5.2 Analog output EM- S1OUTA
5.2.1 General
The analog output of the EM-IO-02 expansion module is a volta
g
e output with a ran
g
e
of +/-10 V. Parameterization of the output signals is done by the definition of the op-
eration mode and a linear characteristic, stating the offset and the amplification.
5.2.2 Operation modes
The operation mode of the analog output is selected via the parameter
Operation
mode
584.
Additional to the operation modes listed, those stated in the operatin

Example of the adjustment of the analog output:
Note: The measurements for the adjustment are to be done with a suitable
measuring instrument and the correct polarity.
T

the adjustment.
If not, faulty measurements and settings can result.
Select operation mode "0 – Off“ for the parameter
Operation mode 584.
Enter the voltage measured on the output in the parameter
Adjustment

Select operation mode "100 - 10 V“ for parameter
Operation mode 584.
Enter the voltage measured on the output in the parameter

Select operation mode "0 – Off“ on the parameter
Operation mode 584. In case
the volta

nificantly, carry out the
adjustment procedure again.
Note: The greatest precision to be achieved is approx. +/-40 mV.
