Title:
PROGRAMMABLE CONTROLLER
Document Type and Number:
Japanese Patent JP3829905
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a PLC by which new control function parts on process control can easily be generated on a user side through the use of compiler-type language and especially an existed hardware PLC user can function-block only the necessary part of software property if necessary.
SOLUTION: MPU 101 which controls a whole module, a first RAM 103 which temporarily stores a system work and stores a user program, a non- volatile ROM 102 storing a system program for executing a module function and a second RAM 104 are provided in the CPU module 1 of PLC. In the second RAM, information required for generating instances being real operation control function parts based on a class registered in the non-volatile ROM, an instance number, a quotation source class number, operation timing setting and the like are stored in addition to the on/off state of a peripheral I/Q unit and an operation result by the user program, for example.
