Table 52: Technical data: PROFIBUS-DP interface: interfaces and communication
Controller PROFIBUS controller VPC3+, 12 Mbaud max.
Protocol PROFIBUS-DP, 32-byte telegrams with operating-mode-depending configuration
Interface Floating, D-SUB 9-pin, integrated bus terminating resistors (can be activated by
DIP switches)
Special functions Support of diagnosis data, RTS signal led out, fail-safe mode, sync/freeze
The following elements can be found on the front plate of the PROFIBUS-DP interface
(see
Figure 30
):
a green LED to indicate that the bus is ready for operation
a 9-pin female DSUB connector
two DIP switches for activating the terminating resistors
