12.4 System components
Advanced Data Manager
Memograph M
The Advanced Data Manager Memograph M is a flexible and powerful system for
organizing process values. The measured process values are clearly presented on
the display and logged safely, monitored for limit values and analyzed. Via
common communication protocols, the measured and calculated values can be
easily communicated to higher-level systems or individual plant modules can be
interconnected.
For details, see Technical Information TI01180R/09
RN221N
Active barrier with power supply for safe separation of 4-20 mA standard signal
circuits. Offers bidirectional HART transmission.
For details, see "Technical Information" TI00073R and Operating Instructions
BA00202R
RNS221
Supply unit for powering two 2-wire measuring devices in the non-Ex area.
Bidirectional communication is possible via the HART communication jacks.
For details, see "Technical Information" TI00081R and Brief Operating
Instructions KA00110R

Failure information
Failure information as per NAMUR NE43:
Failure information is created if the measuring information is missing or not valid. A
complete list of all the errors occurring in the measuring system is created.
Underranging
Linear decrease from 4.0 to 3.8 mA
Overranging
Linear increase from 20.0 to 20.5 mA
Failure, e.g. sensor breakage, sensor short-
circuit
≤ 3.6 mA ("low") or ≥ 21 mA ("high"), can be selected
The "high" alarm setting can be set between 21.5 mA and
23 mA, thus providing the flexibility needed to meet the
requirements of various control systems.
