Document Type and Number:
Japanese Patent JP3186483
Kind Code:
B2
Abstract:
PURPOSE: To easily grasp the contents of a trouble, to quickly execute program debugging or the like and to suppress the reduction of processing speed by monitoring the contents of a register at every data processing and recording registered data.
CONSTITUTION: After editing a program, the edited program is transferred from a PLC interface controlling part 33 to a program storing part 21 through a supporting device interface controlling part 23. When the operation of the program is troubled, a device and a relative device are registered by a monitor information registering processing part 5. The registered data are transferred to a monitor registered information storing part 3 through the controlling part 23. A monitoring part 2 monitors a program arithmetic processing part 22 based upon the data. When a change is generated in the registered device, a monitor information monitoring part 2 transfers an arithmetic processing result obtained when the device is changed to a monitor result recording part 4.
