PURPOSE:To simplify the setting action of a program controller by using a parameter which is under execution unless a special parameter is newly set when parameters are set for each section of a program pattern. CONSTITUTION:An inside device 2 can be freely loaded in and unloaded from a case 1 of a program controller, and display devices 31 and 32, etc. are provided at the front face of the device 2. A central processor performs the control operation according to the program pattern set device, etc. stored in a RAM, etc. and produces an output signal. Thus a set of specific PID constants is set at a certain section and at the same time the number of this set is registered. As a result, a parameter can be set for each section with designation of said set number. Then the operation of the next section is carried out after deciding by a program stored previously in a ROM that the parameter under execution (same as the parameter of the preceding section) is set unless a special parameter is newly set. |
