When the bit is set to 0, the multi-function input terminal is valid in the closed status and
invalid in the open status;
When the bit is set to 1, the multi-function input terminal is valid in the open status and
invalid in the closed status.
These function code are subject to bit operation. You only need to set the corresponding bit
to 0 or 1. Take F02.15 as an example, as shown in the following table:

The seventh bit is reserved and cannot be set. The specific displayed value does not mean
anything.
For example: To set the terminal X1 to reverse logic, you only need to set the 0
th
bit
corresponding to X1 to 1, i.e. F02.15=xxx xxxx1.
To set the terminals X1 and X5 to reverse logic, you only need to set the 0
th
bit
corresponding to X1 and 4
th
bit corresponding to X5 to 1. That is, 02.15=xxx 1xxx1.
