Conformance to EC Directives
Applicable Directives
· EMC Directive
Concepts
EMC Directive
The Digital Sensor Communications Unit is an electrical device that is built into other machines. To enable more easily building it into other machines, it has been checked for conformity to EMC standards.* EMC-related performance of the Unit will vary depending on the configuration, wiring, and other conditions of the equipment or control panel on which it is installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.

Note: Applicable EMC (Electromagnetic Compatibility) standards are as follows: EMS (Electromagnetic Susceptibility): EN 61326-1 EMI (Electromagnetic Interference): EN 61326-1
Conformance to EC Directives
The Digital Sensor Communications Unit complies with EC Directives. To ensure that the machine in which the Unit is used complies with EC Directives, the Unit must be installed as follows:
· The Unit must be installed within a control panel. · You must use reinforced insulation or double insulation for the DC power supplies for
communications, internal power, and I/O. The DC power supplies must provide stable power even when a momentary power interruption of 10 ms occurs in the input. We recommend using an OMRON S8JX-series Power Supply.* · Products complying with EC Directives also conform to the Emission Standards (EN 61326-1). Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control panel used, other devices connected to the control panel, wiring, and other conditions. You must therefore confirm that the overall machine or equipment complies with EC Directives. · Compliance was confirmed for I/O wiring of less than 30 m.
Conformance with the EMC Directive was confirmed when using the recommended power supply.

4-3 Connecting the Unit Power Supply

To connect the E3NW-CCL to the CC-Link network, the Unit power supply is required. The E3NW-CCL does not require an I/O power supply.
The method for supplying power to the Unit is described below.

4-3-1 Precautions on Supplying Unit Power
Consider the following points on the allowable current and voltage drop on cables and connectors and
the placement of the power supply used to supply power to the Units.
Precaution on Cable Voltage Drop
Make sure that the power supply voltage to the slave farthest from the power supply is within the allowable fluctuation range.
Supplying Power to Units from Multiple Power Supplies
Using multiple power supplies to supply power can allow you to reduce the line current, reduce voltage drop, and decrease cable size. It also helps to maintain system stability in the event of a power supply problems.
Power Supply Problems
You must decide how to place your power supplies and how to group them depending on whether you want to stop the entire system when a power supply problem occurs or if you want to avoid stopping the entire system when possible. If you want to avoid stopping the entire system, install power supplies in multiple locations and divide the slaves into groups. This will also help to reduce voltage drop and enable you to use smaller cables.

4-3-2 Unit Power Supply Specifications
Use a standard power supply that meets the following specifications.

Item Output voltage Output ripple Output current
Isolation

Specification 24 VDC 10% 600 mVp-p Must be able to supply current that is higher than the total sum of the current consumed by all slaves. Between output and AC power supply and between output and frame ground

We recommend using an OMRON S8JX-series power supply for the Unit power supply to the slaves.
Precautions for Correct Use
· The Unit power supply also provides the I/O power for the inputs on slaves with e-CON connectors. When calculating the output current for the Unit power supply, always include the current consumption of the E3NW-CCL and the current consumption of all Sensor Amplifier Units in the Unit power supply consumption current.
· Make sure that the power supply has sufficient capacity to handle the inrush current when the system is started.

6-2-1 Dummy Sensor Registration

Outline of Function
Application
If the number of used Sensor Units or Sensor Unit numbers are changed (e.g., when device options are changed), the I/O assignments for the host device would also change, which requires modifications to host programming. By registering Dummy Sensors you can prevent these changes in I/O assignments and eliminate the effect changing Sensor Unit numbers might have on host programming.
The following is an application example. 1. Registers are always allocated to detect 16 connected Amplifier Units. 2. If this function is not used and there are no Amplifier Unit reservations, the data for Amplifier
Units 1 to 3 are assigned to registers S1 to S3. 3. If Amplifier Units 4, 5, and 6 (temporary names) are added next to Amplifier Unit 2, the register
assignments will change. (The data for Amplifier Unit 3 will no longer be stored in register S3, but in register S7 instead.) You can use Dummy Sensors to prevent the location of existing Amplifier Unit data from being moved when an Amplifier Unit are added as shown in the above example.
If you want to add Amplifier Units in the future as shown in the figure below, you can set Dummy Sensors to registers S4 to S6 to eliminate the need for any changes to host device programming when the additional Amplifier Units are actually installed.

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.
6-2-2 Command Communications with the E3NW-DS The E3NW-CCL Communications Unit can be connected to a E3NW-DS with an E3NW-DS Connector. 6
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.
6-2-3 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.

7-2-3 Handling Communications Units for Replacement
Every Unit (the CC-Link master and E3NW-CCL Units) is part of the network. If a Unit malfunctions, this can affect the entire network and therefore must be repaired as soon as possible. We recommend keeping replacement Units available in order to minimize the time needed to restore network functionality if required.
Precautions when Replacing Units
Be aware of the following points when replacing a malfunctioning Communications Unit. · After replacement, check to confirm that there are no problems with the new Unit. · If you are returning a defective Unit for repair, be sure to write down any details of the problem and
send the information along with the defective Unit to your nearest OMRON representative. · For poor contacts, wipe down the contacts with a clean 100% cotton cloth soaked in industrial
alcohol.
Settings after Replacing Units
After replacing a Unit, be sure to set all switches and other settings to be the same those in the previous Unit.

A-1 Using Commands for Communications

The Communications Unit can use read and write registers to perform communications with commands to perform more detailed data exchange. Using commands for communications allows you to read and write the status of a Sensor Amplifier Unit or change its settings.
1 Reading the Sensor Amplifier Unit Data
(1) Store the parameters for the data you want to read into the Data Category/Command Number Word and Data Number Word, and then turn ON the Command Request Bit.
(2) After communicating with the Sensor Amplifier Unit, the Command Completed Bit turns ON and the results of the communications are stored in Command Response Word. Read data is stored in the Read Data Words.
(3) When the Command Request Bit is turned OFF, the Command Completed Bit also turns OFF.
2 Writing Data to the Sensor Amplifier Unit
(1) Store the parameters for the data you want to write into the Data Category/Command Number Word, Data Number Word, and Write Data Words, and then turn ON the Command Request Bit.
(2) After communicating with the Sensor Amplifier Unit, the Command Completed Bit turns ON and the results of the communications are stored in the Command Response Word. The Read Data Words will be reset to 0.
(3) When the Command Request Bit is turned OFF, the Command Completed Bit also turns OFF.
