| RX | Cancelling a roving. After an operator puts down the roving from the scale, the application will write the number of scale (1 or 2) into the I/O tag. | Co | Write | ||||||
| Number of spools on the lines. I/O tag is in the format "C1;C2;C3; … Cn;", where Ci represents an integral number that indicates number of spools on the line i. Example: "626;42;0;78;562;489;28;55;" | TxtI | Read | ||||||
| NC | Reset the counters of spools on the lines. Write any valid value, to reset the counters. The control unit will send message in the format "C1;C2;C3; … Cn;", where Ci represents an integer number that indicates the number of spools which were included on the line i since the most recent information on the number of spools (see PC). This message will be a new value of I/O tag with the address NC. | TxtO | Write |
