6-1 Applicable Directives

•EMC Directives

6-2 Concepts

EMC Directives
The OMRON products are electric components that usually are used after being built in other machinery or manufacturing equipment. They are designed to conform to the relevant EMC Directives. This will facilitate the compliance of the final machinery or apparatus to such directives. However, the installation and configuration of such machinery and apparatus in which the OMRON products are mounted and used will differ according to their characteristics. Thus it is virtually impossible for OMRON to ensure the conformity of an entire system to the relevant EMC Directives. The users must conduct the necessary tests and ensure the conformity of the system as a whole.
The relevant EMC Directives are: EN 61131-2 and EN 61000-6-2 for EMS, i.e., Electromagnetic susceptibility,
EN 61131-2 and EN 61000-6-4 for EMI, i.e., Electromagnetic Interference, and EN61000-6-4 for Radiated emission, 10-m regulations, among EMC (Electro-Magnetic Compatibility).

6-3 Conformity

1,2,3... 1. The OMRON product must be installed in a control panel.
The OMRON products in this manual comply with the relevant EMC Directives. To ensure that the machinery or apparatus in which the OMRON products are used complies with the EC Directiv es , the user m ust follow these instructions:
2. DC power supply unit as well as DC power connected to I/O Units must have reinforced insulation or double insulation.
3. Compliance to the EC Directives means conformity to the Emission Standards (EN 61000-6-4). Radiated emission characteristics (10-m regulations) may vary, however, depending on the configuration of the control panel used, the compatibility with other devices connected to the control panel, the effects of wiring and other conditions. The user must confirm that the overall machine or equipment complies with the EC Directives.

Overview of the CompoNet Network Section 1-1

1-1 Overview of the CompoNet Network

CompoNet is a field network designed for communications between the input and output components on the shop floor and a personal computer (or PC) or a PLC. CompoNet requires less wiring labor but provides high maintainability.
The PC and the CompoNet Slave Unit exchange input and/or output data cyclically through a CompoNet Master Board.
By using explicit messages, users can read data from the CompoNet Slave Unit or write data into it.
High-Speed Communications of Multiple Nodes
Terminating Resistor
Slave Unit
Repeater Unit
Slave Unit
CompoNet Master Board
Terminating Resistor

Here are the main featur es of CompoNet:
CompoNet can provide remote I/O communications for multiple nodes as many as maximum 2,560 points in a high speed such as 1000 points per millisecond when the data rate is 4 Mbps*. This allows integration of conventional system configuration with basic I/O Units into a CompoNet network.
Greater Flexibility with Repeater Units
2
* The data rate of 4 Mbps does not support T-branch connection. Thus any
Slave Unit with pre-attached cables is not usable.
Repeater Units can expand a network installation in the following ways:
• Extending the Communications cable,
• Increasing the number of connected nodes,
• Creating a branch connection from the trunk line, and
• Converting cable types.
Repeater Units can be used to expand the trunk line for up to two layers. The lines downstream from the Repeater Units are called sub-trunk lines. The maximum number of connectable Repeater Units is 64 per Master Board and 32 per trunk line.
Note The power to the sub-trunk lines must be supplied from the Repeater Units.
Page 23
Overview of the CompoNet Master Board Section 1-2
Bit-Level Distribution CompoNet is connectable with industry-standard e-CON connectors and
Slave Units of clamp terminal-block type. They allow bit-level controls of conveyors or at warehouses where many sensors are placed over a wide range.
Data Exchange by Explicit Messages
Automatic Baud Rate Detection
Explicit messages are used to access from the PC to the Slave Units and Repeater Units connected to the CompoNet network. This feature facilitates the maintenance of the entire networ k.
By setting the baud rate on the CompoNet Master Board, the Slave Units automatically detect the baud rate of the CompoNet Master Board and follow it. There is no need to set the rate individually on the Slave Units.

