Application Scenarios

Pharmaceutical Batch Control: In GMP-regulated pharmaceutical manufacturing, the CI853 license enables 800xA systems to communicate with laboratory balances, pH meters, and conductivity analyzers via RS232. Dual ports support simultaneous connections to reactor temperature controllers and inline particle counters, ensuring complete batch documentation and 21 CFR Part 11 compliance. The perpetual license model aligns with pharmaceutical industry's preference for validated, unchanging automation infrastructure.

Petrochemical Analyzer Integration: Refineries and chemical plants rely on gas chromatographs, mass spectrometers, and NIR analyzers that communicate exclusively via RS232. The CI853 license allows 800xA DCS to acquire real-time composition data from these instruments, enabling advanced process control strategies like inferential property control and blend optimization. Redundant serial connections to critical analyzers ensure continuous data availability during instrument maintenance.

Water & Wastewater SCADA: Municipal water treatment facilities use the CI853 license to connect 800xA SCADA systems with legacy chlorine analyzers, turbidity meters, and flow totalizers installed decades ago. The dual RS232 capability supports communication with both primary and backup instruments, meeting regulatory requirements for redundant monitoring in drinking water applications.

Manufacturing Execution Systems: Food and beverage producers integrate barcode scanners, label printers, and checkweighers into 800xA-based MES platforms using CI853-enabled serial communication. Real-time weight data from filling lines and lot tracking information from scanners flow directly into batch records, eliminating manual data entry and reducing compliance risks.

Power Generation Monitoring: Utility-scale power plants employ the CI853 license to interface 800xA control systems with emissions monitoring equipment, vibration analyzers, and legacy turbine controllers. Serial communication provides deterministic, low-latency data transfer for critical protection functions where Ethernet-based protocols introduce unacceptable delays.

Technical Parameters & Selection Guide

Selection Criteria: Choose the CI853 license when your 800xA system requires serial communication with devices lacking Ethernet, PROFIBUS, or Modbus connectivity. Verify that your controller runs 800xA version 6.0 or later—earlier versions require system upgrades before license activation. Confirm that the CI853K01 hardware module is installed in your controller rack; the license cannot function without the corresponding physical interface card. For applications requiring more than two serial devices, consider multiple CI853K01 modules with corresponding licenses, or evaluate ABB's CI854 Ethernet-to-serial gateway for centralized serial device management.

Extended Functions

Custom Protocol Development: Beyond standard RS232 communication, the CI853 license supports custom protocol implementation using 800xA's structured text programming. Develop proprietary message parsers for non-standard instruments, implement checksums and error correction algorithms, or create protocol converters that translate between different serial device languages.

Data Logging & Buffering: Configure the 800xA controller to buffer serial data during network outages, ensuring no analyzer readings are lost during IT infrastructure maintenance. Implement time-stamped data queues that automatically synchronize with historians when connectivity is restored.

Multi-Drop Serial Networks: While each CI853 port supports point-to-point connections by default, the license enables multi-drop RS485 configurations when used with appropriate signal converters. Connect up to 32 devices on a single serial bus, ideal for distributed sensor networks in large process units.

Remote Diagnostics: Leverage 800xA's remote connectivity features to troubleshoot serial communication issues from engineering workstations anywhere in the plant network. View real-time serial traffic, adjust communication parameters, and reset ports without physical access to the controller cabinet.
