4.7.1 Purpose of I/O assignment using GX Developer
POINT
1. The I/O assignment setting becomes valid when the PLC is powered OFF
and then ON or the CPU module is reset.
2. The I/O assignment setting is necessary for changing the response time of
the input modules and the switch of intelligent function modules.
3. If any of the I/O modules other than the 16-point modules fails without I/O
assignment setting being made using GX Developer, the I/O numbers after
that module may change, leading to a malfunction. Therefore, it is
recommended to make I/O assignment setting using GX Developer.
