[0007]
In addition, when checking signal names in the same signal state, there is a problem that it cannot be checked unless a plurality of screen pages are switched.
[0008]
Furthermore, when performing an operation test of the inverter device and an operation test of a peripheral device connected to the inverter device, there is a problem that an operating environment must be actually constructed.
For example, in order to confirm the operation of the inverter device when ON or OFF is given as an input signal, an input signal is assigned to each input terminal, a sequence for inputting a signal to the outside is assembled, and each input terminal is It was necessary to input a command. Further, when the user forms a sequence around the inverter device, in order to confirm that the circuit connected to the output terminal of the inverter device operates normally, the inverter device in which each output terminal is turned ON or OFF is used. It was necessary to create a test condition or to replace the inverter device with another device for testing.
Furthermore, when performing an operation test of a plurality of inverter devices and an operation test of a peripheral device connected to the inverter device, there is a problem that the above-described confirmation must be performed for each of the plurality of inverter devices. Was.
[0009]
The present invention has been made to solve the above-described problems, and a first object is toAn inverter device capable of identifying and displaying a signal name assigned to an input terminal or an output terminal and a signal name not assigned to an input terminal or an output terminal.
[0013]

Output signal allocating means, and output terminal output means for outputting information created by the output signal allocating means to the output terminal group, Wherein an input terminal or the output terminal to indicate means, an input signal name or an output signal name assigned to the input terminal or output terminal, the inverter device designed to display the signal state at the same time,
The setting unit enables setting of a virtual signal state of the input signal or the output signal, and the input signal allocating unit overwrites the input signal set by the setting unit on the virtual signal state, Further, the output signal allocating means overwrites the output signal set by the setting means with a virtual signal state. A nonvolatile memory, wherein the inverter control means stores the virtual signal state of the input signal overwritten by the input signal allocating means and the virtual signal state of the output signal overwritten by the output signal allocating means in the nonvolatile memory The inverter device according to claim 3, wherein the inverter device is operated.
