Abstract

PURPOSE:To execute initialize operation and initialize program verifying opera tion by the same program by providing operation mode switching means to switch an initialize operation mode and an initialize program verifying operation mode. CONSTITUTION:Operation mode switching means 21 and 22 are provided to switch the initialize operation mode and initialize program verifying operation mode and the initialize operation and initialize program verifying operation is executed by the operation mode switching means 21 and 22. Namely, the operation mode switching means 21 and 22 can arbitrarily set any mode for the initialize operation or initialize program verifying operation. Thus, without using a host computer, the program can be executed as well by a conventional equipment.

[Problem to be solved by the invention] Conventional initialization program verification as described above With this method, there was a problem in that the information recorded after initialization had to be connected to a host computer and verified using a separately prepared diagnostic program.Additionally, a host computer was required at the production site. There were problems such as increased costs.

This invention was made to solve these problems, and the purpose is to provide an initialization program verification method that does not use a host computer and performs program verification using conventional equipment. [Means for solving the problem] The initialization program verification method according to the present invention has the following features:

1) and (22) are the first and second operation mode changeover switches, which switch between the initialization operation mode and the initialization program verification operation mode, and normally operate in conjunction with each other. FIG. 2 is a diagram showing an operation flowchart of the present invention.

In the horizontal initialization program verification method as described above, the first and second operation mode changeover switches (21) and (22) are set to the initialization side, that is, the contact (21a), the contact (21c), and the contact (22a). When the contact (2 2 c) is connected, it operates as before. On the other hand, in the program verification mode side, that is, in a state where the contacts (21a) and (21b) and the contacts (22a) and (22b) are connected. When the program starts running, it reads TSDB (8c). The read data is transferred to the first operation mode selector switch (2l).
