4.5 Downloading the safety-related configuration
4.5.1 Via the TR SNCT tool – SafetyOpen Type 2
The user must always validate all downloads to the measuring system.
A download of the safety-related configuration requires that the measuring system has a TUNID and
that a communication has been established to the TR SNCT tool TR SNCT Device Applet.
Before downloading the configuration to the measuring system, verify that the correct measuring
system receives the preset configuration. To do so, use the SNCT’s verification option Device ID.
The safety-related measuring system parameters
SIL / PL
Direction of rotation
Measuring range
Revolutions numerator
Revolutions denominator
Velocity format
Velocity factor
Velocity integration time
Velocity filter type
Velocity filter strength
Window Increments
and the calculation/determination of the Safety Configuration CRC SCCRC and Safety Configuration
Time Stamp SCTS are set/performed by the SNCT Safety configuration function.
The combination of SCCRC and SCTS serves as a clear ID of the set configuration and makes up the
Safety Configuration Identifier SCID.
Once the settings have been made as required, press the button Calculate to calculate this
configuration. The result is displayed in the fields SCTS: and SCCRC. Right-click in the relevant field to
copy the calculated value to the clipboard to then paste it in the originator’s engineering tool.
The configuration must be downloaded to the measuring system so the preset
configuration can be tested and verified.
Switch to the SNCT function SNCT Download to meet this requirement. The previously calculated
SCTS and SCCRC values are automatically applied and written into the corresponding fields of the
Configuration Download section.
The Download button transfers the preset configuration to the measuring system, which applies it
after a voltage OFF/ON cycle.
Now the measuring system is configured and the originator can put it into the cyclic data exchange
(Execute State) state.
