SIPART DR20 Project Planning Manual
The device is switched to local mode with configuring switch positions 6 to 11, a CB switchover
from 0 to 1 and with front switch 13 in position "Remote". The computer coupling is only achieved
again by manual switching back to remote mode. The controller operates "With CB
acknowledgement".

Fig. 3/3 Digital functions via digital input/output and the serial interface (including status signals)
3.2.2 Input Signal Processing and Switchover
The following functions are explained in this section:
• Manual setpoint input w
i
or setpoint ratio w
v
• x-tracking
• Setpoint limiting and setpoint ramp
• Formation of negative deviation
• Alarm monitor
• Digital display of setpoint and actual value or the setpoint and actual ratio factor
and the limits
and, depending on the possible types of devices:
• Switchover and calculation of the setpoint w or the setpoint ratio factor
• Calculation of the controlled variable x
