Property access for read and write
The default value of this property is defined in the "Refresh from server at server change
" configurator of this object.
Tha data group of the OPC
client (the PmaOpcDaClientGroup
object) that has this property set to true
, requires the ongoing update of all its data from the OPC
server. The server sends the value to such client automatically at a change of the value on the server.
Because the update of the requested data could pass uncertainly very fast, the parameters for the update can be specified - see UpdateRate
property and Deadband
var oOpcGroup = pMe.Pm("/OpcClient/Group1");
var bUpdate = oOpcGroup.Update;
// Reading from the property
oOpcGroup.Update = true;
// Writing into the property
