Introduction   In order to solve the problem of large workload, low efficiency and low accuracy of I&C wiring design.

    Method   The Siemens COMOS platform was used to develop intelligent wiring software. Through modeling local equipment, DCS equipment library and channel, the related interfaces were developed to achieve local equipment wiring, DCS wiring and cable merging automatically.

    Result   Finally reach a key to export finished products of wiring diagram.

    Conclusion   By popularizing and applying in actual engineering, it shows that intelligent wiring software can greatly reduce the workload, improve the wiring accuracy, shorten the construction period, and effectively save labor costs. In the future, the software will be further upgraded to achieve wiring design for the other majors such as electrical.
