Tricon is characterized by its high fault-tolerant programmable and process control technology.
Its features are as follows: A. Triple Modular Redundant Structure (TMR) is provided, which has three identical subcircuits, and each subcircuit performs independent degree of control. There is also a dedicated hardware/software architecture for “voting” input and output. Able to withstand harsh industrial environment. C. It can be installed in the field, or installed and repaired at the module level online in the field, without disturbing the field wiring. D. Support up to 118 I/O modules (analog and digital) and optional communication modules. Communication module can be connected to Modbus host and relying party, or Foxboro and Honeywell distributed control system (DCS), other Tricons in peer-to-peer network and external host on TCP/IP network. E. It can support the remote I/O module up to 12km from the mainframe. F. Use the programming software based on Windows NT system to develop and debug the control program. G. Intelligent functions of input and output modules to reduce the workload of the main processor. There are three microprocessors in each I/O module. The microprocessor of the module filters and repairs the input, and diagnoses the hardware faults on the module. The output microprocessor provides information for the voting of input data, checks the validity of the output state through the feedback loop voltage at the output end, and can diagnose the field line problems. H. Provide comprehensive online diagnosis with maintenance capability. I. Routine maintenance can be performed when Tricon is up and running without interrupting the control process. J. Provide “hot standby” support for I/O modules, which can be used in some critical situations where services cannot be provided in time.
