Tricon system features
In order to ensure the integrity of the system at all times, Tricon has the following features to provide a triple module structure, with three identical sub-circuits each independently performing the degree of control. There is also a dedicated hardware/software structure for “tabulating” inputs and outputs
Withstand harsh industrial environments.
Can be installed on-site, can be on-site online module level installation and repair work without disrupting the field wiring. Can support up to 118 /0 modules (analog and digital) and optional communication blocks, communication modules to connect to Modbus master and slave stations, Or connect Foxboro to the Honeywell Distributed Control System (DCS), other TRicons in Peer-to-Peer networks, and external hosts on TCP/IP networks. It can support remote I/O modules located up to 12 km (7.5 mi) away from the main frame
Use Windows-based programming software to complete the development and debugging of control programs in the input and output modules with intelligent functions to reduce the workload of the main processor, each /0 module has three microprocessors. The input module’s microprocessor filters and repairs the input, and detects hardware faults on the module. The output module’s microprocessor provides information for voting on the output data, checks the validity of the output status by the feedback loop voltage at the output, and can diagnose problems with the field line
Provides comprehensive online diagnostics with repair capabilities.
Routine maintenance can be performed while Tricon is operating normally without interrupting the control process
Provides “hot spare” support for I/O modules, which can be used in some critical situations where service cannot be provided in a timely manner.
