Namur Basic Information - Beckhoff EL3182 Documentation

The password protection is provided for following user data
Protect-able CoE object
0x80n0:17 (User Calibration Offset)
0x80n0:18 (User Calibration Gain)
0x80nD:17, (Low Range Error)
0x80nD:18 (High Range Error)
Application of CoE 0xF009
• Insertion of 0x12345678 activates the password protection → object indicates '1' (switched on)
Protected objects can no longer be changed; there is no error message by a write access!
• Insertion of 0x11223344 deactivates the password protection → object indicates '0' (switched off)
Code word index 0xF008
This CoE object has simply a vendor specific task and is not dedicated for the user.

NAMUR basic information

The abbreviation of NAMUR, "User Association of Automation Technology in Process Industries" identifies
an international association for users of automation technology that considers the interests related to
standardization, devices and measurement control (or similar) of the Process Industries as its major task. In
this role, the NAMUR releases the so called NE (proposed standards), each numbered continuously.
Information with regard to the implementation of this recommendation in Beckhoff products are specified in
sections "Technical data" and "Process data" of this documentation.
Analog measured values
The analog output value of a sensor that can be measured among other things as a certain current value
represents the measurement information (M).
By means of NAMUR NE43 a recommendation – irrespective of the sensor manufacturer – for standardized
failure information (A) is defined in addition to the measurement information (e.g. malfunction of a
measurement converter, error in connective wires, failure of an auxiliary energy etc.). The failure information
states that there is an error in the measuring system. This concerns the analog output signal of sensors in a
current loop and therefore in the form of a current value. A current value lying outside of the limits defined by
NAMUR is defined as invalid and is thus interpreted as failure information. The following diagram illustrates
this:
