## addLinkUnit()

int cascading::CascadeManager::addLinkUnit | ( | in int | linkId,
|  | in string | host,
|  | in string | login,
|  | in string | password,
|  | in string | newPassword
| ) |  |

Put a new link unit under this primary unit's control.

The login credentials must have administrator privileges on the link unit. They are only used to establish a trust relationship between primary and link unit and not stored.

This method can also be used to re-authenticate a link unit that denies access. In that case the linkId and host parameter must exactly match the existing values.

Parameters

  linkId | The ID for the new link unit
  host | The link unit's host name or IP address
  login | The administrator login for the link unit
  password | The administrator password for the link unit
  newPassword | The new default administrator password for the unit. This is needed for adding a link unit that still has default settings and requires a password change. Otherwise it can be left empty. `login` must be the default admin.

Returns
  NO_ERROR The operation was successful
  ERR_INVALID_PARAM One of the parameters had an invalid value
  ERR_UNSUPPORTED_ON_LINK_UNIT This unit is currently a link unit and can't have link units of its own
  ERR_LINK_ID_IN_USE The specified link ID is already in use
  ERR_HOST_IN_USE The specified host is already in use
  ERR_LINK_UNIT_UNREACHABLE Connection to the link unit failed
  ERR_LINK_UNIT_ACCESS_DENIED The credentials for the link unit were invalid
  ERR_LINK_UNIT_REFUSED The remote unit refused to become our link unit because it's a primary unit itself
  ERR_UNIT_BUSY This unit is currently busy with handling another request
  ERR_NOT_SUPPORTED This device does not support PDU linking
  ERR_PASSWORD_CHANGE_REQUIRED The specified link unit requires a password change
  ERR_PASSWORD_POLICY The new password did not meet the requirements
  ERR_LINK_UNIT_COMM_FAILED Communication with the link unit failed
  ERR_LINK_UNIT_NOT_SUPPORTED Link unit does not support cascading
  ERR_FIRMWARE_VERSION_MISMATCH The firmware version of the link unit does not match that of the primary unit

## addLinkUnit2()

int cascading::CascadeManager::addLinkUnit2 | ( | in int | linkId,
|  | in string | host,
|  | in string | login,
|  | in string | password,
|  | in string | newPassword,
|  | in boolean | disableStrongPasswordReq
| ) |  |

Put a new link unit under this primary unit's control.

The login credentials must have administrator privileges on the link unit. They are only used to establish a trust relationship between primary and link unit and not stored.

This method can also be used to re-authenticate a link unit that denies access. In that case the linkId and host parameter must exactly match the existing values.

Parameters

  linkId | The ID for the new link unit
  host | The link unit's host name or IP address
  login | The administrator login for the link unit
  password | The administrator password for the link unit
  newPassword | The new default administrator password for the unit. This is needed for adding a link unit that still has default settings and requires a password change. Otherwise it can be left empty. `login` must be the default admin.
  disableStrongPasswordReq | if `true`, this disables the strong password requirements on the link unit if `newPassword` is set

Returns
  see addLinkUnit

## addSecureSerialLinkUnit()

int cascading::CascadeManager::addSecureSerialLinkUnit | ( | in int | linkId,
|  | in string | installKey
| ) |  |

Add a serial link unit (ScalePoint Base).

As a special case, link ID 1 is used to pair the primary unit on the "internal" RS485 bus. It will not be added to the list of link units.

Parameters

  linkId | The ID for the new link unit
  installKey | The install key from the Base unit's label

Returns
  NO_ERROR The operation was successful
  ERR_INVALID_PARAM One of the parameters had an invalid value

## finalizeLink()

void cascading::CascadeManager::finalizeLink | ( | in string | token | ) |

Finalize the link with this link unit.

Parameters

  token | same authorization token as used for requestLink()

This method should only be called by the primary unit in order to acknowledge the establishment of the link to the link unit and finalize the link build-up. The linking will only take effect once the link unit received this acknowledgement.

If this method fails, you will get the ACCESS_DENIED status for this link unit and you will have to re-authenticate it.

## getLinkPortStatus()

Check which type of link units this unit supports.

Returns
  vector with supported link unit types

## getSupportedRoles()

vector< Role > cascading::CascadeManager::getSupportedRoles | ( |  | ) |

Check which cascading roles this unit supports.

Returns
  vector with Roles that are supported by this unit

## releaseLinkUnit()

int cascading::CascadeManager::releaseLinkUnit | ( | in int | linkId | ) |

Release a link unit from this primary unit's control.

Parameters

  linkId | The ID of the link unit

Returns
  NO_ERROR The operation was successful
  ERR_INVALID_PARAM The specified link ID is invalid

## requestLink()

int cascading::CascadeManager::requestLink | ( | in string | token | ) |

Request to make this unit a link unit and put it under the remote primary unit's control.

This method is usually called by the primary unit when adding a new link unit. The link will only be established once finalizeLink() is successfully called.

Parameters

  token | Authorization token for future requests

Returns
  NO_ERROR The operation was successful
  ERR_UNSUPPORTED_ON_PRIMARY_UNIT This unit is a primary unit and can't become a link unit
  ERR_NOT_SUPPORTED This device does not support PDU linking

## setPrimaryUnitSettings()

int cascading::CascadeManager::setPrimaryUnitSettings | ( | in PrimaryUnitSettings | primaryUnitSettings | ) |

Set settings for the primary unit.

Parameters

  primaryUnitSettings | Primary unit settings

Returns
  NO_ERROR The operation was successful
  ERR_INVALID_PARAM At least one of the parameters had an invalid value

## unlink()

void cascading::CascadeManager::unlink | ( |  | ) |

Release this link unit from the remote primary unit's control.

This method is usually called by the primary unit when releasing a link unit. This unit will become a standalone unit.
