A method and system for generating programming code andor configuration data for programmable controller and the networks on which they operate is disclosed. A secondary fuse indicating circuit is electrically connected to a main fuse circuit in parallel with a main fuse link, and includes a secondary fuse wire link which is disposed adjacent the combustible substance. The top piece includes an inner post that a central passage and a threaded surface for engaging the inner hub. After the first latch circuits finish latching all the gradation data, the n gradation data are simultaneously supplied to the DA converter from the first latch circuits through the second latch circuits. The implement position sensor is configured to generate an implement position signal indicative of a position of the implement. Embodiments of the present invention further include a method and computer program product for processing a computer program in substantially the same manners described above.
