Abstract

PURPOSE:To eliminate the need for change of the software by preparing all programs in response to functions of plural remote I/O units and selecting one with a switch and using it. CONSTITUTION:A central processing unit (CPU) of a programmable controller (PC) reads and executes sequentially a program stored in a memory. An initializing processing section 11 applies initializing processing S1 of the PC at first after the start. Then the type of each remote I/O set to a switch provided to a printed board of each remote I/O in the step S2 of a selection section 12 is read. The type is compared in the steps S3, 4, 5 and type processings S4, S6, S8 provided in a remote I/O processing section 13 are executed depending on the corresponding type.

First, a program f corresponding to the functions of a plurality of remote I/Os and software including all the programs are configured as shown in FIG. 1, for example, and stored in the memory in the PO. A switch is provided on each of the printed boards of the plurality of remotes I10. Then, the PC selects the switch, and
The remote I/O function corresponding to the selected switch is processed.

る。First, in step fJ/, initialization processing is performed to bring the PC into the initial state. Next, in step 8J, a desired remote I/O is read. Next, in step S3, it is determined whether the function of the ft remote I10 read in step s2 is type A. If the determination result in step S3 is "Y1!ls", type A processing is performed in step F3. Further, if the determination result in step B3 is "NO", a full determination is made in step S as to whether or not the function of the remote I10 is of type B. This step S! If the determination result is "ygsJ," type B processing is performed in step S B.
If the determination result of r is "NO", it is determined in step S7 whether the remote I/O function is type 0 or not. If the determination result in step S70 is [Y11!8J, type C processing is performed in step at. below,
It is assumed that the steps for determining the type and the steps for processing are increased according to the number of remote I/O functions.
