Overview

Task

The Service Interface is a synchronous communication mechanism to invoke an external service from a CNC program.

The external service can execute a number of different tasks e.g.:

• Process and/or archive machine and log data.
• Send emails about the successful completion of a program.
• Read out wireless dial gauges and return measured values to the CNC program.

Attention

To use the Service Interface in practice, 2 software components must be developed: 1. the external service and 2. the CNC program to invoke the service. For this reason, this functional description is only suitable for experienced users or software developers.

Requirement

The Service Interface uses Beckhoff’s ADS mechanism.

The requirements are therefore:

• TwinCAT 2.* with CNC Build >= V.2.11.2030.01, or
• TwinCAT 3.* with CNC Build >= V.3.1.3057.03
