3301 TRICONEX Controller Card Each TMR digital input module has three separate sets of electronics, called channels, that independently process the module’s field data. Each channel places the processed data in an array and transfers that array to the MP associated with that channel upon request. MPs votes on the data before passing it to the application. The DI module includes complete, continuous diagnostics for each channel. If the diagnostic detects a fault on any channel, the fault indicator lights up and activates the system alert. The fault indicator identifies the channel fault, not the entire module fault. The D module continuously validates the system’s ability to detect transitions to the opposite state. The D| module is guaranteed to function in the event of a single failure and to continue to function in the event of multiple failures. The D module supports the hot standby module. Each DI module is mechanically locked to prevent improper installation in the configured substrate. The Model 3301 D| module is available on the following substrates: Model 2301 for curved applications. D1 External terminal substrate for solid-state input external terminal panels in Gauller applications, or Type 9573-610 DI hazardous site external terminal panels
Key features of the Tricon control system
Tricon is a highly fault-tolerant programmable and process control technology
Its characteristics are as follows:
A, provides a three-mode multi-remainder structure (TMR) with three identical subcircuits, each performing an independent degree of control. There is also a dedicated hardware/software architecture for “voting” on inputs and outputs
Able to endure harsh industrial environments.
C. It can be installed in the field and module level D can be installed and repaired online in the field without interfering with the field wiring. Up to 118 I/O modules (analog and digital) and optional communication modules are supported. Communication modules can be connected to Modbus hosts and slave devices, or to Foxboro and Honeywel Distributed control Systems (DCS), other Tricons in peer-to-peer networks, and external hosts in TCP/IP networks.
E. Can support remote I/O modules up to 12 km from the mainframe.
F. Develop and debug control programs using programming software based on Windows NT systems. G. Intelligent functions in the input and output modules reduce the workload of the main processor. Each /0 module has three microprocessors. The input module’s microprocessor filters and repairs the input and diagnoses hardware failures on the module, the output module’s microprocessor provides information for voting on the output data, checks the validity of the output state by the feedback loop voltage at the output, and can diagnose field line problems.
H. Provide comprehensive online diagnostic and repair capabilities.
When Tricon is up and running, routine maintenance can be performed without interrupting the control process.
J. Provide “hot backup” support for I/O modules, which can be used in certain emergency situations where service cannot be provided in time.
