Safety Note
If more than one F-CPU is accessible over a network (such as MPI) from one
programming device or PC, you must take the following additional measures to
ensure that the safety program is downloaded to the correct F-CPU:
Use passwords specific to each F-CPU, such as a uniform password for the
F-CPUs having the respective MPI address as an extension: "Password_8".
Note the following:
• A point-to-point connection must be used the first time a password is assigned
to an F-CPU (this also applies to the first time an MPI address is assigned to
an F-CPU).
• Before downloading a safety program to an F-CPU that has not yet been
assigned access protection with an F-CPU password, you must first revoke
existing access permission for any other F-CPU.
