Zusammenfassung:	The utility model discloses a control system for bell type annealing furnace process. The control system comprises a central processing unit (CPU), a frequency converter unit, a coil base control unit and a heating bell control unit. A CPU control unit is connected with the frequency converter unit through a PROFIBUSDP cable, the heating bell control unit is connected with a quick coupling socket through the PROFIBUSDP cable, and the PROFIBUSDP cable of the short-circuited frequency converter unit and the PROFIBUSDP cable of the coil base control unit are connected with the quick coupling socket. The coil base control unit and a DP plug of the heating bell control unit are provided with terminal resistors respectively. The control system guarantees stability of a PROFIBUSDP network composed of all units and guarantees safety of the bell type annealing furnace process and continuity of the process.
