Siemens TIA Portal V14 gateway mapping example
Below is a screenshot from TIA Portal V14 showing how the gateway can be mapped into the system. Use the GSDML file
that is downloadable from the Hilscher website to add support for the Hilscher NT 50-RS-EN gateway into your system.
Basic operation for Modbus RTU
The motor drive must be in ON-state before the tool can be started. The very first command that should be sent to the
motor drive is the ON-state command. It is not mandatory to send the OFF-state command before removing power from
the motor drive.
When the motor drive is in ON-state the speed set-point value can be written and the state can be set to RUN-state by
sending the RUN-state command. This will cause the tool to run at the set-point speed. To stop the tool, set the motor
drive to STOP-state by sending the STOP-state command.
It is recommended to continuously monitor the average speed, average current, tool temperature, motor drive temperature
and the alarm status flag. This will help to detect if there are any issues present during operation.
Example sequence for starting and stopping the tool:
• Write 4 (0x0004) to the "Operation" register, this will set the motor drive to ON-state.
