Integration of Package Units

Overview:

One of the current problems of batch automation specialists, especially in the pharmaceutical industry, is the integration of PLC-controlled units (package units, e.g. centrifuges, dryers) into DCS-like control systems maintaining homogenous structure. On the basis of IEC 61512-1:1997 standard Workgroup 2 of Hungarian Batch Forum prepared a draft Proposal for users and manufacturers of package units that suggests different methods for the integration of package units. The paper discusses the integration from a system-architecture point of view while the communication problems of control equipment are not considered.
