P157: Polarity with which the signal in Volt can be generated by analog output 1
on terminal 8
P158: Polarity with which the signal in Volt can be generated by analog output 2
on terminal 10
0:Bipolar. Bipolar range.
1:Positive only. Unipolar range, only positive in the two above mentioned
outputs.
This parameter is active only if the signal set on the analog output is a voltage
signal (-10 ... 10V) (jumper JP409 and/or JP4010 in pos. 1-2). If a current signal
(0 ... 20mA) (jumper JP409 and/or JP4010 in pos. 2-3) is to be brought to the
output at issue, polarity may not be defined, as the current direction is the one
outgoing from the terminal towards zero volt
