Modbus Studio

Test and diagnose Modbus TCP before committing the configuration to PLC code. Validate live register data, engineering types and write behavior, then generate the MB_CLIENT or MB_SERVER solution for TIA Portal V21 from the same project.

Workflow

Test first.
Generate second.

TIA Portal generation uses the same tags or server registers first tested in Modbus Studio, helping reveal address and data type problems before they enter the PLC program.

Connect

Select the local adapter and connect to the intended device, or prepare a server register map with realistic test values.

Validate

Read, poll and write registers while inspecting raw frames. Confirm addresses, Unit ID, data types, scaling and byte order.

Generate

Create the FB, call FC, structured data blocks and address documentation, then import the client or server into the selected V21 project.

Compatibility & scope

Current early-access target.

The current build focuses on a transparent Modbus TCP workflow. The intended CPU, partner device and client or server role are checked before testing.

Protocol: Modbus TCP client and server with practical read/write validation
Engineering platform: TIA Portal V21 with Openness installed and the Windows user authorized
TIA communication: Generated MB_CLIENT V6.0 or MB_SERVER calls, data and diagnostic status
Engineering functions: Adapter selection, ping, polling, writes, frame diagnostics, typed address maps and scaling
Generated result: Named PLC values, protocol data areas, communication blocks and commissioning address reference
Validation status: Early access — device, CPU, firmware and project compatibility are reviewed before testing

Modbus TCP Client demo

From live tags to TIA Portal code.

Watch Modbus Studio validate a real device and generate the MB_CLIENT structure for TIA Portal V21, including the FB, call FC, data blocks, scaled values and quality information.

Modbus TCP Server demo

From register map to a working PLC server.

See Modbus Studio create and test a typed register map, then import its MB_SERVER logic, PLC data areas and readable address documentation into TIA Portal V21.

Check your device compatibility.

Tell us which PLC, firmware, TIA Portal version and Modbus device you use, plus whether the PLC should be client or server. We will review the use case and reply with suitable test steps or known limitations.