1-2 Overview of the CompoNet Master Board

CompoNet Master Board is a board that has a mastering function to control inputs and outputs for the Slave Units connected to the CompoNet network. The Board is either compatible with PCI bus (Model # 3G8F7-CRM21) or with CompactPCI bus (Model # 3G8F8-CRM21).
Here are the main features of the CompoNet Master Board:
Control by API Functions In the Windows operation systems, all functions on the CompoNet Master
Board can be accessed by API functions.
Control by Shared memory Accesses
In operation systems other than Windows, the CompoNet Master Board is used via access to shared memory.
Flexible Allocation of the Number of Connectable Nodes
Registration Table Function to Control Participating Slave Units
Optimizing Communications Cycle
Synchronous and Asynchronous Access to I/O Data
Other Functions • Communicat ions Stop Due to Communications Error function
The number of connectable nodes can be set differently for each Word Input Slave Units, Word Output Slave Units, Bit Input Slave Units and Bit Output Slave Units.
This function is used to pre-register the node addresses and models of Slave Units that are to participate in the network, and to check whether a Slave Unit that is actually participating is registered or not. If the Slave Unit is not registered, it is not allowed to participate. The time can also be set to monitor duration from power-on until a registered Slave Unit actually participates. Remote I/O communications can be stopped until all registered Slave Units participate in the network, but it can be started only with all Slave Units participating. The latter function is called the All Registered Slave Participation Standby Mode.
When the Registration Table function is used, the communications cycle is optimized and fastened in accordance with the information in the table.
Both synchronous and asynchronous types of access are supported. Synchronous access maintains synchronicity for each node, while asynchronous access does not do that but instead provides faster access. In the latter case, I/O data keeps synchronicity only within the same word.

Mounting a Board Section 2-1

2-1 Mounting a Board

2-1-1 Confirmation

Before you mount a CompoNet Master Board on the PC, confirm the following:
Note CompoNet Master Boards support Windows Plug & Play.
Item Description
Unused PCI bus slot Be sure that the PC you will use has an unused PCI bus slot. Duplication of
interrupt requests (IRQ)
CompoNet Master Boards use IRQs. IRQ are automatically allocated for PCI bus. In a PC which mounts an ISA bus, an IRQ for PCI bus may overlaps with that for ISA bus. This prevents the PC from starting up. To avoid this, take one of the following measures and be sure the IRQ for PCI bus does not overlap with the IRQ that has been used by the ISA bus.
Call up the BIOS menu of the PC and set it not to use Plug &
Play.
Call up the BIOS menu of the PC, and on the setting step for
IRQ allocation for the PCI bus set the IRQ that has been used by ISA bus to “Reserved” to prevent automatic allocation.
Note
As for the procedures to call the BIOS menu and to set the allocation, see
the operation manual of the PC you are using.
You can confirm the IRQs that have been used by ISA bus in the following
procedure:
(1) Start up the PC that has no CompoNet Master Board mounted. (2) On the Star t menu of the Windows, select Start
from the pop-up menu. Doub le-clic k the System. Select the Hardw are Tab. Push the Device Manager button.
(3) D isplay the property of the ISA board whose IRQ is to be checked. Select
the Resource Tab and check the IRQ.

2-1-2 Setting the Board ID

A Board ID is the ID number given to a Board. By this number the PC identifies a Board among the multiple CompoNet Master Boards mounted on it.

3-1 Settings at Communications Cycle Startup

The function CPNT_StartCycle is used to start the communications cycles for the CompoNet Master Board from the user application. The function CPNT_StartCycle uses the data rate and the number of occupied nodes as arguments.
The command OPEN_SYSTEM is used to start the communications cycles through the shared memory access.
To enable the superior function and start the communications cycle, execute the function CPNT_StartCycleEx in Windows or the command OPEN_SYSTEMEX for shared memory access. See Section 3-5.

3-1-1 Settings Required for Starting the Communications Cycle

Function Description
Data rate This is used to set the data rate for a network.
The Slave Units in the same network automatically follow the data rate of the Master Board. Data rate is selective among 4 Mbps, 3 Mbps, 1.5 Mbps and
93.75 kbps.
Number of occupied nodes
The number of nodes can be set individually for Word IN Slave Units, Word OUT Slave Units, Bit IN Slave Units and Bit OUT Slave Units.
*1.Every 16 points of a Word IN Slave Unit or a Word OUT
Slave Unit occupies 1 node.
*2.Every 2 points of a Bit IN Slave Unit or a Bit OUT Slave Unit
occupies 1 node.
*3.Node addresses are allocated to Slave Units in ascending
order starting from #0. Unused addresses are also included in this allocation order. They cannot be skipped.
*4.Only the Slave Units in this set range are to participate. Not
all of the occupied areas are necessarily allocated by a Slave Unit.
Example: When a system consists of Slave Units as shown in the table below , the number of nodes occupied by each type of Slave Units are: 8 by Word IN Slave Units, 3 by Word OUT Slave Unit, (*3) 3 by Bit IN Slave Unit, 10 by Bit OUT Slave Units (*3)

