PURPOSE:To improve the applicability from the viewpoint of constituting a ladder circuit by gathering information, which contacts in a circuit including an application instruction have, and combining and processing them in case of the application program. CONSTITUTION:In case of the circuit including the application instruction, a programmable controller gathers and processes contact information and starts the operation of the application instruction. If an application instruction has a format to turn on a contact group 5 of contacts B0-Bn in accordance with the number of turned-on contacts of a contact group 1 of contacts A1-An, the controller searches turned-on contacts of the contact group and counts them. When all contacts are checked, the controller controls contacts on a basis of the check result so that some of contacts in the contact group 5 of contacts B0-Bn are turned on. |
