Attached Probe Data Access
Access to the attached Smart Sensor register space for the USB and I2C interfaces uses a common memory
exchange mechanism that qualifies the access using the Omega Password and Omega Commissioning security
interface.
The IF-006-1 Configuration registers are only accessible thru the USB Modbus interface and are not subject to
security or password protection.
This architectural model allows the USB interface to directly configure the attached probe and prevents the access
of the Extension Space registers for any attached probes.
