Aseptic Fill-Finish, Lyophilization, Cleanroom EMS & GMP Utilities Integration Guide

Connecting GMP Freeze Dryers (Lyophilizers), Aseptic Filling Isolators, Cleanroom Environmental Monitoring Systems (EMS / Particle Counters), and WFI / Veolia Sievers® M9 TOC Analyzers to GxPHistorian GxP Industrial Historian

1. Overview: Sterile Drug Product (DP) & Facility Compliance (EU GMP Annex 1)

Under EU GMP Annex 1 (2022 Revision) and FDA 21 CFR 211, sterile Drug Product (DP) manufacturing and GMP facility utilities require continuous monitoring, alarm/excursion Event Frame tracking, and electronic signatures across four critical infrastructure domains:

GMP Lyophilizers / Freeze Dryers (SP Scientific Hull / VirTis, IMA Edwards, Telstar, Martin Christ, Hof): Continuous tracking of shelf fluid temperature, product thermocouples, chamber vacuum pressure (Capacitance Manometer vs. Pirani gauge convergence), condenser temperature, and hydraulic stoppering pressure.
Aseptic Filling Lines & RABS/Isolator Barrier Systems (Bausch+Ströbel, Optima, IMA Life, Groninger, SKAN Isolators): Vaporized Hydrogen Peroxide ( $\text{VHP}$ / $\text{H}_2\text{O}_2$ ) decontamination concentration (ppm), isolator positive pressure cascades (Pa), unidirectional laminar airflow velocity (0.45 m/s ± 20%), and 100% In-Process Control (IPC) checkweigher fill weights.
Cleanroom Environmental Monitoring Systems (EMS) & Airborne Particle Counters (Particle Measuring Systems LasAir® III / Pro & Airnet® II, Lighthouse Solair, Beckman MET ONE, Siemens Desigo CC / Honeywell EBI / JCI Metasys): Continuous Grade A / ISO 5 and Grade B/C / ISO 7 differential pressure (Pa), temperature, relative humidity, and $0.5\,\mu\text{m}$ / $5.0\,\mu\text{m}$ non-viable particle counts via BACnet/IP and Modbus TCP.
Compendial Water Loops (WFI, PW, Pure Steam) & Analytical Transmitters (Veolia Sievers® M9 / M9e TOC & Mettler Toledo Thornton M800 Conductivity): Real-time USP <643> Total Organic Carbon (ppb) and USP <645> conductivity ( $\mu\text{S/cm}$ ), return loop temperature ( $> 80\,^\circ\text{C}$ sanitization), and ozone concentration.

Aseptic Fill-Finish, Lyophilization & EU Annex 1 GMP Utilities Visual Wiring Guide

1.5 Non-Technical Step-by-Step Physical & Software Connection Walkthrough

Sterile drug product (DP) suites and EU GMP Annex 1 utility rooms combine PLC-controlled machinery with PoE environmental sensors. Use this step-by-step physical connection table to wire each system to GxPHistorian:

