In a system that connects a numerical controller (NC) unit to an operation board and to a plurality of remote I/Os with serial communication lines, the control method of the serial communication line between the NC unit and the operation board is similar to the control method of the serial communication line between the NC unit and the remote I/Os, so that the operation board can at times use the same communication lines as the remote I/Os to improve the flexibility of the system. The frame length and communication interval of data transmitted/received between the NC unit and the operation board are the same as those of data transmitted/received between the NC unit and the remote I/O. The operation board and the remote I/O can thus be connected to a common communication controlling portion of the NC unit.
An operation board--remote I/O communication controlling system for a machine tool controlling network, said network having an operation board for accepting input data from a user, a remote I/O for allowing communications with a remote machine tool, and at least one communications link connected to at least one of said operation board and said remote I/O, said communication controlling system comprising:
A machine tool controlling network comprising:
