PLC can write data for commanding if the command semaphore has the value FALSE. When all commanded data has been written, the PLC sets this element to the value TRUE. CNC writes the data requested by the GUI if the request semaphore is FALSE and then sets this element to TRUE. PLC reads the data requested by the GUI if the request semaphore is TRUE. The PLC sets this element to FALSE after the data has all been accepted in the PLC. |
