4 Function
4.1 Communication, parameter setting and evaluation
• The unit shows the current system pressure on its display.
• It generates 2 output signals according to the parameter setting.
OUT1
OUT2
•switching signal for pressure limit values.
•switching signal for pressure limit values.
•analogue signal for pressure (4...20 mA or 0...10V).
• It moreover provides the process data via IO-Link.
• The unit is laid out for fully bidirectional communication. So, the following op- UK
tions are possible:
-- Remote display: reading and display of the current system pressure.
-- Remote evaluation: transfer of switching signals (only with PP2001).
-- Remote parameter setting: reading and changing current parameter settings
with PP2001, FDT service program ifm Container or via IO-Link.
-- Using PP2001 and the FDT service program ifm Container, the current parameter settings can be stored and transferred to other units of the same type.
The program library of the available DTM objects can be found at www.ifm.com

4.2 Switching function
OUTx changes its switching state if it is above or below the set switching limits
(SPx, rPx). The following switching functions can be selected:
• Hysteresis function / normally open: [OUx] = [Hno] (→ fig. 1).
• Hysteresis function / normally closed: [OUx] = [Hnc] (→ fig. 1).
First the set point (SPx) is set, then the reset point (rPx) at the requested distance.
• Window function / normally open: [OUx] = [Fno] (→ fig. 2).
• Window function / normally closed: [OUx] = [Fnc] (→ fig. 2).
The width of the window can be set by means of the distance between SPx and
rPx. SPx = maximum value, rPx = minimum value.

P = system pressure; HY = hysteresis; FE = window
4.3 Analogue function
• [OU2] defines whether the set measuring range is provided as a 4...20 mA
signal ([OU2] = [I]) or a 0...10 V signal ([OU2] = [U]).
• The analogue start point [ASP] determines at which measured value the output
signal is 4 mA or 0 V.
• The analogue end point [AEP] determines at which measured value the output
signal is 20 mA or 10 V.
Minimum distance between [ASP] and [AEP] = 25 % of the span.
