The following diagram shows the structure of the slave station's output data.
The output status for I/O Slave Stations from unit number 1 to 64 is specified
in addresses 000H to 003FH of variable type 81. The Serial Master Station's
input/output data is cleared when the power is turned OFF.
Example: Outputs 0 to 2 for Unit Number 1 Are OFF
0000 0000 0000 0111
When 0007H is specified in address 0000H, outputs 0 to 2 for unit number 1
are turned ON.

When writing Slave Station output data in a batch for a specified range of
node numbers, an error will occur if I/O Slave Stations that cannot communi-
cate are present. Errors will also occur under the following conditions.
• Using I/O Slave Stations with 16 inputs.
• Using I/O Slave Stations in scan list disabled mode that have not entered
the network.
• Using unregistered I/O Slave Stations in scan list enabled mode.
Write 0000 as the data for I/O Slave Stations that are not used or cannot com-
municate.
The following table shows the structure of the Slave Station I/O size (number
of points).

Lower byte Input size: 08H, 10H
Upper byte Output size: 00H, 08H
The I/O size data that is read depends on the setting status at the time the
data is read, as follows.
• In RUN mode without using the scan list: Reads I/O size of I/O Slave Sta-
tions that entered the network using entry processing.
• In SET mode with all I/O Slave Stations registered: Reads I/O size of I/O
Slave Stations during temporary registration in the scan list.
• Other setting status: Reads I/O size of I/O Slave Stations registered in the
scan list.
Example: WT30-SID16: 0010H
