SINUMERIK Connection Properties

host (string, required)

Hostname or IP of the Sinumerik device

Example: "192.168.2.60"

port (integer, required)

Port of the Sinumerik device

Default: 4840

Example: 4840

resourcePath (string)

Path of the Sinumerik server

Default: ""

Example: ""

username (string)

Username for Sinumerik server

Example: "user"

password (string)

Password for Sinumerik server

Example: "user"

timeout (integer)

Timeout, in milliseconds

Default: 1000

Examples: 1000, 2000

options (object)

Properties of the options object:

defaultSecureTokenLifetime (integer)

Lifetime of the secure token. Specified in milliseconds.

Default: 3600000

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

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)

This element must be one of the following enum values:

• None

• Sign

• SignAndEncrypt

Default: "None"

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)

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)

If a connection attempt failes, retries will be performed with growing delays in between. The following parameter 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 of the first retry. Consecutive retries will randomly take longer delays.

Default: 1000

maxDelay (integer)

Maximum delay of a retry.

Default: 60000

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
