* Most of the settings on the computer will be adjusted to match the settings on the unit.

 

attention

The only device supported by the NQ series is HR. Also, writing to the NQ series HR is only supported by function code 06.

To use function code 06, uncheck the following settings in the Server application's communication details/other detailed settings.

 

c_plc_0944

 

 

attention

Modbus/TCP is used for communication with the NQ series. Therefore, the models that can communicate are limited to those that can use Modbus/TCP (such as NQ-MP8L).

For details on the applicable models, please refer to the device's manual.

 

 

Device settings

Configure the settings for the "NQ-MP8L". Settings are made using the switch on the device and the NQ Sensor Monitor.
 

1.Set the IP address using the rotary switch on the unit

setting

Setting contents

Rotary Switch x100

1

Rotary switch x10

0

Rotary switch x1

0

 

hint

The value specified by the switch will be assigned to the following "xxx" and used for operation.

 

・IP address: 192.168.0.xxx

-Subnet mask: 255.255.255.0

・Default gateway: 192.168.0.1

 

If all rotary switches are set to 0, the IP address will be "192.168.0.250".

 

 

hint

If you are using a model that does not have a switch on the main unit, you must set the IP address using the setting tool "NQ Sensor Monitor." Also, if you want to set the IP address of the NQ-MP8L from the setting tool, set the rotary switch to "600" (PGM-DHCP).

 

 

PC settings

Use the Server application to connect to the device for which you have set up communications.

 

1.Right-click "Application" - "Driver" in the tree and select Add Driver.
 

2.Select the following units from the displayed driver list and add them:

3.Open the properties of the added unit (U01) and click Communication Settings.

4.Configure the following in "PC Settings"

Setting contents

Unit IP Address

6.Select "Ping Test" to check if the ping goes through normally.
If you see a message like "Ping test is success～", the test was successful.

 

7.Click "Other detailed settings" under "Communication details"
c_plc_0950
 

8.Uncheck "Supports function code 16" and press the "OK" button.

c_plc_0951

 

hint

Normally, function code 16 is used to write to an HR device, but by unchecking the above, writing will be performed using function code 6.

This model only supports writing function code 6, so this setting must be unchecked.

 

9.Perform a connection test to check the connection

c_plc_0952

 

If a message such as "Connection OK" is displayed, the connection is confirmed.

 

 

About tag settings

The data output format varies depending on the local device and settings, so you need to configure the tag to best suit your situation.

As an example, we will introduce a configuration example for connecting a Keyence clamp-on flow sensor (FD-Q10C) to port 1 of the NQ-MP8L to obtain the instantaneous flow rate.

 

The output format of the FD-Q10C process data can be selected from the following four types.

- Instantaneous flow rate value

・Output 1 + Output 2 + Instantaneous flow rate value

・Instantaneous flow rate value + output 2 + output 1

・Instantaneous flow rate value (1/10) + stability level + output 2 + output 1

 

The output format can be selected using the configuration tool "NQ Sensor Monitor".
