The Unitronics V570-57-T40B, V570-57-T20B, and V570-57-T20B-J are programmable logic controllers (PLCs) that integrate a built-in operating panel with a 5.7-inch color touchscreen. This touchscreen displays a virtual keyboard for operator data entry when required by the application.

Function Description:

These OPLCs are designed for industrial control applications, combining the functionality of a PLC with a human-machine interface (HMI). They support various communication protocols and I/O options, making them versatile for different automation tasks. The controllers can be programmed to manage complex processes, display real-time data, and allow operator interaction through the touchscreen.

Important Technical Specifications:

Display: 5.7" Color Touchscreen with virtual keyboard.
Communication Ports:
- Two isolated RS232/RS485 ports. These ports are RJ-11 type and can be configured for either RS232 or RS485 via DIP switches. RS232 is used for program downloads from a PC and communication with serial devices (e.g., SCADA). RS485 supports multi-drop networks with up to 32 devices.
- One isolated CANbus port. This port can be used to create a decentralized control network using CANopen (up to 127 controllers/external devices), CANLayer 2, or Unitronics' proprietary UniCAN (up to 60 controllers with 512 data bytes per scan).
- Optional Ethernet port (user-orderable and installable).
Communication Function Blocks: Include SMS, GPRS, and MODBUS serial/IP Protocol FBs, enabling communication with almost any external device via serial or Ethernet.
I/O Options:
- Snap-in I/O Modules: Plug into the back of the controller for on-board I/O configuration (digital, high-speed, analog, weight, temperature measurement).
- I/O Expansion Modules: Local or remote I/Os can be added via an expansion port or CANbus.
Power Supply:
- V570-57-T20B & V570-57-T20B-J: Requires an external 12 or 24VDC power supply. Permissible input voltage range: 10.2-28.8VDC (less than 10% ripple).
- V570-57-T40B: Requires an external 24VDC power supply. Permissible input voltage range: 20.4-28.8VDC (less than 10% ripple).
- A non-isolated power supply can be used if a 0V signal is connected to the chassis.
Removable Memory Storage: Supports SD cards for storing datalogs, alarms, trends, data tables, exporting to Excel, backing up Ladder, HMI & OS, and 'cloning' PLCs.
Data Tables: Enable setting recipe parameters and creating datalogs.

Usage Features:

Programming: The Unitronics Setup CD includes VisiLogic software, which allows users to easily configure hardware and write both HMI and Ladder control applications. The Function Block library simplifies complex tasks like PID. Applications are downloaded to the controller via a programming cable.
Utilities: The software package includes UniOPC server, Remote Access for remote programming and diagnostics, and DataXport for run-time data logging.
Information Mode: Accessible by pressing the <i> button for several seconds, this mode allows users to:
- Calibrate the touchscreen.
- View and edit operand values, COM port settings, RTC, and screen contrast/brightness settings.
- Stop, initialize, and reset the PLC.
Battery Insertion: A battery is supplied (not installed) to preserve data in case of power-off. It must be inserted into the battery holder on the rear of the controller, ensuring correct polarity.
Mounting: The controller is designed for panel mounting. A panel cut-out must be made according to specified dimensions (146.6 mm x 124.5 mm for the opening, 197 mm x 146.6 mm overall). The controller slides into the cut-out with a rubber seal, and four mounting brackets secure it to the panel. The mounting panel cannot be more than 5 mm thick.
Wiring:
- Crimp terminals are recommended for wiring, using 26-12 AWG wire (0.13 mm²–3.31 mm²).
- Wires should be stripped to 7±0.5mm (0.250–0.300 inches) and inserted completely into the terminal, then tightened.
- External circuit breakers and appropriate circuit protection devices must be installed.
- Double-check all wiring before powering on.
- Avoid connecting unused pins.
- Do not exceed a maximum torque of 0.5 N·m (5 kgf·cm) when tightening wires.
- Do not use tin, solder, or any substance on stripped wire.
- Install at maximum distance from high-voltage cables and power equipment.
Earthing: To maximize system performance and avoid electromagnetic interference, the controller should be mounted on a metal panel, and its power supply should be earthed. A 14 AWG wire, ideally not exceeding 10 cm, should connect the chassis signal to the panel.
CANbus Wiring: Use twisted-pair cable (DeviceNet® thick shielded twisted pair cable is recommended). Network terminators (121Ω, 1/4W) must be placed at each end of the CANbus network. The ground signal should be connected to earth at only one point, near the power supply.

Maintenance Features:

Snap-in I/O Module Removal/Re-installation: Modules can be removed by pressing four buttons on the sides of the controller and gently rocking the module. Re-installation involves aligning circular guidelines and applying even pressure until a 'click' is heard.
Environmental Considerations:
- Avoid installation in areas with excessive or conductive dust, corrosive or flammable gas, moisture, rain, excessive heat, regular impact shocks, or excessive vibration.
- Ensure 10mm ventilation space between the controller's top/bottom edges and enclosure walls.
- Do not expose the unit to water or allow debris to fall inside during installation.
Safety Guidelines:
- Always turn off power before making communication connections or wiring.
- Do not touch live wires.
- Do not connect/disconnect the device when power is on to avoid damage.
- Do not use parameters that exceed permissible levels.
- Only qualified service personnel should open the device or carry out repairs.
- Dispose of the product according to local and national standards.
LCD Screen: Note that the LCD screen may have a single pixel that is permanently either black or white.
