General Virtual Station

In General Virtual Station, different specific result reporting and tightening settings can be saved. Different filters can be created, filtering out specific results. In the tightening settings, characteristics like the tool unlocking behavior can be set. These configurations can then be assigned to virtual stations.

Unlock tool on loosening settings

Disable loosening settings

To ensure that a bolt cannot be loosened by mistake, use the disable loosening function. There are four disable loosening settings:

These settings are valid during the execution of a task. Loosening enables and disables depending on the setting and the status of the last tightening. For a new task the start state for disable loosening is set as follows:

The start state applies whenever a new task is assigned to a Virtual station or when a task starts again. The start state can differ depending on the type of task, described as follows.

Tightening program and Sync mode

Enable and disable of loosening follows the disable loosening setting and is set to the status of the last tightening.

Batch Sequence

During a batch sequence the enable or disable of loosening follows the disable loosening setting and is set to the status of the last tightening. This also applies when a batch goes to the next one within a batch sequence. If a batch sequence starts again, the loosening is enabled or disabled according to the start state for a new task.

Source Batch

Enable and disable of loosening follow the same procedure as described in Batch sequence. If an ongoing source batch starts again or if a new one is selected, the loosening is enabled or disabled according to the start state for new task.

Source Tightening (No batch control)

During a batch, enable and disable is set according to the status of the last tightening. If another program is selected, enable and disable is set according to the start state for new task. If any change of program, tool or socket is done, enable and disable is set according to the start state for new task.

Multispindle tightening

Enable and disable of loosening always follows the status of the last tightening. This is also applicable for a new sync mode.

Disable tightening settings

To make sure that an operator does not tighten a bolt by mistake there is a function called disable tightening. There are four disable tightening settings:

These settings are valid during the execution of a task. Tightening enables and disables depending on the setting and the status of the last tightening. For a new task the start state for disable tightening is set as follows:

The start state applies whenever a new task is assigned to a Virtual station or when the task starts again. The start state can differ depending on the type of task, as described in the Disable Loosening settings section.

When using tightening settings with STB, SRB, and TBP in radio shadow, there are some limitations:

• The disable loosening setting, After every operation, only works when the tool is connected to the controller. In radio shadow, the behavior defaults to On OK tightening.

• The disable tightening setting, After every operation, only works when the tool is connected to the controller. In radio shadow, the behavior defaults to After every tightening.

• The maximum consecutive loosenings setting only works when the tool is connected to the controller. The counter will not work, and the tool will not lock while in radio shadow.

Maximum consecutive loosenings settings

To ensure the operator does not loosen the bolt more than the allowed number of times, configure the tool to lock after reaching the maximum consecutive loosenings. You can set this value between 0 and 250.

• If set to 0, the operator can loosen the bolt an infinite number of times, and the tool will never lock.

• If set to a number greater than 0, the tool will count each loosening. Once it reaches the configured number, it will lock and prevent further loosenings.

The consecutive loosening counter resets with each tightening attempt, whether successful (OK) or unsuccessful (NOK).

When the tool locks, it cannot perform loosenings but can still perform tightenings. If an attempt is made to loosen, event 4021 – Too many consecutive loosenings will show. The Max consecutive loosening reached – 245 signal will also activate and can be sent to external systems via Fieldbus or shown on a stack light.

To unlock and reset the counter, an external system must trigger the signal Reset too many loosenings – 10151 via Fieldbus or an accessory. The Master unlock – 10005 signal can also unlock the tool for loosening but will not reset the counter. A tightening performed while loosening is locked will unlock the tool for further loosenings and reset the counter.

Allowing a disabled tool to unlock after loosening

• In the general virtual station configuration assigned to the virtual station to which the tool is connected, set the Unlock tool on loosening to On OK or Always.

To enable the setting above, the following conditions need to be met:

• The Disable loosening parameter cannot be set to Off or Always.

• The Disable loosening parameter cannot be set to the same value as Disable tightening.

• The tightening program used must have loosening enabled.

When the tool is locked for either tightening or loosening due to a disable state, it can be unlocked by any of the following input signals:

• Master Unlock - 10005

• Unlock Tool on Disable - 10059

• Unlock tightening on disable - 10149

• Unlock loosening on disable - 10150

It is not possible to unlock a disabled tool with the input signals ifLock tool on loosening is set to Always.

Assigning a configuration to a virtual station

Each virtual station can have its own configuration and multiple virtual stations can share the same configuration. A configuration must be assigned to a virtual station to become active.
