Optional clientSubscriptionOptions

clientSubscriptionOptions: ClientSubscriptionOptions

Options to set up a common subscription for monitoring items in an OPC UA client (optional). See interface ClientSubscriptionOptions of node-opcua-client package.

If a subscription option is not specified, its default value is defined as follows:

{
   requestedPublishingInterval: 100,
   requestedLifetimeCount: 60,
   requestedMaxKeepAliveCount: 10,
   maxNotificationsPerPublish: 0,
   publishingEnabled: true,
   priority: 1
}
remarks

As all monitored OPC UA data item sources share the same client subscription, subscription options are applied to all of them. If you need different options for different monitored items, define them in separate OpcuaConnector instances.

Optional connectionOptions

connectionOptions: OPCUAClientOptions

Options to set up an OPC UA client (optional). See interface OPCUAClientOptions of node-opcua-client package.

See type UserIdentityInfo of node-opcua-client package.
