1.6 Product recycling/disposal

Recycling of equipment and packaging should be taken into consideration and disposed of in accordance with local and national legislation/regulations.

1.7 Packing material

Rosemount Tank Radar AB is fully certified according to ISO 14001 environmental standards. By recycling the corrugated paperboard, or wooden boxes, used for shipping our products you can contribute to take care of the environment.

Reuse and recycling

Experience has shown that wooden boxes can be used several times for various purposes. After careful disassembly the wooden parts may be reused. Metal waste may be converted.

Energy recovery

Products which have served their time may be divided into wood and metal components and the wood can be used as fuel in sufficient ovens.

Due to its low moisture content (approximately 7%) this fuel has a higher calorific value than ordinary wood fuel (moisture content approximately 20%).

When burning interior plywood the nitrogen in the adhesives may increase emissions of nitrogen oxides to the air 3-4 times more than when burning bark and splinter.

Note

Landfill is not a recycling option and should be avoided.

2.4 System overview

The Rosemount Tank Gauging system is a state-of-the art inventory and custody transfer radar tank level gauging system. It is developed for a wide range of applications at refineries, tank farms and fuel depots, and fulfills the highest requirements on performance and safety.

The field devices on the tank communicate over the intrinsically safe Tankbus. The Tankbus is based on a standardized fieldbus, the FISCO integration of any device supporting that protocol. By utilizing a bus powered 2-wire intrinsically safe fieldbus the power consumption is minimized. The standardized fieldbus also enables integration of other vendors’ equipment on the tank.

The Rosemount Tank Gauging product portfolio includes a wide range of components to build small or large customized tank gauging systems. The system includes various devices, such as radar level gauges, temperature transmitters, and pressure transmitters for complete inventory control. Such systems are easily expanded thanks to the modular design.

The Rosemount Tank Gauging system is a versatile system that is compatible with and can emulate all major tank gauging systems. Moreover, the well-proven emulation capability enables step-by-step modernization of a tank farm, from level gauges to control room solutions.

It is possible to replace old mechanical or servo gauges with modern Rosemount Tank Gauging devices, without replacing the control system or field cabling. It is further possible to replace old HMI/SCADA-systems and field communication devices without replacing the old gauges.

There is a distributed intelligence in the various system units which continuously collect and process measurement data and status information. When a request for information is received an immediate response is sent with updated information.

The flexible Rosemount Tank Gauging system supports several combinations to achieve redundancy, from control room to the different field devices. Redundant network configuration can be achieved at all levels by doubling each unit and using multiple control room work stations.

Reference Manual

2.4.1 TankMaster HMI software

Rosemount TankMaster is a powerful Windows-based Human Machine Interface (HMI) for complete tank inventory management. It provides configuration, service, set-up, inventory, and custody transfer functions for Rosemount Tank Gauging systems and other supported instruments.

Rosemount TankMaster is designed to be used in the Microsoft® Windows environment providing easy access to measurement data from your Local Area Network (LAN).

The Rosemount TankMaster WinOpi program lets the operator monitor measured tank data. It includes alarm handling, batch reports, automatic report handling, historical data sampling as well as inventory calculations such as Volume, Observed Density and other parameters. A plant host computer can be connected for further processing of data.

The Rosemount TankMaster WinSetup program is a graphical user interface for installation, configuration and service of devices in the Rosemount Tank Gauging system.

2.4.2

Rosemount 2460 System Hub

The Rosemount 2460 System Hub is a data concentrator that continuously polls and stores data from field devices such as radar level gauges and temperature transmitters in a buffer memory. Whenever a request for data is received, the system hub can immediately send data from the updated buffer memory for a group of tanks.

Measured and calculated data from one or more tanks is communicated via the Rosemount 2410 Tank Hub to the system hub buffer memory. Whenever a request is received, the system hub can immediately send data from a group of tanks to a TankMaster PC, or a host.

The Rosemount 2460 can be used to connect devices from other vendors as well, such as Honeywell® Enraf and Whessoe.

The Rosemount 2460 has eight slots for communication interface boards. These boards can be individually configured for communication with hosts or field devices. They can be ordered either for TRL2, RS485, Enraf BPM or Whessoe 0-20 mA/RS485 communication. Two slots can also be configured for RS232 communication.

One of the system hub’s three Ethernet ports is used for Modbus TCP connection to host systems. By simply connecting the system hub to the existing LAN network, communication over Ethernet is established.

The system hub can provide redundancy for critical operations, by using two identical devices. The primary system hub is active and the other one is in passive mode. If the primary unit stops working properly, the secondary unit is activated and a failure message is sent to TankMaster (or a DCS system).

Advanced port configuration window

The Advanced Port Configuration configuration to a non-standard configuration. This is a useful option if, for example, the Rosemount 2460 System Hub is connected to a host system that requires manual port configuration. Then you can configure protocol and communication parameters to match the requirements for the host. Non-standard settings may also be needed in case field devices connected to different field ports use different communication parameters such as baud rate. Then each port can be configured independently from the other ports.

