10.2 Connection Objects
Setting up the transfer of signal values from one device to another is car-
ried out in XBuilder. This is made using connection objects or multi-
connection objects. After sending the XBuilder project (the gateway
application) to the Xenta 913, the signals are transferred at regular inter-
vals between the devices.
For examples on how to connect signals between devices using connec-
tion objects, see Section 8.3.2, “Adding a Connection Object”, on
page 66.
Conditions for Sending Values
In the properties pane for the connection object there is a Send Option
property.
The connection object can be configured to send the connected signal
under any of the following conditions:
• Periodically – the signal is always sent at a regular interval set in
seconds in the Period (s) box.
• Periodically if changed – The signal is sent if the value of the sig-
nal has changed. The signal is then sent during the next cycle of
the time period, as set in the Period (s) box.
• Initially and periodically if changed – The same as for Periodi-
cally if changed but the signal is also sent once when the device
first starts communicating.
10.2.1 Adding more Output Signals
Connection objects are used for reading one signal and transferring its
value to another signal. It is possible to transfer the same signal to sev-
eral other signals, by adding more output signals to the connection
object.
To add more output signals
1 In the system pane, right-click a connection object and click
Add Output Signal.
2 Type the name of the output, in the example
“Device2_Outdoor_Temp”.
3 Connect another signal to receive the transferred value.
