00813-0100-2460, Rev CA May 2020 Rosemount™ 2460 System Hub for tank gauging systems Transfers tank gauging data to Rosemount TankMaster™, Host and DCS systems ■ Ensure fast data update rate ■ Serves up to 64 tanks ■ Benefit from scalable options for all system sizes ■ Get real-time inventory calculations with API standard net volumes ■ Get flexible and configurable multiple port connectivity ■ Achieve instrument and system redundancy ■ Enable other vendor emulation by bringing in data from gauges such as Enraf®, Varec®, and Sakura

Efficient update of vital online tank data The Rosemount 2460 System Hub is a data concentrator that continuously polls and stores data from field devices such as radar level gauges, pressure and temperature devices. 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 system hub also supports connection of other tank gauging instruments such as TankRadar™ Pro and TankRadar Rex gauges. In addition, it can be used to connect devices from other vendors, such as Honeywell® Enraf, Whessoe, etc. Figure 1: System Overview Rosemount TankRadar FBM 218 0 Ext. pwr RS-232 USB Tx Rx Lo - GAIN - Hi On - TERM - Off C A HE I H F B D G J L K M A.

Configurable multiple port connectivity The Rosemount 2460 has eight slots for communication interface boards. These boards can be individually configured for communication with hosts or field devices. The Rosemount 2460 supports a number of host communication interface standards such as Ethernet, TRL2, RS485, and RS232. For field communciation TRL2 and RS485 are supported, as well as other standards such as Enraf BPM and Digital Current Loop (Whessoe). Modbus TCP communication to host 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: ■ Easy access, no special converters required ■ Fast communication ■ No need for dedicated cabling ■ Can be connected to TankMaster or other hosts User-defined Modbus mapping The Rosemount 2460 can easily be integrated into existing hosts as it can be configured to match the existing value mapping of the current system. It provides flexibility when replacing legacy devices as it can be set up to match the old device without configuring the host system. Figure 2: User-Defined Modbus Mapping C A B D A.

Improved system reliability with redundancy The system hub can provide redundancy for critical operations by using two identical devices. The primary system hub is in active mode 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). Redundancy can be utilized for some or all equipment in the system from the control room to the field devices. Redundancy is supported on field level as well by using two field devices connected to the same tank for hot redundancy of field values. It can be a Rosemount 5900 2-in-1, two separate Rosemount 5900 devices, or two separate devices of different types. Field port redundancy is supported where two field ports can be connected in a ring network where one acts as a hot backup. All field ports are available for redundancy. It is also possible to use redundancy individually on ports 1-2, ports 3-4, or ports 5-6. Figure 3: Redundancy B AA C C D D B A. TankMaster client PCs B. Switch C. TankMaster servers D.

Seamless integration of gauges from other vendors Replace your old tank management system with Rosemount TankMaster by connecting the system hub to the existing field devices, such as Enraf, Whessoe, or Varec. Rosemount TankMaster can seamlessly replace an existing inventory management system, still being able to communicate with the field devices in use. This often enables a better update rate than before. Emulation also enables the step-by-step modernization of a tank farm by replacing old field devices with Rosemount 5900 level gauges, temperature devices, and one or several tank hubs. Any Modbus field device that communicates via RS485 Modbus RTU can be integrated into Rosemount 2460. Up to three device types can be defined.

Real-time inventory calculations include gross and net volumes as well as mass calculations, according to current API tables (6, 54, 24, 60, A-D) and ASTM D4311. Tank Capacity Tables (5000 strapping points per tank/table) are supported for cylindrical and spherical tanks. Net Standard Volume can be calculated at a user-specified reference temperature for specific tables. Figure 5: Inventory Calculation A B C I J L K D E F H G A. Level B. Tank Capacity Table C.

(2) Depending on device type and application, the number of devices per tank, or number of tanks per device, may differ. (3) Dual Rosemount 2460 System Hub redundancy requires two system hubs with identical model codes. For redundant systems with emulation,consult factory for technical guidance. (4) This option is required to be able to use field port redundancy and/or field device redundancy. Field port redundancy is only possible for TRL/2 and RS485 ports, where the same interface must be used on each pair. The capacity of the Rosemount 2460 is reduced when using field port redundancy. (5) When using Modbus TCP in combination with user-defined Modbus mapping, the same Modbus mapping will be used for all clients. In this case, TankMaster cannot be used. (6) See Table 2 for maximum number of devices connected to each field port. (7) Not supported for redundant system hubs (Redundancy option code R). (8) External power supply is required for powering the bus. (9) Only one protocol can be used per port. (10) Empty ports will not be enabled for use. To activate an empty port after delivery, a port upgrade must be ordered. (11) Emulation of Enraf CIU 858 for connection to existing host system or service/configuration tool.
