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

Programming

Software All-in-one UniLogic™ software, for hardware configuration,

communications, and HMI/PLC applications, available as a free

download from Unitronics web site.

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.

9BWiring

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.

15BWiring Procedure

Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm

–3.31 mm

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.

16BWiring Guidelines

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.

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.

Tx/Rx– (A)

Signal Ground

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 CPU-

for-Panel.

CANbus Wiring

-V CANbus Power & Signal Common

Use a shielded twisted-pair cable.

DeviceNet®, shielded twisted-pair cable

is recommended.

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.

DeviceNet®

cable connection:

OTE

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%.
