• Seven-segment Display
The number of connected CompoNet Slave Units is shown on the seven-segment display.
This enables easily checking system operation.
• Participation Flags and Communications Error Flags
The network participation status of CompoNet Slave Units can be checked at the PLC.
When a CompoNet Slave Unit joins the network, a Participation Flag that corresponds to the node
address of the Unit turns ON. If a CompoNet Slave Unit that was participating in the network is
disconnected from the network, a Communications Error Flag that corresponds to the node
address of the Unit turns ON. (Communications mode 0 to 3 must be set.)
• Automatic Baud Rate Detection
The CompoNet Slave Units will automatically detect and use the baud rate that is set in the Gateway Unit. Setting the baud rate is not necessary for any of the CompoNet Slave Units.
z Repeater Units for Greater Flexibility
Repeater Units can be used in a CompoNet network to enable the following network expansions.
• Extending the cable length
• Increasing the number of nodes
• Branching from the trunk line
• Changing the type of cable
Repeater Units can be used to extend up to two segment layers (called sub-trunk lines) from the
trunk line. Up to 64 Repeater Units can be connected per Gateway Unit and up to 32 Repeater Units
can be connected per segment.
Note: Supply communications power to a sub-trunk line from the Repeater Unit.

• Gateway Unit Detection of Network Participation, Errors, and Status
When a CompoNet Slave Unit joins the network, a Participation Flag that corresponds to the node
address of the Unit turns ON. If a CompoNet Slave Unit that was participating in the network is
disconnected from the network, a Communications Error Flag that corresponds to the node
address of the Unit turns ON.
Network status, such as communications errors and duplicated Slave Unit node addresses, and
Slave Unit diagnostic results are detected by the Gateway Unit and displayed on the seven-segment display on the front panel and reflected in the Status Flags. (Communications mode 0 to 3
must be set.)
• Registration Table
A table of the Slave Units that should be participating at the nodes (including the node addresses
and corresponding Slave Unit model numbers) can be registered to verify the Slave Units actually
participating in the network and prevent unregistered Slave Units from participating in the network.
• Communications Status on Gateway Unit Seven-segment Display
The seven-segment display on the front of the Gateway Unit can be used to check communications status. The number of connected nodes is normally displayed, but if an error occurs, the
error code is displayed in hexadecimal and the error node address is displayed in decimal.

CompoNet Network Start/Stop Conditions
• The CompoNet network will start when the power supply to the Gateway Unit and the communications power supply to the Slave Units are turned ON.
Note: Overall communications will not stop even if there is a verification error for the registration table or a dupli-
cated slave address.
• If data links cannot operate on the CC-Link network (i.e., if the Error Status Flag in CC-Link Status is
ON), remote I/O communications for the CompoNet network will also stop.
If data links start on the CC-Link network, remote I/O communications for the CompoNet network will
also start.

Communications Errors on the CompoNet Network
A communications error occurs when a Slave Unit cannot respond normally to a communications
request from the Gateway Unit. The main causes of communications errors are given below.
• Failure of the Slave Unit
• Disconnected communications cable to the Slave Unit
• Communications power interruption
• Noise or other factor that prevents normal data reception from the Slave Unit
If a communications error occurs for a Slave Unit, the NS indicator on the front of the Gateway Unit will
flash red and “d9” will be displayed on the seven-segment display. Also, the Communications Error Flag
(bit 00 in the Status Area) will turn ON.

Participation Flags and Communications Error Flags
• To check whether Slave Units are normally participating in the network, the Participation Flags and
Communications Error Flags in the Status Area are used.
• Participation Flags:
A Participation Flag turns ON once the corresponding Slave Unit starts participating in the network after the system is started (i.e., when the power is turned ON). It remains ON even if the
Slave Unit stops participating due to a communications error.

4-1 Exchanging Data
• Communications Error Flags:
A Communications Error Flag turns ON if the applicable Slave Unit cannot communicate with the
Master Unit for any reason after the Slave Unit has joined the network (i.e., if the Participation Flag
is ON). It turns OFF when the error is removed.

