Information Mode

This mode enables you to:

▪View & Edit operand values, COM port settings, RTC and screen

contrast/brightness settings

▪Calibrate the touchscreen

▪Stop, initialize, and reset the PLC

To enter Information Mode, press the <i> button for several seconds.

Programming

Software,

& 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.

Note that in order to program the V290-19-B20B,you must select the

V280/V530 in VisiLogic's Hardware Configuration.

▪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.

Mounting

Before you begin, note that:

▪The mounting panel cannot be more than 5 mm thick

▪To minimize electromagnetic interference, mount the controller on a metal panel and

earth the power supply according to the details on page 6.

1. Make a panel cut-out that suits your model controller.

Caution

▪The necessary torque is 0.45 N·m (4.5 kgf·cm).

V230/280/290

Unitronics

2. If you mount the controller on a metal panel, earth the power supply only in

V230:

a. Bore a hole to suit the NC6-32 screw supplied with the kit.

b. Scrape panel paint away from the contact area to ensure a conductive connection.

c. Drive the screw into the hole.

d. Place the following hardware screw’s shank, in the order shown in the

accompanying figure: washer, ring cable shoe, second washer, spring, and nut.

▪Pay Attention:

The wire used to earth the power supply must not exceed 10 cm in length

if your conditions do not permit this, do not earth the power supply.

▪Make sure that the metal panel is properly earthed.

3. Slide the controller into the cut-out, ensuring

that the rubber seal is in place.

4. Push the 4 mounting brackets into their slots

on the sides of the controller as shown in the

figure to the right.

5. Tighten the bracket screws against the

panel. Hold the bracket securely against the

unit while tightening the screw.

6. When properly mounted, the controller is squarely situated in the panel cut-out as shown below.

Wiring: General

▪This equipment is designed to operate only in SELV/PELV/Class 2/Limited Power

environments

▪All power supplies in the system must include double insulation. Power supply 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.

▪Do not touch live wires.

▪All wiring activities should be performed while power is OFF.

▪Unused pins should not be connected. Ignoring this directive may damage the device

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 stripped wire that might cause the wire

strand to break

Use crimp terminals for wiring; use 26-14 AWG wire (0.13 mm 2–2.08 mm2).

User Guide

Unitronics

1. Strip the wire to a length of 7±0.5mm (0.250–0.300”).

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.

Wiring Guidelines

▪Use separate wiring ducts for each of the following groups:

▪Group 1: Low voltage I/O and supply lines, communication lines.

▪Group 2: High voltage Lines, Low voltage noisy lines like motor driver outputs.

Separate these groups by at least 10cm (4"). If this is not possible, cross the ducts at a 90˚angle.

▪For proper system operation, all 0V points in the system should be connected to the

system 0V supply rail.

Earthing the Controller

To maximize system performance, avoid electromagnetic interference as follows:

▪Use a metal cabinet.

▪Connect the 0V terminal to the earth ground of the system at one point, preferably as near to the

controller as possible.

Power Supply

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

range is 10.2-28.8VDC, with less than 10% ripple.

▪You must use an external circuit protection device

▪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

V230/280/290

Unitronics

Communication Ports

▪Turn off power before making communications connections

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

Caution

▪Always use the appropriate port adapters

▪The serial ports are not isolated. If the controller is used with a non-isolated external

device, avoid potential voltage that exceeds ± 10V

Serial Communications

This series comprises 2 RJ-11-type serial ports and a CANbus port.

COM1 is RS232 only. COM2 may be set to either RS232 or RS485 via jumper as described below.

By default, the port is set to RS232.

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.

Caution

▪COM1 & 2 are not isolated

Pinouts

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).

*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 Jumper Settings

The port is 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

jumpers according to the following table.

Note:

For V230/V280/V290 modules only there is a small window as described on page 6 for

jumper setting so there is no need to open the controller.

▪Before you begin, touch a grounded object to discharge any electrostatic charge

1. Before removing a Snap-in I/O Module or opening the controller, you must turn off the power
