  A state in which accelerator system works at a given moment of time is determined by the state machine. The idea of the project has been based on FSM - finite state machine, in which each of the states is precisely determined by assigned specified operations on subsystem devices of the accelerator system such as e.g. magnets of storage rings, RF transmitters etc. To ensure high reliability, the main part of the project has been based on PLC - Programmable Logic Controller. StateMachine wich is a TangoClass has been written in Python using the facadedevice library, that allows information from the control system to be delivered to the PLC system. By using an universal Tango Class AllenBradleyEIP the state machine shering an informationa about accelerator system to the Tango control system. This information is archived in Cassandra database system by using the Tango HDB++ archiving system.
