During the software test of the i7000 test platform, the test cannot be run after the press is pressed down to the bottom?

解决方法

Solution: The reason is that the lower limit switch of the cylinder is not in place, and the I7208 card does not get the signal of the lower limit switch in place, which causes the software to read 1. When the lower limit switch of the cylinder is adjusted to the proper position, the lower limit switch LED will light up, and the software reads 0 at this time, and the test can be run.
