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.

Page 10

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

Page 11

Precautions for Safe Usage

• 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.

Page 23

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.

Precaution for Correct Usage

• You must install an End Unit (GRT1-END) on the end of the last block in the SmartSlice I/O Terminal.

• There are limits for each block to the capacity of the Unit power supply and the I/O power supply. If the Unit power consumption of the SmartSlice I/O Units in one block is higher than 80 W, you must divide the SmartSlice I/O Terminal. Refer to Precautions When Connecting the Power Supplies on page 36 for more information.

Setting the Node Addresses Section 5-1

5-1 Setting the Node Addresses

There are two types of node on a CompoNet Network: The slaves and a CompoNet Master Unit. The slaves connect to external I/O. The Master Unit controls the CompoNet Network and sends I/O data between the PLC and the slaves.

A SmartSlice I/O Terminal is a slave on a CompoNet Network. You must set a node address for it.

You can use the node address to find the first word that is allocated to the SmartSlice I/O Terminal.

The SmartSlice I/O Terminal is a Word Slave.

3. Turn ON the power supplies.

Note If you set a node address that is the same as a different node, the NS indica-

tor on the CompoNet Communications Unit will come ON in red. A network configuration error will occur and normal communications will not be possible.

Page 60

Unit Numbers for SmartSlice I/O Units Section 5-2

5-2 Unit Numbers for SmartSlice I/O Units

Unit numbers identify the SmartSlice I/O Units connected in a SmartSlice I/O Terminal.

The system automatically allocates the unit numbers for SmartSlice I/O Units. The SmartSlice I/O Unit on the right side of the CompoNet Communications Unit is Unit 1. The other SmartSlice I/O Units get unit numbers 2 to 64 in sequence from the left side to the right side of the SmartSlice I/O Terminal.

The CompoNet Master Unit uses the unit numbers to allocate I/O.

The system automatically allocates unit numbers from the left side to the right side.

CompoNet Communications Unit

Note (1) The node address of the SmartSlice I/O Terminal has no relation to the

unit numbers of the SmartSlice I/O Units.

(2) The I/O Power Feed Units (for example, the GRT1-PD2 and GRT1-PD8)

do not get unit numbers.

I/O Allocations to CompoNet Master Unit Section 5-3

5-3 I/O Allocations to CompoNet Master Unit

The system allocates words in an Input Area and Output Area to the SmartSlice I/O Units using the node number of the SmartSlice I/O Terminal. These words are in the I/O memory of the CPU Unit of the CompoNet Master Unit.

You can also use the CX-Integrator to set I/O allocations.

Note You can also use Software I/O Allocation Mode to allocate words to a Dummy

Unit. A Dummy Unit is a SmartSlice I/O Unit that is not connected in the SmartSlice I/O Terminal. Refer to 6-7 Software Setting of I/O Allocations on page 60 for more information.

1. Status of the CompoNet Communications Unit The Status Word shows the status of the SmartSlice I/O Units in the SmartSlice I/O Terminal.

2. I/O Data for SmartSlice I/O Units The system allocates the bits or words to the SmartSlice I/O Units in the SmartSlice I/O Terminal in the same sequence as the unit numbers. It allocates lower bits first and words with lower addresses first.

Page 62

I/O Allocations to CompoNet Master Unit Section 5-3

• The system allocates 2 bits to each Bit Unit starting from the lower bits. Bit Units are SmartSlice I/O Units that have two or more bits of I/O (for example, the GRT1-ID4/OD4).

• The system allocates words to each Word Unit starting from words with lower addresses. Word Units are SmartSlice I/O Units that have one or more words of I/O (for example, the GRT1-AD2/DA2C).

Refer to the GRT1 Series SmartSlice I/O Units Operation Manual (Cat. No. W455) for information on each Bit Unit and Word Unit model of SmartSlice I/O Units and specifications.

3. Participation Status of the SmartSlice I/O Units The system allocates 8 words for the participation status of the SmartSlice I/O Units.

Allocation Example The system allocates words to the SmartSlice I/O Units in the sequence in

which they are connected (in the sequence of unit numbers). The models of the SmartSlice I/O Units have no effect on the sequence of allocations.

Unless you use the CX-Integrator to set I/O allocations, the system always allocates words in the same sequence starting from the first word for the node address. The sequence is the status, left SmartSlice I/O Unit, subsequent SmartSlice I/O Unit on the right side, other SmartSlice I/O Units. The system allocates words to Input Units in the Input Area and to Output Units in the Output Area.

The system allocates words for status of the CompoNet Communications Unit and the participation status of the SmartSlice I/O Units in the Input Area.

