摘要： An input/output device has a processor which processes data strings received by the device. When a data string is received, it is passed to a serial interface and a timing means. The serial interface generates a signal which interrupts the existing processing by the processor and causes the process to start processing of the newly received data string. At the same time the timing means measures the length of the data string and compares it with a predetermined length set by user-controllable data setting means. If the data string length reaches the predetermined length, the processor is triggered to stop processing the new data string and to recommence the processing it was performing prior to interruption. The unprocessed part of the new data string is stored in a memory.In this way, urgent data strings, which are generally short, are processed rapidly and longer data strings are processed after the urgent data strings. It is not necessary for the data string to contain any information to identify its length.

摘要： A built-in insulating element for electrically insulating a process portion from a control object and for transmitting a process result to the control object is provided in the output portion for transmitting the process result of a sequence controller to the control object. Further, a noise preventive element is provided in the output portion for preventing a noise voltage from coming in from the control object side and damaging the insulating element.

摘要： In a sequence program constructed by forming a ladder diagram on a display screen, an element corresponding to a minimum unit of the ladder diagram is arranged by a symbol element and a character element. Inputting and amending operations of the ladder diagram are performed by a first cursor for designating each element and a second cursor for designating the character element of the element designated by this first cursor.
