Collaborative Information Server review
A distributed SCADA and information system with ISA-18.2 alarms and HTML5 access.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
Collaborative Information Server (CI Server) is Yokogawa’s supervisory control and information system for industrial plants, bringing control-system, sensor, equipment and business-system data into centralized operation and monitoring. It is aimed at mid-market and enterprise organizations managing plant operations across sites, particularly teams that need alarm management, historical process data and remote operator access. Browser-based HTML5 clients cover remote operation, while PC, tablet and smartphone access supports operators beyond a control-room desktop.
Its strongest fit is in environments where alarm discipline, data retention and distributed administration matter together. The built-in alarm module is compliant with ISA-18.2, and the system includes long-term process and operational data storage, reporting, audit trails and operator history. Centralized and enterprise engineering across distributed servers, plus redundant server configurations, address larger operational architectures. Interfaces span OPC UA and OPC Classic, ODBC, MQTT, IEC 60870-5, IEC 61850, DNP3, Modbus, HART, Vnet/IP and vendor systems including Rockwell Automation, Siemens and Emerson. Yokogawa documents both on-premises and Yokogawa Cloud deployment, with a RESTful API for system integration.
The product’s scope comes with a procurement trade-off: Yokogawa requires a sales quotation and does not publish plan tiers, so buyers cannot compare public tier prices before engaging sales. Documentation is the listed support channel. CI Server is a better match for teams that need its broad industrial interfaces, alarm functions and redundant, distributed design than for smaller operations seeking a narrowly scoped or readily priced SCADA package. Buyers should also assess how its architecture and deployment options fit their operating model before selecting it.
