ModbusTCP network. Install the file in the engineering tool so that the PN/ModbusTCP Coupler is available The PN/ModbusTCP Coupler must be supplied with 24 V DC at the wide range input for configuration. 18 ... 30 V via the provided connector. The power supply is designed redundantly. At least a supply path PS 1 or PS 2 must be connected.
6. Concept of data exchange The PN/ModbusTCP Coupler is a ModbusTCP server. It receives data via ModbusTCP, which is then transmitted to the IO image of the PROFINET PLC (inputs in the PLC) and makes data available as transmission data, which it receives from the PROFINET PLC (outputs in the PLC).
7. Supported ModbusTCP function codes The PN/ModbusTCP Coupler supports the following function codes: Data size Data range Function Function code Function code decimal Input bits Read discrete inputs 0x02 Read coils 0x01 Output bits or Bit access Write single coil...
8. Configuration in the TIA portal The PN/ModbusTCP Coupler can be found in the hardware catalog under “Other field devices / PROFINET IO / Gateway / Helmholz GmbH & Co. KG / Helmholz PN/Mod- busTCP Coupler”. The PN/ModbusTCP Coupler can be completely configured via the GSDML file in the PROFINET configurator.
9. Parameters of the PN/ModbusTCP Coupler The configuration of the PN/ModbusTCP Coupler can take place completely through the PROFINET hardware configurator. However, several parameters can also be optionally set via the website, e.g. the IP address of the ModbusTCP server, the DHCP host name.
When the configuration of the PN/ModbusTCP Coupler has been completed in the hardware configurator of the engineering tool, it can be loaded into the PLC. In order that the PN/ModbusTCP Coupler can be found by the PROFINET controller, the PROFINET device name must be assigned to the PN/ModbusTCP Coupler. To this purpose, use the function “Assign device name”, which you can access in the Online...
11. Web interface of the PN/ModbusTCP Coupler The web interface of the PN/ModbusTCP coupler provides an overview of the status and the configuration of the device, as well as the possibility for carrying out a firm- ware update. The ModbusTCP configuration can also be set in the web interface if this hasn’t been prescribed through the PROFINET configuration.
