Element numbering

QElectroTech allows an automatic codification of elements. This feature is useful for the creation of reports, Bill of Materials (BOM), and for the identification of devices at the physical installation and schemas.

QElectroTech allows defining multiples auto numbering patterns. It also provides many flexibility on the creation of auto numbering pattern using text, variables and sequential numbers.

Code defined by IEC 81346 norm.

  • A: Two or more purposes or tasks.

  • B: Converting an input variable into a signal for further processing.

  • C: Storing of energy, information or material.

  • E: Providing radiant or thermal energy.

  • F: Direct protection from dangerous or unwanted conditions.

  • G: Initiating a flow of energy or material.

  • H: Producing a new kind of material or product.

  • K: Processing signals or information.
