Setting Method
Dummy Sensors are set using commands.
 Dummy Sensor Position Setting
This sets the position of the Dummy Sensor. After the position is set, the Dummy Sensor is enabled.
To execute the command, set the Command Type Setting Area write register (RWwn+2) to 15 hex
(as shown in List of Write Commands).
Set the Command Data 1 write register (RWwn+4) to n (the unit number you want to set for the
Dummy Sensor).
 How to Set Dummy Sensors
Set the bit that corresponds to the required unit number to 1.
To set the Dummy Sensors as units 4 to 6, as shown in the usage example above, set the
Command Data 1 write register (RWwn+4) to 0000 0000 0011 1000 binary or 38 hex.
To cancel a Dummy Sensor setting, set the corresponding bit to 0. To cancel all set Dummy
Sensors, set the Command Data 1 write register (RWwn+4) to 0000 0000 0000 0000 binary or 00
hex.
For detailed setting instructions, refer to 6-1-1 Input Data Assignments.

Command Communications with the E3NW-DS

The E3NW-CCL Communications Unit can be connected to a E3NW-DS with an E3NW-DS Connector.
Sensor Amplifier Units can be connected to an E3NW-DS and the PV, ON/OFF information, and
command response information from those Sensor Amplifier Units can be sent to the E3NW-CCL.
Up to 8 E3NW-DS Units can be connected, and up to 10 Sensor Amplifier Units can be connected to
each E3NW-DS. However, the maximum number of connectable Sensor Amplifier Units in the entire
system configuration is still 16, even when E3NW-DS Units are used.
You must set the unit number for any connected E3NW-DS through the unit number setting switches on
the E3NW-DS.
In the I/O map for the E3NW-CCL, the order for output values will be mapped as follows: Sensor
Amplifier Units connected to the E3NW-CCL followed by Sensor Amplifier Units connected to
E3NW-DS Units in ascending order of E3NW-DS unit numbers.

Error History

When an error occurs in the Communications Unit, information is stored in the error history in the
EEPROM.
Information for up to eight errors can be saved in the error history. When more errors occur, the oldest
entry in the error history is overwritten by the latest error information.
You can read the error history with a read command or clear the error history with a clear command.
If multiple errors occur at the same time, the priorities at which errors are stored in the error history are
listed in the following table.
