30 Interfaces Supported by Dearman’s Terminal Automation System



The purpose of a terminal automation system is to integrate field devices into a single system via process control so operators can easily move and track product. The more devices that are integrated, the greater level of automation can be achieved.


Device integration also helps terminal companies to utilize data for reporting as well as practical business functions such as automatically billing their customers according to contracts.


At Dearman, we strive to make our terminal automation systems as flexible and open to integration as possible. Here are 30 popular terminal field devices that we integrate with.


Please note that this is not an order of preference or ranking.

11 - Fairbanks Scale

Fairbanks offers a variety of truck scales including the “Talon Steel Deck” and the “Talon Field Pour”.


According to the product listing, “Fairbanks’ Talon steel deck scales offer a choice in capacity and deck plate thickness. For normal duty-cycles, the HV with ¼” deck plate is a solid performing scale. In “extreme” duty-cycles, the HVX offers 3/8” deck plate for a more robust solution.”



According to the product listing, “Concrete provides extraordinary life even in the most aggressive applications. The Talon HV offers a 10” thick concrete deck while the HVX offers a 12” thick concrete deck. Depending on your application and duty-cycle, Fairbanks has a Talon field poured concrete scale design that will maximize the lifespan of your scale.”


Dearman is mostly agnostic to the model of the scale. To integrate with our terminal automation system, we need the constant stream of data coming from the weight indicator. The weight indicator needs to have an Ethernet and/or serial communications option.



12 - Mettler Toledo Scale

Mettler Toledo offers a variety of truck scales with steel decks or concrete decks. These scales use “POWERCELL load cell technology to provide proven performance and exceptional durability” and “use the proven design of orthotropic ribs”.


Again similar to the Fairbanks scales, Dearman can interface with a wide variety of models. Dearman needs a constant stream of data coming from the weight indicator/electronic scale head.

22 - PLCs – Any That Supports MODBUS® RTU (Serial or TCP/IP)

Dearman integrates with various PLCs (Programmable Logic Controllers) that are available from Siemens, Allen-Bradley (Rockwell Automation), Automation Direct, and other vendors.



What is a PLC? And what is the difference between serial protocol and TCP/IP protocol?

A PLC (Programmable Logic Controller) is a ruggedized, solid state industrial computer "adapted for the control of manufacturing processes such as assembly lines, robotic devices, automation processes, or any activity that requires high reliability, ease of programming, and process fault diagnosis". PLCs can range from micro/small devices (like the ones in Dearman’s DEU) with only a handful of inputs and outputs (I/O), to large rack-mounted modular devices with thousands of I/O.


PLC's may be programmed to perform hundreds or even thousands of of tasks at any given terminal. Dearman integrates with PLCs that support MODBUS RTU (serial or TCP/IP).
