PURPOSE:To ensure a free change for an operand section of the control part of a sequencer, by providing an operand setting part to a sequencer system. CONSTITUTION:A CPU1 reads an operand via an operand setting part 3 and then a sequence program which is previously changed to the machine words via a program loader 4. The CPU1 links this sequence program to the operand and produces an object corresponding to each part of a control information part 8 for the sequence program to load the object into a memory 9 for sequence program. Thereafter, a logic part R starts and the information of a device to be controlled is supplied to the part 8 from a digital input device 12. Then an arithmetic process is applied at a logic part 7 to give the control to the device to be controlled through a digital output device 13. For a change of the section of the part 8, a linkage is secured to the sequence program preserved at the CPU1 just operating a switch of a setting part 3. |
