Beckhoff automation engineers and TwinCAT developers

Digiventi provides TwinCAT developers who join your team to implement machine controls and resolve software bottlenecks. Work can cover a new controller application or changes to an existing Beckhoff installation.

• PLC programming: Develop IEC 61131-3 Structured Text in TwinCAT 3, with reusable function blocks and explicit machine-state logic.
• Operator interfaces: Build TwinCAT HMI screens for machine operation and diagnostics, with alarm handling and access permissions.

Specialists can review existing code and add tests around sequence transitions before commissioning.

EtherCAT specialists configure Beckhoff I/O and investigate communication faults that interrupt machine cycles. Bring one in when devices fail to reach the expected state or errors recur under production load.

The work covers topology checks, process-data mapping, Distributed Clocks configuration and cycle-time analysis. Engineers inspect working-counter errors and device diagnostics to distinguish configuration issues from physical network faults. They can also validate replacement terminals against the installed configuration and document recovery steps for maintenance engineers.

Beckhoff automation engineers develop TwinCAT motion-control logic and connect machine controls to surrounding systems. For axis changes, they review drive parameters and coordinate movement with machine-state logic.

• TwinCAT NC/PTP and NC I: Configure positioning or coordinated motion, including homing routines and fault-recovery sequences. Validate software limits against the machine's mechanical constraints.
• ADS and OPC UA integration: Exchange commands and production data with supervisory applications. Define interface contracts and connection-loss handling so external software does not leave control behavior ambiguous.

Support engineers trace existing TwinCAT applications to resolve recurring faults and implement controlled software changes. Commissioning support can include I/O verification and sequence testing, followed by fault diagnosis during machine trials.

For TwinCAT 2 to TwinCAT 3 upgrades or controller replacement, specialists assess library dependencies and hardware compatibility before proposing changes. They can prepare version-controlled backups and rollback procedures, then test the revised application against agreed machine behavior. Ongoing support can cover a maintenance backlog or investigation of intermittent failures.
