Latest Patents

One of Hiraishi's latest patents is a ladder display system. This system includes a first controller with a first ladder program and a second controller with a second ladder program that performs input/output processing with the first ladder program. An input/output signal table generating unit creates a table that relates the input/output signals of both programs. Additionally, an external reference execution unit specifies a signal from the second ladder program and requests the transmission of part of the first ladder program. The ladder program output unit then transmits the relevant part of the first ladder program to the second controller, which is displayed by the ladder program display unit.

Another significant patent is a programmable controller. This device sets access rules regarding permission or denial of access to a first data storage unit during the execution of a second sequence program. The first sequence program is executed while accessing only the first data storage unit, while the second sequence program accesses both the first and a second data storage unit according to the established access rules.
