Case Study: FactoryTalk Batch Integration into a Control System for a Pharmaceutical Company
A large pharmaceutical company was commissioning and testing a new control system that was limited to providing only manual control of Equipment Modules. In some cases, manual control of Phases was available, with these Phases operating as coordination Equipment Modules but not having the infrastructure capable of interacting with a standard sequencing engine. To run a Batch Process the operators were required to manually enter recipe values and capture report information via an HMI, while tracking all activities in the various units. This allowed significant opportunities for operator errors (errors in setting parameters, errors in running the Equipment Modules in the correct sequence, or, in some cases, the physical inability to run multiple Equipment Modules at the same time).
ECS Solutions recommended and subsequently undertook the addition of a sequencing engine that not only stores the recipes (which contained the order in which the phases should be executed) but also stores all pertinent Parameter Values. With this modification, the operator is required simply to select a recipe together with all the equipment needed to run the batch. The batch engine is responsible for coordinating all the activities, including the parameter value transfer and Report information capture. The system also has the capability to prompt the operator regarding those tasks that require operator interaction. The installation of the addition did not interfere with any existing activities and all the existent code and functionality was preserved, with no changes being required.
