WARNING

Do not try to disassemble a Unit or touch the terminal block while the power is ON. Doing this can cause electrical shock.

Make sure that the voltage and current input to the Units are in the specified ranges. If the voltage and current are not in the specified ranges, there can be Unit malfunctions or fire.

Turn OFF the I/O power supply to a SmartSlice I/O Unit before you replace it with the online replacement procedure. If there is external power to a terminal for a Relay Output Slave, for example, turn OFF the external power before you replace the SmartSlice I/O Unit. If you replace a Slave I/O Unit with the power ON, incorrect outputs, incorrect inputs, or electric shock can occur.

Safety Precautions

Apply safety measures in external circuits (that is, not in the SmartSlice I/O Terminal) to keep safety in the system. These measures must keep safety if a malfunction in the control system or other external factor which has an effect on the control system causes a problem. Include the items below. Not doing this can cause serious accidents.

• There must be emergency stop circuits, interlock circuits, limit circuits, and other safety measures in external control circuits.

• The SmartSlice outputs can stay ON or OFF because of welding or burning of the output relays, or destruction of the output transistors. As a countermeasure for such errors, there must be external safety measures to keep safety in the system.

• The SmartSlice I/O Terminal will continue operating when one or more I/O Units are missing from the SmartSlice I/O Terminal. The other I/O Units will continue the control operations, including the control of the outputs. As a countermeasure for such errors, there must be external safety measures to keep safety in the system.

The CPU Unit refreshes I/O when the program is stopped in PROGRAM mode. Fully make sure that it is safe before changing the status of bits or words in memory allocated to Output Slaves, Special I/O Units, or CPU Bus Units. If you change the bits or words allocated to a Slave or Unit, you could cause incorrect operation of the loads connected to the Slave or Unit. The operations below will change memory status.

• Transferring I/O memory data to the CPU Unit from a Programming Device

• Changing present values in memory from a Programming Device

• Force-setting or force-resetting bits from a Programming Device

• Transferring I/O memory files from a Memory Card or EM file memory to the CPU Unit

• Transferring I/O memory from a host computer or from a PLC on a network

Precautions for Safe Usage

• Put a Unit in the special box during transportation. Make sure that the Unit is moved carefully, and not given too much vibration or shock during transportation.

• Do not let a Unit fall or give it too much vibration or shock. This can cause malfunction or cause damage to the Unit.

• Install the SmartSlice I/O Terminal correctly on DIN Track.

• Be sure that you correctly lock the terminal block, the communications cable connectors, and other items with locking devices.

• Correctly connect the Units as this manual shows.

• Interference between the Flat Cables for more than one CompoNet System can cause operation that is not stable. Keep the Flat Cables for different CompoNet Systems apart by a minimum of 5 mm. Interference can occur for Sheathed Cable or Unsheathed Cable.

• Do not let metal objects enter the Unit when connecting or installing it.

• Connect ferrules to the wires when you connect the wires. Do not connect stranded wires directly to terminals.

• Use the specified communications cables and connectors.

• Use the correct polarity when connecting the terminals.

• Put the ferrules fully into the holes.

• Do a full check of the terminal block before you attach it.

• Do not bend the cables to more than their normal bending radius or pull on the cables.

• Obey the following precautions when connecting communications cables.

• Keep the communications cables away from the power lines or high-tension lines.

• Do not bend the communications cables with too much force.

• Do not pull on the communications cables with too much force.

• Do not put objects on the communications cables.

• Put the communications cables in ducts.

• If the power supply conditions are bad, install countermeasures to make sure that the power supply always has the rated voltage.

• You must make interlock circuits, limit circuits, and other safety measures in circuits that are external to the control system.

• Use the power supply voltage which this manual specifies.

• Make sure that there will be no problems when the Unit changes to fixed allocations for the I/O Areas before you clear the Registration Table. (You set user remote I/O allocations in the Registration Table.)

• Do not let the communications distance be higher than the specified value.

• Install circuit breakers and other safety measures to prevent Unit damage which short-circuits in external wires can cause.

