7.3.6
Preventing unintended or unauthorized modification
To prevent unintentional modification, configuration of the device is only allowed via
SOPAS ET and the SiLink2 master required for this. The output of the sensor must be
connected directly to the SiLink2 master. This means that if modification of the device
parameters is desired, the device must first be disconnected from the application. The
device can then be connected to a computer on which SOPAS ET is installed via the SiL‐
ink2 master. The system integrator is responsible for ensuring that this is only done by
authorized and also instructed personnel. The system integrator is also responsible for
checking whether further measures are required to prevent unauthorized modification.
