Basic Controllers and High Level Process Interface Units (HLPIUs) were part of the original DCS offering from Honeywell under the TDC 2000 brand. A few years later they were joined by MultiFunction Controllers which added considerable functionality. Originally configured and operated with Basic Operator Stations (BOS) and later Enhanced Operator Stations (EOS). Although this is early 80's technology, Intelligent Plant have the skills in house to configure tags, controllers, graphics and sequences. We have interfaced Citact SCADA directly on the hiway as an HMI and to run advanced applications.
The second generation Distributed Control System from Honeywell was TDC 3000. Intelligent Plant employees were involved in the commissioning and configuration of the first TDC 3000 system deployed in Scotland, in 1989. We have extensive experience with Process Managers, PLC Gateways, Application Module programming and History Module set up.
Key to all control systems are communication links to Vendor Packages; Compressors, Turbines, Subsea Systems, Metering etc. We have configured and performed troubleshooting on many connections using the Modbus and OPC protocols.
DCS and SCADA systems can have multiple configuration files in different formats that are very difficult to visualise or verify. We have developed an application to import these diverse files and display them in an interactive and intuitive way. Data sets can also be created and exported to excel or csv. This could be used to create the initial database for an Alarm Rationalisation project, for example.
With our extensive experience commissioning systems we fundamentally understand of control room operations. Combined with our systems knowledge we have created Alarm Analyses of unrivalled detail and utility. A small demonstration is available on this website, but get in touch to see our full capabilities.
