Abstract To against the problems in existing ESD system of hydrogen cracking plant in Mao Ming Petrochemicals，the retrofit with TRICON system is
implemented. The hardware configuration of TRICON system，logic programming，the man-machine interface，and the system commissioning are introduced
emphatically. The practical application shows that the TRICON system overcome various disadvantages in the old system and ensured safety production
of the plant.
