CompoWay/F Node Number Setting
0
Sets the CompoWay/F node number. Set in combination with DIP switch pin 4.
CompoWay/F Communications Mode Setting
0
Sets the CompoWay/F communications mode.
Connected number of Sensors Setting
1
Registers the number of Sensors connected. By setting the number of Sensors,
errors can be detected in the network configuration.
This switch is disabled when DIP switch pin 3 is ON. The value set using
CompoWay/F message communications is enabled instead.
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.
CompoWay/F Node Number Setting
This switch sets the CompoWay/F node number. The CompoWay/F node
number is set by setting the rotary switch in combination with DIP switch pin 4.
