VersaSafe system

A-7.2
Downloading the configuration and parameter data
record
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 soft reset is performed
automatically (during which the D LED lights up).
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 IC220SDL963 with an old data
record.
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.
Important
Make sure that you are sending the correct data record to the correct IC220SDL963. If a
data record is sent to an IC220SDL963 for which it was not intended, an error message is
displayed in the diagnostic output of the handling block.
A-8
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”) i
n the image of the affected inputs to the affected logic module.
•
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.
A-9
Time response in the VersaSafe system
In the planning phase of the machine/system and the VersaSafe system, specify the
required shutdown time for each safety function. This is ascertained on the basis of the
safety evaluation of the machine/system, taking into consideration the safety distances
and the approach speed. Observe the applicable standards and regulations.
In the planning phase of the planned VersaSafe system, also calculate the shutdown time
for the outputs.