3-2 Access to I/O Data

3-2-1 Allocation of I/O Data

In the CompoNet network system, the I/O data is allocated separately for Word IN Slave Units, Word OUT Slave Units, Bit IN Slave Units, and Bit OUT Slave Units. It is allocated in the shared memory of the CompoNet Master Board.
Allocation for W ord IN Slave Units and Word OUT Slave Units
• Every 16 points of a Word IN Slave Unit or a Word OUT Slave Unit occupies 1 word in allocation area. For example, a 32-point IN Slave Unit occupies 2 words in allocation area for Word IN Slave Units.
• The offset address that is allocated to the shared memo ry is deter mined by the node address.
• Word MIX Slave Units occupy the allocation areas for both of Word IN Slave Units and Word OUT Slave Units. For example, when a Word MIX Slave Units has 16 inputs and 64 outputs, it occupies 1 word in the allocation area for Word IN Slave Units and 4 words in the allocation area for Word OUT Slave Units.
• An 8-point Slave Unit also occupies 1 node or 1 word. It is allocated to the lower byte of the 1- word, while the upper byte remains open.

Note A single allocation area shall never be occupied by plural nodes. However, as
long as the same words are not allocated to more than one Unit, the Input Area and Output Area with numerically the same node address can be allocated to Slave Units with different node addresses. For example, OUT1 can be allocated to the 16 outputs for a Word OUT Slave Unit set for node address 1, and IN1can be allocated to the 16 inputs for a Word IN Slave Unit set for node address 1.

Precautions for Correct Use
When a Slave Unit occupies plural allocation areas, other Slave Units which have the occup ied node addresses cannot participate.
Example: When a Slave Unit with node address 0 exists in a network and it
occupies 2 words in the IN area and 4 words in OUT area, Word IN Slave Units whose node addr esses are 0 or 1, a nd Word OUT Slave Units whose node addresses are 0, 1, 2 or 3 cannot participate.

Every Bit Slave Unit occupies 2 point or 2 bits. For example, 8 sets of 2-point Slave Units occupy 1 word. In the same
manner, a combination of 4 sets of 2-point Slave Units, and 2 sets of 4-point Slave Units, occupies 1 word.
A 2-point Slave Unit occupies 2 bits as a node, which is for its own node address.
A 4-point Slave Unit occupies 4 bits as a node, which is for its own and for the next node addresses.

Precautions for Correct Use
When a Slave Unit occupies plural allocation areas, other Slave Units which have the occup ied node addresses cannot participate.
Example: When a Slave Unit with node address #0 exists in a network and it
occupies 2 bits in the Bit IN area and 4 bits in Bit OUT area, Bit IN Slave Unit whose node address is 0, and Bit OUT Slave Units whose node address is either 0 or 1 cannot participate.

3-2-2 Access to I/O Data

There are two methods for access to I/O data: synchronous and asynchronous.
Synchronous access Synchronous access uses access rights and ensures node-by-node
synchronicity. It requires a waiting time of maximum one communications cycle in order to
obtain an access right. See Section 4-1-2 for the access procedure.
Asynchronous access Asynchronous access does not use access rights. Thus it enables high speed
access to I/O data. This type of access, however, ensures the synchron icity of every 16 bits of I/O
data. See Section 4-1-1 for the access procedures.

3-3 Status

Status comprises two general categories: One is the Basic Status Group, which is constantly updated in the shared memory, while the other is the Detailed Status Group. The statuses in the latter group are read by the application whenever necessary. The PC application issues a read request to the CompoNet Master Board, and read the status.

3-3-1 Basic Status Group

To access to the Basic status group in the Windows operation systems, the function CPNT_GetStatus is used.
In an OS other than Windows, the status group can b e read dir ectly fro m the shared memory access.
35
Page 56
Status Section 3-3
Status Description
Participation flag When a Slave Unit participates in the network, the bit
corresponding to the node address will be on. Once the target Slave Unit is participating, the bit remains on. It
stays on even the Slave Unit separates due to a communications error.
Communications error flag
State Status It shows the entire network status and the CompoNet Master
The bit will be on if a communications error occurs to the once participated Slave Unit whose participation flag is on, and its communications with the CompoNet Master Board is prevented. The bit will be off when the error is resolved.
Board status. See Appendix B.3.3.
Precautions for Correct Use
For a Word Mixed Sla ve Unit, use the status for the node address of the Word Input Slave Unit. For a Bit Mixed Slave Unit, use the status for the node address of the Bit Input Slave Unit.

