Calibrating one device isn't so hard. Doing a few hundred or a few thousand is tougher. But calibrating all of them in a large pharmaceutical plant governed by the U.S. Food and Drug Administration's CFR 21 Part 11 regulations is a whole different ballgame of required validations and certifications.

To give their pharmaceutical end users some much-needed assistance, Emerson Process Management and Beamex recently developed an innovative method for linking Emerson's Asset Management Suite (AMS) Device Manager (DM) software with Beamex's MC5 portable calibrators and CMX software. This technical partnership allows calibration data to be collected by AMS DM; transferred to MC5 and CMX for analysis, verification and sign off; and then sent back to AMS for documentation and certification. This streamlined process can save users hundreds of hours compared to traditional calibration and validation procedures. This data transfer also is aided by Beamex's CMX Connection software.

"Emerson recognized that our existing Device Manager tools and strategies might not be enough for users in the more regulated process industries," said Richard Barnes, Emerson's plant asset management and asset optimization consultant. "So we integrated AMS DM and CMX so they can exchange information with help from CMX Connection and greatly reduce calibration times."

For example, GlaxoSmithKline's (GSK) plant in Cork, Ireland, has replaced its legacy, mostly manual calibration method with the combined AMS DM and CMX solution. The new system has been up and running at GSK Cork for about one year.

"We used to have a mostly paper-based calibration process. Forms were filled in by the technicians, and then data was entered manually by the administrators. It was very static system," said Don Brady, GSK Cork automation engineer. "So in the first quarter of 2009, we launched our Primary Supply Agile Engineering team, and they confirmed our calibration cost problem and assigned us to identify ways to reduce these expenses."

Brady and Barnes presented "Calibraton Excellence" and a separate live demonstration of the new AMS DM and CMX tool this week at the Emerson Global Users Exchange in Nashville.

Subsequently, GSK's calibration improvement project focused on three areas:

  • Instrument diagnostics—including shifting calibrations of non-critical instruments from "on schedule" to "on demand," and relying on smarter diagnostics from instruments;
  • Paperless calibration—to help shorten calibration time and eliminate non-calibration support functions, such as document management, manual approvals and correction of transcription errors;
  • Calibration analysis—to examine historical data and help recommend interval extensions between calibrations, so long as existing data shows that previous calibrations met stringent corporate policy. 

"We're trying to achieve calibration efficiencies by using condition monitoring to reduce our total number of calibrations and then performing the remaining calibrations in a timely and efficient manner," explained Brady. "This means synchronizing instrument data between the calibration management system and the asset management system; using documenting calibrators; optimizing scheduling of planned periodic calibrations; and removing paper from the calibration process."

Beady added that GSK Cork is a highly automated manufacturing facility and serves as the primary production site for several of GSK's best-selling products. The plant employs more than 300 people and contains about 4,000 instruments, including mostly HART and Foundation fieldbus devices, installed over the last 12 years. The vast majority of these instruments are connected to one of the plant's six DeltaV systems, which employ a combination of rack I/O, remote I/O and Foundation fieldbus I/O systems.

"Besides being required to have CFR 21 Part 11-compliant signatures for data entry and approvals, we also had to monitor 1,100 smart-instrument diagnostics, develop an audit trail for 1,100 changes to that smart instrumentation and electronically document our smart-instrument configurations," added Brady. "We also had full participation from staff, who did training and learned how beneficial the new calibration system was going to be. Our craft supervisors and technicians were included in the project from day one, so there were no operational surprises by the time we reached the go-live date."

Brady reported that GSK's calibration improvement project, including using the combined AMS DM and CMX, helped the facility:

  • Reduce the steps in its overall calibration process from 17 steps to 10 steps;
  • Remove two steps that each posed risks of human data-entry errors;
  • Conduct Emerson and Beamex consulting workshops to review existing processes and optimize and refine the new processes to use improved technologies;
  • Use the new system's flexibility to manage workflow processes.

"We've also eliminated 21,000 sheets of paper per year," added Brady. "And we streamlined our end-to-end workflow, which reduced our calibration time by about 15 minutes per calibration. We've also eliminated calculation errors and rework because pass/fail calculations are performed in real-time out in the plant. In addition, we reduced scheduled calibrations by 8%, which was part of the data migration from a legacy system. We're also generating email alerts when a calibration failure happens, but now only calibration failures need to be reviewed and approved. Finally, we've been able to extend some intervals between calibrations, which are recommended by the devices and system in the form of email alerts. So far, we removed 234 calibrations from our schedule during first 12 months of analysis, and this should peak during the third year of operation."
