Conveyor and Warehouse Control



dhPlus is affordable conveyor and warehouse control for small to medium size systems. It can be used for a wide range of conveyor applications and can utilize many field devices including barcode scanners, weigh scales and P&A (Print and Apply) units.

dhPlus can also communicate with host systems such as SAP for intelligent package routing and tracking through the warehouse or plant.


Turnkey pricing for dhPlus deployments range from about $40K to $500K. It is more cost effective than all of the large system vendors and many of the smaller ones.

What's in the box?

The best way to think about dhPlus is as a customizable hardware and software product. It has two main options -- Standard and Enterprise. See the Feature Matrix below. 

dhPlus typically ships with the following:

  1. Control panel with high capability PLC (Programmable Logic Controller) and motor controls such as starters and VFDs which are used to control the conveyors.
  2. HMI (Human Machine Interface) mounted on the control panel door or on a separate pedestal. The HMI is used to control and monitor the conveyor system.
  3. Field devices such as photo eyes and motor disconnect switches

Optional equipment that can be shipped with dhPlus include a PC workstation (Enterprise option), barcode cameras, P&A units, additional HMI pedestal stations and a maintenance support laptop.


The feature matrix below outlines all of the main hardware and software features. Specifically, the Enterprise option requires a PC server running Windows or a customer supplied VM (Virtual Machine).
