# Main functions

## Tightening process control

The minimum product configuration allows you to control tightening processes in the course of product assembly.

Multiple tools can be used at each station for performing several tightening operations, each of which can be configured to meet particular requirements.

## Industrial automation

- After signing-in a product at a station, Smart AMS determines which tightening steps need to be performed.

- Tightening steps are determined by program configuration; their selection may depend on PR Codes retrieved from MES.

- A special stack light or a lamp on the operator panel can be used to indicate that the tightening workflow is in progress.

- When in automatic mode, Smart AMS automatically selects the corresponding tightening program in the controller and waits for the operator to perform tightening.

- If the operator makes an OK tightening, Smart AMS automatically proceeds to the next tightening step, if any.

- If the operator makes an NOK tightening, Smart AMS can prompt for retry as many times as specified by system customizer. If all retries have been failed, Smart AMS acts according to one of the following strategies:
  Strategy 1: Abort the job and sign out the product.
  Strategy 2: Let the operator skip the bolt by using the corresponding button.
  Strategy 3: Let the operator re-do the whole workflow at the station.
  Strategy 4: Advance to the next bolt automatically.

The workflow is completed when there are no tightening jobs to perform or when the product is signed out.

Lamps show the operator whether the overall product status is OK or NOK. A Stack Light can be configured for this.

## Centralized configuration storage

The Smart AMS Config application includes configurations for stations, accessories, function options, and process recipes.

A web user interface allows you to apply configurations by using your web browser.

## Access control

You can specify different credentials for signing in to Smart AMS Manager and Smart AMS Config.

## Emergency mode

Smart AMS supports emergency mode that can be activated by the operator in case of errors: wrong recipe configuration (for example, tightening program does not exist), problem with receiving MES build data, etc. An error state can be indicated by a system error lamp.

If an error occurs, the operator can switch the station to emergency mode by using a key switch. A special lamp is reserved for indicating that the station is in emergency mode.

In emergency mode, all tools at the station will be unlocked, and predefined tightening programs or manually selected tightening programs will be used, provided the operator panel or socket selector is configured. When all the controllers are switched back to automatic mode, the station will return to automatic mode.

## Distributing and activating a single-station tightening task

Configurations specify tightening tasks to be performed depending on product properties. Smart AMS automatically selects the tightening task, unlocks the tool for tightening, and sets the corresponding tightening program.

## Manual tightening task control

Smart AMS allows the operator or plant maintenance team to skip the entire product or a particular bolt in it.

## MES API

You can use the built-in MES API for exchanging data between Smart AMS and a manufacturing execution system (MES), including the retrieval of build data, making sign-in requests, and reporting of result data. The transfer of tightening traces is supported.

## Monitoring API

It provides status information about the running Smart AMS instance. You can use this API to monitor live data for your reports and dashboards.

## Station dependencies

You can specify dependencies between stations within a selected assembly line or across multiple assembly lines.

## Synchronization between PLC and barcode scanner

Products can be signed in by using a barcode scanner or PLC. Smart AMS can be configured to send scanned barcodes to the PLC when operating in manual mode.

## Various product sign-in options

Products can be signed in by using a barcode scanner, PLC, or MES.

## Connection check

Smart AMS monitors the connection to all devices. When the connection changes state, the corresponding entry is written to the Event Log.

## Avoiding duplicates at product sign-in

You can choose to prevent a new product from being signed in if the product ID is the same as that of the product that was signed in immediately before it.

## Avoiding completed products sign-in

You can choose to prevent a new product from being signed in if it has already been successfully processed.

## Integration with SQS3

Smart AMS is capable of communicating with SQS3 for data transfer and interdependencies among stations in assembly lines.

## Integration with ToolsNet 8

Smart AMS is capable of transferring result data (OK, NOK, NYD) to ToolsNet 8.

## Integration with ILT

Smart AMS is compatible with Industrial Location Tethering solutions to ensure the tools will only work where you want them to.
