As an example of the dimensions of the existing control panel 210, for example, the height (vertical width) H is in the range of about 2300 mm and the horizontal width W is in the range of 800 to 1000 mm. As an example of the dimensions of the update control device 10, the height H and the width W are the same as those of the existing control panel 210, and the depth D is about 200 mm. According to the present embodiment, in the control system 11 in which the new IO unit 14 is attached to the existing control panel 210, the increase in installation space is suppressed by an increase of about 200 mm on the front side (front side) of the existing control panel 210. .

  Comparative Example 1 (conventional example) will be described with reference to FIGS. FIG. 10 is a perspective view showing that the existing control panel shown in FIG. 9 is converted into a relay terminal block and the renewal work is performed using the new control panel.

  In this comparative example, the space in the casing 212 of the existing control panel 210 accommodates both the new IO unit 14 and the update relay terminal block 270 (corresponding to the relay unit 20 described in the first embodiment). It is an example that is too narrow to do.

  Therefore, in order to perform the renewal work, the new control panel 250 that accommodates the new IO unit 14 is manufactured in advance. Then, the new control panel 250 is transported and installed near the casing 212 of the existing control panel 210. Then, the one-sided outer door 226 of the existing control panel 210 is opened, the external line connector 220 is removed from the existing IO unit 215, and the existing IO unit 215 is also removed. Then, the update relay terminal block 270 is arranged in the space where the existing IO unit 215 was arranged. Further, the single-open outer door 256 of the new control panel 250 is opened, and the new IO unit 14 and the update relay terminal block 270 are newly connected by the cable 266. In addition, the external line connector 220 is connected to the update relay terminal block 270. Therefore, it is necessary to secure a space for installing the new control panel 250, to wait for the renewal work until the new control panel 250 is manufactured, and to newly connect the outside line by the cable 266. There may be inconveniences such as the need to secure a significant external cable connection time.

  In addition, when the height of the update relay terminal block 270 is larger than the height of the existing IO unit 215 and the existing power supply and the existing electrical product are diverted, the update relay terminal block 270 may be used depending on the storage rate in the existing control panel 210. May not be stored in the existing control panel 210. In this case, the effect obtained in the above embodiment is extremely large.
