<p>PURPOSE:To make a real-time monitor display by dispersedly performing logical operations which are high in load. CONSTITUTION:In a logical operation interpreting processing 24, a logical operation processing that programmable controllers(PLC) should be put in partial charge of on the basis of a logic table is recognized and a program to be inserted is generated by program generation 25. The generated program is written in a program of the corresponding PLC and the respective PLCs gather state information according to inserted programs and performing the necessary logical operations. A work station gathers the arithmetic processing results of the respective PLCs and further performs a logical operation for them to generate information to be displayed.</p> |
