8.3.2 Adding a Connection Object
Now it is possible to transfer various values from one device to another
by connection objects.
As ComsFail and online signals are used for generating alarms in
RTU4, these signals from the Modbus network and the energy meter are
transferred to RTU4.
To add a connection object
1 In the system pane, right-click the folder where you want to add a
connection object. In the example, ACME_Gateway-Engineering-
Connection_Objects.
2 Point to New, point to Object, and then click Connection Object.
3 Right-click the new connection object, click Rename, and then
type the name. In the example “Link_ComsFail”.
4 Expand the connection object. In the example, Link_ComsFail.
5 In the system pane, drag the sending signal to the From signal in
the connection object. In the example, drag the ACME_Gateway-
Engineering-ComsFail signal to the ACME_Gateway-Engineer-
ing-Connection_Objects-Link_ComsFail-From signal.
6 In the system pane, drag the receiving signal to the To signal in the
connection object. In the example, ACME_Gateway-Engineering-
RTU4_Signals-Usage_Link_ComsFail signal to the
Link_ComsFail-To signal in the connection object.
7 In the system pane, click the required connection object. In the
example, Link_ComsFail.
Tip
• If required, change the unit of the Usage_Tot_real_power signal
to kW.
Note
• By using connection objects you can connect signals of
No Category to signals of any other category and vice versa.
