The configuration of the INVEOR DAXI controller in combination with Siemens S7-300, S7-1200 and S7-1500 PLCs requires steps to ensure that the system communicates and functions correctly. In this article we will discuss the configuration process, presenting each phase, from hardware preparation to final testing.
Hardware and software requirements
Before starting the configuration, let's make sure we have:
- INVEOR DAXI Controller.
- Siemens PLC: S7-300, S7-1200 or S7-1500.
- TIA Portal software in a version compatible with the respective Siemens controller.
- Suitable communication cables (e.g. Profinet or RS485 depending on the protocol).
- Technical documentation for both devices.
1. Preparation of the INVEOR DAXI controller
1.1 Physical connection
- Power supply: Connect the INVEOR DAXI controller to the power source according to its technical specifications.
- Communication interface: Use appropriate communication ports, such as Profinet (Ethernet) or Modbus RTU (RS485), depending on the project requirements.
1.2 Configuration of factory parameters
- Connect your computer to the INVEOR DAXI controller using the dedicated cable.
- Use the software provided by the INVEOR manufacturer to set the basic parameters:
- Communication address (e.g. IP address for Profinet or ID in Modbus RTU).
- Transmission speed (e.g. 9600, 19200 baud).
- Communication protocol (Profinet, Modbus RTU).
2. Siemens PLC configuration in TIA Portal
2.1 Creation of a project in the TIA Portal
- Open TIA Portal and create a new project.
- Add a PLC (S7-300, S7-1200, S7-1500) to the project by selecting the appropriate model and version.
2.2 Profinet network configuration
- Go to tab Devices & Networks.
- Add the Profinet device - INVEOR DAXI controller.
- Enter the IP address of the INVEOR DAXI controller (consistent with the previously configured address on the device).
2.3 Mapping of inputs and outputs
- Assign the process data of the INVEOR DAXI controller to the corresponding PLC memory areas:
- Inputs: e.g. engine operating status data.
- Outputs: e.g. start/stop commands, change of speed.
3. PLC logic programming
3.1 Creation of a data block
- Create a data block (Data Block) in the TIA Portal to store the communication parameters and statuses of the INVEOR DAXI controller.
3.2 Creating the control programme
- Add logic blocks in the LAD/FBD/STL language to support communication with INVEOR DAXI.
- Programme:
- Communication initialisation cycle.
- Device status readout.
- Sending control commands (e.g. changing engine speed).
4. communication testing
4.1 Verification of connection
- In TIA Portal, open the tool Online & Diagnostics.
- Check the status of the Profinet connection between the PLC and INVEOR DAXI.
4.2 Functional test
- Run the control programme on the PLC.
- Verify the operation of the control functions (e.g. motor start/stop, parameter reading).
Common problems and solutions
Problem: No communication between devices
Solution: Check the IP addresses and Profinet network configuration on both devices.
Problem: Incorrect process data
Solution: Verify the mapping of inputs and outputs in TIA Portal.
Problem: INVEOR DAXI controller does not respond to commands
Solution: Ensure that the communication protocol on both devices is correctly configured.
Summary
Correct configuration of the INVEOR DAXI controller with Siemens S7-300, S7-1200 and S7-1500 PLCs requires careful adherence to the following steps, from preparing the hardware to testing the communication. By following these instructions, we can ensure that these devices work effectively together in industrial automation systems.
