Introduction
Analysis of the core content of the standard
| Revision dimensions | 2000 version | 2018 version | Technological evolution |
|---|---|---|---|
| Control system | Electric unit combination instrument | DCS control loop | Intelligent upgrade |
| Graphic symbols | 78 basic symbols | 12 new special scenario symbols | Refined expression |

Key graphic symbol system
4.1 Specifications for primary source components
The measurement point symbol @ is uniformly applicable to various source points such as pressure/temperature/flow, and the line width cardinality is clearly defined as:
- Process pipeline outline: cardinality 1
- Instrument outer outline: cardinality × 2
- Key marking line: cardinality × 4
Key points for the implementation of DCS control loops
Typical temperature control loop 110-TIC-10101:
- Detection element: 110-TE-10101
- Safety barrier isolation: 110-TIB-10101
- Signal conversion: 110-TT-10101
- DCS regulator: 110-TIC-10101
Suggestions for the connection between the old and new standards
- Drawing conversion: Prioritize updating the control scheme diagram involving DCS loops
- Symbol replacement: Focus on replacing symbols for new equipment such as solenoid valves and permanent magnet couplers
- Training points: Special training is required on the new code system for on-site instrument boxes (such as IAJB intrinsically safe junction boxes)