Bits That Are Not Used

The figure below shows a 4-bit Unit (Unit 5) that gets two bits in one word and two bits in the subsequent word. The subsequent Unit (Unit 6) is a Word Unit that gets two words. The system allocates the subsequent two full words to this Unit and does not allocate the other bits in the +1 word.

Unit 8 in the figure is an 8-bit Unit. The system allocates only full words to 8bit Units. In this example, the system allocates the subsequent full word (the +5 word) and does not allocate the other bits in the +4 word. (The first four bits in the +4 word are for Unit 7.)

6-2 Registration Table

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.

When the power is subsequently turned ON, the CompoNet Communications Unit automatically compares the information in the Registration Table with the connected SmartSlice I/O Units.

6-2-1 Making a Registration Table

Precaution for Correct Usage

• Before making the Registration Table, make sure that all SmartSlice I/O Units are participating in communications. The TS indicators must be lit in green.

• Before making the Registration Table, make sure that pin 2 (I/O) on the DIP switch is OFF (Automatic I/O Allocation Mode). You cannot make the Registration Table if pin 2 is ON (Software I/O Allocation Mode).

Page 74

Registration Table Section 6-2

Turn ON pin 1 (REGS) on the DIP switch while the power to the SmartSlice I/O Terminal is ON.

The CompoNet Communications Unit will read the I/O configuration information and make a Registration Table.

The CompoNet Communications Unit will overwrite a previous Registration Table with the new one.

Power ON

Use the procedures in the table below if there are differences between the Registration Table and the I/O configuration.

Cause Procedure

Unit failure caused a SmartSlice I/O Unit to not be in the Registration Table.

There is a SmartSlice I/O Unit that is not in the Registration Table.

Correct the cause (for example, replace the Unit), turn OFF pin 1 (REGS) on the CompoNet Communications Unit, and reset the Unit power supply. Then turn ON pin 1 to make the Registration Table again.

Turn OFF pin 1 and reset the Unit power supply. Then turn ON pin 1 to make the Registration Table again.

Note If you start with CompoNet Communications Unit with pin 1 ON and no Regis-

tration Table, the TS indicator will flash in red. This shows a Registration Table Verification Error.

6-2-3 Clearing the Registration Table

To clear the Registration Table, turn ON the power supply to the CompoNet Communications Unit when pin 1 (REGS) is OFF.

Page 76

Backup Function Section 6-3

6-3 Backup Function

The backup function saves the parameters from the SmartSlice I/O Units to memory in the CompoNet Communications Unit.

If you back up the parameters, you can use the automatic restore function to download the parameters in the CompoNet Communications Unit to the SmartSlice I/O Units. This is useful when you replace SmartSlice I/O Units.

We recommend that you back up the parameters at a set interval to prevent losing the parameter for SmartSlice I/O Unit failures.

Turn pin 4 OFF and then ON when pin 1 or pin 2 is ON.

These conditions are necessary to back up the parameters. Do a check of these conditions before you back up the parameters.

• Pin 1 (REGS) or pin 2 (I/O) on the DIP switch on the CompoNet Communications Unit must be ON.

• All SmartSlice I/O Units must be participating in communications (to back up the parameters for all SmartSlice I/O Units at one time).

6-3-1 Backup Procedure

Turn pin 4 (BACK) OFF and then ON in 3 seconds.

Power ON

CompoNet Communications Unit

The CompoNet Communications Unit will back up the parameters from all Slice I/O Units.

#1 #2 #3 #4

3 s or less

Pin setting

ON OFF ON

The CompoNet Communications Unit will start to back up the parameters.

Precaution for Correct Usage

• Do not turn OFF the power supply or reset the CompoNet Communications Unit from the CX-Integrator during the backup operation. The backup data will not be correct.

6-3-2 Doing a Check of the Backup Results

The TS indicator on the CompoNet Communications Unit flashes green during the backup operation. The backup operation is completed when the TS indicator goes OFF.

If the CompoNet Communications Unit could not back up the parameters, the TC indicator will come ON in red for 2 seconds.

Note (1) To clear the backup data, reset the Unit power supply with pin 1 turned

OFF. This operation will clear the Registration Table and the backup data.

Page 77

Automatic Restore Function Section 6-4

(2) The CompoNet Communications Unit will clear the backup data if you

change the operating mode. The CompoNet Communications Unit will clear the backup data if you back up the parameters with pin 2 (I/O) ON (Software I/O Allocation Mode) and then make the Registration Table from the CX-Integrator.

6-4 Automatic Restore Function

After you replace a SmartSlice I/O Unit, you can use the Automatic Restore Function to automatically download the parameters in the CompoNet Communications Unit to the SmartSlice I/O Units.

