Downloading the configuration and parameter data record
following power up
The entire configuration and parameterization can be created offline with VersaConf
Safety. A fully installed system is not required until the download stage. Communication
must be running when transmitting the data record.
A 10 Safe state
The safe state
– For safe output devices, the safe state is the power off state at the affected output
terminals
– For safe input devices, the safe state is the transmission of the "safe state value" ("0")
in the image of the affected inputs to the safe standard control system
– For transmission on the bus, the safe state is the transmission of the value "0"
The safe state can be a normal operating state or is set if a corresponding error has been
detected.
WARNING: Loss of safety function
Before downloading a data record, check whether the current data record is actually
loaded.
Make sure that you do not overwrite the data record on the IC220SDL953 with an old data
record. Information about a data record is provided in the project header.
During startup, do not configure a delete service for a configuration and parameter data
record. Before overwriting a data record, always read back the project header first.
Make sure that you are sending the correct data record to the correct IC220SDL953. If a
data record is sent to a IC220SDL953 for which it was not intended, an error message is
displayed in the diagnostic register of the IC220SDL953.
Function blocks can be downloaded for selected controllers.
