In scan list enabled mode, the scan list must be registered. If scan list regis-
tration is performed without the serial number check, I/O Slave Stations can
be replaced by simply setting the switches. Scan list registration must be per-
formed again when an I/O Slave Station is added regardless of whether the
serial number check is enabled, and also when replacing I/O Slave Stations if
the serial number check is enabled. The Serial Master Station performs wire-
less communications only with the I/O Slave Stations registered in the scan
list, preventing unwanted I/O Slave Stations from joining the network. If the
serial number check is disabled, replacement of the same node number with
the same model will not be detected.
Scan List Enabled
Set the function setting switch as follows (Serial Master Station only):
Bit 2: ON (scan list enabled)

In normal mode, input data is read, and sent to the Serial Master Station as is.
The input data is saved according to the polling timing from the Serial Master
Station. For example, after an input turns ON, if the input from the Serial Mas-
ter Station turns OFF during polling, the input OFF data is transmitted to the
Serial Master Station and the ON data input in the I/O Slave Station is not cor-
rectly transferred.
Set to the estimated maximum
number of nodes for the system.
Example: 5 nodes

added as required.
Simply set the frequency channel
and node number to easily add
any model to the network.
