Operation
EL6910 120 Version: 1.8.0
TwinSAFE Logic in PreOP state
If Customizing is carried out on a TwinSAFE Logic with EtherCAT status PreOP, the customizing of
a group does not become active. Customizing must be carried out again if the TwinSAFE Logic is in
the EtherCAT status SafeOP or OP.
4.15 Saving the analog group inputs persistently
EL6910, EJ6910 and EK1960 support persistent saving of analog input values in an internal memory. When
the group starts up, the stored data are compared with the current data. Under the tab
Max Start Deviation, a
corresponding deviation can be specified for each defined analog input value of the group.
Fig. 170: Specifying deviations for analog input values
In the group properties the general settings for setting substitute values and checking the analog values on
group startup can be parameterized. Setting the parameter
Verify Analog FB Inputs at Group Startup to
TRUE activates saving of all analog group inputs.
