8810 Remote Terminal Unit
The 8810 Remote Terminal Unit (RTU) is a modular, Ethernet ready, communications device. Its powerful industrial chassis is ideal for integration with tank gauges and other field devices used in inventory management applications. With support for up to six interface modules, it is extremely flexible in handling data exchange across multiple communication protocols.
First shipment date is estimated to take place on or before September 30, 2019.

Next Generation Communications Device
With the CPU module serving as the base functionality for the 8810 RTU, all logic and protocols are handled seamlessly, meaning there is only one firmware application for the entire unit.
The standard, built-in OPC Unified Architecture (OPC UA) server communicates natively over standard internet protocols. This allows human machine interface (HMI) applications to read data from the 8810 RTU. It is also compatible with a wide range of systems, including legacy Varec systems, using RS-232 and RS-485 standards.
8810 RTU Key Features:
- Ethernet ready, provides high-speed communications in near real time
- Integrates with legacy tank gauging protocols
- Industry standard OPC UA
- Modbus for host or field integration
- Supports both Modbus TCP and Modbus over TCP
- Supports up to 400 tanks
- Supports up to 27 communication channels
- Digital input/output for alarms, monitoring, and control
- Intelligent scanning based on tank activity
- Includes the Vertue browser-based configuration application
VeRTUe RTU Utility
The 8810 RTU comes with its own configuration application. Vertue is intuitive, extremely user-friendly and browser-based.
VeRTUe Key Features:
- Standard with 8810 RTU for configuration
- Intuitive browser-based user interface
- Optimized for bulk liquid applications
- Configure using any workstation on the network
- Efficiency tools for common actions
- Supports offline configuration
- Pre-configured or customized diagnostics
Add-on Modules
Four add-on modules* are available as options in the first release: Serial, Bi-Phase Mark, Digital I/O, and Mark/Space.
Serial Module:
- Any serial channel can be configured for Modbus Slave or Master protocols
- Easy integration and retrofit through mappings that mimic other systems
- Support for user mappings of Modbus registers to 8810 RTU tags and parameters
- Standard Modbus mappings allow external hosts to connect and retrieve data without impacting the current 8810 RTU configuration
- Supports Enraf using a CIU
- Used for both host and field functionality
- Supports legacy 8130 RTU protocol
Digital I/O Module:
- Logic and digital signal processing implemented in CPU module
- Includes eight ports for interfacing with digital I/O circuits
- Nine combination of inputs and outputs on a single eight channel module
- Supports integration of digital signals such as alarms
- LED indicators provide visual status of each port
Bi-Phase Mark Module:
- Supports connection and communication to Honeywell Enraf Bi-Phase Mark loops
- Provides four interface ports per module
- Each port includes two termination plugs
- Two terminal plugs per port allows gauging loops to be combined into one channel
- Two terminal plugs allow a connection point for a test gauge or transmitter without disturbing an existing loop
- LED indicators provide visual status of each port
Mark/Space Module:
- Integration to Varec devices, i.e. model numbers 1800, 1900, 4000, 2910, and 2920
- Supports GSI 2000 M/S transmitters
- Two independent Mark/Space channels
- Supports high speed and low speed Mark/Space transmitters
- Flexible power distribution as each channel can be independently powered by the 8810 back plane or an external power supply
- Each channel has a replaceable fuse
- LED indicators denotes status for each channel, i.e. transmit, receive, power selection/fuse, and bus failure
- 2500 V(rms) isolation for each channel from field to internal electronics
*Future modules currently under development.
Integrates with HMI Applications
The 8810 RTU can be integrated with a variety of human machine interface applications. FuelsManager, a suite of software applications used to track, manage and control the receipt, storage, distribution and delivery of fuel and related products, has built-in functionality for easy integration with the 8810 RTU. Examples of other supported HMI manufacturers include Honeywell, Rockwell Automation, Emerson and Wonderware.
