Function:
Holds the preset level of terminal X42/7.
In case of a bus timeout and a timeout
function is selected in 26-50 Terminal
X42/9 Output the output will preset to this
level.
Function:
Set the function of terminal X42/9.

Function:
Scale the minimum output of the selected
analog signal at terminal X42/9, as a
percentage of the maximum signal level. E.g.
if a 0 V is desired at 25% of the maximum
output value. Then programme 25%. Scaling
values up to 100% can never be higher than
the corresponding setting in 26-52 Terminal
X42/9 Max. Scale.

26-52 Terminal X42/9 Max. Scale
Range: Function:
100.00 [0.00 - Scale the maximum output of the selected analog
% 200.00 signal at terminal X42/9. Set the value to the
*

Scale the output to give a voltage lower than 10V
at full scale; or 10V at an output below 100% of
the maximum signal value. If 10V is the desired
output current at a value between 0-100% of the
full-scale output, programme the percentage
value in the parameter, i.e. 50% = 10V. If a voltage
between 0 and 10V is desired at maximum
output, calculate the percentage as follows:
