Controlling apparatus for multi- input and output}

The present invention relates to a multi-input and output control device of the CC-LINK platform having a variety of input and output functions, and more specifically, to the power line and communication line by integrally installing the input and output boards of the field device performing a specific operation and operation for each process and line The present invention relates to a multi-input / output control device that can greatly simplify wiring and be implemented as a board having various kinds of input / output functions.

CC-LINK (Control & Communication Link) is an open field network that can respond to various user demands while simultaneously controlling various field devices by processing communication and control at high speed simultaneously.

Based on this CC-LINK, in the industrial field, an integrated control panel system for integrated management of field devices by conducting data communication with the integrated controller is connected to the control unit (mainboard) of various field devices performing a specific process. It is used. In this case, the field devices may include at least one input / output board and receive data through the input / output board or output response data for performing a predetermined operation and process.

That is, the conventional integrated control panel system must separately install at least one input / output board corresponding thereto when installing one field device.

In general, input / output boards of each field device are installed and used in a patch board for each process section or field device.

However, in the conventional integrated control panel system, when the I / O boards are installed in the wiring board, each of the input and output boards must be connected separately from the communication line and the power line drawn out from the wiring board, that is, because the communication line and power line per one I / O board must be installed separately. Communication line and power line), and wiring is separately installed between input / output boards, thereby increasing the quantity and length of wiring. In particular, since communication interference increases noise in proportion to its length, an increase in the length of the communication line causes a problem of data loss.

1 is an exemplary view showing input and output boards applied to a conventional integrated control panel system.

1, for convenience of description, three input / output boards corresponding to one field device will be described by way of example.

In this case, although not shown in the drawing board, the main board of the field device is installed in the wiring board 150, and the main board is connected to the input / output boards 101, 103, and 105 by the communication line 153. , 103 transmits the input data received from the main board to the field device through the input / output connection and the data cable, and the output board 105 transmits the output data received through the data cable to the main board.

As such, the conventional integrated control panel system must separately connect the communication line 153 and the power line 151 to each of the three input / output boards 101, 103, and 105, and the input / output board 101. ), (103), 105, because the connection line 151, 153 is increased, the number of wiring increases. In particular, in FIG. 1, for the convenience of description, three I / O boards have been described as examples, but four or more I / O boards may be configured according to the amount of I / O data. In this case, the wiring is further increased.

In addition, as the length of the communication line 153 increases, noise increases and data loss occurs. In particular, due to the high temperature and structural complexity of the process due to the nature of the industrial site, such data loss occurs more frequently.

In addition, each of the input / output boards 101, 103, and 105 is a communication connection unit 113 to which a communication line 153 is connected, a power supply connection unit 111 to which a power line 151 is connected, and an input / output connection unit 115.

That is, the elastic portion 10 is supported by the support plate 11 to the rear cover 4, the plate spring 13 having an elastic force is installed to face the main board (5).

In addition, bolt fastening holes 15 are formed at both ends of the elastic part 10.

At this time, in the present invention for the convenience of description, the elastic portion 10 is described as an example consisting of a support plate 11 and the leaf spring 13, but the configuration of the elastic portion 10 is not limited to this, the main board ( 5) may be applied in various configurations to support the back cover (4) elastically.

FIG. 13 is a side cross-sectional view illustrating when the elastic part of FIG. 12 is coupled to the main board and the rear cover.

Looking at the function of the elastic portion 10 with reference to Figure 13, the main board (5) is coupled to the rear cover (4) but has elasticity to the rear (X) by the elastic portion 10, the main board ( When the slot board 6 is coupled to the first slot 31 of 3), the slot board 6 is welded to the protruding surface of the protruding support 45 of the rear cover 4.

In this state, if the force (a) is applied to the rear (X) to install the input and output board 9 in the input / output slot 61 of the slot board (6), the main board (5) also has a force ( b) is received, the elastic portion 10 is also received by the force (b) of the main board (5), the elastic portion 10 is compressed.

In addition, the main board 5 and the slot board 6 are finely moved to the rear side X by the compression of the elastic part 10, and the slot board 6 is finely moved to the rear side X. The board 6 is supported by the protrusion support 45 so that the input / output board 9 is inserted into the input / output slot 61 of the slot board 6.

As described above, in the present invention, the various connectors and the LEDs 81 are all installed in the same direction, in detail, facing the front of the user, so that the assembly and the release can be easily performed.

In addition, since the multi-input / output controller 1 can drive a plurality of input / output boards using one power line and communication line, wiring is simplified, and in particular, as the length and quantity of communication lines are reduced, noise is suppressed to reduce data loss. Can be saved.

In addition, in order to drive three I / O boards, a total of three CPUs, communication and power connectors, and I / O connectors must be installed, one for each I / O board. In (1), since only one CPU, communication and power connector, and input / output connectors are installed when driving three input / output boards, it is easy to manage and maintain, and installation costs can be reduced.

In addition, the multi-input / output control apparatus 1 of the present invention can be implemented as boards having various input / output functions in one enclosure because a plurality of input / output boards are installed.
