Conveyor and Warehouse Control
dhPlus is affordable conveyor and warehouse control for small to medium size systems.
Overview
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, dimensioners 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.
The latest version is 1.11.
Pricing
Turnkey pricing for dhPlus deployments range from about $50K to $1M. It is more cost effective than all of the large system integrators and many of the smaller ones.

What's included
The best way to think about dhPlus is as a customizable hardware and software product that will control a customer's conveyor system. It has two main options — Flex and Custom. Flex is our standard distributed configuration while Custom has traditional control panels and caters to customer special requests. See the Feature Matrix below.
dhPlus typically ships with the following:
- One or more control pedestals (for Flex) or traditional control panels (for Custom) with high capability PLCs (Programmable Logic Controller) to control the conveyor system.
- One or more HMIs (Human Machine Interface) mounted on the pedestal or control panel door. The HMIs are used to control and monitor the conveyor system.
- One or more industrial PCs for the WCS (Warehouse Control System) mounted in the pedestal or control panel. The PCs have battery backup and do not run Windows for added security and reliability.
- Field devices such as photo eyes, proximity switches, E-stop pull cords, pushbutton stations, air pressure sensors and motor disconnect switches. For Flex, motor starters and VFDs are also field mounted.
Optional equipment that can be shipped with dhPlus include barcode camera stations, dimensioners, P&A (Print and Apply) units, and a maintenance support laptop. See simplified architecture diagram below.
