Product Description: TRICON 3704E isolated analog input modern programmable logic and process controller
1.1 What is TRICON?
TRICON is a modern programmable logic and process controller that can provide a high system fault tolerance controller 3 below explain how the two things are side-by-side suffering from TRICON system master
Want features.
1.1.1 What is Fault Tolerance?
Fault tolerance is the most important capability of the TRICON system, which refers to the ability to detect transient and steady-state error situations and take appropriate online actions. Have fault tolerance
The security of the controller and the process it controls is enhanced, and the utilization rate is improved.
TRICON gives its fault tolerance through the three = recombination redundant structure (TMR). The system consists of three identical system branches (except for the power module, which is doubly redundant). Each department
The main branch executes the control program independently and works in parallel with the other two branches. The hardware voting mechanism checks and validates all digital inputs and outputs from the field. Analog inputs are subjected to
Median selection process.
Because each branch is isolated from the other two, any single point failure in the Any-branch is not transmitted to the other two branches. If a hardware failure occurs on one side, the failed side can
Is compensated by the other two. As a result, repair work, including removal and replacement of failed modules in failed branches, can be carried out while TRICON is online without interrupting the process. The system reconfigures itself
Put in place adequate TMR operation.
Extensive diagnostic work for each branch, each module and each functional circuit can detect faults in operation in time and report them with indicators or alarms. Diagnostics can also put information about the fault
Stored in system variables. When a fault is found, the operator can use the diagnostic information to modify the control action or to guide its maintenance process.
From the user's point of view, use is simple because this triple system works like a single control system. The user connects sensors and actuators to a single - terminal and applies logic with a - group
Programming TRICON. The rest is being handled by TRICON itself.
