    The CC-Link system on a machine has been intermittently dropping out.  Normally the Link Scan Time runs at a solid 87ms.  When the system "drops out", the link scan time will increase.  Sometimes double, triple, or go up 10x. It happens when the machine is running or when it sits idle.

    There are 33 stations on the network.  The same stations do not always fault but sometimes all of the stations will fault at once (as seen in the attachment pictures.)

    We have changed the main QJ61BT11N, the processor, the Q62N power supply, the main backplane (base unit), all cards on the main backplane. 

    Is it possible for one station or one of the cables to create a network wide problem?  Any ideas thrown at us would be appreciated.

    I installed and commissioned a multi arm rotational machine cc- link ran to the five arms with 3 stations/arm cc-link ran through a set of slip rings I used a FX 3U and have not had a problem yet in 3 years continuous running. I would look at the cabling as a first port of call. Good luck.

    My problem appears to be fixed after I deleted plc data and reinstalled my software. I'm now able to write to plc and reset it, the Error LED turned off. I hope it won't come back:-)

    @Cetronic, no problem!  I have to thank you for being intressed in my post. I'm here to learn from you about mitsubishi PLCs!

    @Copyleft, thank you for having mentioned eManual Viewer. I was expecting something like that in order to make use of all of those manuals.

    To answer your questions :

    1. RTFM (to me is) : Read Safety related informations -> Read Installation and Wiring Guides ->  Quick Start <-> Troubleshooting 
    • When I connot find a direct connection between Quick Start and Troubleshooting, I feel missing something. For example , I couldn't make use of this warning message...mismatch.JPG.390fdf8db8b175c29e0db9a8475
    • I don't think the following Diagnostics(CPU) is really helpfull, since the only proposed corrective is "Write the project again". I'm used to jump from Error Code to details and corrections.

    2. Is this a brand new? Yeah, it is!5deefa4fe1044_IMG_20191209_2028595381.th

    ".... you even don’t know the Mitsubishi series nomenclature ...."

    When I was in college back in 2008, I bought this book of John Ridley and helped me a lot. Even if I didn't have access to the actually hardware, I used the content on hardwares within my reach....

    I too have used John Ridley's book as a reference. The one issue I had related to an FX5 was the wrong version GXWorks2 and once updated I had to write a new project with the correct Eth Settings this probably not your issue. I don't have access to hardware and use GX works2 and IEC Developer.

    i cut my teeth on Siemens S5 up to 155U hardware and associated components. I actually found the ability to write S5 Machine Language and function block capability much more versatile but hardware reliability the same. Mits is much more accepted and understood by maintenance staff.

    What's the " Comms failure on a FX1 due to Technician error " you're talking about? And why you believe this "has virtually been eliminated on the latest models" ? I'm not talking about what you "believe", I'm talking about what you KNOW AS FACTS on FX5 series! So I will decide wether or not to switch on those models. If you don't know, please don't insult.

     

     @Yams I apologise if you took the comment "Stupid is as Stupid does" referred to you. I was referring to the technician who powered his laptop from a different phase to the supply to the PLC and the refered voltage difference damaged the Comms circuits. I know that from the FX3 onwards this Comms port issue does not occur as I have used a number of FX3 and FX5 with CCLink to AB drives with no problem. 

    I agree with Copyleft your Mitsubishi representative would be a good starting point to enable a decision. I hope you are getting a good response to your questions. Please let us know how you resolve the error.

    I tried to initialize my FX5U as you described, unfortunately it didn't work out. The Error LED started blinking over and over as finished initialization. 
    I'm just experimenting the FX5 series beside my daily works, can somebody tell me those plc are really reliable when compared to Siemens or AB? 

    GX works3 diagnostics tell you there's an error, but doesn't tell you clearly how to fix it...the messages are misleading, and the manuals are bulky as bible...

    I have used all of the Plc,s mentioned and a lot of Mits FX, FX1, FX2 FX3 and FX5 and can only remember a Comms failure on a FX1 due to Technician error and a believe this has virtually been eliminated on the latest models, however stupid is as stupid does. As always I believe the manual is the key. Good luck and continue to post if you have specific questions.

    Hi!

    Is there anyone who knows where to get a PID function block for the FX3G series PLC?

    BR,

    Jim

    I have used the PidFX_V300 library in GXWorks2 In the the FX3U FX3G and the FX3GE I am sure its available on the Mits Euro Site or it might be the Beijer site. There are various versions of Pid.

    Hi Dunc,

    I had the exact same problem, check the hardware version of the FX3U it has to be above a specific version to recognise the ENET-ADP (l/h side). The version number is in the manual and FX3U should be above 3.1 or you will need to use the FX3U-ENET on the r/h bus.

    Hi, I have a job to upgrade a panel I did a long time ago.

     

    The panel already has a FX1n plc and 4 standalone temperature controllers.

    The plc controls the batching and mixing and the temperature controllers - control the temperature.

    They now want different actions at different temperatures and so I have ordered an FX2n-TC add-on for the plc.

    My question - can I piggyback the wires from the pt100 themocouples at the temperature controller terminals into the fx2n-tc

    or do I have to wire extra wires to the thermocouples and make sure the tc's are the double type.

     

     

    PT 100 and TC or thermocouple are two different items. TC can be piggy backed and As Nightfly points out you can't piggy back RTD (PT100) Some controllers can re-transmit.

    Richard?

    from experience most of these type machines have different setup parameters, my suspicion is that there have been changes given that the ROM has been removed. Can you confirm FX model? The ROM would have been the Manufacturers base program. Is it dancerbar/tension control?

    Hi Steve this complete package was purchased by the business some more than a year ago and icludes all cable harnesses, PLC, PC and Software (PLC Code and HMI Interface). I would believe that any upgrade now would be to the RX3I as the 90-30 moves to Mature state. We have had discussions withe local agent. Not sure if ferry have upgraded there Code to the RX3I on these old machines.

    Thanks Crossbow, Ferry Industries are situated in Stow, Ohio and are big in this area and the upgrade is from Tenor to GE Fanuc 90-30 and that is my recomendation to the client and will require the Ferry Technicion, all the upgrade equipment is already there, just the knowhow of what is required.

    Can anyone direct me to Info on a Tenor 100-6-9002 ?? Any help would be appreciated, This unit is on a second hand Ferry Machine and which comes complete with an Upgrade package, PC, Screen and Fanuc 90-30 PLC. Client is trying to make a decision on upgrade.

    I use GXworks2, Panasonic FXwin Pro and Codesys and have a number of projects using these which are IEC compliant and I can assure you it is generally not possible to cross use. The closest I ever got was ABB Codesys to Klockner Mueller equivilent, about 60% import.

    I had a similar situation with the master and 8 ABB ACS 500 drives as long as all drives were active comms was okay if 1 drive was switched off comms was hit and miss to continue. Left all drives on and no problem, never did solve it. I was using IEC Developer and GX Configurator DP Sorry dont rember version numbers.

    Thanks kaare_t the cable I was using at the time was an SC-03 as I remember (Number of years ago) Using SC-09 now and NEVER connect the shield wire. My reason for the comment was that PROG-E was the exact error with an FX1N and Mits Aust wanted about the price of a new unit for repair.
