Function and system design
Application
The Tank Side Monitor NRF590 is a field device for the integration of tank sensors into tank inventory systems.
It is used in tank farms, terminals and refineries.
Especially, it can be used in connection with Micropilot M level radars (for inventory control) and Micropilot S
high accuracy level radars (for custody transfer applications).
Operating principle
The Tank Side Monitor is typically installed at the bottom of the tank and allows to access all connected tank
sensors.
Typical process values measured by the sensors are:
• level
• temperature (point and/or average)
• water level (measured by capacitive probe)
• hydrostatic pressure (for hydrostatic tank gauging, "HTG", or hybrid tank measurements, "HTMS")
• secondary level value (for critical applications)
The Tank Side Monitor collects the measured values and performs several configurable tank calculations. All
measured and calculated values can be displayed at the on-site display.
Via a field communication protocol, the Tank Side Monitor can transfer the values to an inventory control
system.

Fieldbus Protocols
The Tank Side Monitor NRF590 supports all of the following industry standard communication protocols
allowing it to be integrated with existing instrumentation and connect to host computer systems without the
need for additional hardware. These protocols allow for piece-by-piece replacement and upgrading of older
technologies to modern radar solutions.
Sakura V1
V1 protocol provides a standard form of digital communication via a two-wire system. V1 was brought to the
market by Sakura Endress and meets the demands of the Japanese market.
The Tank Side Monitor implementation of the V1 slave protocol supports various old and new V1 protocols:
• V1 (new V1)
• MDP (old V1)
• BBB (old V1)
• MIC+232 (old V1) (in preparation)
EIA-485 (RS485) Modbus
In Modbus, the flow of data between two devices uses a master/slave protocol. The NRF590 acts as a Modbus
slave and runs on the EIA-485 (RS) version of the MODBUS communications board. Modbus provides Varec
MFT parameter mapping for easier setup in retrofit applications. It provides direct connection to PLC and DCS
systems.
Whessoematic WM550
The WM550 protocol provides a standard form of digital communication via dual current loops. WM550 was
developed by Endress+Hauser (formerly Whessoe) to facilitate communications to transmitters installed on
mechanical float and tape gauges. It is a two-wire system and the only protocol with a redundant loop.
BPM
The Bi-Phase Mark (BPM) protocol provides compatibility to Enraf systems by emulating the Enraf GPU-BPM
protocol. The NRF590 is fully compatible to ENRAF (802, 812), 811, 854 and 954 series servo gauges, 813
MGT (mechanical gauge transmitter), 872, 873 and 973 series Radar gauges, 874 AIM (Analogue Input
Module) and the 875 VCU (Valve Command Unit).
Mark/Space
The Mark/Space protocol provides compatibility with Varec transmitters using a standard form of digital
communication via a voltage mode bus. Mark/Space was developed to facilitate communication to transmitters
installed on mechanical float and tape gauges. It supports product level, temperature and discrete inputs.
L&J Tankway
L&J Tankway protocol provides a standard form of digital communication via a voltage mode bus. Tankway
supports product level, temperature and discrete inputs.
GPE
GPE protocol provides a standard form of digital communication via a current loop. It is compatible with L&J
and GPE mechanical float and tape and servo instrumentation.