3-3-2 Detailed Status Group

To access to the detailed status group in the Windows operation systems, the functions CPNT_GetStatusEx is used.
To read the detailed status group from accessing the shared memory area, the command REQUEST_STATUS is used and a read request is issued.
See Appendix B.3.6 for the procedures.
Status Description
Duplication error flag
Registration error (Registered Slave not participating) flag
Registration error (Non- registered Slave participating) flag
Repeater configuration error

Precautions for Correct Use
For a Word Mixed Sla ve Unit, use the status for the node address of the Word Input Slave Unit. For a Bit Mixed Slave Unit, use the status for the node address of the Bit Input Slave Unit.
It stores the registration table example made from the information of the Slave Units currently participating.

3-4 Explicit Messages

Explicit messages are general-purpose messages specified by CompoNet protocol.
The messages are used to rewrite a Slave Unit parameter or to read out any data from a Slave Unit.
In the Windows operation systems, explicit messages are used by functions CPNT_SendExplicit, CPNT_PeekExplicit and CPNT_ReceiveExplicit.
To use the message by accessing the shared memory area, see Section 4-3.

3-5 Detailed Settings at Communications Cycle Startup

3-5-1 Registration Table Function

Outline This is the function used to register the model of a Slave Unit to par ticipate
along with the corresponding node address, and to check whether a Slave Unit that is actually participating is registered or not. It identifies any Slave Unit that is not on the list or wh ose allocated node address or mod el differs from the information on the list, and prevents it from participating in the network.
In the Windows operation systems, the function CPNT_StartCycleEx enables the Registration Table function. To access the shared memory area, the command OPEN_SYSTEMEX is used.

If the comparison finds out any non-conforming Slave Unit, the Registration Table comparison error occurrence flag (i.e., the Bit 01 of the StateStatus in the Basic status group) comes on.
When the All Registered Slave Participation Standby Mode (as described later) is then disabled, the remote I/O communications starts. If it is enabled, the remote I/O communications will not start.
Behavior Here is the behavior in each case.
• When all registered Slave Units participate within the Registered Slave Unit Participation Time *1 *2 after a power-on *3, the All Registered Sla v e Units participating flag, i.e., the bit 06 of the StateStatus in the Basic status group, comes on. If no non-registered Slave Unit par ticipates then, the Registration Table comparison error occurrence flag will be off.
• If any non-registered Slave Unit participates then, it is a registration error (a Non-registered Slave is participating), and the Registration Table comparison error occurrence flag comes on. At the same time, the NS indicator on the CompoNet Master Board flas hes re d.
• If not all of the registered Slave Unit participate within the Registered Slave Unit Par ticipation Time *1 *2 after a power-on *3, it is a registration error (Registered Slave in not participated), and the Registration Table comparison error occurrence flag comes on. At the same time, the NS indicator on the CompoNet Master Board flashes red. The Registration Table comparison error occurrence flag and the error indicati on turn off as soon as the applicable Slave Unit participates.
The model differs.

*1 The Registered Slave Unit Participation Time is disabled when the All
Registered Slave Participation Standby Mode (as described later), is enabled.
*2 In default, the Registered Slave Unit Participation Time is 30 seconds in
the data rate of 93.75 kbps, but it is 10 seconds in other data rates.
Page 59
Detailed Settings at Communications Cycle Startup Section 3-5
*3 When the I/O communications manual startup mode is used, it is not after
the power-on but after the remote I/O communications startup switch is started.
Setting the Registered Slave Unit Participation Time
All Registered Slave Participation Standby Mode
Communication Cycle Optimization Function
This is the time from when the communication cycles for CompoNet Master Board starts until when a registered Slave Unit is determined to have participated.
In default, the Registered Slave Unit Participation Time is 30 second in the data rate of 93.75 kbps but it is 10 seconds in other data rates. It can be set to an other time.
This setting is disabled when the All Registered Slave Participation Standby Mode is enabled.
In this mode, the remote I/O communications is stopped un til all the registere d Slave Units participate in the network, i.e., while the All Registered Slave Unit Participating Flag is off. The remote I/O communications starts once all of the registered Slave Unit participate, i.e., when the All Registered Slave Unit Participating Flag comes on. All Slave Units can participate in a lesser time than they do in normal mode or when this mode is disabled.
However, user must be aware that the remote I/O communications does not start unless all of the regis tered Slave Units participate.
While this mode is enabled, any settings (including the default of 10 seconds) based on the Registered Slave Unit Participation Time are disabled.
This function is used to disregard any unused comm unications parts based on the information on the Registration table, and to optimize the communications cycle.

