A simplex sequence controller for transmittal of output data is disclosed and includes a time base generator for generating a timing signal, a memory device having a plurality of addressable sequential storage locations for storing a sequence of data pattern with a plurality of output lines and a plurality of input address lines connected to the storage locations, along with an addressing apparatus connected to the memory device input address lines for directing access to predetermined storage locations at predetermined points in the data sequence, and address reset apparatus providing feedback from a first predetermined one of the output lines of the memory device to the addressing apparatus to direct access to a predetermined initial data sequence for output from the memory.
A sequence controller includes a sequencer to which a basic clock is applied. The sequencer sequentially generates at a period of 125 .mu.sec address signals for reading statements to be executed at a period of 125 .mu.sec and one block of statements to be executed at a period of 10 msec or one block of statements to be executed at a period of 100 msec. A memory stores the above statements beforehand. The statements are selectively read out of the memory in accordance with the address signals and fed to a decoder. The decoder decodes the statements and generates control signals respectively corresponding to the statements and feeds the control signals to a switch. The switch controls each of a plurality of function registers on the basis of the respective control signal.
