The Unitronics V350-35-TR34 is a micro-OPLC (Operator Panel Logic Controller), a rugged programmable logic controller that integrates an on-board I/O configuration with a built-in operating panel. This operating panel features a 3.5-inch color touchscreen and programmable function keys, providing a comprehensive solution for control and human-machine interface (HMI) applications.

Function Description:

The V350-35-TR34 is designed to manage a variety of control tasks through its versatile I/O capabilities and communication options. It supports digital, high-speed, analog, weight, and temperature measurement I/Os. The device can be expanded with additional local or remote I/O modules via an expansion port or CANbus, offering flexibility for various application sizes and complexities.

I/O Configuration:

The controller includes:

• 22 Digital Inputs: These inputs are highly configurable. They can be wired as a group and set to either NPN (sink) or PNP (source) via a single jumper.
  • Inputs 14 and 15 can function as either digital or analog inputs.
  • Inputs 0, 2, and 4 can function as high-speed counters, as part of a shaft-encoder, or as normal digital inputs.
  • Inputs 1, 3, and 5 can function as either counter reset, as part of a shaft-encoder, or as normal digital inputs.
  • If inputs 0, 2, and 4 are set as high-speed counters (without reset), inputs 1, 3, and 5 can function as normal digital inputs.
• 8 Relay Outputs: These outputs provide switching capabilities for various loads.
• 4 High-Speed NPN Transistor Outputs: These outputs are suitable for applications requiring faster switching speeds.

Communication:

The V350-35-TR34 offers robust communication features:

• Built-in Serial Port: One RS232/RS485 serial port is integrated.
• Optional Modules: Users can order and install one or both of the following modules:
  • RS232/RS485/Ethernet module for enhanced connectivity.
  • CANbus module for industrial network communication.
• Communication Function Blocks: The device supports various communication protocols including SMS, GPRS, MODBUS (serial/IP). A Protocol Function Block allows the PLC to communicate with almost any external device via serial or Ethernet.
• RS232/RS485 Jumper Settings: The serial port can be configured for either RS232 or RS485 via jumpers. By default, the port is set to RS232 with termination ON. RS232 is used for program downloads from a PC and communication with serial devices like SCADA. RS485 enables the creation of a multi-drop network with up to 32 devices.

Usage Features:

• Operating Panel: The integrated 3.5" Color Touchscreen and programmable function keys provide a user-friendly interface for monitoring and control.
• Information Mode: This mode allows users to:
  • View and edit operand values.
  • Configure COM port settings.
  • Adjust Real-Time Clock (RTC) and screen contrast/brightness settings.
  • Calibrate the touchscreen.
  • Stop, initialize, and reset the PLC.
  • Information Mode is accessed by pressing the <i> button for several seconds.
• Removable Memory Storage (Micro SD card): This feature allows for:
  • Storing datalogs, alarms, trends, and data tables.
  • Exporting data to Excel.
  • Backing up Ladder logic, HMI, and OS.
  • Cloning PLCs.
• Data Tables: Enable setting recipe parameters and creating datalogs.
• Programming Software (VisiLogic): The Unitronics Setup CD includes VisiLogic software, which allows users to:
  • Easily configure hardware.
  • Write both HMI and Ladder control applications.
  • Utilize a Function Block library for complex tasks like PID.
  • Download applications to the controller via the included programming cable.
• Utilities: The Setup CD also includes:
  • UniOPC server.
  • Remote Access for remote programming and diagnostics.
  • DataXport for run-time data logging.
• Mounting: The controller supports both panel mounting and DIN-rail mounting.
  • Panel Mounting: Requires a panel cut-out of 92 x 92 mm (3.622" x 3.622"). The mounting panel thickness should not exceed 5 mm. The controller slides into the cut-out with a rubber seal, secured by two mounting brackets.
  • DIN-rail Mounting: The controller snaps onto a standard DIN rail.

Maintenance Features:

• Increasing Contact Life Span: To extend the life of relay output contacts and protect against reverse EMF, it is recommended to connect a clamping diode in parallel with each inductive DC load and an RC snubber circuit in parallel with each inductive AC load.
• Opening the Controller: For accessing I/O jumpers or communication jumpers, the controller can be opened by removing four screws on the back cover.
  • Safety Precaution: Before opening, discharge any electrostatic charge by touching a grounded object. Avoid touching the PCB board directly; hold it by its connectors.
  • Procedure: Turn off power, disconnect, and dismount the controller. Remove the four corner screws from the back cover and pull it off.
• Changing I/O Settings: Once the controller is open, the I/O board is exposed, allowing changes to I/O settings according to the jumper configurations detailed in the manual.
• Changing Communication Settings: To access communication jumpers, the I/O PCB board needs to be steadily pulled off by its top and bottom connectors. Jumpers can then be changed as required.
• Closing the Controller: Gently replace the board, ensuring pins fit correctly. Do not force the board. Replace the back cover and fasten the corner screws. The back cover must be securely replaced before powering up the controller.

Important Technical Specifications and Environmental Considerations:

• Wiring:
  • Use crimp terminals for wiring with 26-12 AWG wire (0.13 mm²–3.31 mm²).
  • Strip wire to 7±0.5mm (0.250–0.300 inches).
  • Do not exceed a maximum torque of 0.5 N·m (5 kgf·cm) when tightening terminals to avoid wire damage.
  • Do not use tin, solder, or any substance on stripped wire that might cause the wire strand to break.
  • Input or output cables should not be run through the same multi-core cable or share the same wire.
  • Allow for voltage drop and noise interference with input lines over extended distances.
  • The controller and I/O signals must be connected to the same 0V signal.
• Power Supply:
  • Install an external circuit breaker and use appropriate circuit protection devices.
  • Double-check all wiring before turning on the power supply.
  • A non-isolated power supply can be used if a 0V signal is connected to the chassis.
  • Do not connect the ‘Neutral’ or ‘Line’ signal of 110/220VAC to the device’s 0V pin.
  • In case of voltage fluctuations or non-conformity to power supply specifications, connect the device to a regulated power supply.
  • Earthing: Mount the controller on a metal panel. Connect one end of a 14 AWG wire to the chassis signal and the other end to the panel. The earthing wire should ideally not exceed 10 cm.
• Environmental Conditions:
  • Do not install in areas with excessive or conductive dust, corrosive or flammable gas, moisture or rain, excessive heat, regular impact shocks, or excessive vibration, as specified in the product's technical specification sheet.
  • Ensure 10mm space between the controller's top/bottom edges and enclosure walls for ventilation.
  • Do not place in water or allow water to leak onto the unit.
  • Prevent debris from falling inside the unit during installation.
  • Install at maximum distance from high-voltage cables and power equipment.
• Safety Guidelines:
  • Do not touch live wires.
  • Unused pins should not be connected, as this may damage the device.
  • Only qualified service personnel should open this device or carry out repairs.
  • Do not attempt to use this device with parameters exceeding permissible levels.
  • Do not connect/disconnect the device when power is on to avoid damaging the system.
  • The serial port is not isolated. If used with a non-isolated external device, avoid potential voltage exceeding ±10V.
