Communications
 2 serial ports: RS232 (COM1), RS232/RS485 (COM2)
 1 CANbus port
 The user can order and install an additional port. Available port
types are: RS232/RS485, and Ethernet
 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
Vision 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
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.

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
6

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
Unitronics
Installation Guide
Use crimp terminals for wiring; use 26-14 AWG wire (0.13 mm 2–2.08 mm2).
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 shortcircuiting 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


Communication Ports



Caution 
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
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).

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

Installation Guide
Removing a Snap-in I/O Module
1. Locate the four buttons on the sides of the module, 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.
Re-installing a Snap-in I/O Module
1. Line the circular guidelines on the controller up with the guidelines on the Snap-in I/O Module as
shown below.
2 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.
