[0002]

2. Description of the Related Art In a temperature controller, for example, a large number of parameters to be set are prepared. For example,
The control parameters include proportional band, integral time, and derivative time, as well as lower limit alarm, upper limit alarm, cycle time, on / off operation hysteresis, heater burnout alarm, digital filter, process variable offset, and the like. Therefore,
When setting a parameter, the parameter items are sequentially called, the setting value corresponding to the parameter item is determined, and the parameter is registered (determined).

[0003]

The prepared parameters do not always have all items set, but are generally required depending on the setting position, for example, the final user, the set maker, or the design / manufacturer. It may or may not be necessary. In particular, since the minimum parameters required by the final consumer are usually the least, it is nothing but the complexity of the setting operation that many unnecessary parameters are called by the final consumer, and the operation speed is high. There is a risk that it may interfere with sex and induce operational mistakes.

An object of the present invention is to provide a parameter setting device which solves the above problems of the prior art and facilitates the operation and handling of parameter setting.

[0005]

According to the present invention, a plurality of groups to which each parameter item should belong are defined, and the code of each parameter item belonging to each group and the data of the registered set value corresponding thereto are provided. Writable / readable setting memory to be stored; one of the group codes is selected, and all parameter item codes belonging to the group code are sequentially called one by one or grouped at once A group selection section that is displayed based on the setting memory in a format; a parameter item selection section that sequentially selects one of all displayed parameter item codes; and a parameter item that is sequentially selected And a setting unit for storing the data of the set value in the setting memory as registered set value data after setting the set value.

[0006]

According to the present invention, the group selection section allows the parameter items to belong to, for example, a group related to the final consumer,
When the group related to the set maker or the group related to the design / manufacturer is selected, all parameter item codes belonging to the group code are displayed based on the setting memory. In addition,
The display of all the parameter items can be performed by sequentially calling and displaying them one by one, or by displaying them all at once. Next, the parameter item selection unit sequentially selects one from among all the displayed parameter item codes, and each time, the setting unit determines the setting value related to the selected parameter item. Then, it is stored in the setting memory as registered set value data.

It is a writable / readable memory. here,
First, second, and third groups are defined. The first group relates to the final consumer, and includes parameter items such as proportional band, integration time, and differential time. The second group relates to the set maker, and includes, for example, the parameter items belonging to the first group and the lower limit alarm, upper limit alarm, cycle time, on
Items such as OFF operation hysteresis and heater burnout alarm. The third group is related to the designer / manufacturer, and is, for example, items such as parameter items, digital filters, and process variable offsets that belong to the second group.

Reference numeral 6 denotes a mode selector which selects each mode of operation and setting and causes the display unit 6 to display it via the control unit 4. A group selector 1 selects one of the group codes, and displays all parameter item codes belonging to the group code on the display 6 based on the setting memory 5 via the controller 4. Reference numeral 2 denotes a parameter selector which sequentially selects one of all parameter item codes displayed on the display 6. Reference numeral 3 denotes a setter, which sets the set values for the sequentially selected parameter items, and then stores the set value data set in the setting memory 5 via the control unit 4 as registered set value data.

The mode selector 7, the group selector 1, the parameter selector 2, the setter 3, and the display 6 shown in FIG. 1 are functional representations. Actually, the front panel of the embodiment shown in FIG. As shown in the front view of FIG. 1, the first display is composed of various operation keys, which are a selection key 11, a shift key 12, a down key 13, an up key 14, and a 4-digit segment type display element.
