摘要:
In a method for transmitting data in a control system, a first station generates a data frame having a plurality of data fields. At least one data field to be filled with transmission data is clearly assigned to each further station. The data frame is transmitted as an outgoing data frame from one station to the next, with every further station filling the respectively assigned data field with transmission data. The last station returns the data frame as a returning data frame to the series of stations. The stations read extraneous transmission data from the data fields in the returning data frame. Preferably, the respective data fields are individually assigned to the stations.

The present invention provides a communication LSI for easily realizing mutually sending and receiving control system data and information system data by incorporating a control system I/O interface used when executing sensor monitoring and actuator drive control, an information system communication interface of Ethernet or others, and a data conversion CPU on one chip. Specifically, when sending control system data from a sensor connected to the control system I/O interface 107 to the Ethernet 106, the control system data stored in the memory 102 is converted to an Ethernet protocol by the CPU 101 and stored in the memory 102. The data converted to the Ethernet protocol is then sent to the Ethernet 106 from the information system controller 105 via the bus controller 104. On the other hand, when sending information system data to the sensor from the Ethernet 106, the reverse procedure of the aforementioned procedure is performed.

A data display/input method for a CNC apparatus without necessity of using a personal computer which has been served as a relaying device between the CNC apparatus and a host computer and also as a display device, and also capable of constructing an FA network system at low cost. A display screen of the CNC apparatus is split into first and second display areas so that information transferred from the host computer to the CNC apparatus is displayed in the first display area while information inputted to the CNC apparatus by the operator is displayed in the second display area. Display attributes in the CNC apparatus are switched in accordance with display attributes specified by the information transferred to the CNC apparatus from the host computer, whereby restrictions on a data display of the CNC apparatus are removed, permitting text data and graphic data to be displayed.
