# Interfaces

## MES interface

Smart AMS provides interfaces, based on WebSocket connections, to sign in products, to retrieve product data (build data) from MES, and to send result data to MES. The interfaces are customizable on demand.

## Controller and tool support

Smart AMS is compatible with the following Atlas Copco controllers and tools: Power Focus 4000, Power Focus 6000, MicroTorque MTF6000, PowerMACS 4000, STwrench, ICB, ITB, and PF6 Flex System.

## PLC interface

Smart AMS provides a PLC interface via TCP IP communication to line PLC using AMS PLC Product Trace Protocol to track product sign-in and sign-out. The interface is customizable on demand.

## Product scan support

As an alternative to signing-in a product by PLC or MES, the system allows the operator to sign it in by using its barcode. In this case, a compatible scanner must be connected. You can use a scanner connected to the tightening controller, integrated into the tool, or connected to the Smart AMS Server by using a LAN connection.

## Modbus/TCP

Smart AMS is compatible with Modbus TCP converters, allowing you to connect stack lights, buttons, horns, and other peripheral devices. Only Modbus devices that support the Read Coils (function code 1) and Write Single Coil (function code 5) functions can be used with Smart AMS.
