UniStream™ CPU-for-Panel
Installation Guide
USC-P-B10
Unitronics’ UniStream™ platform comprises control devices that provide robust, flexible
solutions for industrial automation.
This guide provides basic installation information for the UniStream™ CPU-for-Panel.
Technical specifications may be downloaded from the Unitronics website.
The UniStream™ platform
comprises CPU controllers, HMI
panels, and local I/O modules
that snap together to form an
all-in-one Programmable Logic
Controller (PLC).
Expand the I/O configuration
using a Local Expansion Kit or
remotely via CANbus.
CPU-for-Panel
CPUs are Programmable Logic Controllers (PLCs), the heart of the
UniStream™ platform.
The CPU-for-Panel cannot operate independently. It must be plugged
into the back of a UniStream™ HMI panel. The panel provides the CPU’s
power source. The CPU-for-Panel comprises:
 IO/COM Bus connector for interfacing Uni-I/O™ & Uni-COM™ modules
 Isolated RS485 and CANbus ports
 Backup battery
HMI Panels
Available in
different
dimensions
A high-resolution touch screen provides the operator interface for the
system and the physical foundation for a PLC+HMI+I/Os all-in-one
controller.
The DIN-rail structure on the panel’s back is designed to physically
support a CPU-for-Panel controller, Uni-I/O™ and/or Uni-COM™
modules.
Each panel comprises:
 AUX connector to support the CPU
 1 audio-out 3.5mm jack
 1 microSD slot
 2 type A, USB host ports and 1 Mini-B USB device port
 2 Ethernet ports, RJ45, 10/100 Mbps
 1 power input connector, 12/24 VDC
I/O Options
Integrate I/Os into your system by using:
 On-board I/Os: snap onto the panel for an all-in-one configuration
 Local I/O via a Local Expansion Kit
 Remote I/O via EX-RC1

Battery: Back-up, Installation, and Replacement
Backup
In order to preserve back-up values for RTC and system data in the event of power off, the
battery must be connected.
Battery Installation
The CPU is shipped with a battery installed, but with a plastic Battery pull-tab inserted in
the battery compartment. Pull out the Battery pull-tab during installation in order to
connect the battery.
Battery Replacement
 Use proper precautions to prevent Electro-Static Discharge (ESD) while servicing
the battery.
Caution

 To preserve back-up values for RTC and system data during battery
replacement, the CPU-for-Panel must be powered from the HMI Panel.

1. Open the CPU door and remove the battery cover.
2. Remove the used battery and insert the new one, ensuring that
the polarity is aligned with the polarity drawing as shown in the
accompanying figure.
3. Replace the battery cover.
4. Dispose of the used battery according to local and national
standards and regulations.
Battery Polarity
Installation
 Turn off system power before connecting or disconnecting any modules or devices.
 Use proper precautions to prevent Electro-Static Discharge (ESD).
The AUX connector on the back of the HMI panel provides the connection point for the
CPU-for-Panel, including power.
The DIN-rail type structure on the back of the panel provides the
physical support.
1. Remove the AUX connector cover from the panel (the cover
may be saved for future use).
2. If a Uni-I/O™ or Uni-COM™ module, or a Local Expansion Kit is
to be connected to the CPU-for-Panel, remove the IO/COM Bus
connector cover.
3. Plug the CPU-for-Panel into the HMI Panel AUX connector. If an
adjacent module is already installed, slide the CPU-for-Panel
into place via the guide tunnels shown in the accompanying
figure.
4. Verify that the DIN-rail clips located on the top and bottom of
the CPU-for-Panel have snapped onto the DIN-rail structure on
the back of the panel.
Removing the CPU-for-Panel
1. Power off the HMI Panel before removing the CPU-for-Panel.
2. Disconnect the RS485 and the CANbus connectors (if relevant).
3. Disconnect the module connected to the CPU (by pushing its Bus Connector lock to the
right).
4. On the CPU-for-Panel pull the top DIN-rail clip up and the bottom clip down.
5. Pull the CPU-for-Panel out of its place.

About the CPU’s IO/COM Bus Connector
The IO/COM Bus connector on right side of the CPU-for-Panel provides the electrical
connection point for a Uni-I/O™ or Uni-COM™ module or Local Expansion kit. The
connector is shipped covered by a protective cover, protecting the connector from debris,
damage, and ESD.
 When no module is connected to the CPU, its IO/COM Bus Connector Cover must
remain installed.
 Turn off system power before connecting or disconnecting modules.
Wiring
9B
 This equipment is designed to operate only at 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
point.
 Do not touch live wires.
 All wiring activities should be performed while power is OFF.
 Unused points should not be connected (unless otherwise specified). Ignoring this
directive may damage the device.
 Double-check all wiring before turning on the power supply.
Caution
 To avoid damaging the wire, use 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.
 Install at maximum distance from high-voltage cables and power equipment.
Wiring Procedure
15B
Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm2 –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.
Wiring Guidelines
16B
In order to ensure that the device will operate properly and to avoid electromagnetic
interference:
 Use a metal cabinet. Make sure the cabinet and its doors are properly earthed.
 Use wires that are properly sized for the load.
NOTE

For detailed information, refer to the document System Wiring Guidelines, located in
the Technical Library in the Unitronics’ website.

Communication Ports
 Turn off power before making any communications connections.
RS485
Use the RS485 port to create a multi-drop network.
The CPU-for-Panel is shipped with a 4 pin RS485
terminal block. This connector is marked with a pin
assignment that is identical to the corresponding
marking on the CPU-for-Panel.

Functional Ground
 Use shielded twisted-pair cable, in compliance with EIA RS485 specifications.
 When wiring each node, connect the cable shield to the functional ground point of the
RS485 terminal block.
Caution
 In order to avoid ground-loops, do not connect the RS485 functional ground
terminal to the earth of the system, as it is internally connected to the HMI
panel’s functional ground point.
RS485 Termination
Use the DIP switches shown in the panel diagram
on page 3 to set the RS485 termination according
to the accompanying table.
The device is shipped with both its DIP switches set
to ON; change settings if the device is not at one of
the ends of the RS485 network.

CANbus
Use the CANbus port for all CANbus communications including integration of Remote I/Os
via EX-RC1.
The CPU-for-Panel is shipped with a 5 pin CANbus terminal block. This connector is
marked with a pin assignment that is identical to the corresponding marking on the CPUfor-Panel.

cable connection:
 When wiring each node, connect the
cable shield to the functional ground
point of the CANbus terminal block.
 Connect the CANbus cable shield to the
system earth at only one point near the
power supply.
NOTE
The CPU-for-Panel CANbus port is
internally powered and does not require
an external power-supply. This means
that you can either connect the +V point
in the CPU’s CANbus connector to an
external power supply, or leave it
unconnected.
Do not use the +V point for any other
purpose.
CANbus Termination
Place termination resistors at each end of
the CANbus network. Resistance must be
set to 121Ω, 1/4W, 1%.
