8.1 Automatic Mode

executed on the transmitter side. Program dnc-plus.exe can be executed on IBM PC or on a compatible computer. It ensures connection between transmitter and receiver with protocol. Its advantage over simple DNC connection is that it calculates the checksum by each program block and sends it to control. If the receiver detects an error, it asks for repetition and the transmitter sends the block again. Of this, the operator notices nothing what so ever, for it proceeds automatically. Contrary to simple DNC connection this method makes data transfer very safe, the possibility of mistaking (i.e., control receives false command due to error in data transfer channel) is minimal.

If the option FEW (Floppy Ethernet Winchester) is integrated into the control that is really an integrated PC (Personal Computer), then also action DNC FEW can be selected. Then program execution happens from the PC.

The programs sent in DNC must meet the following requirements:

–no divergence command can be used in main program (i.e. in the program, which is transmitted from external device), such as GOTO or M99 Pnnnn,

–subprogram or macro call is possible with the restriction that the subprogram or macro program must be in the control memory, it cannot be on external device.

Machining Start and Stop

The machining starts with the START button and stops with the STOP button in effect. If no program is selected for execution in automatic mode, and control is not in DNC state, the error message NOT EXISTING PROGRAM is displayed when starting automatic mode.
