4.4.8.9.3 Analog output - Configuration
4.4.8.9.3.1 Setting the channel type
Name:
ConfigOutput01
This register can be used to set the channel type of the outputs.
Each channel is capable of handling either current or voltage signals. The type of signal is determined by the
connection terminals used. Since current and voltage require different adjustment values, it is also necessary to
configure the desired type of output signal. The following output signals can be set:
•
±10 V voltage signal (default)
•
0 to 20 mA current signal
Data type
Value
USINT

4.4.8.9.4 Analog output - Configuration
4.4.8.9.4.1 Output values of the analog outputs
Name:
AnalogOutput01 to AnalogOutput04
These registers provide the standardized output values. Once a permitted value is received, the module outputs
the respective current or voltage.
Information:
The value "0" disables the channel status LED.
