PURPOSE:To improve the operability and to remarkably reduce the circuit forming time, by reading a circuit after programming on a CRT and taking the circuit as a basis. CONSTITUTION:When a request of use of circuit already made in a program memory of a programming device PSE1 with CRT or a programmable controller PC5 is made from a keyboard 3, a control section 4 displays the circuit on a CRT2. The circuit is corrected afterwards to form a new circuit. For example, when many same pattern circuits are desired to be formed, the key-in surrounded with dotted lines is unnecessary for the key-in operation as shown in figure through this method, and the circuits can be formed only with the key-in operation for an input and output number. Thus, the time required for key-in can remarkably be decreased. |
