Show the input ports or output ports are on the short-circuit or not.
If the little block becomes Red,the according port is on the short-circuit; if it’s still black,the
according port is not on the short-circuit.
For example, we define the IN01 as the “X-axis Zero Signal”, and when the X axis touched the
limited switch, it will show as below:
But,the status is active, doesn’t mean that the according signal is active. For example,we
reverse the signal’s polarity, and moves the X axis away from the limit switch, the status light
and IO block show as below: the X-axis zero signal is active,and IN01 Block is not on,because
IN01 is not conductiong with COM-.
Column 2 and Column 4:
Figure 3-4 Input 01 is conducting with COM-
Figure 3-5 The status is active but IN01 is not ON