Non-standard settings may also be required in case the system hub is located far away from the host since maximum communication speed for RS232 and RS485 depends on the cable length.

Some emulation protocols use the same type of modem card. Therefore, you may need to specify communication protocol and configure parameters for the particular protocol to be used.

Reply timeout and Number of retries

Min/max response time

Min Rx to Tx delay time

Single Port Mode

Redundant field ports

For Field Ports the Reply timeout and Number of retries parameters can be adjusted in case a connected field device responds slowly to queries from the Rosemount 2460. The default setting is sufficient in most cases.

For Host Ports the Min response time and Max response time define the time slot in which a response from the Rosemount 2460 will be sent to a host system. If needed, you may change these parameters to match the requirements for a particular host system.

For field ports a delay time between receive and transmit messages can be used for devices that need more time to get ready to receive the next query e.g. TIC devices.

In case of cross talks between field port buses, it is possible to configure affected ports to be silent while communication is ongoing on a port in single port mode. For the configuration to have an effect, two or more field ports must be enabled for Single Port Mode. If all field ports are enabled for Single Port Mode, no concurrent communication among the field ports can occur at all. This configuration has no effect if the Port is configured for host mode which is an option for ports 5 and 6.

The Redundant Field Ports functionality is supported for TRL2 and RS485 interface and requires license for redundant system hubs. Two field ports can be configured in a redundant primary/backup pair. If the primary port has communication problems, the backup port will take over after a number of retries. Status of the passive port is checked at regular intervals. A switch over to backup port will only take place if status of the backup port is OK. If the backup port is active, and primary port status is back to normal, a switch over will take place once the status check is done.

Redundant field ports can be used with redundant Rosemount 2460 System Hubs.

(5) Some modems must be configured with DIP switches.

70 Reference Manual

Reference Manual Configuration

00809-0100-2460 September 2021

2. Select the appropriate Source device.

For a Rosemount Tank Gauging system this is typically a Rosemount 2410 Tank Hub. The Rosemount 2460 System Hub also supports many other Rosemount Tank Gauging devices as well as devices from other vendors.

3. Select the Field Port that the device is connected to.

In the standard configuration there are six field bus ports available for a Rosemount 2460 System Hub. The TRL2 bus is the standard field bus interface.

4. Enter the 2410 Device Address for each Rosemount 2410 Tank Hub that is connected to the system hub.

Note

Note that for 2410 Tank Position 1 the same address will be used for the temperature device and the tank hub itself. This is handled automatically by TankMaster.

5. Enter the appropriate 2410 Tank Position.

All field devices on a certain tank are associated with the same position in the Rosemount 2410 Tank Hub’s tank database. For a Rosemount 2410 connected to a single tank, all field devices are configured in Tank Position 1.

Use Tank Position 2-10 for the multiple tanks version of the Rosemount 2410 Tank Hub. It has a database with 10 tank positions that allows the tank hub to serve up to ten tanks. Each row in the tank database of the Rosemount 2460 System Hub corresponds to a tank position in the database of the Rosemount 2410 Tank Hub.

Important

The Tank Database of the Rosemount 2460 System Hub must be properly configured to match the tank databases of all Rosemount 2410 Tank Hubs connected to the system hub.

6. Enter Level Device Address for devices such as the Rosemount 5900 Radar Level Gauge and other level gauges supported by the Rosemount 2460 System Hub and the Rosemount 2410 Tank Hub.

7. In case the level gauge is a Rosemount 5900S 2-in-1 version, you will need to configure two level device addresses.

See the Rosemount Tank Gauging System Configuration Manual (Document No. 00809-0300-5100) for a detailed description of how to configure the tank database for a Rosemount 5900S Radar Level Gauge 2-in-1 version.

Rosemount 2460 System Hub 71

Configuration Reference Manual

September 2021 00809-0100-2460

8. Enter the Temperature Device Address.

For “2410 tank position” 1 the same address is used for the Rosemount 2410 Tank Hub and the temperature device. The tank hub’s address is automatically copied to the Temperature Device Address field.

For “2410 Tank Position” 2 to 10 you will have to enter the same temperature device addresses as configured in the Rosemount 2410 Tank Hub’s tank database. Each tank position must have a unique address.

Note

The Temp Device Address in the Rosemount 2460’s tank database is referred to as the ATD Modbus Address in the Rosemount 2410 Tank Hub’s tank database.

9. Enter the number of elements in the Number of Temperature Elements column in case temperature elements are installed in the tank.

The position of the temperature elements need to be configured to allow calculation of average product temperature. This is normally done as part of the standard installation procedure for the Rosemount 2410 Tank Hub and the associated temperature transmitters as described in the Rosemount Tank Gauging

System Configuration Manual (Document no. 00809-0300-5100).

10. Select the Auxiliary Inputs that are used for the device such as Free Water Level (FWL), Vapor Pressure (VP), and Liquid Pressure (LP).

