16.3.2.4 Channel type

Name:
X1CfO_AI_Mode
This register defines the type and range of signal measurement.
Each channel is capable of handling current, voltage or resistance signals. This differentiation is made using differ-
ent terminal connections and an integrated switch. The switch is automatically activated depending on the specified
configuration. The following input signals can be set:
Input signal
±10 V voltage signal (default)
0 to 20 mA current signal
4 to 20 mA current signal
PT1000 measurement
Resistance measurement
Data type Values
USINT See the bit structure.
Bit structure:
Bit Description
0 - 2 Analog input - Channel 1
3 Reserved
4 - 5 Analog input - Channel 2
6 - 7 Reserved
