# Overview

The PD2K Dual Panel Siemens Software Development Kit (SDK) is a collection of sample code for easily controlling a PD2K proportioner through a Siemens PLC. The code is designed to simplify many common integration challenges, allowing you to build a working system very quickly.

## About the PD Platform

The ProMix PD Platform is a family of electric dosing pump systems utilizing positive displacement (PD) technology. More information can be found on the Graco product page.

This SDK is specifically designed for the ProMix PD2K Dual Panel Proportioner for Automatic Spray Applications, which includes two independent 2-component mix units controlled from a Communication Gateway Module (CGM). SDKs for the other ProMix PD products can be found at help.graco.com.

## Compatibility

The examples in this SDK are built using the Siemens TIA Portal platform V17 Update 4 with STEP 7 Professional. Examples for earlier versions are not provided at this time.

All code is compatible with the latest hardware/firmware products for the S7-1200 and S7-1500 families of CPUs. The example project is built specifically for CPU 1211C DC/DC/Rly (article number 6ES7 211-1HE40-0XB0). backwards compatibility with obsolete/end-of-life products in the S7-1200/1500 family may be possible but is not guaranteed.

All code is written in either SCL or LAD language.