Sterile DP / Utility System	Where to Plug In on the Physical Unit	Exact Touchscreen / Software Menu Path to Enable	Protocol & Test Command
1. GMP Freeze Dryers / Lyophilizers (SP Hull, `IMA Edwards`, Telstar, `Martin Christ`)	Walk into the technical service area (gray space) behind the cleanroom wall. Open the Lyo Main PLC Cabinet (`Siemens S7-1500` or `Allen-Bradley ControlLogix`). Plug a Cat6A cable into Northbound Port `X2` / `EN2T`.	In the Lyo SCADA (Telstar Lyogistics, IMA Sentinel, or Christ LPCplus), enable OPC UA Server (`Port 4840`) on the northbound interface. Ensure both Capacitance Manometer (`mTorr`) and Pirani Vacuum (`mTorr`) tags are exposed.	`nc -zv 10.20.90.10 4840`
2. Aseptic Filling Line (`Bausch+Ströbel`, `Optima`, `IMA`) + Barrier Isolator (SKAN, `Syntegon`)	Important: An isolator filling line has TWO separate PLCs—one for the SKAN Isolator (managing $\text{H}_2\text{O}_2$ VHP bio-decontamination, glove-port pressures, and laminar airflow) and one for the Vial/Syringe Filler (managing peristaltic/rotary pumps and 100% IPC checkweighers). Plug two Cat6A cables into the respective `X2` SCADA ports of both PLCs.	Enable OPC UA Server (`Port 4840`) on both the SKAN Isolator S7-1500 PLC (`10.20.90.11`) and the Bausch+Ströbel Filler PLC (`10.20.90.12`).	`nc -zv 10.20.90.11 4840` & `nc -zv 10.20.90.12 4840`
3. Non-Viable Airborne Particle Counters (PMS LasAir® III / Pro & Airnet® II, Beckman MET ONE)	Look at the underside of the stainless particle counter enclosure. Plug a Power-over-Ethernet (PoE `802.3af`) Cat6A cable into the sealed RJ45 Ethernet port (for `Airnet II` fixed sensors, this single cable provides both $24\text{V}$ power and Modbus TCP data!).	On the LasAir III touchscreen (or `Airnet II` web browser console), tap Setup $\rightarrow$ Communications $\rightarrow$ Network, set Static IP `10.20.90.21`, and toggle Modbus TCP = Enabled (`Port 502`, Unit ID `1`).	`nc -zv 10.20.90.21 502`
4. WFI Total Organic Carbon Analyzer (Veolia Sievers® M9 / M9e / 500 RL On-Line)	Open the hinged side splash cover on the rear/side I/O bay of the Sievers M9 analyzer. Plug a Cat6 cable into the RJ45 Ethernet port labeled `LAN`.	On the Sievers M9 touchscreen, tap Menu $\rightarrow$ Setup $\rightarrow$ Network & Comms $\rightarrow$ Modbus TCP. Set Static IP `10.20.90.30` and enable Modbus TCP Port `502` (Big-Endian `ABCD` Float32 registers for TOC `ppb`, Conductivity $\mu\text{S/cm}$ , and Temperature $^{\circ}\text{C}$ ).	`nc -zv 10.20.90.30 502`
5. Cleanroom Differential Pressure (`Pa`), Temp & `%RH` (`Siemens Desigo`, `JCI Metasys`, `Honeywell EBI`)	Connect `GxPHistorian` `edge-collector` to the Facility BMS / EMS VLAN (or install a LOYTEC / Contemporary Controls BASrouter BACnet MS/TP-to-BACnet/IP Router on the mechanical floor).	Register the `edge-collector` IP as a Foreign Device in your BMS BBMD (BACnet Broadcast Management Device) on `UDP Port 47808`. `bacnet_cov_worker.py` automatically maps ASHRAE `Status_Flags` to OPC Quality (`192/64/0`).	`python3 edge-collector/scripts/bacnet_cov_worker.py --self-test`

3. Domain-Specific Integration Configurations

3.1 Cleanroom EMS via BACnet/IP (`bacnet_cov_worker.py`)

Cleanroom differential pressure cascades (e.g., Grade B/C corridor at +30 Pa $\rightarrow$ Grade C Bioreactor Suite at +18.5 Pa $\rightarrow$ Airlock at +12.5 Pa), HVAC supply/exhaust airflows, and room temperature/humidity are managed by BACnet/IP controllers.

GxPHistorian GxP Historian includes a production-ready asynchronous BACnet/IP worker at edge-collector/scripts/bacnet_cov_worker.py (AsyncBacnetTelemetryWorker) and seeds Tag 301: CR_ISO7_DP_PV under BioCorp.Fremont.Facilities.Cleanroom_ISO7.

