Connected Number of Sensors Setting
Registers the number of Sensors connected. By setting the number of Sensors, errors
can be detected in the configuration.
When the DIP switch pin 3 is turned ON, however, this rotary switch is disabled. Instead,
the values set from the DeviceNet Configurator or using explicit messages are enabled.
Note Fiber Amplifier Units (E3X-DA6TW and E3X-DA8TW) that are allocated two unit
numbers must be counted as two Units when counting the number of connected
Sensors.
