Radio nodes
Add PC Node supporting S2 and LCR
The S2 nodes are used in the Boomerang system to build radio networks, where measuring data are transmitted from measuring S2 nodes to S2 PC node which in turn delivers the data to the system using a serial COM port on the server.
To create a COM port through network a LAN adapter is needed.Installation of the virtual COM port shall be done according to the LAN adapter’s manual.
The S2 PC node requires the following settings to be defined:
Parameter
Description
Name
Unique module name
Node net
Radio net ID, programmed into the nodes
Serial port
The serial port the PC node is connected to
Available groups
Groups to which the module may be assigned. At least one of them must be selected.
Advanced
Advanced settings shown or hidden
Ping time (ms)
The maximum time the system waits for an answer from the radio network with no radio links.
Extra timeout for every node route (ms)
The additional time the system waits for an answer from the radio network for every radio link present on the path.
Fill in the fields.
Please note that an S2 PC Node must always have node ID = 1.
Use the “Test” button to check if the system detects the PC node and if its settings are correct.
The examples of test results are shown below.
Incorrect COM port or PC node not answering to requests.
The settings of PC node connected do not match (PC Node ID must be 1).
All settings are correct.
If the test ended successfully, click OK and sign. Please note that the settings of a PC node are always checked before the node is created so the system will not allow you to add a PC node for which the test is unsuccessful.
The PC node shall appear in the system tree view area.
Add S2 measuring node
To add the sensors in S2 radio network, right click the S2 PC node and select “Settings”.
A PC node settings form is opened, shown below. Please note it has a “ComErr Filter” field where you can set the number of consecutive readings from the unit that can be lost without triggering a communication alarm.
In the radio network, sensors are connected to measuring S2 radio nodes so to add a sensor you have to add a measuring S2 node first. To do so, right click the PC Node and select “Add new node…”.
Select the radio node ID and enter its name. If you will leave “Confirm contact with the node” checkbox selected which is recommended, the system will contact measuring node and will read its sensors. If the checkbox is not selected, the check is not done.
Click OK and sign.
If the “Confirm contact with the node” checkbox was selected, a message shown below will be displayed for a moment, during the time when the system tries to communicate with a measuring node over radio.
If the communication with the measuring node was successful then a sensor installation dialog will be displayed.
This dialog will look differently depending on the number of sensors connected to the node and their types.
S2 Standard node - Temperature (digital)
Click OK.
A “Sensor settings” dialog is opened.
Fill in all tabs of sensor settings as described in 20.3.
Click “Confirm” and sign. Click “Skip install” if you want to go back to initial settings form shown above.
The new sensor shall appear in the PC node settings view and the system tree view.
S2 Standard node - Relative humidity and temperature (digital)
Click OK.
A “Sensor settings” dialog is opened for RH sensor.
Fill in all tabs of sensor settings as described in 0.
Click “Confirm” and sign. Click “Skip install” if you want to go back to initial settings form shown above.
This type of sensor measures RH and T so sensors settings dialog is displayed again, this time for the temperature sensor.
Fill in all tabs of sensor settings as described in 20.3.
Click “Confirm” and sign. Click “Skip install” if you want to go back to initial settings form shown above.
The new sensors shall appear in the PC node settings view and the system tree view.
S2 PT100 node - 2xPT100 or 2xPT1000
Click OK.
A “Sensor settings” dialog is opened for PT100 or PT1000 sensor.
Fill in all tabs of sensor settings as described in 20.3.
Click “Confirm” and sign. Click “Skip install” if you want to go back to initial settings form shown above.
This type of node may have two sensors connected so sensors settings dialog will be displayed again, if the second PT100/PT1000 sensor is installed.
Fill in all tabs of sensor settings as described in 20.3.
Click “Confirm” and sign. Click “Skip install” if you want to go back to initial settings form shown above.
The new sensors shall appear in the PC node settings view and the system tree view.
S2 IOG2 node
The S2IOG2 node is offered in 3 versions:
S2IOG2 0-10V 3xVoltage + Temperature (digital)
S2IOG2 4-20mA 3xCurrent + Temperature (digital)
S2IOG2 Contact 3xContact + Temperature (digital)
The example below presents the settings for a 4-20 mA version with temperature sensor connected. The settings for the other versions are the same and the only difference are the units used (V or 1).
Click OK.
A “Sensor settings” dialog is opened for temperature sensor similar to standard S2 node with a digital temperature sensor.
Fill in all tabs of sensor settings as described in 0.
Click “Confirm” and sign. Click “Skip install” if you want to go back to initial settings form shown above.
This type of node may have three current (voltage or short circuit in other versions) sensors so sensors settings dialog will be displayed again, three times.
Fill in all tabs of sensor settings as described in 0.
Click “Confirm” and sign. Click “Skip install” if you want to go back to initial settings form shown above.
The new sensors shall appear in the PC node settings view and the system tree view.