3-5-2 Communications Stop Due to Communications Error Function

This function is used to stop entire communicatio ns, both I/O communications and explicit messages, when any one of participating Slave Units has a communications error. Then the Communications stop due to communications error occurrence flag, (i.e., the Bit 02 of the StateStatus in the Basic status group) comes on.
To recover the communications, the CompoNet Master Board must be reset. This function is enabled by the function CPNT_Star tCycleEx in the Windows
operation systems and by the command OPEN_SYSTEMEX for shared memory access.

3-5-3 I/O Communications Manual Startup Function

This function is used to manually start up the I/O communications. Slave Units can participate even while the I/O communications stop. The function is used when one wants to start exchanging I/O data explicitly
from the application. The function is enabled by the function CPNT_StartCycleEx in the Windows
operation systems and by the command OPEN_SYSTEMEX for shared memory access.
39
Page 60
Detailed Settings at Communications Cycle Startup Section 3-5
The I/O communications can be started by the function CPNT_ChangeToRunState in the Windows operation systems and by the command START_IOCYCLE for shared memory access.

3-5-4 IN Data Zero Clear Due to Communications Error Function

This function is used to clear (to ze ro) a ll t he input dat a or IN dat a of a ny IN or MIX Slave Units that have communications error.
When the IN Data Zero Clear Due to Communications Error mode is not selected, the input data or IN data of a Slave Unit that has a communications error is retained.
The function can restrain triggered behaviors due to a communications error in any systems where the "on" of IN data can be a trigger.
The function is enabled by the function CPNT_StartCycleEx in the Windows operation systems and by the command OPEN_SYSTEMEX for shared memory access.

5-1-2 Control of the Interrupt from PC to Board

Here is the procedure for the user application to interrupt the CompoNet Master Board.
Step Operation procedure Access to Shared Memory
1. Set the interrupt cause. (Generate an interrupt.)
2. Confirm the completion of interrupt process. (Confirm the Board completes the interrupt process.)
56
In the Interrupt T rigger register (0x0002), set a flag of interrupt cause to have into 1.
In the Interrupt Request Confirmation register (0x0003), confirm that the interrupt cause flag which was set to 1 in Step 1 turns to 0. (It remains 1 during interrupt but turns to 0 when the interrupt completes.)
Page 77
Basic Procedures Section 5-1

5-1-3 Control of the Interrupt from Board to PC

Here is the procedure by which to process interrupts from the CompoNet Master Board to the user application:
[Initial process] Before you start the communications (or you issue the command
OPEN_SYSTEM/OPEN_SYSTEMEX), set the Interrupt Mask (or select to notify the interrupt by causes or to confirm it by polling).
Step Operation procedure Access to Shared Memory
1. Set the Interrupt Mask. In the Interrupt Mask register (0x0004), set 1 to cause an
interrupt, or set 0 not to cause it.
[Process when an interrupt is made] When an interrupt is made, you can confirm the interrupt cause and clear the
cause.
Step Operation procedure Access to Shared Memory
1. Confirm the interrupt cause.
2. Clear the interrupt cause. In the Interrupt Clear register (0x0006), set the flags
In the Interrupt Cause Indication register (0x0005), confirm the interrupt cause.
corresponding to the generated interrupt causes into 1, and clear the causes. When all interrupt causes are cleared, the interrupt itself is cleared.
[Process to confirm the interrupt cause by polling] Confirm the interrupt causes periodically. Set the bits in the Interrupt Mask corr espondin g to t he causes t o be con firmed
by the polling into 0.
Step Operation procedure Access to Shared Memory
1. Confirm the interrupt causes periodically.
2. Clear the interrupt causes after confirming them.
In the Interrupt Cause Indication register (0x0005), confirm the interrupt cause periodically.
In the Interrupt Clear register (0x0006), set the flag corresponding to the generated interrupt causes into 1, and clear the causes.

5-2 Communications Cycle Control Procedures

5-2-1 Outline of the Communications Cycle

CompoNet communications cycles inv olv e exchanges of I/O data and Events. The state where only Events are exchanged without any transactions of I/O
data is called the IDLE state (or the state where I/O communications is stopped and in idle). The state where both I/O data and Events are exchanged is called the RUN state (or the state where I/O communications is running.) The phrase "Communications Cycle Operation" is the general term where the communication is perfor med in either the IDLE state or the RUN state.
Operation of the CompoNet Master Board makes the state transition as illustrated in below. When you execute the command OPEN_SYSTEM or OPEN_SYSTEMEX, the Board turns from the initial state to the IDLE state, and after some time it changes to the RUN state automatically. (The IDLE state is provided for a certain duration after the Board recognize the Slave Units so that the participation of Slave Units is facilitated.)

