There are six functional blocks in the DeltaV system:
***Advanced Control Function Block - Implement complex algorithm functions for * * * process control
Advanced Function Block - Performs advanced functions such as voting and sequencing
Analog Control Function Block - Executes simple and complex algorithms for analog control of * * *
Energy Metering Function Block - Performs mathematical flow calculations for natural gas, steam, or other fluids
Input/Output (I/O) function block - used for scaling, converting, and filtering input and output signals in other function blocks or field devices
Logical Function Block - Executes logical functions for sequence, planning, and interlocking.
Math function block - performs mathematical functions such as transformation, integration, and accumulation.
Timer/Counter function block - performs timer and counter functions for control and * * *.
1. CPU module
The CPU module mainly consists of a microprocessor (CPU chip) and memory. In a PLC control system, the factory CPU module is equivalent to a human brain. It continuously collects input signals, executes user programs, and refreshes the system's output; Memory is used to store programs and data.
2. Input output module
The input module and output module are abbreviated as I/O modules. They are the eyes, ears, hands, and feet of the system, serving as a bridge between external field devices and CPU modules.
