Fieldbus connection via PROFIsafe
Startup
The scaling factor used must also be taken into account to ensure that the safety
controller uses the same unit as that of the DCS21B option to further process the
position value.
Position = position in controller × scaling factor
Position = 10 000 × 1000 = 1 000 000 mm/10 = 100 000
6.7.4 PROFIsafe process image
The status of the safety functions sent via PROFIsafe can be read in MOVISAFE
®
Config by choosing [Process Diagnostics] / [Safety Bus] / [PROFIsafe] / [Process
Image] (see below figure).
The process image for PROFIsafe includes a subset of the process image of the
DCS21B. The process input and output data have 64 bits each according to PROFIsafe
requirements:
• 32 bits (data type: BOOLEAN) for input/output states and the safety functions
• 32 bits (data type: double integer) for position value
INFORMATION
•The Pos_Factor for internal scaling depends on the chosen encoder settings. The
factor is handled solely by the DCS21B option and can not be set separately.
• As scaling disregards decimal places, the accuracy of the transmitted values
changes. Keep this in mind for further processing.
