摘要： PROBLEM TO BE SOLVED: To provide a programming device for a PC(programmable controller) which efficiently programs. SOLUTION: This device copies and connects sequence programs in a sheet unit by performing drag and drop of program connection among plural windows with a mouse when a new sequence program 121 is created from a division sequence program 21 of a program 20 in a sheet unit of a controlled object device. When a conventional part program is reused, it does not need such complicated operations as to show a list of files, to retrieve and select a file of object control functions, to show a sequence program itself and to display and designate a connection destination after retrieving the range of copy.

摘要： PROBLEM TO BE SOLVED: To reduce the labor of a user in the case of monitoring the state of a PLC. SOLUTION: An abnormality data requesting part 21 request the output of all data related with the abnormality of a PLC 10, and when a receiving part 22 receives code data from the PLC 10, a display control part 25 allows a display 26 to display contents meant by the code data by referring to a code interruption table 23, and allows the display 26 to display the interrelating code data by mutually arranging them by referring to a set code table 24.

摘要： PURPOSE:To easily and inexpensively measure the surface roughness of a part on the manufacturing site by measuring the surface roughness of an object to be measured on the basis of the contact resistance obtained when the contact element is applied to the object to be moved in parallel to the measuring surface thereof. CONSTITUTION:A contact element 1 is set in the square hole of an object 10 to be measured by an up-and-down shift cylinder 7 and subsequently applied to the object 10 by a shift cylinder 7. By this method, the contact element 1 is applied to the object 10 to be measured under definite pressure by a compression spring 2. Next, an origin position fixing cylinder11 is pulled back and a lateral shift base is moved in the right direction. At this time, the contact element 1 is not operated in synchronous relation to the lateral shift base because of the contact resistance with the unevenness of the measuring surface of the object 10 to be measured. A strain plate 3 is distorted by the contact resistance to distort a strain gauge 4. This strain quantity is read by a strain reader to measure surface roughness.

摘要： PURPOSE:To automate machining and inspection as consistent operation by providing a means which generates a signal by switching a compressed air flow passage when the stop side of a limit gauge reaches a specific position after the passage side passes and a means which detects said signal. CONSTITUTION:A figure shows a state which an inspection unit 15 decides as a normal state. The relative position relation between an air switching shaft 9 and a cylinder 8 when a stop gage 3 moves slightly by specific size from a position where it can not pass is shown in the figure and a return spring 13 is compressed; and the switching part 9a of the air switching shaft 9 is adjusted to face flow passages 12d and 12e so that compressed air passed through flow passages 12b, 12c and 12d from an air intake 12 is supplied to a vibration generator 6 from a flow passage 12e. At this position, a vibration generator 6 operates to generate vibration with a receiving plate 7 and a monitor amplifier 17 converts the vibration into an electric signal to decide that the inspection result is proper. Then when an inspection unit 17 is elevated, a plug gage 1 is returned by the return spring 13, the compressed air charged in the vibration generator 6 is discharged, respective component mechanisms finish preparations for next inspection.