How IEEE/ASHRAE BACnet `Status_Flags` Map to GxP OPC Quality

In bacnet_cov_worker.py, status_flags_to_quality() reads both the presentValue and the 4-bit statusFlags array ([in_alarm, fault, overridden, out_of_service]) from each BACnet analog-input object:

fault = 1 $\rightarrow$ quality = 0 (Bad), status_code = 1: Sensor hardware failure; recorded in sensor_data for facilities maintenance but automatically excluded from mv_sensor_rollup_1m (WHERE quality >= 192).
out_of_service = 1 or overridden = 1 $\rightarrow$ quality = 64 (Uncertain), status_code = 3: Indicates a calibration technician placed the Magnehelic/differential pressure transmitter into manual override or out-of-service mode.
in_alarm = 1 $\rightarrow$ quality = 192 (Good), status_code = 4: Valid measurement currently breaching local BACnet alarm limits; included in all GMP calculations and triggers an ISA-88 Excursion Event Frame in PostgreSQL.

Configuring Additional Cleanroom Suites in edge-collector/scripts/bacnet_cov_worker.py:

worker = AsyncBacnetTelemetryWorker(
    ingest_url="http://localhost:8080/ingest",
    points=[
        BacnetPointSpec(tag_id=301, device_address="192.168.10.30:47808", object_identifier="analog-input,1", exc_dev=0.10, exc_max=10.0), # ISO-7 DP (Pa)
        BacnetPointSpec(tag_id=302, device_address="192.168.10.30:47808", object_identifier="analog-input,2", exc_dev=0.05, exc_max=30.0), # ISO-7 Temp (degC)
        BacnetPointSpec(tag_id=303, device_address="192.168.10.30:47808", object_identifier="analog-input,3", exc_dev=0.20, exc_max=30.0), # ISO-7 RH (%)
        BacnetPointSpec(tag_id=304, device_address="192.168.10.31:47808", object_identifier="analog-input,1", exc_dev=0.10, exc_max=5.0),  # Grade A Isolator DP (Pa)
    ],
)

3.2 Airborne Particle Counters (PMS LasAir® III / Airnet® II) & Veolia Sievers® M9 TOC via Modbus TCP

Both Particle Measuring Systems (PMS) LasAir® III / Airnet® II cleanroom particle counters and Veolia Sievers® M9 / M9e Total Organic Carbon (TOC) analyzers expose deterministic Modbus TCP register maps (port 502) that can be polled directly by Telegraf’s native [[inputs.modbus]] plugin in edge-collector/telegraf-clickhouse.conf:

# 1. Veolia Sievers M9 TOC & Conductivity Analyzer (WFI Loop Return)
[[inputs.modbus]]
  name_override = "sensor_data"
  controller = "tcp://10.20.60.15:502"
  slave_id = 1
  timeout = "3s"
  configuration_type = "register"

  holding_registers = [
    # USP <643> TOC (ppb) - IEEE 754 Float32 across 2 registers
    { name = "val", byte_order = "ABCD", data_type = "FLOAT32-IEEE", scale = 1.0, address = [300, 301] }
  ]
  [inputs.modbus.tags]
    tag_id = "601"

# 2. PMS Airnet II / LasAir III Grade A Isolator Particle Counter (0.5 um & 5.0 um counts/m3)
[[inputs.modbus]]
  name_override = "sensor_data"
  controller = "tcp://10.20.60.20:502"
  slave_id = 1
  timeout = "3s"
  configuration_type = "register"

  input_registers = [
    { name = "val", byte_order = "ABCD", data_type = "UINT32", scale = 1.0, address = [100, 101] }
  ]
  [inputs.modbus.tags]
    tag_id = "602"

3.3 GMP Lyophilizers (Freeze Dryers) & SKAN Aseptic Filling Isolators

In lyophilization cycles (freezing, primary drying sublimation, and secondary drying desorption) running 48–120 hours, two vacuum gauges are monitored simultaneously over OPC UA ([[inputs.opcua]]):

Capacitance Manometer (MKS Baratron®): Gas-composition independent absolute chamber pressure (mTorr or mbar, low_limit = 50 mTorr, high_limit = 150 mTorr during primary drying).
Pirani Thermal Conductivity Gauge: Reads higher in water vapor than nitrogen; when the Pirani pressure curve converges downward to meet the Capacitance Manometer curve ( $\Delta P_{\text{Pirani-CapMan}} \le 5\,\text{mTorr}$ ), sublimation is complete and the lyophilizer transitions from Primary Drying to Secondary Drying.
