Parameterization and programming
ELX3202 and ELX3204 42 Version: 1.4.0
Fig. 30: ELX3202 - not connected setting
By means of a double click on the corresponding object 0x80n0:1A [
}
53] , the respective channels can be
switched off in the Set Value Dialog by selecting the Enum value not connected ; see fig. not connected
setting.
5.1.4 Programmed characteristic sensor curves
Direct resistance measurement
The ELX320x can be used for direct resistance measurement in three measuring ranges (n = channel 0...3)
CoE setting 0x80n0:19 [
}
53]
Measuring range Resolution/digit
0x101 0 ... 6,553.5 Ω 0.1 Ω
0x102 0 … 0.650.535 Ω 1 Ω
0x103 0 ... 240,000 Ω 10 Ω
Notice: The way in which the ELX320x measures is electrically the same with these three settings. Only the
displayed resolution is changed in the firmware. The full-scale value is therefore 240 kΩ for all three
measurements.
Fixed characteristic sensor curves
Further programmed characteristic sensor curves in the defined measuring range can be selected
individually in the CoE entry
0x80n0:19 [ } 53] for each channel (n = channel 0...3).
