The configuration data of the slaves must be registered to the QJ71AS92 before it is
operated in the protected operation mode.
Slave registration to the QJ71AS92 can be performed by the switch operation in the
following (1) and (2).
However, the data registered to the QJ71AS92 are lost when the programmable
controller is powered on or the CPU module is reset. To store the registered data,
perform operation up to (3). The data are written to the EEPROM of the QJ71AS92.
(1) Put the QJ71AS92 in the configuration mode and assign
addresses to the slaves.
If the CM LED is off, press the MODE switch until the CM LED is lit.
Alternatively, turn Y16 ON.

TIP
When assigning the slave address with the QJ71AS92 connected to the slave of
slave address 0, please make sure that only one slave of slave address 0 is
connected to it.
The QJ71AS92 will not perform slave address assignment when being connected
with more than two slaves of slave address 0
