I/Os via:

I/O Expansion Modules

Local or remote I/Os may be added

via expansion port or CANbus.

Information Mode This mode enables you to:

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 <i> button for several seconds.

Programming

Software,

&Utilities

The Unitronics Setup CD contains VisiLogic software and other utilities.

VisiLogic

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

Includes 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.

Removable

Memory Storage

Micro SD card: store datalogs, Alarms, Trends, Data Tables; export to Excel;

backup Ladder, HMI & OS and use this data to ‘clone’ PLCs.

For more data, refer to the SD topics in the VisiLogic Help system.

Data Tables Data tables enable you to set recipe parameters and create datalogs.

Before using this product, the user must read and understand this document.

All examples and diagrams are intended to aid understanding, and do not guarantee operation.

Unitronics accepts no responsibility for actual use of this product based on these examples.

Please dispose of this product according to local and national standards and regulations.

Only qualified service personnel should open this device or carry out repairs.

Failure to comply with appropriate safety guidelines can cause severe injury or property damage.

Do not attempt to use this device with parameters that exceed permissible levels.

To avoid damaging the system, do not connect/disconnect the device when power is on.

Environmental Considerations

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, in accordance

with the standards given in the product’s technical specification sheet.

Ventilation: 10mm space required between controller’s top/bottom edges & enclosure walls.

Mounting

Dimensions

Panel Mounting

Before you begin, note that the mounting

panel cannot be more than 5 mm thick.

1. Make a panel cut-out measuring

92x92 mm (3.622”x3.622”).

2. Slide the controller into the cut-out,

ensuring that the rubber seal is in place.

3. Push the 2 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 in the figure to the right.

DIN-rail Mounting

1. Snap the controller onto the DIN

rail as shown in the figure to the

right.

2. When properly mounted, the

controller is squarely situated on

the DIN-rail as shown in the figure

to the right.

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.

Caution

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 s

tripped wire that might cause the wire 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.

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 used over an extended distance. Use

wire that is properly sized for the load.

The controller and I/O signals must be connected to the same 0V signal.

Vision™ OPLC™

Unitronics 5

Power Supply

The controller requires an external 12VDC or 24VDC power supply.

Anon-isolated power supply can be used if a 0V signal is connected to the chassis.

Install an external circuit breaker. Guard against short-

circuiting in external wiring.

Double-check all wiring before turning on the

power supply.

Do not connect either the ‘Neutral or ‘Line’ signal of the

110/220VAC to device’s 0V pin.

In the event of voltage fluctuations or non-conformity to

voltage power supply specifications, connect the device

to a regulated power supply.

Earthing the Power Supply

To maximize system performance, avoid electromagnetic interference by:

Mounting the controller on a metal panel.

Earthing the controller’s power supply: connect one end of a 14 AWG wire to the chassis

signal; connect the other end to the panel.

Note: If possible, the wire used to earth the power supply should not exceed 10 cm in length.

However, it is recommended to earth the controller in all cases.

Communication Port

Turn off power before making communications connections.

Caution

Signals are related to the controller’s 0V; the same 0V is used by the power supply.

Always use the appropriate port adapters.

The serial port is not isolated. If the controller is used with a non-isolated external

device, avoid potential voltage that exceeds ± 10V.

Port 1 is type RJ-11 and may be set to either RS232 or RS485 via jumper as shown below.

By factory default, the port is set to RS232, termination ON.

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 the 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 (+)

20V reference 2 (RS232 signal)

3TXD signal 3 (RS232 signal)

4RXD signal 4 (RS232 signal)

50V reference 5 (RS232 signal)

6* DSR signal 6 B signal (-)

Pin #1

*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 Jumper Settings

The figure to the right shows the jumper

factory default settings, RS232, RS485

termination ON.

Note that in order:

To change the communication

setting to RS485, both

communication standard

jumpers must be moved.

To change the RS485

termination, both termination

jumpers must be moved.

To access the jumpers, you must open the

controller according to the instructions

beginning on page 7.

Opening the Controller

Before performing these actions, touch a grounded object to discharge any electrostatic

charge.

Avoid touching the PCB board directly. Hold the PCB board by its connectors.

1. Turn off the power supply, disconnect, and dismount the controller.

2. The back cover of the controller comprises 4 screws, located in the corners. Remove the screws,

and pull off the back cover.

Changing Communication Settings

1. To access the communication

jumpers, hold the Power Supply

PCB by its edges and steadily pull

the board off.

2. Locate the jumpers, and then

change the settings as required.

Jumper settings are shown on

page 6.

Closing the Controller

1. Gently replace the board. Make

certain that the pins fit correctly

into their matching receptacle.

Do not force the board into place;

doing so may damage the

controller.

2. Replace the back cover of the

controller and fasten the corner

screws.

Note: You must replace the back cover securely before powering up the controller.
