2. SIO Through Mode
If the SIO through mode is to be used, refer to the operation manual on serial communication (Modbus version).
In this mode, the Gateway R unit exchanges data with the host master in units of bytes (at the specified baud rate). It
also exchanges data with the controller unit at the baud rage of 230.4 kbps. In other words, communication data is
passed to the host and subordinate devices through the Gateway R unit at different baud rates (according to the settings).
The communication mode of the host (Modbus/RTU or ASCII) is automatically detected by the controller unit.
Caution
1. The baud rates of 9600 bps and 19200 bps cannot be set in this mode.
2. If this mode is to be used, set the user setting switch SW2 on the Gateway R unit to the ON (right) position.