Participating
Therefore, in the ladder program, the applicable Slave Unit has stopped participating when both the
Participation Flag and the Communications Error Flag are ON. Similarly, the applicable Slave Unit is
operating normally when the Participation Flag is ON and the Communications Error Flag is OFF.
Example: This example shows executing I/O with the applicable Slave Unit when the Participation Flag and
Communications Error Flag are combined and taken as a condition to confirm that operation is normal.

• One bit is allocated for each node address. Participation Flags and Communications Error Flags are
allocated for each node type (Word Input Slave Units, Word Output Slave Units, Bit Input Slave Units,
and Bit Output Slave Units). One word is allocated for each 16 Slave Units.
Note: For I/O Slave Units, Participation Flags and Communications Error Flags are allocated to the Unit only as an
Input Slave Unit.
Checking the Status of Participation Flags and Communications
Error Flags
The status of buffer memory allocated to Participation Flags and Communications Error Flags can be
monitored from the GX-Developer.
1. Select Online − Monitor − Device batch from the menu.
2. The Device Batch Monitor Dialog Box will be displayed and monitor conditions can be set as shown
below.
Example: The following example is for the following settings: Communications mode 3, First remote out-
put register (RWw) address: 0, Gateway Unit with station number 1.
The first address (W0) in the remote output register (RWw) area is registered.

In this example, we can see that one Word Input
Slave and one Word Output Slave are participating
in the network.
Supplemental Information
Write the ladder program so that it monitors the Gateway Unit and data link operating status to check
for errors on the CC-Link network.

4-1-3 Registration Table
Overview
A registration table is used to register Slave Units that are intended to participate at particular node
addresses (along with the models corresponding to the node addresses) to enable verifying that they
actually are participating. At the same time, using the registration table prevents unregistered Slave
Units and Slave Units of the wrong node addresses or models from participating in the network.

This function is enabled only in Registration Table Enable Mode, i.e., when pin 4 (REGS) is ON on the
Gateway Unit when the power is turned ON and the registration table data is normal. It can be used in
any communications mode.
If a Slave Unit is found to be not in agreement during the verification, the Registration Table Verification
Error Flag (status bit 01) will turn ON.

Operation
The operation for each case is as follows:
• If all registered Slave Units are participating within the Registered Slave Unit Participation Monitoring
Time*1 after the power is turned ON, the All Registered Slave Units Participating Flag (status bit 06)
will turn ON.
• If no unregistered Slave Units are participating, the Registration Table Verification Error Flag will
turn OFF.
• If any unregistered Slave Unit is participating, a verification error (unregistered Slave Unit) will
occur and the Registration Table Verification Error Flag will turn ON. At the same time, the NS
indicator on the front of the Gateway Unit will flash red and the seven-segment display will show
“d6.”
• If all registered Slave Units are not participating within the Registered Slave Unit Participation Monitoring Time*1 after the power is turned ON, a verification error (non-existent Slave Unit) will occur
and the Registration Table Verification Error Flag will turn ON. At the same time, the NS indicator on
the front of the Gateway Unit will flash red and the seven-segment display will show “d5.” If the applicable Slave Unit subsequently starts participating, the Registration Table Verification Error Flag will
turn OFF and the error display will be cleared.
Note: Remote I/O communications will not operate if pin 4 (REGS) is ON on the Gateway Unit when the power is
turned ON and the registration table data is not valid. The MS indicator on the front of the Gateway Unit will
flash red, and the seven-segment display will show “E8.”
If that occurs, create the registration table again.
*1 The Registered Slave Unit Participation Monitoring Time depends on the CompoNet baud rate as follows:
• 1.5 Mbps, 3 Mbps, or 4 Mbps: 20 seconds
• 93.75 kbps: 140 seconds
4
4-1-3 Registration Table
Creating the Registration Table
1. Start the CompoNet network and get the Slave Units to participate in the CompoNet network.
2. Make sure that pin 4 (REGS) is ON on the CompoNet DIP switch and press the REGIST CompoNet
setting button for at least 2 seconds.
The REG indicator in the CompoNet communications section will flash while the registration table is
being created.
The REG indicator will light after the registration table has been completed.
3. Turn ON pin 4 (REGS) on the CompoNet DIP switch and press the RESET CompoNet setting button
for at least 2 seconds.
The registration table will be enabled and will operate. The Registration Table Mode Flag (status bit
10) will turn ON (Registration Table Enable Mode).

