Objects
• This object detect communication status with E3NW-ECT and sensor amplifiers.
• When the Communication Busy bit is ON, communications are in progress between the Sensor
Communication Unit and the Sensor Amplifiers. In this case, do not send new SDOs to the Sensor
Amplifiers.
If the Communications Error bit turns ON, the set value for the number of Sensors does not agree with
the number of Sensors that are actually connected. Check the set value and the connected Sensors. If
you are using Dummy Sensors, set the number of Sensors to the total of the actual number of Sensors
and Dummy Sensors.
• Sub-index1: Number of Sensors Setting
• This object use to set sensor number include dummy sensors. Set the number of Sensors to
register to the number of Sensors that are actually connected plus the number of Dummy
Sensors.
• Sub-index2: Number of Sensors with Dummy
• This object detect number of sensors recognized by E3NW-ECT (with dummy sensors).
• Sub-index3: Number of Connected Sensors
• This object detect number of sensors recognized by E3NW-ECT (without dummy sensors).
