Project Scope

Jake Davis, Product Engineer for De Dietrich Process Systems, Inc contacted us for help with a redesign of the Powder Pump. The Powder Pump is a dense-phase pneumatic conveying system that eliminates the need to manually handle solids and minimizes other potential hazards by providing a closed system to transfer materials such as powders, prills, granules, flakes, etc. in a safe and contained manner.

The Powder Pump operates via a series of pressure and vacuum valves that turn on and off in an automated sequence to manage the transfer and flow of powder from the source equipment to the receiving vessel. The proposed application utilizes a Maple Systems 7.0" touchscreen with an integrated IO module.

  1. Develop the PLC program for the Maple Systems HMI+PLC that meets the functional requirements as described by the customer. The project will include 10 discreet inputs/outputs and 3 alarms as described in the table.
  2. Integrate the PLC program with an existing HMI project.
  3. Perform function testing and integration testing in person and/or remotely with De Dietrich personnel.