Slave Unit Address Duplication Error
In any of the following cases, a Slave Unit address duplication error will occur and the Address Duplication Error Flag (status bit 03) will turn ON for the Slave Unit that joined the network later.
At the same time, the NS indicator on the front of the Gateway Unit will flash red and the seven-segment display will show “d0.” Remote I/O communications will not stop.
• There is another Slave Unit for which the same node address is set.
(For example, both Slave Units are set to node address N.)
Note: An address duplication error will occur if the same node address is set for two Slave Units in the same allo-
cation area. This applies only if both are Input Slave Units or both are Output Slave Units.
4
4-1 Exchanging Data
• Different node addresses are set, but the allocated memory areas overlap.
(For example, a Slave Unit that is set to node address 0 has 24 inputs and a Slave Unit that is set to
node address 1 has 16 inputs. In this case both Slave Units will be set to use the Input 1 Area.)
Note: As long as the allocated areas themselves are not duplicated between nodes, Slave Units set for different
node addresses can be allocated remote input registers (RWr) and remote output registers (RWw) in the
same node address area.
(For example, a Slave Unit set for node address 1 can be allocated 16 outputs in the Output 1 Area, while an
Expansion Slave Unit set for node address 0 can be allocated 16 inputs in the Input 1 Area.)
• A Slave Unit was removed and then a Slave Unit of a different type started participating at the same
node address.
• CompoNet communications become unstable.
Illegal Configuration Error
If the permitted number of Repeater Unit segments is exceeded, the NS indicator on the front of the
Gateway Unit will flash red and the seven-segment display will show “E5.”

4-2-6 Data Allocations for Word Slave Units
Memory is allocated to Word Slave Units in units of 16 bits (1 word).
Slave Units requiring fewer than 16 bits are sill allocated one word per node (the allocation for the set
node address). (See note.)
Note: Even 8-point Slave Units are allocated 1 word. The bits are allocated in the lower byte and the upper byte is
not used.
Slave Units requiring more than 16 bits and 32 bits or less are allocated two words per node (the allocation for the set node address and the next node address).
In the same way, multiple words are allocated to other Slave Units according to the I/O capacity of the
Slave Unit (including the word for the allocated node address and following words).

• I/O Allocations when Expansion Units Are Used
Memory is allocated to a Basic Unit with an Expansion Unit in the same way as it would be allocated to a Slave Unit of the same size as the combination of the sizes of the Basic Unit and the
Remote Input Registers (RWr) and remote output registers (RWw) of the Expansion Unit.
The following examples show the allocations when an Expansion Unit is connected to a Basic Unit
at node address m (m = 0, 1, 2,...).
Additional Information
For Slave Units with both inputs and outputs*1, the remote input register (RWr) node
address is used as the Slave Unit node address. Therefore, the Participation Flag and
Communications Error Flag correspond to the bits for the remote input register (RWr)
node address.
*1:A Word Slave that combines a Basic Unit and Expansion Unit to provide both inputs and
outputs, or a CRT1B-MD Bit Slave, which provides both inputs and outputs.

4-2-7 Data Allocations for Bit Slave Units
Bit Slave Units are allocated data in units of two bits (two points).
For example, eight Slave Units with two points each would be allocated one word. Likewise, four Slave
Units with two points each and two Slave Units with four points each would be allocated one word.
A Slave Unit with two points is allocated two bits in the node address area for the node address set for
the Unit.
A Slave Unit with four points is allocated four bits, two bits in the node address area for the node
address set for the Unit and two bits in the next node address area.

