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 <https://www.graco.com/us/en/in-plant-manufacturing/products/liquid-coating/meter-mix/plural-component-mixing-equipment/promix-pd.html>`_.

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 <https://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.
