PURPOSE:To improve the operability of the controller greatly by setting a specific parameter in a CPU previously, decoding the contents of the parameter when an output request is received and reading data, and bringing output time under the control of a timer according to the data. CONSTITUTION:The parameter 1a' consisting of the address of previously stored data, data output time, and the frequency of data output is set in the CPU1. A parameter decoding part 8 once receiving a data output request signal 1a and the parameter 1a' from the CPU1 decodes and sends the contents of the parameter 1a' to a data readout part 7 and also sends a request to read data. The readout part 7 initiates an interruption to the CPU1 and reads and stores data of a specified address in a data storage part 4. An input/ouput control part 5 having received information on that from the storage part 4 fetches the data from the storage part 4 and passses it to a process output device 6 while the data output time is controlled by the timer part 9. The device 6 outputs data for a time T1 and is held reset for a time T2. |