Turn ON pin 3 when pin 1 or pin 2 is ON.

These conditions are necessary to automatically restore the parameters. Do a check of these conditions before you restore the parameters.

• There must be backup data in the CompoNet Communications Unit.

• Pin 1 (REGS) or pin 2 (I/O) on the DIP switch on the CompoNet Communications Unit must be ON.

• The new SmartSlice I/O Unit must have the same unit number and model number as the previous SmartSlice I/O Unit, but a different serial number.

6-4-1 Restore Procedure

1,2,3... 1. Turn ON pin 3 (ADR) on the CompoNet Communications Unit to enable the

Automatic Restore Function.

2. Turn OFF the I/O power supply and replace the SmartSlice I/O Unit. Refer to the GRT1 Series SmartSlice I/O Units Operation Manual (Cat. No. W455) for information on how to replace SmartSlice I/O Units.

The CompoNet Communications Unit will detect the SmartSlice I/O Unit that you replaced and it will download the parameters to it.

Power ON

CompoNet Communications Unit

The CompoNet Communications Unit will automatically download the parameters to the new Unit.

#1 #2 #4

Parameter

!WARNING Turn OFF the I/O power supply to a SmartSlice I/O Unit before you replace it.

Incorrect inputs, incorrect outputs, or electrical shock can occur if you do not turn OFF the I/O power supply. 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.

Precaution for Correct Usage

• Do not turn OFF the power supply or reset the CompoNet Communications Unit from the CX-Integrator during the restore operation. The restored data will not be correct.

3. Turn ON the I/O power supply.

Page 78

Replacing Units Online Section 6-5

6-4-2 Doing a Check of the Restore Results

The TS indicator on the CompoNet Communications Unit flashes green during the restore operation. The restore operation is completed when the TS indicator stops flashing.

If the CompoNet Communications Unit restored the parameters, it will reset the SmartSlice I/O Units automatically and the TS indicator on the CompoNet Communications Unit will come ON in green.

If the CompoNet Communications Unit could not restore the parameters, the TS indicator on the CompoNet Communications Unit will come ON in red for 2 seconds. The Automatic Restore Monitor Flag (bit 13 in the status word for the CompoNet Communications Unit) will also turn ON.

If the new SmartSlice I/O Unit is not the same model as the previous Unit, the TS indicator on the CompoNet Communications Unit will flash in red.

6-5 Replacing Units Online

You can replace a SmartSlice I/O Unit in the SmartSlice I/O Terminal without turning OFF the Unit power supply.

A SmartSlice I/O Unit has a base block, main block, and terminal block. When you replace a SmartSlice I/O Unit, do not replace the base block and replace the other blocks.

Communications with the other SmartSlice I/O Units will continue while you replace the SmartSlice I/O Unit.

If you back up the parameters, you can turn ON pin 3 (ADR) with pin 1 (REGS) or pin 2 (I/O) ON to automatically restore the parameters.

Refer to the GRT1 Series SmartSlice I/O Units Operation Manual (Cat. No. W455) for information on how to replace SmartSlice I/O Units.

!WARNING Turn OFF the I/O power supply to a SmartSlice I/O Unit before you replace it.

Precaution for Correct Usage

• Replace only one SmartSlice I/O Unit at a time.

• Always replace a SmartSlice I/O Unit with a Unit of the same model number. If you use a different model, incorrect outputs can occur or restoring the parameters will not be possible.

• If it is necessary to replace the base block, turn OFF the unit power supply and the I/O power supplies and replace the full SmartSlice I/O Unit. You can also use the Automatic Restore Function after you replace the full SmartSlice I/O Unit.

6-6 Automatic Baud Rate Recognition

The CompoNet Communications Unit will automatically detect the baud rate set in the CompoNet Master Unit and use it for communications with the CompoNet Master Unit.

Page 79

Software Setting of I/O Allocations Section 6-7

The CompoNet Communications Unit will set the baud rate when it establishes communications with the CompoNet Master Unit. It will save the baud rate until the power supply is turned OFF.

Note If you change the baud rate of the CompoNet Master Unit, reset the power

supply of the CompoNet Communications Unit.

6-7 Software Setting of I/O Allocations

You can set Dummy Units in a Software Setting Table for SmartSlice I/O Units that are not in the SmartSlice I/O Terminal. The settings include the node numbers and I/O configurations.

When you then add the SmartSlice I/O Units, it will not be necessary for you to set the unit numbers or I/O configurations. It will also not be necessary to change the ladder programming very much.

The Software Setting Table contains the I/O configuration information (including the Dummy Units). You can use the CX-Integrator to set or read it.
