Function Summary
For general PLC, when the internal optical couples, relays or transistors are damaged, the
corresponding input/output terminals will be faulty. The only solution is to revise the program.
This is troublesome for the user and affects the production greatly;
XC series PLC breaks the one-to-one correspondence. The users only need to change the soft
component’s value by HMI, then the corresponding terminal will activate. Take advantage of this
improvement, the user need not replace the PLC or modify the original program in the condition
of PLC terminals damaged.
Before (Complicate and not effective)
Now (Simple, fast and effective)
Output Y3 is
broken
Solution 1
Revise the complicated
program
Solution 2
Change PLC
Output Y3 is
broken
Solution
Change the mapping
relation of Y3 and its
corresponding soft
component; use other empty
point, like Y4
