As shown in FIGS. 1 and 2, the programmable controller (PLC) of the first embodiment has an "SE
L. "," LOCK "," 1 "," 2 "," 3 ",
"4", "5", "6", "7", "8", "9",
An operation unit 11 including switches of “A”, “B”, and “C” is provided, and a display unit 12 is provided. A main body 10 is mounted on the panel P1 in an embedded manner with one surface (front) exposed from the main body 1 (not shown).
An operation unit 11 and a display unit 12 are provided on one surface of the reference numeral 0.

In the examples shown in FIGS. 1 and 2, the display unit 12 is turned on when an input signal is input to the programmable controller and when an output signal is output from the programmable controller, so that the input / output state is changed. An input / output state display unit 121 for displaying a display; an operation mode display unit 122 for displaying an operation mode by turning on or blinking each time the operation of the programmable controller is in operation, during interruption, or when an operation error occurs; The programmable controller comprises a value display section 123 for displaying a numerical value such as a timer value, a count value, and a data value.
An input signal can be given to the programmable controller by pressing a switch of the operation unit 11.

Further, the main body 10 of the programmable controller is a completely closed housing having one surface slightly flange-shaped, and as shown in FIG. A locking portion 101 including a plurality of rows of locking protrusions is formed.

On the other hand, as shown in FIGS. 3 and 4, the attachment 1 is formed in a frame shape whose inner size is set slightly larger than the size of the outer peripheral side wall of the main body 10. A pair of extending portions 1a each extending from the outer surface to the back side
And a pair of tightening portions 1b which are respectively provided outside two opposing corners of the four corners, and the feet of the screw S protrude to the front side in accordance with the tightening of the screw S, and the inner surfaces of one of both side walls. A pair of claw portions 1c each formed and locked to the locking portion 101
And

Next, the mounting of the present programmable controller having the above configuration to the panel P1 will be described. First, the rear side of the main body 10 is inserted into the opening of the panel P1 from the front side until the outer peripheral edge 10a of the slightly flanged surface of the main body 10 hits the front of the opening edge of the panel P1. Push the body 10 in. Thereafter, the fixture 1 is inserted into the main body 10 from the rear side, and is pushed until it hits the rear surface of the opening edge of the panel P1. As a result, the panel P1 is sandwiched between the outer peripheral edge 10a of the main body 10 and the fixture 1, and the claws 1c of the fixture 1 are locked by the locking portions 101 of the main body 10, so that the main body 10, The controller is attached and fixed to the panel P1.
