Conformance

Q.1Where can I get the test specifications and test request sheet?
A.1
  • Regular members and above can obtain conformance test specifications and a test request sheet.
    You can download them from the Members Site in the CLPA website for free.

Q.2What is a vendor code?
A.2
  • From the 10 digit member ID, the 5th to 8th digit is the vendor code. If the member ID is 123-456-7890, "5678" will be the vendor code.

Q.3Do I need to conduct a conformance test for those products using certified network card (modules) from a third party when manufacturing/selling them?
A.3
  • Yes, because the module only provides the connection to the network and it is also necessary to check that the overall product functions correctly on the network.

Q.4What is the fee for conducting conformance tests?
A.4
  • Conformance test fees will differ depending on member category, network type and product category. Please click here for details.

Q.5Is it necessary to take the conformance test again if a communication module that can be embedded in multiple devices is sold in combination with a device other than the combination that has been certified by the conformance test?
A.5
  • Yes, because the module only provides the connection to the network and it is also necessary to check that the overall product functions correctly on the network. While a certification may already have been obtained, the new product may have a different operation to the one which was previously certified.

Q.6If the certified hardware is used for the communication interface part, but the firmware version changes, is it necessary to re-conduct the conformance test of the software part?
A.6
  • If the software related to the communication interface is changed, you need to take the conformance test again. This is because we need to check that the new firmware still allows correct communication functions.

Q.7How do I conduct a test for CC-Link IE Field Basic?
A.7
  • For CC-Link IE Field Network Basic, you can do the test yourself, using a CLPA software tool.
    Click here for more details.

  • [Conformance test flow for CC-Link IE Field Network Basic]

    1.Please conduct a self test using the CC-Link IE Field Network Basic conformance test tool.

    2.Please send your test result (CSV file output) to CLPA after testing.You must be a Regular member or above to obtain the tool.

    3. CLPA will check the test result and inform you of the result.

    4.If successful, a certificate is issued.
    After we confirm the test was successful, a certificate will be issued, usually within about a week, depending on workload.

Q.8For the conformance tests, the creation of a CSP+ file is essential. How do I create this?
A.8
  • You can easily create this using the "CSP+ Profile Creation Support Tool". Also see the "(CSP+) Creation Guidelines". Both documents can be downloaded from the CLPA website.

Q.9When the specified parts (crystal oscillator, etc.) of a dedicated communication LSI (MFP3N, etc.) are discontinued and replaced by the manufacturer's recommended alternative, is it necessary to retake the conformance test?
A.9
  • Please retake the conformance test when you change the specified parts to an alternative one.
    For example, when changing the crystal oscillator, please conduct the "noise test" of the "manufacturer's test" at your company and submit the "request form" and the "manufacturer's test result".
    If there is no problem with the "manufacturer's test result", we will check it and certify it based on your result.

Network Technology

CC-Link

Q.1What are CC-Link's recommended components?
A.1
  • These are the recommended components:

  • Filter

    RS485 transceiver

    Zener diode

    Photocoupler (for signal line)

    Photocoupler (for gate control)

    Digital isolator (for signal line and gate control)

    For details of recommended components, please refer to the CC-Link Specification-Implementation.

    Parts other than the above, such as the crystal oscillator designated by Mitsubishi Electric's CC-Link dedicated CLPA.
    Please contact the relevant suppliers for alternative parts if the designated items are no longer available.

Q.2What is the difference between CC-Link Version 1.00, 1.10 and Version 2.00?
A.2
  • Ver. 1.10 has a minimum inter-station cable length of 20 cm and improved wiring due to changes in device and cable specifications.Ver. 2.00 expands the amount of data per system and station by up to 8 times.Please refer to "CC-Link Version Description". Click here for details.
    For installation guidance, please refer to the "CC-Link Installation Manual".You can download them from the CLPA website for free.

Q.3Where can I download the manual for the NFP3N CC-Link chip?
A.3
  • MFP3N is a product of Mitsubishi Electric Corporation, and the manual is not available from the CLPA. Please contact your local supplier.

Q.4When configuring a CC-Link network, some devices may only support Version 2.00. Can these be combined with Version 1.00 devices?
A.4
  • In Version 2.00 mode, devices compatible with Version 2.00 and Version 1.00 can be used together.In Version 2.00 mode, the master unit must be a Version 2.00 compatible master unit (RJ61BT11, QJ61BT11N, etc.).
    For installation guidance, please refer to the "CC-Link Installation Manual".You can download them from the CLPA website for free.

Q.5Does using a repeater limit the communication speed of a CC-Link network to less than 10Mbps?
A.5
  • When using a repeater, keep the communication speed at 2.5Mbps.For installation guidance, please refer to the "CC-Link Installation Manual".You can download them from the CLPA website for free.

CC-Link IE Field Basic

Q.6Can CC-Link IE Field Basic and CC-Link IE Field be connected?
A.6
  • This is not possible as they use a different communication protocol.

Q.7There are products that support CC-Link IE Field Basic and have two Ethernet ports. Is it possible to connect in line topology with these devices?
A.7
  • CC-Link IE Field Basic is designed to support line topology in addition to star topology, however supporting topologies could differ depending on each manufacturer's device specifications.
    For details, please contact the manufacturer.

CC-Link IE Field

Q.8If you install the "CC-Link IE Field Network Basic WireShark Plugin", is it possible to acquire CC-Link IE Field Network communication data?
A.8
  • The plugin allows the communication data to be captured, but not analyzed.Note that currently there are plugins for CC-Link IE Field Basic and CC-Link IE TSN, but not CC-Link IE Field.

Q.9The CC-Link IE Field communication speed is 1Gbps. What is the network update time? How much does it depend on the number of I/O points on the network?
A.9
  • The time will depend on the network configuration. As an example, if there are 128 RW/RY devices and 64 RWw/RWr devices per station, then the network update time is 2.22 msec when 32 stations are connected in standard mode and 6.25 msec when 120 stations are connected.

Q.10The CC-Link IE Field specification states that the maximum distance between stations is 100m.Is it possible to extend it with an Ethernet switch?
A.10
  • The maximum distance can be extended using Ethernet switches and media converters.
    For transmission characteristics, etc., please refer to the "CC-Link IE Field Installation Manual".You can download it from the CLPA website for free.

CC-Link IE TSN

Q.11Does the "model type" ID information in the CC-Link IE TSN system have common profile specification (device vendor independent)?