5-3 Setting the Time Information

CompoNet Master Board can save the error occurrence time at the same time when it saves the error log in its internal nonvolatile memory. To keep the correct time, the time inf ormation must be notified from the user application to the Board periodically. The time information can be written at any time.

5-4 Implementing the Reset Request

To use the Reset service of Identity Objects, a logic must be programmed so that the user application can reset the Board after the CompoNet Master Board requests a reset. (The logic is not required if you do not use the Reset service of Identity Objects.)

LED Indications and Error Handling Section 6-1

6-1 LED Indications and Error Handling

CompoNet Master Board has two LED indicators: MS LED for Board status and NS LED for network status. They indicate an error occurrence and the error content.
This section explains the LED indicators and how to handle the errors. The explanation assumes that the CompoNet Master Board has been set up properly.

6-1-1 Identifying Errors

An error is identified in the following sequence:
1. Knowing the error Monitor the lightning pattern of the LED Indicators. Know whether the error
is on the CompoNet Master Board (MS LED) or the Network (NS LED).
2. Identifying the error content Read the Basic status group and the Detailed status group in the
CompoNet Master Board. Identify the error location and the content. In the Windows operation systems, use the API functions to read the status groups. In other environments, access to the Shared memory area.
3. Detecting the error cause Compare the Error occurrence factors an d the on-site situation. Detect and
eliminate the cause.
4. Solving the error. Confirm the system state on the Board operation after detecting an error
and the required operation for solving the error on the Action to be taken. Reset the system operation to normal.
68
The subsequent sections explain the error identifying function on the CompoNet Master Board, the operation after detecting an error and the actions to be taken.

6-1-4 Error Identification by StateStatus

The errors monitored by NS Indicator lighting or flashing are identifiable by StateStatus of the Basic status group.
In the Windows operation systems, use the function CPNT_GetStatus to access the Basic status group.
In other environment, access to the shared memory area directly.

Identify the erroneous Slave or Repeater Unit by the Duplication error flag of Detailed status group. Note : This error occurs not only due to a duplication but also when a Slave Unit stops because of unstable communications. If the address duplication is not the cause, check the wiring or the terminators around the erroneous Slave Unit.
Identify the erroneous Slave or Repeater Unit by the Communications error flag of the Basic status group.
Identify the erroneous Slave Unit by the Registration error (Registered Slave not participating) flag or the Registration error (Non-registered Slave participating) flag in the Detailed status group.
Identify the erroneous Slave Unit by the Node causing a communications stop of the Master status in the Detailed status group.

6-2 Error Log

The Error log keeps record of the errors and occurrence time when the CompoNet Master Board detects an error. The records (or error log) can be read or cleared by the Detailed status group.

6-2-1 Error Log Table

Error Log Table Errors are saved in the Error Log Table in the CompoNet Master Board RAM.
One error is counted as one record in the tabl e . A maximum of 64 records can be saved. When the table is full with 64 records, the oldest error record is discarded to replace it with the next coming error.
The Error Log Table saves the following information:
• Error code,
• Detailed code, and
• Date when the error occurred (this data uses the time information notified by the user application)
70
Page 91
Error Log Section 6-2
Error Log Saving Area When an error is detected, it is saved, along with the time when the error
occurred, as an error in the CompoNet Master Board RAM. Some errors are fatal and they are also saved in the EEPROM. Those error
logs saved in the EEPROM are retained even after the CompoNet Master Board is shutdown or reset. The logs in the EEPROM are copied in the RAM, when the CompoNet Master Board is started up. The logs in the EEPROM are co pied in t he RAM, wh en th e Comp oNet Ma ster Board is started up.
It is only the error logs in RAM that can be read by reading function . But the error logs both in RAM and in the EEPROM are cleared by clearing function.
Reading or Clearing the
The Error Log Tables can be read or cleared by the Detailed status group.
Error Log Table
Precautions for Correct Use
To keep the time of error occurrence, the Board uses the time information notified periodically by the user application. When no time information is given by the user application, 0 is entered as the time of error occurrence in the error log.
