UNITRONICS Vision OPLC PLC Controller User Guide

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 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.

Removable Memory Storage

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.

Additional product documentation is in the Technical Library, located at www.unitronicsplc.com.

Danger Symbols

When any of the following symbols appear, read the associated information carefully.

Environmental Considerations

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.

Mounting

Dimensions

Note that the LCD screen may have a single pixel that is permanently either black or white.

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

Wiring

Wiring Proced
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 requires either an external 12 or 24VDC power supply. Permissible input voltage range: 10.2-28.8VDC, with less than 10% ripple.

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.
▪ 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).

*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.

*Default factory setting
**Causes the unit to function as an end unit in an RS485 network

Removing a Snap -in I/O Module

1. Locate the four screws 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.

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.

CANbus
These controllers comprise a CANbus port. Use this to create a decentralized control network using one of the following CAN protocols:

• CANopen: 127 controllers or external devices
• CANLayer 2
• Unitronics’ proprietary UniCAN: 60 controllers, (512 data bytes per scan)
  The CANbus port is galvanically isolated.

CANbus Wiring

Use twisted-pair cable. DeviceNet® thick shielded twisted pair cable is recommended.
Network terminators: These are supplied with the controller. Place terminators at each end of the CANbus network.
Resistance must be set to 1%, 121Ω, 1/4W.
Connect ground signal to the earth at only one point, near the power supply.

The network power supply need not be at the end of the network.

CANbus Connector