Connection of the field
protocols
Sakura V1
The V1 protocol provides 2 wire communication allowing up to 10 devices to operate on a loop. V1 connects
to terminals 9-10.
Max. distance: 6000 m
EIA-485 Modbus
The NRF590 protocol uses a shielded 3-wire EIA-485 hardware interface to communicate with the modbus
master. EIA-485 is a high speed, differential communications network that allows up to 32 devices to operate
on one network.
• Using one shielded twisted pair of 18 AWG wire, connect the EIA-485 at terminal 9 and 10.
• Termination of the EIA-485 bus at the NRF590 can be set in the operating menu (only enable on end device
in a loop)
• Connect the 3rd wire from the control system signal common (0V) to terminal 8.
• Max distance: 4000 ft (1300 m)
Whessoematic WM550
The WM550 protocol provides 2 wire, current loop communication and allows up to 16 devices per loop. For
redundancy (safety function) two wire pairs are used. They always transmit the same values. The WM550loops connect to terminals 9 - 10 and 14 - 15.
Max. distance: 7000 m
BPM
The BPM protocol provides 2 wire communication allowing up to 10 devices to operate on a loop. BPM
connects to terminals 9-10.
Max. distance: 10000 m
Mark/Space
For a NRF590 using the Mark/Space field communications option, the following additional wiring connections
must be made:
• Run 2 twisted pairs (one power, one communication) of 18 AWG wire (Mark/Space wires) into the upper
terminal compartment through one of the conduit entries along with the 48 Vdc power wiring.
• Connect the Mark line to terminal 10 and the Space line to terminal 9.
• Connect to power supply at terminals 8 and 11.
L&J Tankway
Including power and ground, L&J is a 4-wire system, allowing 50+ devices to be connected on the
communication bus. L&J connects to terminals 8 through 11.
GPE
The GPE protocol provides 2 wire current loop communication. GPE connects to terminal 9-10.
Grounding of the fieldbus
screen
16
The screen of the fieldbus cable should be connected to ground at both ends. If this is not possible due to signal
disruption by potential equalisation currents, it is advisable to connect the screen of the fieldbus cable to
terminal "00 S" at the NRF590 and to ground at the other end. The "00S" terminal provides a 500 V capacitor
between the cable screen and tank ground potential.
Connection of the auxiliary
energy
The Tank Side Monitor can be AC or DC supplied, depending on the installed power supply board. The AC
supply needs to be connected to the terminals marked L/+ (Line) and N/- (Neutral), corresponding with the
phase/line and neutral wire. DC supply can be connected to the same terminals, for which it is necessary to
connect the positive (+) to the terminal marked (L/+), and the negative to the terminal marked (N/-).
Connection of the non-i.s.
4 ... 20 mA analogue input
Depending on the selected fieldbus communication board, a non-i.s. self-powered or loop powered analogue
transmitter can be connected. The analogue signal for the loop powered transmitter can be connected to the
terminals 14 (-) and 15 (+24 Vdc). The maximum supply current for the analogue transmitter is limited to 24
mA. The analog signal for a self powered transmitter should be connected to terminals 11 or 12 and 14.

Connection of the non-i.s.
4 ... 20 mA analogue output
For all field communication boards except the Modbus Option without analog in/output, a
non-i.s. 4.. .20mA output is available. Via Software settings, this analogue output can be connected to any
parameter in the Tank Side Monitor. The analogue output is available between terminals
13 (+) and 12 (-). From SW 02.01.xx onwards, an additional HART signal is available at terminal 13.
Connection of the discrete in
and output
The Tank Side Monitor can be equipped with up to 2 discrete I/O modules. These modules can be used for
interfacing to non-i.s. discrete in- or outputs. Input and output voltage and current ranges depend on the type
of selected module installed in the relevant I/O slot. Terminals 4 and 5 correspond to discrete I/O slot A,
terminals 6 and 7 correspond to discrete I/O slot B. For details on available I/O modules, see Page 32.

Tank sensors
The Tank Side Monitor can interface to a maximum of 6 i.s. HART sensors.
All HART sensors are connected to one HART multi-drop communication loop.
In order to keep wiring simple, 3 interconnected terminal pairs are available. The terminal pairs are marked
respectively H+ and H-.
Power supply for Micropilot S
For supplying extra i.s. power to the FMR S-series radar, additional power terminals are available, marked as
P+ and P-. Although it is possible to use only 3 wires between the S-series radar and the NRF590, by combining
the P- and H- wires, it is recommended to use a double pair of screened and twisted cable.
Grounding of the cable screen (for Micropilot S)
The screen of the cable connecting the Micropilot S to the Tank Side Monitor should be grounded at the Tank
Side Monitor, not at the Micropilot S.

HART sensors
The data of connected HART sensors is constantly scanned and updated in the internal data base. The scanning
sequence is based on the priorities of the measurements (level - prio 1, temperature - prio 2, pressure - prio
3,...). Typically, a value change on the HART multidrop loop is displayed after a 2 seconds delay (for priority 1
values).
Spot RTD input
RTD resistance is measured and recalculated at least every second.

Operating concept
The Tank Side Monitor is operated via a four-layer menu. The structure of the menu accounts for typical
measuring tasks as well as for the individual instrument configuration and installation. In particular, the menu
contains dynamic function groups which are only indicated if the respective option is installed or the respective
instrument is connected. This structure ensures clarity and simple operation without restricting the scope of
functionality.
The appearance and meaning of the LCD change according to the current position within the menu.
