PURPOSE:To recognize easily the executing course of the sequence program processing by stopping said proccessing at a set address after executing it by an amount equal to the set cycle number and executing the processing for each instruction from the set address to check and observe the processing state. CONSTITUTION:When a contact X0 of an input is turned on, the contents of a data register D0 in a sequence controller to a register D1. Then the contents of the D1 are compared with those of a register D2 when a contact M0 within the sequence controller is turned on. When the contents of the D1 are larger than those of the D2, a Y10 is turned on in the form of an output. Therefore it is possible to confirm five instructions, i.e., whether the input X10 is turned on; whether the contents of the D0 are transferred to the D1; whether the contact M0 is turned on; whether the contents of the D1 are larger than those of the D2; and whether the output Y10 is turned on respectively. |
