ROCKWELL T8403 Rockwell Batch Sequencer

ROCKWELL T8403 When configuring batches, engineers typically choose a control solution based on the size of the system. Conventional wisdom holds that low-volume systems require controller-based sequencing solutions, while larger systems require server-based solutions. Despite tradition, the size of a system is not the best indicator of a suitable solution, as a small application or a single unit may have complex requirements. For example, a unit may have hundreds of recipes, complicating batching and sequencing when using hard-coded or controller-based systems.

ROCKWELL T8403 To determine the correct solution, let’s consider three types of batch and sequencing solutions: hard-coded, controller-based, and server-based (commonly referred to as composite). Few systems take advantage of custom hard-coded configuration, as it only allows setpoints to be downloaded into a fixed sequence. As a result, the user is forced to change the code when the sequence must be changed. This adds risk to the process and can add substantial costs to retesting and validating the system. Due to the rigidity of hard-coded solutions, many engineers turned to controller-based solutions for their low-volume needs. This is suitable if the application requires sequence management functionality, but the complexity of the process may not warrant a server-based package.
