Automation Systems Lifecycle Upgrade
Upgrading eight GMP drug substance manufacturing systems from end-of-life automation platforms to fully OEM-supported hardware in a regulated biomanufacturing environment.
The upgrade scope included legacy Allen-Bradley PanelView HMI equipment, controller hardware, industrial Ethernet infrastructure, and the supporting validation documentation required for GMP release.
Overview
Eight GMP automation systems within a drug substance manufacturing facility had reached end-of-life across three hardware layers: controllers, HMIs, and network switches. OEM support had been discontinued, replacement parts were no longer manufactured, and the systems required re-qualification under the site’s CSV framework.
Mangan Biopharm supported a structured lifecycle upgrade program, migrating all eight systems from Allen-Bradley SLC 500 controllers and PanelView Plus 6 HMIs to CompactLogix 5380 and PanelView Plus 7 hardware, while replacing Cisco IE-3000 network switches with IE-3300 infrastructure. Full IQ/OQ/PQ qualification was completed for each system.

System Scope
| System | GMP Function |
|---|---|
| Autoclave | Sterilization of product-contact equipment and materials |
| Purified Water Production (RO) | Process water generation for product-contact utility use |
| Glassware Washer | Cleaning cycle control for product-contact glassware |
| COP Clean-out-of-Place System | Automated clean-out-of-place sequencing for process equipment |
| Clean Steam Generator | Clean steam generation for product-contact utility use |
| Robotic Bottle Storage and Retrieval | Automated storage and retrieval for materials management |
| WAVE25 Bioreactor #1 and #2 | Single-use bioreactor process control for direct drug substance production |
Delivery Approach
The upgrade was structured across seven phases under the client’s Automation Project Delivery SOP, with documentation review and approval required at each phase gate.
| Phase | Scope |
|---|---|
| Basis of Design | Defined hardware selections, procurement strategy, validation approach, and implementation scope for all eight systems |
| Detailed Design | Reviewed baseline documentation and incorporated redlines for URS, FS, HDS, and SDS updates |
| Implementation | Converted SLC 500 ladder logic, verified functional equivalence, fabricated replacement panels, and supported FAT |
| Testing | Confirmed installation and network integration through site acceptance testing |
| Commissioning / Verification | Executed IQ, OQ, and PQ per system; remapped PI tags; verified audit trail function |
| Training | Supported operations and maintenance transition to CompactLogix and PanelView Plus 7 |
| Close-out | Completed final documentation package, punch list resolution, and project turnover |
Hardware Migration
| # | Legacy Component (EOL) | Replacement |
|---|---|---|
| 1 | 1747-L552 SLC 500 + 1746 I/O Modules | 5069-L330ER CompactLogix + 5069 I/O Modules |
| 2 | 2711P-B6M20A8 PanelView Plus 6 | 2711P-T10C22A9P PanelView Plus 7 Performance |
| 3 | Cisco IE-3000 Industrial Ethernet Switch | Cisco IE-3300 Industrial Ethernet Switch |
| 4 | Legacy Control Panel | New Control Panel built to current standards |
Verified Results
Parts Availability Restored
All EOL hardware was replaced with current-production equivalents and active OEM support was confirmed.
Production Continuity Maintained
Cutovers were executed within scheduled maintenance windows with no unplanned production downtime.
Validation Documentation Current
Updated documentation and complete IQ/OQ/PQ packages were produced and approved for each system.
PI Historian Continuity Confirmed
Dozens of PI tags were remapped and verified against the CompactLogix tag database.
Audit Trail Integrity Maintained
21 CFR Part 11 audit trail functionality was verified as part of OQ execution.
Network Infrastructure Current
IE-3000 switches were replaced with IE-3300 hardware while preserving topology, VLAN segmentation, and IP addressing.
GMP Automation Lifecycle Upgrade Considerations
Plan Before the Window Closes
Secondary market availability for discontinued automation hardware depletes unevenly. Early project initiation creates a materially different risk profile than emergency replacement under production pressure.
Treat Program Conversion as Verification
SLC 500 to CompactLogix conversion should be reviewed against the original Functional Specification, not treated as a direct translation exercise.
Scope PI Tag Remapping Early
Historian tag remapping and report verification can compress commissioning schedules if the site’s historian team is not engaged during detailed design.
Documentation Updates Are Fixed Cost
Controller replacement without current URS, FS, SDS, and HDS documentation creates an undocumented change, regardless of implementation quality.
Mangan Biopharm has executed automation lifecycle programs in regulated biomanufacturing environments for more than 25 years. Platform continuity, site familiarity, and experience navigating technical execution alongside CSV requirements helped the program remain a managed capital project instead of an operational disruption.