• Install failsafe measures to make sure that the system is safe if disconnected signal lines or short power interruptions cause incorrect signals.

• Always obey the voltage specifications for power supply connections and I/O jumpers. Incorrect connections can cause malfunctions.

• Do not apply a voltage or connect a load which is larger than the maximum switch capacity to an Output Slave.

• Do not apply a voltage which is larger than the rated voltage to an Input Slave.

• Be sure there are no mistakes in connections or switch settings before you turn ON the power supply.

EC Directives

Applicable Directives

•EMC Directive

• Low Voltage Directive

Concepts

EMC Directive

The SmartSlice I/O Terminals are electrical devices which are installed in a machine in application. The Terminals comply with the EMC Directive. This makes it easier for the machine in which a Terminal is installed to more easily comply with the EMC directive. (See note.) The EMC-related performance of the OMRON devices which comply with EC Directives changes with the machine in which they are installed. This includes the configuration, connections, and other conditions of the machine. The customer must do the checks to make sure that the devices and the machine conform to EMC standards. Note: The applicable EMC (electro-magnetic compatibility) standards are EN 61131-2 and EN 61000-6-2 for EMS (electro-magnetic susceptibility) and EN 61131-2 and EN 61000-6-4 for electro-magnetic interference. The 10-m regulations apply for radiated emissions.

EC Directives

Low Voltage Directive

Devices which operate at voltages from 50 to 1,000 VAC or 75 to 1,500 VDC must comply with the related safety requirements. The applicable standard is EN 61131-2.

Complying with EC Directives

The SmartSlice I/O Units comply with EC Directives. These measures are necessary for the machine containing a SmartSlice I/O Units to comply with the EC Directives.

1. You must install the SmartSlice I/O Units in a control panel.

2. You must use reinforced insulation or double insulation for the DC power supplies used for the Unit power supplies, and the I/O power supplies. Make sure that the outputs are stable if a 10-ms interruption occurs at the input. We recommend the S82J Power Supply which is made by OMRON. (See note.)

3. The SmartSlice I/O Units which conform to EC Directives conform to the EMI standards (EN 61131-2 (Immunity Zone A), EN 61000-6-2, and EN 61000-6-4). The radiated emission properties (10-m regulations) can change with the configuration of the control panel, other devices which are connected to the control panel, connections, and other conditions. You must make sure that the completed machine complies with EC Directives.

4. Compliance tests were done with I/O wires of a maximum length of 30 m.

Note: Compliance tests for EMC standards were done with the recommended power supply.

The SmartSlice I/O System Section 1-1

1-1 The SmartSlice I/O System

SmartSlice is a building-block style remote I/O system which you make from a Communications Unit and a number of SmartSlice I/O Units. Each SmartSlice I/O Unit has a small number of I/O points. You can use a SmartSlice I/O system to decrease wire connection, installation, and space requirements.

The CompoNet SmartSlice System is a new type of network. It has the basic features of previous CompoNet Slave Units and the features of a SmartSlice I/O system. The CompoNet Communications Unit and installed SmartSlice I/O Units together make a “SmartSlice I/O Terminal.” You can mix SmartSlice I/O Units to make a system for different applications. You can also use many other functions. The other functions include functions to monitor the operation of the system.

This is an example of a CompoNet SmartSlice System.

Slice I/O Units

You can connect a maximum of 64 Slice I/O Units to one CompoNet Communications Unit.

Features of the CompoNet SmartSlice I/O Terminals Section 1-2

1-2 Features of the CompoNet SmartSlice I/O Terminals

This section tells you the features of a CompoNet SmartSlice System.

Each SmartSlice I/O Terminal Is One CompoNet Node

You can control a CompoNet Communications Unit with a maximum of 64 connected SmartSlice I/O Units as one Slave from the CompoNet Master Unit.

Remote I/O Communications

You can use remote I/O communications to share I/O data between the CompoNet Master Unit and the SmartSlice I/O Units through the CompoNet Communications Unit. You can also allocate status data of the CompoNet Communications Unit in the CompoNet Master Unit. You can also use the CXIntegrator or explicit messages to allocate status information on the network participation status of SmartSlice I/O Units in the CompoNet Master Unit.

