Property Signal Generator Aspect
You can use the Property Signal Generator aspect to generate a simulated value that
can be used to test a display, a display element, or any other client application that
subscribes for OPC items (object properties). The Property Signal Generator is only
intended for test purposes.
The Property Signal Generator aspect can generate a sinus formed wave, a ramp, a
random value or a static value.
Configuration Steps. To be able to use the Property Signal Generator there must be
a data source for the Process Portal OPC property to give the value to. A generic
OPC property together with a test OPC adapter delivered with the product can be
used as source.
The following steps create a data source and a Property Signal Generator with a
sinus wave.
1. Go to Control Structure and create a new object of type Generic OPC Server
Network, under the OPC 3rd party OPC support Object Type group. Give the
object the name TestAdapterNet.
2. In the Additional Arguments dialog, select the appropriate Connectivity Server
and but do not select any OPC server. Press Create.
3. Go to the Service Structure and view the Service Group Definition aspect on
the SG_TestAdapterNet object under the OpcDAConnector service. Select the
Special Configuration tab and enter ABB.AfwDsGenericTestAdapter.1 in the
Adapter field. Press Apply.
4. Go to the Service Provider object under the SG_TestAdapterNet object and
view the Service Provider Definition aspect. Select the Configuration tab and
check Enabled, then press Apply.
5. Go to Control Structure again. Create a new object of the type Generic OPC
Object under the TestAdapterNet object. Give the new object the name Pump.
