V350-35-TR20 
Installation Guide  

The Unitronics V350-35-TR20 offers the following onboard I/Os: 

  12 Digital Inputs, configurable via wiring to include 2 Analog, and 3 HSC/Shaft-encoder Inputs   

  6 Relay Outputs 

  2 high-speed npn Transistor Outputs 

General Description 

V350 OPLCs are micro-OPLCs, rugged programmable logic controllers that comprise:  

  On-board I/O configuration 

  Built-

in operating panel containing a 3.5” Color Touchscreen and programmable function keys 

Communications 

  1 built-in serial port: RS232/RS485 

  Optional: the user may order and 

install one or both of the following 
modules:  
- RS232/RS485/Ethernet  
- CANbus 

  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 

V350 supports digital, high-speed, analog, 
weight and temperature measurement I/Os via: 

  On-board I/O configuration  

Model-dependent 

  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.
