Drugs are essential for maintaining human life and health, while they have significant influence on the human body. This requires proper quality of drugs medicines. In order to produce drugs with proper quality, appropriate production processes are necessary in addition to use of proper raw materials and their blending percentage. Drugs have been produced manually in the past. Recently, however, they are produced by production facilities that are automatically controlled by CS in order to enhance production efficiency. Therefore, proper workability and operability of CS has become more important. On the other hand, there exist issues that poor quality drugs are produced due to the malfunction of CS. For this reason, the regulatory authorities required drug production companies to prove that their drug production processes and CS that controls such processes are adequate to produce high-quality drugs by showing evidence based on documents or electronic data regarding drug development and verification. The procedure that proves the adequacy of the production processes is referred to as Process Validation (PV), while the procedure that proves the adequacy of the CS used for production is referred to as Computerized System Validation (CSV). Usually, PV and CSV procedures are implemented in a parallel manner along development when production facilities are built.\u00a0<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-2739021 elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"2739021\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-no\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-d57a28d\" data-id=\"d57a28d\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-5a0e645 elementor-widget elementor-widget-image\" data-id=\"5a0e645\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"1024\" height=\"572\" src=\"https:\/\/reliable.world\/wp-content\/uploads\/2022\/03\/PLV-validation-1024x572.jpg\" class=\"attachment-large size-large wp-image-1128\" alt=\"PLV-validation\" srcset=\"https:\/\/reliable.world\/wp-content\/uploads\/2022\/03\/PLV-validation-1024x572.jpg 1024w, https:\/\/reliable.world\/wp-content\/uploads\/2022\/03\/PLV-validation-300x168.jpg 300w, https:\/\/reliable.world\/wp-content\/uploads\/2022\/03\/PLV-validation-768x429.jpg 768w, https:\/\/reliable.world\/wp-content\/uploads\/2022\/03\/PLV-validation.jpg 1392w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-e2a0a86\" data-id=\"e2a0a86\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-a07ca4b elementor-widget elementor-widget-text-editor\" data-id=\"a07ca4b\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>At first, the CSV standards are stipulated according to each country that produces and sells drugs. Therefore, export of drugs on which CSV is conducted in accordance with the export country requirements must also be conducted again to meet the CSV standards of the importing country. Since a lot of labor is needed to conduct CSV, this has actually produce significant work load on drug production companies. Therefore, the International Society for Pharmaceutical Engineering proposed CSV standards that incorporate the CSV standards of each country. These standards are referred to as the Good Automated Manufacturing Practice (GAMP). Implementation of CSV in accordance with GAMP makes it comparatively easier to export drugs to other countries.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-e6344ce elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"e6344ce\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-no\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-4ab6122\" data-id=\"4ab6122\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-aefbfa9 elementor-widget elementor-widget-text-editor\" data-id=\"aefbfa9\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Therefore, GAMP has become the de facto CSV standard. Currently, the fifth edition of GAMP is being used. As mentioned earlier, the production processes of drugs have become complicated, and the functions of PBCS to correspond to this situation have also become complicated. In order to achieve complicated functions, PBCS has been developed by combining the following software programs: Packaged software that cannot be modified, configurable software, and individually-developed software. However, GAMP did not include any descriptions regarding CSV for CS with such complicated structures. Therefore, this has made it difficult for drug manufacturers to conduct CSV. Manufacturing equipment will be used for a longer period of time once it has been developed and built. During the period of operation, various processes, facilities, and PBCS are modified. With respect to CSV, when modification is done, the functions and performance of the modified part needs to be confirmed immediately, and their adequacy also needs to be proved. Additionally, the modified functions might have influence on other functions. However, it has become difficult to understand the accurate range of this influence. These facts have caused various problems to drug manufacturers regarding the implementation of CSV for PBCS.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-bd95b20 elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"bd95b20\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-no\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-1e97898\" data-id=\"1e97898\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-6ad7141 elementor-widget elementor-widget-heading\" data-id=\"6ad7141\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Outline Of PLC Based Computerized System And Validation Procedure<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-01649b5 elementor-widget elementor-widget-text-editor\" data-id=\"01649b5\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>PLC is a computer that can develop programs that are equivalent to relay circuits which control processes.

To leverage the benefits of productivity enhancement tools available in the latest process control packages, a clear and complete software functional requirement specification document must be developed before configuring any process control system. Read on to know more\u2026<\/p><p>In the real business world, it has often been seen that validation professionals from pharmaceutical companies lack practical experience in relation to the development and use of Programmable Logic Controller (PLC) application software. Understanding and configuring today\u2019s software packages are easier than ever before; however validation of automation systems is indeed an arduous task.<\/p><p>Typically, control system integrators or system suppliers are not trained in current good manufacturing practices (cGMP) or good X practices (GxP) relating to Food and Drug Administration (FDA) compliance where \u2018x\u2019 can mean clinical, laboratory, manufacturing, pharmaceutical and others. They also do not possess the solid validation operational experience required for FDA compliance. The know-how gap between supplier and users in the pharmaceutical industry is obvious, and problems caused by this gap can be numerous. As a result, good automation manufacturing practice (GAMP) has come into being to address these issues as it considers the overall automation system validation methodology. Yet, even GAMP serves to provide a guideline only rather than dealing with practical development of the PLC cycle.<\/p><p>Therefore, the emphasis is on good engineering practice (GEP) which ensures that engineering or software development methodology generates deliverables that support the requirement for qualification or validation in the pharmaceutical industry. The control system integrator or system supplier must plan a software development strategy that holds the key to a successful compliant system.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-de3695c elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"de3695c\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-0cf5030\" data-id=\"0cf5030\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-54c43d1 elementor-section-full_width elementor-reverse-tablet elementor-section-height-default elementor-section-height-default\" data-id=\"54c43d1\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-no\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-037862c\" data-id=\"037862c\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-4c61ab9 elementor-widget elementor-widget-heading\" data-id=\"4c61ab9\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Good Manufacturing Practices (GMP) in Process Plants<\/h3>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3b96cff elementor-widget elementor-widget-text-editor\" data-id=\"3b96cff\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>Today\u2019s control software packages use a variety of programming languages such as function blocks, ladder logic, sequential function charts, etc. These programs must be clearly documented and easy to update in order to improve the plant\u2019s productivity over its expected life.

When a pharmaceutical manufacturer realises that validation of either an existing or new computer system is required, and enters into a contract with a supplier, it&#8217;s important that a working relationship is established. This has to be more than a mere purchase order supply agreement, and has to account for the needs and responsibilities of both parties.<\/p><p>Validation is the documented evidence that a process or system does what it&#8217;s supposed to do. In the pharmaceutical industry, this means that a process must manufacture the final product within established limits and specifications and that each step of the process be recorded. A computer system which controls the process must operate in a manner that will maintain these product specifications.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-9f89b29 elementor-section-full_width elementor-section-height-default elementor-section-height-default\" data-id=\"9f89b29\" data-element_type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-b7bc764\" data-id=\"b7bc764\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-inner-column elementor-element elementor-element-ba926d5\" data-id=\"ba926d5\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap\">\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>PLC Validation Computerized System Validation for PLC Based System Recently, Computerized Systems (CS) using Programmable Logic Controllers (PLC) have been utilized for controlling drug manufacturing equipment (hereafter, manufacturing equipment).
