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.
1 Number of I/Os may vary according to I/O module selection.

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 6. 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.

Installation Guide
Mounting
Before you begin, note that the mounting panel cannot be more than 5 mm thick.
1. Make a panel cut-out according to the dimensions in the next figure.
Cut-out Dimensions
2. Slide the controller into the
cut-out, ensuring that the
rubber seal is in place.
3. Push the 4 mounting brackets
into their slots on the sides of
the controller as shown in the
figure to the right.
4. Tighten the bracket screws
against the panel. Hold the
bracket securely against the
unit while tightening the screw.
5. When properly mounted, the controller is squarely situated in the panel cut-out as shown below.

Wiring: General
Do not touch live wires.
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).
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.
Power Supply
The controller requires an external 24VDC power supply. The permissible input voltage range is
20.4-28.8VDC, with less than 10% ripple.
A non-isolated power supply can be used if a 0V signal is connected to the chassis.
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.
Do not connect either the ‘Neutral or ‘Line’ signal of the
110/220VAC to device’s 0V pin.
In the event of voltage fluctuations or non-conformity to
voltage power supply specifications, connect the device
to a regulated power supply.
To maximize system performance, avoid electromagnetic interference by:
Mounting the controller on a metal panel.
Earthing the controller’s power supply: connect one end of a 14 AWG wire to the chassis
signal; connect the other end to the panel.
Note: 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

Installation Guide
Communication Ports
This series comprises 2 RS232/RS485 serial ports and a CANbus port.
Turn off power before making communications connections.
Caution
Always use the appropriate port adapters.
Serial Communications
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 on page 6.
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 the signals between the adapter and port.
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 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.
