Switching Method for Setting Number of Sensors Connected
Bit 05 gives the status of DIP switch pin 3, which controls the method for reg-
istering the number of Sensors connected. When this bit is OFF, pin 3 is OFF,
and when the bit is ON, pin 3 is ON.
Number of Sensors That Can Communicate
Bits 08 to 12 give the number of Sensors that are currently able to communi-
cate between 1 and 10 Hex (1 to 16 decimal). This setting enables the user to
check how many Sensors are communicating normally when an error occurs.
Mobile Console Communications Flag
Bit 13 turns ON when the Mobile Console is connected to the Communication
Unit. When the Mobile Console is connected, the Configurator or explicit mes-
sage communications cannot be used to perform setting and monitoring oper-
ations.
Sensor Communications Error Flag
Bit 14 turns ON when the number of Sensors registered as connected does
not match the number of Sensors that can communicate, or when a communi-
cations error occurs after communications have been established with the
Sensors.
Sensor Communications Flag
Bit 15 turns ON when communications are established with the Sensors.
Note Fiber Amplifier Units (E3X-DA6TW, E3X-DA8TW) that are allocated two unit
numbers are allocated two bits of ON/OFF data and are counted as two Units
when counting the number of Sensors.
