  • Regulatory and procurement clarity: Suppliers and inspectors referencing the standard will expect diagrams to use current symbol definitions — updating diagrams can prevent procurement or compliance issues.
  • Future-proofing designs: New symbols for digital/networked elements reflect common modern architectures (e.g., fieldbus, OPC-UA), making schematics more representative of current installations.
