Channel use
If only one channel of a "configuration pair" is used (e.g. channel 0 and 1), then
the other channel must be connected with a resistor (e.g. 120 Ω Pt100 meas-
uring range, 1200 Ω Pt1000 measuring range). Otherwise an error message is
indicated.
NOTICE!
Temperature-dependent resistors
Other temperature-dependent resistors cannot be used for the replacement
device.
NOTICE!
Thermocouples type J, type K, type S
Thermocouples cannot be evaluated with the replacement device. The respec-
tive section in the existing documentation (incl. figure 5.2-6) is not valid for
device 07AI91.
Configuration for unused channels
See existing documentation 07AI91 System description Advant Controller 31.
Relationship between the measuring values and the location of the bits in
a 16 bit WORD
– The measuring ranges
±
500 mV and
±
50 mV no longer exist.
– Measuring range
±
5 V:
– Replacement device: 11 bit resolution plus sign
– Existing device: 12 bit resolution plus sign
– All measuring ranges for thermocouples are no longer available.
1.5.3.2.5 Addressing
In the following, the information in the "Type" column refers to the data type designation of the
Automation Builder (see AC31 system data
Ä
Chapter 1.3 “System data and CS31 bus system
data” on page 4). The information in the "Type" column must be interpreted from the viewpoint
of the CS31 bus master. The information in brackets must be interpreted from the viewpoint of
the replacement device (CS31 bus slave).
The function of the address DIP switch 8 (channel No.
£
7 or channel No. > 7) is
no longer supported.
