3.System Features and Functions
High fault tolerance:Provides a three-module redundant structure(TMR)with three identical sub-circuits,each of which performs a certain degree of independent control and can withstand harsh industrial environments.
Field installable:The module level can be installed and repaired online in the field without affecting the field wiring.
Module scalability:Supports up to 118 I/O modules(analog and digital)and optional communication modules.
Remote communication capability:Communication modules can be connected to Modbus hosts and slaves,or to Foxboro and Honeywell distributed control systems(DCS),other Tricons in peer-to-peer networks,and external hosts in TCP/IP networks.
Support for remote I/O:Supports remote I/O modules up to 12 kilometers away from the host.
Windows NT-based programming:Develop and debug control programs using Windows NT-based programming software.
Intelligent functions:Intelligent functions in the input and output modules reduce the workload of the main processor.Each input/output module has three microprocessors.
Comprehensive online diagnostics:Routine maintenance can be performed when Tricon is operating normally without interrupting the control process.
Hot standby support:Provide”hot standby”support for I/O modules,which can be used in emergency situations where services cannot be provided in time.
