OpcuaConnection
host
(string, required)
host
(string, required)Hostname or IP of the OPC UA device
Example: "192.168.2.60"
port
(integer, required)
port
(integer, required)Port of the OPC UA device
Default: 4840
Example: 4840
resourcePath
(string)
resourcePath
(string)Resource Path of the OPC UA server. Please note that this should be set to a valid value as some OPC-UA servers experience issues when connecting without one
Default: ""
Example: ""
username
(string)
username
(string)Username for OPC UA server
Example: "user"
password
(string)
password
(string)Password for OPC UA server
Example: "user"
timeout
(integer)
timeout
(integer)Timeout, in milliseconds
Default: 1000
Examples: 1000
, 2000
certificateFile
(string)
certificateFile
(string)Absolute path to the client certificate file
Example: "/connectware_certs/cybus_client.crt"
privateKeyFile
(string)
privateKeyFile
(string)Absolute path to the client private key file
Example: "/connectware_certs/cybus_client.key"
checkHostReachable
(boolean)
checkHostReachable
(boolean)Checks if a low level TCP connection can be made to the configured host and port
Default: false
maxMonitoredItemsPerCall
(integer)
maxMonitoredItemsPerCall
(integer)If non-zero, multiple monitoredItems (i.e. multiple endpoints/nodes) will be registered in groups of maximum size of this given number. This is a server configuration property that can be queried on the server at nodeId: ns=0;i=11714. If this value is zero, no maximum value is assumed and all endpoints will be registered in one call.
Default: 0
options
(object)
options
(object)Properties of the options
object:
defaultSecureTokenLifetime
(integer)
defaultSecureTokenLifetime
(integer)Lifetime of the secure token. Specified in milliseconds.
Default: 3600000
requestedSessionTimeout
(integer)
requestedSessionTimeout
(integer)OPC UA sessions may survive TCP connection breaks and are only deleted if no message from a client is received within the timeout period. Specified in milliseconds.
Default: 3600000
transportTimeout
(integer)
transportTimeout
(integer)Secure channel creating timeout, used before connecting or reconnecting to an OPC UA host. Has an impact on when a deviation is thrown as reconnect is first trying to connect to the host.
Default: 60000
endpointMustExist
(boolean)
endpointMustExist
(boolean)Specifies if the connection is strictly meant for the given endpoint. If false and the endpoint doesn’t exist, a reasonable default endpoint is automatically chosen.
Default: false
messageSecurityMode
(string, enum)
messageSecurityMode
(string, enum)This element must be one of the following enum values:
None
Sign
SignAndEncrypt
Default: "None"
securityPolicy
(string, enum)
securityPolicy
(string, enum)This element must be one of the following enum values:
Aes128_Sha256_RsaOaep
Basic128
Basic128Rsa15
Basic192
Basic192Rsa15
Basic256
Basic256Rsa15
Basic256Sha256
None
PubSub_Aes128_CTR
PubSub_Aes256_CTR
Default: "None"
watchInterval
(integer)
watchInterval
(integer)For observing connection breaks, a connection watchdog runs regularly. Short intervals guarantee short notice on break but lead to higher load. Specified in milliseconds
Default: 30000
connectionStrategy
(object)
connectionStrategy
(object)If a connection attempt fails, retries will be performed with increasing delay (waiting time) in between. The following parameters control how these delays behave.
Properties of the connectionStrategy
object:
maxRetry
(integer)
Maximum number of connection retries in case of failure.
Default: 1000000000
initialDelay
(integer)
Delay (waiting time) of the first connection retry (in milliseconds). For subsequent retries, the delay will be increased by a factor of 2, and also by a potential random increase according to the parameter randomisationFactor.
Default: 1000
maxDelay
(integer)
Maximum delay (waiting time) to wait until the next retry (in milliseconds). The delay (waiting time) for any subsequent connection retry will not be larger than this value. Must be strictly greater than initialDelay.
Default: 30000
randomisationFactor
(number)
This parameter controls added randomisation to the retry attempts. Must be a number between 0 and 1. If set to 0, retries will be performed with exponentially growing delay until maxDelay. If set to 1, a maximum noise will be added to the retry delays.
Default: 0
Additional restrictions:
Maximum:
1
