<p>PURPOSE:To relieve the processing of a host computer by transmitting a data from a numerical controller to a host computer automatically every time a specific code is read so as to eliminate the need for sensing at each sampling time. CONSTITUTION:When a CPU2 reads a numerical control command from an NC tape 8 and decodes the content and a G code being a specific code is inputted, the G code is stored in a register RG in a RAM4 and the data this time is stored. Then the CPU2 compares a specific code stored in a register RG in the RAM4 with the G code, and when they are dissident, the processing is continued according to a numerical control command and when they are coincident, a transmission request signal RS is set to logical 1 and the signal is transmitted to the host computer 1. When a transmission enable signal CS from the computer 1 is set, the content of the register RG and the data this time are transmitted. When the transmission is finished, the signal RS is set to logical 0 and the processings above are repeated.</p> |
