METHODS

Refer to the open62541 documentation for the semantic of classes and methods.

Variant

$variant = OPCUA::Open62541::Variant->new()
$variant->isEmpty()
$variant->isScalar()
$variant->hasScalarType($data_type)
$variant->hasArrayType($data_type)
$variant->setScalar($p, $data_type)

VariableAttributes

$attr = OPCUA::Open62541::VariableAttributes->default()

Server

$server = OPCUA::Open62541::Server->new()
$server = OPCUA::Open62541::Server->newWithConfig($server_config)
$server_config = $server->getConfig()
$status_code = $server->run($server, $running)

$running should be TRUE at statup. When set to FALSE during method invocation, the server stops magically.

$status_code = $server->run_startup($server)
$wait_ms = $server->run_iterate($server, $wait_internal)
$status_code = $server->run_shutdown($server)

ServerConfig

$status_code = $server_config->setDefault()
$status_code = $server_config->setMinimal(port, certificate)
$server_config->clean()
$server_config->setCustomHostname($custom_hostname)

Client

$client = OPCUA::Open62541::Client->new()
$client_config = $client->getConfig()
$status_code = $client->connect($url)
$client_state = $client->getState()
$status_code = $client->disconnect()

ClientConfig

$status_code = $client_config->setDefault()
