read user manual carefully for correct operation of other programs than Sycon and Step 7.
• Bronkhorst tooling software: eq FlowFix
The Bronkhorst tooling software is able to communicate with the instrument via RS232 using a special cable. If
you don’t have such a cable ask your local sales representative.
• Via Micro-switch and Led’s
PROFIBUS DP slaves using, will adapt automatically to baud rates determined by the master on a bus
segment.