This section describes how to handle errors that may occur in the CompoNet network.
5-1-1 CompoNet Network Errors
This section describes the meanings of the indicators and seven-segment display when errors occur in
the CompoNet network. It also provides countermeasures for handling the errors.
5
Meanings of Gateway Unit Indicators and Procedure for Handling
Errors
If an error occurs, the general location of the error is shown by the status of the indicators.
With the Gateway Unit, in addition to these indicators, a seven-segment display shows the location and
content of errors.
5-1-2 Troubleshooting Sequence When an Error Occurs
1. Determine the general location of the error.
Check the pattern in which the indicators are lit to determine whether the error occurred in the Gateway Unit or in the network.
↓
2. Determine the details.
Check the seven-segment display and the remote inputs (RX) in the Status Area to determine the
location and content of the error.
5-1 Troubleshooting CompoNet Network Errors
3. Determine the cause of the error.
Consider the onsite conditions in relation to the circumstances of the error, and determine and
remove the cause of the error.
4. Take countermeasures.
Check the system status in the Unit operation after error detection column, check the required operations in the Countermeasures column, and restore system operation to normal.

Probable cause of
error
A Slave Unit
disconnection was
detected.
An address duplication
error was detected for a
Slave Unit attempting to
participate. Or, an error
was detected in Slave
Unit communications.
It was detected that the
Slave Units and
Repeater Units
requesting to participate
in the network exceeded
the permitted number of
Repeater Unit segments
(two).
It was detected that a
Slave Unit registered in
the registration table is
not participating within a
fixed time after power is
turned ON to the
Gateway Unit.
Participation of an
unregistered Slave Unit
was detected.
Unit operation after error
detection
System operations continue.
Participation of the
disconnected Slave Unit is
awaited.
When the cause of the error
is removed, normal operation
is restored. (The NS indicator
lights green.)
The duplication error is
registered in the error history.
System operations continue.
Subsequent Slave Unit
participation is prohibited
from the point where it is
detected that the permitted
number of Repeater Unit
segments has been
exceeded in the participation
processing.
Other system operations
continue.
After normal status is
restored, the Unit recovers
when it is restarted.
System operations continue,
and remote I/O operations
start. Participation of the
Slave Unit where the error
occurred continues to be
monitored. When Slave Unit
participation is completed,
normal status is restored.
(The NS indicator lights
green.)
All other system operations
continue without allowing the
participation of the
unregistered Slave Unit.
Recovery is attained by
restoring normal status and
restarting the Unit.
Countermeasures
Either of the following may be the cause
of the error.
1. Communications had to be
continually retried for the applicable
Slave Unit due to noise, until the
specified number of retries was
exceeded.
2. Responses to communications from
the Gateway Unit are not possible
because of a malfunction, line
disconnection, or communications
power supply interruption at the
Slave Unit itself.
Inspect the Slave Unit where the
disconnection was detected, and remove
the cause of the error. There is no need to
restart the Gateway Unit.
A Slave Unit or Repeater Unit in the same
network is set for the same node.
Use the following procedure:
1. Turn OFF the power to the Gateway
Unit and the Slave Unit.
2. Change the duplicate node number
to the correct value.
3. Turn ON the power to the Gateway
Unit and the Slave Unit.
If the error persists, it is safe to assume
that a communications error caused the
problem. Check for noise entering the
network, disconnected cables, and loose
connectors or signal wires, and make
sure the network is installed according to
specifications.
The maximum number of Repeater Unit
segments is registered to two in the
Gateway Unit and cannot be changed.
This error thus indicates that there are
three or more Repeater Unit segments.
Correct the wiring and restart the
Gateway Unit.
If the error does not clear, check the Slave
Unit that is not participating.
Check and correct the status of the
unregistered Slave Unit, and then restart
the Gateway Unit.
