Vision™ OPLC™ Installation Guide

V1040-T20B

This guide provides basic information for Unitronics’ controllers V1040-T20B.

General Description

V1040 OPLCs are programmable logic controllers that comprise a built-in operating panel containing
a 10.4” Color Touchscreen. The V1040 offers function keys along with a virtual alpha-numeric
keyboard which is automatically displayed when the application requires the operator to enter data.

Communications  2 isolated RS232/RS485 ports

 USB programming port (Mini-B)
 Isolated CANbus port
 The user can order and install an additional port. This may be
either Ethernet or serial.
 Communication Function Blocks include: SMS, GPRS, MODBUS
serial/IP; Protocol FB enables PLC to communicate with almost
any external device, via serial or Ethernet communications
I/O Options V1040 supports digital, high-speed,
analog, weight and temperature
measurement I/Os via:
 Snap-in I/O Modules
Plug into the back of the
controller to provide an on-
board I/O configuration
 I/O Expansion Modules
Local or remote I/Os may be
added via expansion port or
CANbus.
Installation instructions and other data may be found in the module’s technical
specification sheet.
Information Mode This mode enables you to:
 Calibrate the touchscreen
 View & Edit operand values, COM port settings, RTC and screen
contrast/brightness settings
 Stop, initialize, and reset the PLC
To enter Information Mode, press the touchscreen and maintain contact for
several seconds.

Programming The Unitronics Setup CD contains VisiLogic software and other utilities
Software,  VisiLogic
& Utilities Easily configure hardware and write both HMI and Ladder control
applications; the Function Block library simplifies complex tasks
such as PID. Write your application, and then download it to the
controller via the programming cable included in the kit.
 Utilities
These include UniOPC server, Remote Access for remote
programming and diagnostics, and DataXport for run-time data
logging.
To learn how to use and program the controller, as well as use utilities such as
Remote Access, refer to the VisiLogic Help system.

Inserting the Battery

In order to preserve data in case of power-off, you must insert the battery.
The battery is supplied taped to the battery cover on the rear of the controller.
1. Remove the battery cover shown on page 4. The polarity (+) is marked on the battery holder and
on the battery.
2. Insert the battery, ensuring that the polarity symbol on the battery is:
- facing up
- aligned with the symbol on the holder
3. Replace the battery cover.

Panel Mounting
Before you begin, note that the mounting panel cannot be more than 5 mm thick.

1. Make a panel cut-out according to

the dimensions in the figure to the
right.

2. Slide the controller into the cut-

out, ensuring that the rubber seal
is in place.

3. Push the 8 mounting brackets into

their slots on the sides of the
controller as shown in the figure to
the right.

4. Tighten the bracket screws

against the panel. Hold the
bracket securely against the unit
while tightening the screw.

5. When properly mounted, the

controller is squarely situated in
the panel cut-out as shown below.

Wiring
 Do not touch live wires.
 Install an external circuit breaker. Guard against short-circuiting in external wiring.
 Use appropriate circuit protection devices.
 Unused pins should not be connected. Ignoring this directive may damage the device.
 Double-check all wiring before turning on the power supply.
 To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m (5 kgf·cm).
 Do not use tin, solder, or any substance on stripped wire that might cause the wire
Caution
strand to break.
 Install at maximum distance from high-voltage cables and power equipment.

Wiring Procedure
Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm 2–3.31 mm2).
1. Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).
2. Unscrew the terminal to its widest position before inserting a wire.
3. Insert the wire completely into the terminal to ensure a proper connection.
4. Tighten enough to keep the wire from pulling free.

Power Supply
The controller V1040-T20B requires either an external 12 or 24VDC power supply.
Permissible input voltage range: 10.2-28.8VDC, with less than 10% ripple.
 The power supply must include double insulation. Outputs must be rated as
SELV/PELV/Class 2/Limited Power.
 Do not connect either the ‘Neutral or ‘Line’ signal of the 110/220VAC to device’s 0V pin.
 Install an external circuit breaker. Guard against short-
circuiting in external wiring.
 Double-check all wiring before turning on the power
supply.
 In the event of voltage fluctuations or non-conformity to
voltage power supply specifications, connect the device
to a regulated power supply.

Earthing the OPLC

To maximize system performance, avoid electromagnetic interference by:
 Mounting the controller on a metal panel.
 Connect the functional earth terminal of the OPLC, and the common and ground lines of
I/Os, directly to the earth ground of your system.
 For ground wiring, use the shortest and thickest possible wire.

Communication Ports
This series comprises a USB port, 2 RS232/RS485 serial ports and a CANbus port. An additional
port may be ordered separately and installed. This port may be either Ethernet, or serial (COM 3).
For the most updated information regarding ports and their installation, please refer to the Technical
Library at www.unitronics.com.
 Turn off power before making communications connections.

Caution  Always use the appropriate port adapters.

The USB port may be used for programming, OS download, and PC access.
Note that COM port 1 function is suspended when this port is physically connected to a PC.
The serial ports are type RJ-11 and may be set to either RS232 or RS485 via DIP switches, in
accordance with the table shown below.
Use RS232 to download programs from a PC, and to communicate with serial devices and
applications, such as SCADA.
Use RS485 to create a multi-drop network containing up to 32 devices.

Pinouts
The pinouts below show PLC port signals.
To connect a PC to a port that is set to RS485, remove the RS485 connector, and connect the PC to
the PLC via the programming cable. Note that this is possible only if flow control signals are not used
(which is the standard case).
RS232 RS485** Controller Port
Pin # Description Pin # Description
1* DTR signal 1 A signal (+)
2 0V reference 2 (RS232 signal)
3 TXD signal 3 (RS232 signal)
4 RXD signal 4 (RS232 signal) Pin #1
5 0V reference 5 (RS232 signal)
6* DSR signal 6 B signal (-)
*Standard programming cables do not provide connection points for pins 1 and 6.
**When a port is adapted to RS485, Pin 1 (DTR) is used for signal A,
and Pin 6 (DSR) signal is used for signal B.
RS232 to RS485: Changing DIP Switch Settings
The ports are set to RS232 by factory default.
To change the settings, first remove the Snap-in I/O Module, if one is installed, and then set the
switches according to the following table.

RS232/RS485: DIP Switch Settings

The settings below are for each COM port.

Installing a Snap-in I/O Module

 Before installing a Snap-In Module, ensure that the Communication Module Cover is
closed.

1. Remove the I/O connector cap shown on Page 4.

2. Line the circular guidelines on the Snap-in I/O Module with the slots on the controller as shown
below.
3 Apply even pressure on all 4 corners until you hear a distinct ‘click’. The module is now installed.
Check that all sides and corners are correctly aligned.

Removing a Snap-in I/O Module

1. Locate the four buttons on the sides of the controller, two on either side.
2. Press the buttons and hold them down to open the locking mechanism.
3. Gently rock the module from side to side, easing the module from the controller.
