Stopping Registration of All I/O Slave Stations

Select to either register all I/O Slave Stations automatically by specifying the
highest I/O Slave Station node number, or register specified I/O Slave Sta-
tions by specifying the I/O Slave Station node numbers individually. When reg-
istering all I/O Slave Stations at the same time, it is recommended to set the
I/O Slave Station node numbers in the same frequency in sequence from
node number 1 up to the number of connected nodes. Before registering, start
up all the connected I/O Slave Stations in RUN mode.
Registering All I/O Slave Stations Automatically
All the I/O Slave Stations up to the highest node number are registered.
Bit 8: OFF (register all I/O Slave Stations automatically)

Registering Specified I/O Slave Stations
The I/O Slave Station for the node number specified at the Serial Master Sta-
tion is registered. Set the special function switch from OFF to ON, and then
OFF again.
Bit 8: ON (register specified I/O Slave Stations)
ON
1 2 3 4 5 6 7 8 9 0
The serial number is registered at the same time as the corresponding I/O
Slave Station. The serial number is the product's unique number, i.e., no two
serial numbers are the same. This setting has the advantage of preventing
mistaken Slave recognition even if a WT30 Terminal with the same channel
(frequency), same node number, and same model is in the radio signal range.
The disadvantage is that I/O Slave Stations that are replaced must be re-reg-
istered.
When the serial number check is enabled (bit 9 is ON), the I/O Slave Station's
serial number is registered in the Serial Master Station.
Bit 9: ON (serial number check enabled)
ON
1 2 3 4 5 6 7 8 9 0
The serial number is not registered when the scan list is registered. This set-
ting has the advantage of not requiring I/O Slave Stations to be re-registered
from the Serial Master Station after replacement. The disadvantage is that
mistaken Slave recognition may occur if a WT30 Terminal with the same
channel (frequency), same node number, and same model is in the radio sig-
nal range.
When the serial number check is disabled (bit 9 is OFF), the I/O Slave Sta-
tion's serial number is not registered.
Bit 9: OFF (serial number check disabled)
ON

Scan list registration cannot be completed if the power is not turned ON for all
the I/O Slave Stations, or the node numbers are not assigned sequentially, or
if the I/O Slave Stations are not within the radio signal range. Use the follow-
ing settings to stop scan list registration if required. When registration of all I/O
Slave Stations is stopped, scan list details will not be written to EEPROM
unless this operation is performed.
