Digital communication (terminal 97 / 98)
• PROFIBUS PA in acc. with IEC 61158-2 (PA+ / PA-)
U = 9 ... 32 v, I = 10 mA (normal operation), I = 13 mA (in the event of an error / FDE)
Bus connection with integrated protection against polarity reversal
The bus address can be set via the DIP switches in the device (with dual-compartment transmitter housing only), the transmitter
display or the fieldbus.
or
• FOUNDATION fieldbus in acc. with IEC 61158-2 (FF+ / FF-)

Digital output DO2 (terminals 41 / 42) (pulse output or digital output)
Function can be configured locally as "Pulse Output" or "Digital Output" using software.
Factory setting is "Digital Output", flow direction signaling.
The output is always a "passive" output (optocoupler).
