Analog output
12.2 Analog output
By default the 1st analog output (either cable at A2 or internal P0-6) is used to
output the measured value for the selected measuring point and the 2nd ana-
log output (internal P0-7) is used to output the measured value for the 1st
channel of the selected sensor; (see 11.2, Manual 6.10.7).
Selecting the reference channel
However, which channel is in fact to be output via which analog output can also
be stipulated by the user. To do this the parameters ´
ACh1
´, ´
ACh6
´, or ´
ACh7
´
must be configured as previously described.
Scaling the analog output
The output signal from each analog output variation (0 to 2 V, 0 to 10 V, 0 to 20
mA, 4 to 20 mA) can be set for each sensor to any partial range (e.g. 4 to 20
mA for -30.0 to +120.0 °C). For the previously specified reference channel, the
values for analog output start and analog output end plus analog output type (0
to 20 mA or 4 to 20 mA) can all be programmed.
First the analog output must be selected and then
the
reference channel
can be programmed (e.g.
M01); (see above) :