11. In the Relays column, select 2410 if a Rosemount 2410 Tank Hub with relay output is connected to the Rosemount 2460 System Hub. Then the 2460 input registers will be continuously updated with current status of the 2410 relay outputs. Leave empty if no relays are used.

Note

Ensure that the Tank Database is properly verified before proceeding. Check all addresses and parameters for each tank and source device.

Note

Once all devices and tanks are installed and configured, the position of a device in the Tank Database may not be changed, since this will result in corrupt mapping of tank to Tank Database position.

Level device address

The Level Device Address field in the tank database of the Rosemount 2460 System Hub is used for level gauges such as the Rosemount 5900. This address also needs to be stored in the tank database of the Rosemount 2410 Tank Hub.

Normally, address configuration is done as part of the installation procedure of the Rosemount 2410 as described in the Rosemount Tank Gauging System Configuration

Manual (Document No. 00809-0300-5100).

Temperature device address

The Temperature Device Address in the tank database of the Rosemount 2460 System Hub is a common address for all devices (ATD) on a tank except level gauges. The Temperature Device address also needs to be stored in the tank database of the Rosemount 2410 Tank Hub. For the tank hub this address is referred to as the ATD Modbus address.

Configuration of the Rosemount 2410 tank database is normally done as part of the installation procedure of the Rosemount 2410 as described in the Rosemount Tank Gauging System Configuration Manual (Document No. 00809-0300-5100).

4.3.4

Tank databases of the Rosemount 2460 and the Rosemount 2410

In a typical Rosemount Tank Gauging system, a Rosemount 2460 System Hub collects measurement data from a number of tanks via one or more Rosemount 2410 Tank Hubs. For proper communication with the control room PC and the Rosemount TankMaster operator’s interface, Modbus addresses need to be assigned to the field devices on the tank. These addresses are stored in the system hub’s and tank hub’s tank databases.

Rosemount 2460 System Hub 81

Configuration Reference Manual

September 2021 00809-0100-2460

In the tank hub’s database, the Rosemount 2240S Temperature Transmitter and the Rosemount 2230 Graphical Field Display (and other non-level devices) are handled as a single Auxiliary Tank Device (ATD). Two Modbus addresses are used for each tank, one for the level gauge and one for the ATD.

The ATD includes any supported non-level device such as the Rosemount 2240S MultiInput Temperature Transmitter and the Rosemount 2230 Graphical Field Display. Other devices such as the Rosemount 3051S Pressure Transmitter may also be included in the ATD. The ATD address represents all these devices. Each position in the Rosemount 2460 tank database represents one tank.

In case the level gauge is a Rosemount 5900S 2-in-1, you will need to configure two level device addresses for the Rosemount 5900S gauge. See the Rosemount Tank Gauging

System Configuration Manual (Document No. 00809-0300-5100) for a detailed

description of how to configure the tank database with a Rosemount 5900S 2-in-1.

One Rosemount 2410 Tank Hub for each tank

In this example a Rosemount 2460 System Hub is connected to two tanks, each of which has a separate Rosemount 2410 Tank Hub.

Each tank has a Rosemount 5900S Radar Level Gauge, a Rosemount 2240S Multi-Input Temperature Transmitter, and a Rosemount 2230 Graphical Field Display. The Modbus address configuration is summarized in Table 4-14.

Multiple tanks connected to a single Rosemount 2410 Tank Hub

In this example a Rosemount 2460 System Hub is connected to a Rosemount 2410 Tank Hub that serves three tanks. The temperature device on tank 1 has the same Modbus address as the tank hub itself. The other temperature devices on tank 2 and 3 have separate Modbus addresses.

Figure 4-7 shows an example of a system with a Rosemount 2460 System Hub connected

to a Rosemount 2410 Tank Hub. The Rosemount 2410 collects measurement data from three tanks. Each tank is equipped with a Rosemount 5408 Radar Level Transmitter, a Rosemount 2240S Temperature Transmitter, and a Rosemount 2230 Graphical Field Display. The Modbus address configuration is summarized in Table 4-15.

Maximum number of fail-overs per hour in order to prevent an oscillating behavior i.e. switching back and forth between Primary and Backup device. In case fail-overs tend to occur frequently, the reason behind should be investigated and fixed.

Take-over criteria

There may be situations when you would like the passive device to take over as the active device even if no fail-over criteria is fulfilled. For example, in case the active device does not respond to Host requests, the passive device may take over and become the active device. The Active doesn’t reply on Host port option does not work if the Primary and Backup system hubs are wired to separate host ports which is the case when, for example, using the RS232 communication interface.

Passive device communication

In case the Primary and Backup system hubs are connected to different ports on the host system, the same Modbus address can be used for communication with the two system hubs. Then there is no need to use individual Modbus addresses for the Primary and Backup devices. When communicating with a host system via RS232 interface, separate host ports must be used, and the Allow Passive device to reply on common Modbus address option needs to be enabled.
