3. Status indicator lights (LEDs)
The front panel provides clear operational status indicators:
3.3 V: The internal voltage supply of the controller is normal.
RUN: The controller has been initialized and is in the 'running' state. Flashing indicates that it has not been initialized.
BUS: The fieldbus communication is normal.
For PROFINET RT/EtherNet/IP models, additional services are provided:
NS (Network Status): Indicates IP address allocation and connection status.
MS (HACD status): Indicates high availability consistency domain status.
L (Link): Indicates the active connection with the communication partner.
S (transmission status): Flashing indicates sending/receiving Ethernet messages.

System Integration and Interface Detailed Explanation
1. Mechanical installation
VT-HNC100... 3X is designed for installation on top cap rails (DIN rails) inside control cabinets. By inserting the controller casing into the conductive mounting rail, a ground connection can be established with the control cabinet backplane to achieve high-frequency (HF) grounding.
Installation environment: It must meet the environmental conditions specified in data manual RE 30139, avoid conductive pollutants (acid, alkali, salt, metal vapor, etc.), and ensure compliance with IP20 protection level.
Attention: The equipment casing has perforations. During installation and operation, it is necessary to ensure a clean environment to prevent liquids and dirt from entering and causing short circuits.
2. Electrical wiring and EMC specifications
Correct wiring is crucial for system stability and anti-interference:
Power supply: Try to shorten the power line (+24V/GND) as much as possible and ensure that the power supply and return lines are wired in parallel.
Shielding: Signal lines must use cables with copper braided mesh shielding. The cable shielding layer should be connected extensively on the VT-HNC100 side through a connector metal shell or shielding pin, and crimped with a tensioning device. The shielding layer is only grounded at the controller end.
Wiring principle:
Try to arrange the signal line and load line separately as much as possible to avoid parallel wiring.
Signal lines should avoid passing through areas with strong magnetic fields.
Try to lay signal lines continuously. If intermediate wiring is required, terminal blocks with shielding strips must be used.
For multi axis versions of analog/digital interfaces, it is recommended to use pre assembled distribution cables (such as material number R901189300/R901189302) with a maximum length of 2 meters.
External component power supply: When supplying power to external components such as encoders or pressure sensors, it is necessary to ensure that the input voltage of X1S meets the specifications of these components (such as 24V ± 5%, ripple<500mV).
3. Bus address and network settings
Address switch: located on the front panel of the controller, used to set the node address of PROFIBUS DP or CANopen (1-127 binary settings). Position '0' is the boot mode used for data transmission.
PROFINET RT/EtherNet/IP: IP address via WIN-PED ® 7 software allocation, the front panel address switch is invalid in this mode.
PROFIBUS DP with TCP/IP: also via WIN-PED ® 7. Assign IP addresses to software.
Installation, debugging, and software configuration
1. Preparation before debugging
Essential tools: VT-HNC100... 3X controller, 24V power supply PC。
Essential software and connections:
WIN-PED ® 6 or 7 software: can be downloaded for free from the Bosch Rexroth official website.
Connection cable: RS232 interface cable (such as R900776897) or USB to RS232 converter (such as R901066684). For Ethernet models, TCP/IP network connections can also be used.
First power on inspection: Carefully check all wiring to ensure there are no errors before connecting 24V operating voltage. The controller needs to adapt to the ambient temperature for several hours to prevent condensation from forming inside the casing.
2. WIN-PED ® Software core functions
WIN-PED ® It is a dedicated PC software for VT-HNC100... 3X programming, setting, and diagnosis, providing the following core functions:
Machine Data Settings: A convenient dialog box for setting machine parameters online or offline.
NC Editor: Integrated syntax check and program compiler.
Parameter management: supports parameter definition and online value setting used in NC programs.
Process monitoring: Display the status of digital I/O and flag bits in multiple ways; Up to 16 process parameters can be recorded and graphically displayed.
Special function graphical definition: for example, defining functions through trajectories.
Bus Manager: Configure data exchange with higher-level control systems (PROFIBUS DP, PROFINET RT, or CANopen).
3. First debugging process
Physical connection: Connect the controller to the PC via RS232 cable or Ethernet cable.
Software startup: Install and start WIN-PED on PC ® And corresponding control type software.
Establish communication: in WIN-PED ® Select the correct port and protocol (such as COM port, TCP/IP address) from the "Communication" menu to establish an online connection with the controller.
