Welcome to Remote Access
Remote Access enables you to use a PC to access a remote controller. During a Remote
Access session, the remote controller is displayed, on-line, on your PC screen. You can ‘press’
keypad keys and touch-screen objects, check system status and run-time values, as well as
test and troubleshoot problems in remote controllers and applications. You can access:
Stand-alone controllers that are directly connected to the PC via a cable.
Controllers within a network.
Either stand-alone or networked controllers via GSM or landline modem.
Devices with IP addresses, via Ethernet.
Remote Access can be used with either Vision or M90/91 controllers. Vision controllers require
O/S versions 2.96 and higher; M90/91 require V3.00 and higher.
Using Remote Access
The Remote Access package includes additional utilities:

Note The PC-modem cable is not the same type of cable used to connect between the
controller and the modem. Ensure that the cable used to connect the PC to the modem
provides connection points for all of the modem's pins.
Both PC and controller must use the same type of modem: either landline or GSM.
Internal modems must be used in conjunction with the driver provided by the modem's
manufacturer.
If call are routed via a switchboard, note that the switchboard settings may interfere with
communications. Consult with your switchboard provider.

Operand Access is located on the Tools menu. This utility enables you to access operands in a
local or remote controller and perform the operations listed below.
View remote operands in the Operand Access table, then define and name regions.
To define regions:
1. Click and drag the cursor over regions to select them.
2. Click the Add New Region button.
Save region definitions in .vxt files.
19
Remote Access
In order to open a .vxt file, you must select the controller series (Configure>OPLC
model, either Vision or M90/91) which was selected when the .vxt file was saved.

Note
You can also write values to the M90 Database integers.
1. Enter values, then click write; all of the values in all of the defined regions are
written to the controller.
Use the Windows Clipboard to Cut/Copy/Paste values to/from the Operand Access
table and third-party editors such as Excel.
21
Remote Access
Note The Paste destination within Operand Access must be large enough to hold
the Clipboard contents. Clipboard contents are pasted to the right and down.
Export/Import Operand values to/from an Excel spreadsheet customized to
Unitronics' PLC Data Types.
Within Excel, values can be edited, imported to Operand Access, then written to the
controller
To export real-time values from the PLC to Excel:
1. Create a region containing the operand values you wish to export.
2. Select Read Regions in order to update those values,.
3. Select Export to Excel.
Note
Not all operand values are updated with real-time values when you run On
Line mode. When you run On Line mode, only the values that are displayed within the
Operand Access window are updated. Operands that are not displayed in the Operand
Access window during On Line are not updated.
Therefore, running On Line mode immediately before Export to Excel does not
guarantee the export of all updated operand values.

Information Mode
Information Mode is a utility that is embedded in the operating system of the controller. Via
Information Mode, you can view data on the LCD screen, use the controller’s keyboard to
directly edit data, and perform certain actions such as resetting the controller. You can enter
Information Mode at any time without regard to what is currently displayed on the LCD screen.
Enter Information Mode by pressing the <i> key for a few seconds. The default password is
1111.
Viewing data does not
affect the controller’s
program. Performing
actions, such as
initializing the controller,
can influence the
program.
Note When you use
Information Mode, the
keyboard is dedicated to
that purpose. The keys
return to normal
application functions
when you exit
Information Mode.
Using Information Mode
1. To enter Information mode, press the <i>button on the Vision’s keyboard.
2. Enter your password. The default password is 1111. This password remains in effect
until you change it via the Information Mode screen described in the table below.
3. The controller enters Information Mode, showing the first category, Data Types.
The controller will block entry
into Information mode until the
correct password has been
entered. This is why you must
record any password you set for
your controller.
The data in Information Mode is
arranged in Categories. Each
Category contains several
Subjects. You navigate
Information Mode by using the
keyboard buttons.
To exit Information mode, press
the <ESC>button on the Vision’s
keyboard. Each press returns
one level up. Press the number
of times necessary to exit.
