5.6 Parameterization
Normally the configuration program provides an input box for the IO-Controler with
which the user can enter parameter data or select from a list. The structure of the
input box is stored in the device master file.
●
Danger of death, serious physical injury and/or damage to property
due to malfunction, caused by incorrect parameterization!

The system manufacturer must ensure correct functioning by carrying
out a protected test run during commissioning and after each parameter
change.

5.6.1.1 F_Check_iPar
The parameter is set to "NoCheck" and cannot be changed. This means the check
sum value is not evaluated about the iParameters.
