DeviceNet Remote I/O Communications
Remote I/O
Communications
Two-word with
Incident Light
Level Monitoring
Mode (Pin 1 OFF,
Pin 2 ON)
Up to 16 Sensors can be connected in this mode. The incident light level mon-
itor default setting is to monitor all the Sensors that are connected. By turning
ON pin 3 of the DIP switch, the number of Sensors being monitored for inci-
dent light levels can be changed from the DeviceNet Configurator or by using
explicit messages.
When the number of Sensors to be monitored is set, the incident light level is
monitored starting from the Unit next to the Fiber Amplifier Sensor Communi-
cation Unit up to the number of Sensors that is current set.
In addition to word m and word m+1, one word is allocated in the IN Area of
the master for each Sensors to be monitored for incident light level.
