4.11.3 Sample program for parameterizationIn the following sample
program the parameter data are received, stored in the PLC as
persistent data, resent to the EL6910 whenever the device
starts up, and stored in CoE object 0x8005.
Saving PROFIsafe parameters persistently
The safety parameters for the slave connection transferred by the PROFIsafe master to the EL6910
are only transferred once when the PROFIsafe master starts up. On restart of the EL6910 these pa-
rameters would not be transferred again, so that the stored data have to be transferred again. If this
is not done, the master must be restarted when the slave restarts.
