Hi PLC man, If I remember right: Wasn't it [F8] instead of [8] to get to the special function section? Best regards, Theo V.

microiuhvietduc, I suggest you contact your local Mitsubishi distributor for a licence key since this is not freeware.   Best regards, Theo V.

Hello KCRP, If you exchange your output Y040 for a retentive Marker (auxilery relay) you can use this marker in the next row to activate the output Y040. (see simple example below) For example, in the FX1 and FX2 series the retentive auxilery relay range starts from M384 and higher to keep the state after power fail. To have a complete overview of the range check the manual from you FX3u PLC. I've attached a part of te manual so you can see the M range, Timer range and counter range that is retentive and saves the value in the EEPROM of the PLC. Keep in mind that motors can start automatically without any warning if Y040 starts a motor. It can be a very dangerous situation!! I use this construction very often and always put a timer that acivates a sounder for 5 seconds to warn the operator that the machine will start up after the timer has expired and they can take their hands out of the machine in time or press the emergency stop before the output of the motor is activated. SIMPLE EXAMPLE: |--| |----(M384)   X0 (your start condtions for Y040) |--| |--(Y040) M384 (retentive M) You can also use a SET M384/RST M384 Best regards, Theo V.  

Hello Amogh,   First of all, why do you want to speed up? 9600BAUD is normally fast enough to feed the data to your Scada unless you have a lot of data to transfer from the PLC. If you want to increase the speed I suggest you use an Ethernet connection instead. As far as I know serial connection is limited to 9600Baud for FX PLC's. (Add a ENET-ADP adapter and an Ethernet module to the FX3G base module).   Best regards, Theo V.

Hi David,   See the attached picture with an example to set CH1 to 0-10Volt. Did you check the manual in the tutorial section? See reply from february 22th 2016 above for the details and also I can recommend you to check out the workshop pdf file. Aldough it is in Dutch the pictures taken from GX-Works2 are in English. Succes!   Best regards, Theo V.

Hi Russ333, You can extend a RS422 line up to 1200 meters so the 30m should not be a problem. Best regards, Theo V.

Hello Kumarsaurab92, As Andrei says in FX it is the ALT instruction to alternate on and off with the same input. You can use a rising edge puls PLS and a falling puls PLF to trigger the ALT instruction to make sure it is only triggert one time.   Best regards, Theo V.

Hello Mazen_abs,   At least you need the GX-Works or IQ Works software to download. I'm not sure if the FX5U has a build in webserver. In the FX3 series there is. Just type in the IP number of the FX5U in your internet explorer tot test. To connect make sure your laptopp/PC networkcard is in the same IP range and subnetmask as the FX5U. Modern laptops from Dell and HP can handle straight and cross RJ45 cables. If you are not sure just put a simple ethernetswitch in between the computer and the PLC. Than you have straight cable connections only.   Best regards, Theo V.

Ron S, And remember... Google is your friend to find manuals too! Regards, Theo V.

Hello Mazen_abs, See the link to the e700 manual. Chapter 4 is about the control trough a FL communication cable. It seems that this is a RJ45 plug. There is no wire diagram that tells specific the serial RS485 connection of the FL communication. I have only little experience with the Mitsubishi frequency inverters so this is all I can do for you in this.

Hello Irfan ali,   Check out this link to the manual of this TC module. http://www.999mitsubishi.com/media/downloadable/pdf/FX2N-4AD-TC%20usermanual.pdf To select a thermocouple type you need to set a buffer #BFM0 (see attached JPG) I hope this information helps you out, I'm not fammiliar with this TC module so no further information available from my side. Best regards, Theo V.

Hi Asad Hussain, November 11th 2016 there was a topic about installing the USB driver. You can read this topic with the link: http://forums.mrplc.com/index.php?/topic/31727-driver-for-cable-fx-ubs-aw/#comment-148864 Best regards, Theo V.

Hi Smithers1, I never opened a 8-pin plug but usually the order is from top to bottom in the list so I asume you are right about the order brown = pin 1 etc. I suggest that if you start testing the cable the first time just leave the white wire +5Vdc power not connected but use an external powersource for the GOT 5Vdc. Only connect the '-' from the 5Vdc to both GOT and PLC side (to close the loop). Aldough I think the port is galvanic isolated by opto-couplers you don't have the risk of destroying your FX PLC port due a wrong wire connection. As you noticed, there is not much info on the net about this subject. Perhaps because the original cable is around € 20,- euro and only the real hardcore electronic guys heat up the soldering iron to make a cable theirselfs just because it is possible... Don't take that personal but for that price I would just order a standard cable somewhere and save me the headache. It is up to you to decide. Succes!   Best regards, Theo V.

