Description
(Visible when 114.01 Module 1 type
Defines the real value that corresponds to the maximum
analog input AI3 value defined by parameter
max. See the drawing at parameter
min.
Real value corresponding to maximum AI3 value.
(Visible when 114.01 Module 1 type
The value of the analog output can be overridden for eg,
testing purposes. A forced value parameter
force data) is provided for the analog output, and its value is
applied whenever the corresponding bit in this parameter is
1.
Value
1 = Force AO1 to value of parameter
Reserved.
Forced values selector for analog outputs.
(Visible when 114.01 Module 1 type
Displays the value of AO1 in mA.
This parameter is read-only.
(Visible when 114.01 Module 1 type
Selects a signal to be connected to analog output AO1.
Alternatively, sets the output to excitation mode to feed a
constant current to a temperature sensor.
None.
The value is taken from another parameter.
(Visible when 114.01 Module 1 type
Forced value that can be used instead of the selected
output signal. See parameter
(Visible when 114.01 Module 1 type
Defines the filtering time constant for analog output AO1.
