Abstract
A system for controlling a machine at a remote place is constituted such that, when repairs and a change of a mechanical part of an apparatus on the remote place side are performed and changing of a program for a programmable sequencers for driving and controlling the apparatus is performed, contents of a change of the program thus performed are sent to a computer on the main office side and checked and changed on the main office side to make a correct program, and the correct program is sent to the controlling device on the remote place side.
Claims5
A system for controlling a machine at a remote place, characterized in that, when repairs and/or a change of a mechanical part of an apparatus having a programmable sequencer for driving and controlling the apparatus on the remote place side are performed and a change of a program for the sequencer is performed, contents of a change of the program thus performed are sent to a computer on a main office side over a public telephone circuit and checked and/or changed on the main office side to make a correct program, and the correct program is sent to said controlling device on the remote place side over the public telephone circuit and inputted to said controlling device.
A method for controlling a device at a first location, the method comprising the steps of:
- providing a programmable sequencer for driving and controlling the device,
- performing a modification of the device at the first location,
- performing a modification of the program for the programmable sequencer at the first location to thereby produce a modified program,
- sending contents of the modified program to a computer at a second location,
- checking and correcting contents of the modified program at the second location to thereby produce a corrected program,
- sending the corrected program to the sequencer at the first location, and
- inputting the corrected program to the sequencer at the first location.
A method for controlling a device at a first location, the method comprising the steps of:
- providing a programmable sequencer for driving and controlling the device,
- performing a modification of the device at the first location,
- performing a modification of the program for the programmable sequencer at the first location to thereby produce a modified program,
- sending contents of the modified program via telephone to a computer at a second location,
- checking and correcting contents of the modified program at the second location to thereby produce a corrected program,
- sending the corrected program via telephone to the sequencer at the first location, and
- inputting the corrected program to the sequencer at the first location.
An apparatus for controlling a device at a first location, the apparatus comprising:
- a programmable sequencer for driving and controlling the device,
- modification means for performing a modification ofthe program for the programmable sequencer at the first location to thereby produce a modified program,
- transmission means for sending contents of the modified program to a computer at a second location,
- correction means for checking and correcting contents of the modified program at the second location to thereby produce a corrected program,
- transmission means for sending the corrected program to the sequencer at the first location, and
- input means for inputting the corrected program to the sequencer at the first location.