Hi Smithers1, Check-out the GOT connection manual: http://www.koningenhartman.nl/UserFiles/Product/Datasheet/GT1000%20Serie%20Connection%20Manual.pdf Page 186 gives some diagrams for GOT 1000 series. You can give it a shot ot try it on the GT2104. (See attached picture)   Best regards, Theo V.

http://store.plccables.com/Mitsubishi--USB-SC09_p_17.html Hi Kdog, With the link above you see a SC09-USB version (not an Original Mitsubishi) for USD $49,- For that amount of money you could take a chance. I use a serial to USB converter from a brand named 'Targus' in combination with a Original SC-09 cable (the red one) and this combination did not let me down so far on FX and A series CPU. https://www.bing.com/images/search?q=targus+usb+converter&view=detailv2&&id=58F75B66E7FF19CA15DF637035EB2369A00FDB20&selectedIndex=0&ccid=uUHPh7KZ&simid=607993291104127034&thid=OIP.Mb941cf87b2996a5637e06b4bd964cc1bo0&ajaxhist=0 Best regards, Theo V.

Hi Dynamicboy, Attached a wirering diagram for 4-20mA at a FX2N-4AD module. Also a programming example how to make an average reading if you signal is fluctuating too much. Aldough I think you might pick up some noise in the wires. If you have a loop generator in your workshop you can simulate a 4-20mA signal at the input of the PLC to see if the problem is present inside the PLC module or programming or if the problem is inside the Hanna transmitter.   Best regards, Theo V.

Hello Salama,   At least tell us some more details like the type of PLC and which diagram you need. Wirering in- and outputs or the internal electronics inside the PLC. (this last part I don't expect to be available) Did you check out the download section in this forum? many manuals are there to download.   Best regards, Theo V.

Thank you Bryll for the link, I will try this program after the holidays on a E1032 panel.   Best regards, Theo V.

Hi Bryll, Just a quick question at the side. I did the remote procedure as you described above in a E1032 panel before and used VNC to view the actual screen at the HMI. One problem that I had was to switch to an other screen. I could only view the actual screen but not operate functionkeys to switch to an other screen or change a value. I had to ask the operator at the remote side to switch manually between screens to look and view what was happening with the procesvalues inside the machine on location. Do you know a trick to operate the HMI buttons from the remote side using VNC or is it just a viewer only? I hope that you or one of the other forummembers have this experience.   Best regards, Theo V.

Hi Ssjophus, Also take in acount that the Medoc MS-DOS based software doesn't t work with Windows versions higher than XP! (You need an old PC/laptop) If you need to make an upload I suggest  as Kaare_t says and use a SC09 cable or a FX-USB-AW as an interface to your computer.   best regards, Theo V.

Hi Zubair Malik, You can't just overwrite the existing program inside the PLC? Best regards, Theo V.

Hi Daniel,   Check out this You tube instruction video to learn more about this USB driver installation. https://www.youtube.com/watch?v=gSDtxJ0pdpA You need to install the driver from the following directory: C:\Program Files\MELSEC\Easysocket\USBDrivers if you did a standard installation of GX-Works2. Best regards, Theo V.  

Hi Jds,   Are you sure the FX-32 type is right? If so, you also need a special programming adapter (if still available?). If it is a FX0(s)/FX1(s) or FX1N/FX2N model you need GX-Developer (part of GX-Works2 or IQ-Works. To connect to your PC you need a serial programming cable SC-09 however you are still using old technology which is not sold or supported anymore. I think that you are better of to contact the local Mitsubishi distributor and ask an offer for a introduction kit with a FX3GE or FX5 type PLC, (optional, depends on the intro kit) a GT touch screen, software IQ-Works and a USB programming cable. Most of the time they have a special offer to buy these components in an introduction kit for 1/3 of the real value. Updates are free if you register at the My.Mitsubishi portal. There is also a free download available for a 60 days trial. (check google to find it) https://us.mitsubishielectric.com/fa/en/about-us/distributors Good luck studying Best regards, Theo V.

Hi Myanmar, See the attached Word document for a small example of a retentive drivemotor of a conveyorbelt with start/stop. I hope this is clear enough. I had some trouble coping from GX developer so it looks a little poor sorry for that. (the result is what matters)   Best regards, Theo V. Example retentive marker in a FX1S PLC.doc

Hi Andy, Is this diagram attached what you are looking for? More info is in the communication manual in section 4.2.2 at: http://www.koningenhartman.nl/UserFiles/Product/Datasheet/GT1000%20Serie%20Connection%20Manual.pdf Best regards, Theo V.