Easy Startup

All you must do to start operation is to set the node address with the rotary switches and to set the DIP switch. These switches are on the CompoNet Communications Unit. When you turn ON the power supply, the CompoNet Master Unit automatically reads the Unit configuration and allocates I/O to the SmartSlice I/O Terminals. You do not have to set parameters with special software.

Easy I/O Connections

All SmartSlice I/O Units connected to the CompoNet Communications Unit have screwless clamp terminals. All you must do is to put 10-mm ferrules on the wires and then push the ferrules into the screwless clamp terminals. It is not necessary to tighten screws.

Table Registration

You can use the DIP switch on the CompoNet Communications Unit to record the connected SmartSlice I/O Units in a table. The table tells the sequence and I/O capacity of each SmartSlice I/O Unit. After you complete registration, the CompoNet Communications Unit will compare the configuration with the table each time that the power is turned ON. You can set a status flag in the CompoNet Master Unit to show when the configurations do not agree.

Back Up and Restore Parameters

You can use the DIP switch on the CompoNet Communications Unit to back up the parameters in the I/O Units to memory in the CompoNet Communications Unit. You can do this for maintenance, for example, when you replace an I/O Unit. You can also use the DIP switch to restore the parameters in the CompoNet Communications Unit to the I/O Units after you replace an I/O Unit.

Online Replacement of I/O Units

SmartSlice I/O Units have a base block, main block, and terminal block. You can disconnect these blocks. With this block structure, you do not have to turn OFF the Unit power supply to replace SmartSlice I/O Units.

Note You must turn OFF the I/O power supply to the SmartSlice I/O Unit before you

replace it. If there is external power to a terminal on the SmartSlice I/O Unit, also turn OFF the external power before you replace the SmartSlice I/O Unit.

Automatic Baud Rate Recognition

The CompoNet Communications Unit automatically finds the communications baud rate of the CompoNet Master Unit. It is not necessary to set the baud rate.

Features of the CompoNet SmartSlice I/O Terminals Section 1-2

Software Setting of I/O Allocations

You can record the node addresses and I/O configurations of Dummy Units in the registration table to prepare for expansion of SmartSlice I/O Units. When you add the I/O Units, it will not be necessary for you to set the node addresses or I/O configurations. It will also not be necessary to change the ladder programming very much. You can also write the ladder programming for the full configuration and set the Units that you will add as Dummy Units. When you change the unit configuration, it will not be necessary to change the I/O map.

Unit Conduction Time Monitor

The Unit Conduction Time Monitor records the total time that the internal circuit power in DeviceNet Communications Unit is ON. You can set a threshold in the CompoNet Communications Unit to tell the CompoNet Master Unit when the conduction time is longer than the threshold. You can set the threshold or read the conduction time with the CX-Integrator or with an explicit message.

Unit Comments

You can set a comment (for example, a name or the application) for each CompoNet Communications Unit to record the name in the CompoNet Communications Unit. You can use the comments to easily identify CompoNet Communications Units when you set or monitor parameters with the CX-Integrator. You can set or read the comments with the CX-Integrator or with an explicit message.

Communications Error History Monitor

There is a communications error history in the CompoNet Communications Unit. It records the four newest errors in communications with the CompoNet network and the 64 newest errors in communications in the SmartSlice I/O Terminal. You can read the communications error status with the CX-Integrator or with an explicit message.

Last Maintenance Date

You can record the last date on which you did maintenance in the CompoNet Communications Unit. You can write the last maintenance date with the CXIntegrator or with an explicit message.

Communication Unit.

The CompoNet Communications Unit is the interface with the CompoNet network. You connect it to the CompoNet Master Unit. You connect each CompoNet Communications Unit to SmartSlice I/O Units with the number of I/O points which is necessary in each location. The CompoNet Communications Unit does communications with the SmartSlice I/O Units.

The CompoNet Communications Unit temporarily keeps the I/O data from the SmartSlice I/O Units which are connected to it. I/O data is transferred to and from the CompoNet Master Unit all at one time during remote I/O communications.
