Overview¶
The PD3K Rockwell Software Development Kit (SDK) is a collection of sample code for easily controlling a PD3K proportioner through a Rockwell 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 PD3K product, which is designed to support 3-component mixes. SDKs for the other ProMix PD products can be found at help.graco.com.
Compatibility¶
The examples in this SDK are built using Rockwell Studio 5000 Logix Designer® v32.04. The GracoPD3K_Example.ACD project is built for a 5069-L306ER CompactLogix™ Controller using firmware v32. If using a different controller, the model may be changed using Logix software.
All code is compatible with CompactLogix™ and ControlLogix™ controllers firmware v32 and later. Backwards compatibility with earlier firmware versions may be possible, but is not tested and not guaranteed.
All code is written in Ladder language. The main reason for this is portability - Rockwell’s licensing structure supports Ladder at the base level, but requires an upgraded license to work with other PLC languages. Writing all code in Ladder lets any PLC programmer view the code and modify it if needed, regardless of which license they use.
