PURPOSE:To constitute a desired control loop, by realizing a change for the designation of a program from outside and thus realizing an easy correction and alteration of the program by an operator at the site. CONSTITUTION:Various arithmetic elements necessary for the decision of functions of an adjusting meter 1 are distributed on a keyboard 2 with use of the measurement words. Then a program to form a control loop of a desired function is produced by operating the keys. This program is written into a memory 3 by a program producing device 2. The meter 1 fetches a digitized input signal and reads the arithmetic elements which are previously stored. Then an operation is carried out by an arithmetic processor based on the program of the memory 3. |
