摘要： PURPOSE:To contrive the reduction of a line load by giving a data of line occupancy order to each slave station from a master station and allowing each slave station to recognize the transmission timing of its own station according to the sequence data when the transmission start command from the master station is received so as to send a data. CONSTITUTION:The master station 1 sends an initial command I and transmits a start command S. The initial command is the combination of station addresses and represents that a slave station 2 sends a data in the order. Both the commands I,S are sent to all the slave stations 2, 2... through a D line 3 from the master station 1. When the transmission is finished, the slave stations 2 send a data without command from the master station 1 sequentially. The data is sent to the master station 1 by using a U-line 3 and supervised by the function of a supervisory equipment in the slave stations 2.

摘要： PURPOSE:To reduce operations for preparing a table by enabling to have a clear calculating formula definition using item names and eliminating limit for the form of the table to be prepared as well, even in the case of a complicated table in which items conventionally impossible calculating formula definition are formed in plural steps. CONSTITUTION:A means for preparing the table of an editing object, means for editing the table, means for performing the calculating formula definition and means for performing defined calculation are provided on a hardware system. The means for performing the calculating formula definition is provided with an item setting means for setting the frame of the prepared table as an item corresponding to designation inputted from an input device 4a, item name/ data corresponding relation preparing means for preparing and preserving corresponding relation data showing corresponding relation between item name data expressing the item name inputted in the frame set as the item and data belonging to the item so as to be the object of calculation, and means to define the calculating formula while defining the item name data of the set item as formula elements as they are.

摘要： PURPOSE:To prevent the generation of malfunction due to operator's practice by changing the expression format of inquiry in each time when a system requires an oprator's instruction even when the meaning of the inquiry is the same as a preceding case. CONSTITUTION:Plural kinds of expression formats for at least either one of an inquiry message from the system and an operator's response to the message are previously stored. A display control part 6 selects and displays a different expression format ut of the stored plural kinds of expression formats in each display a message or a response on an output device 7. Consequently, the genera tion of malfunction due to oprator's practice can be reduced as less as possible and the accuracy of operation can be improved.
