Summary:PURPOSE:To easily know the condition of waiting and to easily analyze abnormality that a sequence does not advance forward, etc., by the waiting condition of a sequence program on a CRT. CONSTITUTION:When the waiting condition is obtained by sequence control macro 4 and 5 to be used in a sequence program 3, waiting condition data are registered to a sequence monitor table 8. A process input and output program 7 is operated with a constant period and executes the output of data to a plant 1 and the taking-in of the data. Then, the taken-in data are stored to plant data base 6 as a present value and a present status. The waiting condition data are taken from the sequence monitor table8 by a sequence monitor picture display program 10 and displayed on a CRT 11 together with the present status and data which are taken from the plant data base 6.
