Hi Everyone! I try to read Analog Data in PLC Master through Salve Module (ECT-21) but i dont see any data, with an Digital Module i can read and write, but with analogic module i can't do anything. The analog module works perfect, i have 4-20ma Simulator and work fine. Modules: PLC: NJ501-1300 Slave: ECT-21 Analog: ADO81-V1 Can u help me? Regads..

Hi, I have a question about error clear on Mitsubishi Q Series (Q03UDE). Is there a way to clear 4100 error without power cycle CPU??? I've cleared the cause of the problem and I've tried to clear CPU error using SM50. I've put code 4100 into SD50 and then turned SM50 off and then on again, but CPU is still in ERROR state and I cannot switch it back on into RUN mode. I have to turn the power off then on again and that is solving the problem. The problem is that sometimes it is very hard to get to control cabinet to power cycle CPU. I would like to clear this error remotely if possible. Any ideas???

Hi Im working with an iQ-R CPU wich controls 6 conveyors with a CC-Link IE Field Network, the CC-Link module is a RJ71EN71. Each conveyor has a remote I/O (NZ2GF2B1-16TE Digital outputs main module with a NZ2EX2B1-16D extension for Digital Inputs). The communication in the CC - Link IE Field diagnostic appears to be OK, but I can´t send or receive IO signals from the Batch Monitor of Gx Works 3. Thanks for your attention!

Hello everybody. I am looking for a solution for an FX3U with mounted FX3U-ENET on the right, to communicate with an FX3GE. I need to read and write some device in the FX3GE from the FX3U. I have made a paired connection in the FX3U-ENET module and made an MC connection in the FX3G. But how can I send or read data? Is there another solution apart from the MC-Protocoll? I am using GXW2 version 1.551z. Languages: ST or FBD Thank you in advance Dave

Hello all, I have 7 Q series PLCs on a Melsec net/h network, Ladder Programming none of that fancy smancy ST stuff LOL. Were running the QJ71LP21-25. Now to keep it short I have used all most all my devices in my Network Range Assignment. I can not set up low speed range as I do not have enough Link relays and registers at all stations. No memory for more devices just trust that I can not do it... However I have an abundance of File Registers ( no I cant buy B or W in the PLC File params, well I can but it wont help because only one CPU is UDE the rest are H.) I have a project in which I must see about 50 words for each Station at every Station. I figured while I am setting up a Transient Transfer I will make a bunch of extra room for future updates and junk. My answer good or bad, is to set up some Send/Recv commands and do some Transient Transfer. I think I have it just about all figured out just a few questions. I have two manuals I have been getting my info from Q MELSECNET/H Network System Reference Manual ( I think SHNA080049)  and the Melsecnet/h training manual.  1.Any one have any better manuals that better cover transient transfer? Or that are new enough to mention GX Works2 instead of Developer? 2. Is there a max device for each send/recv? (I keep thinking it is 980 per station but no idea where I got this number)( I will increase the max # of transients in the supplementary settings under network range...) 3. Any precautions or advice like, Hey don't do this, I did this once and.... 4. It looks like as long as I use different logical channels for each station I should be able to send and receive multiple "messages" at once with no error?? (I will test this and look for the "no room in receive buffer area f222 error)  5. Will this slow down the Cyclic transfers (I will be watching the SW006D and so on to make sure it does not slow my regular transmission down.) 6. I will be using several special relays and registers in the program of course. Any I should use that are not obvious?  

We have L61's and L63's and are looking at upgrading them to the L7 equivalent. Has anyone had any experience of this and any pitfalls to avoid? Tech support have said that there might be issues with the comms cards resolved by updating their firmware. Is the upgrade that simple? We currently use Logix5000 at version 20.01 but are preparing to go to Studio5000 as part of the upgrade.

Has anyone discovered a laptop that will connect to all mitsi PLC types (and Melfa Robots) via MELSOFT TCP connection. My Dell 5510 seems to have the most random dislike for this kit. at the moment it is happy to link to Q series but wont touch FX at the moment (this has not always been the case). I have checked all basics I know; 1. Pinging 2. Port setting to Melsoft 3.  Direct connection to FX3U-ENET avoiding the unmanaged switch (altering settings to suit). 4. Using FX Configurator to try and diagnose,checking the module settings in the project. 5. Disabling laptop wifi connections 6. Disabling firewall and AV. 7. Trying to setup a UDP connection (this seemed to work on Q series) Pffff..... Any thoughts?....I am obliged to use a site networked laptop so there maybe IT issues....however due to my ongoing frustration I will order a laptop and use offline like a wild man

Hi all, I try to realize a cycle timer. A counter is triggered by a movement ( clamp close ) Then the machine does it things, piston here, and there and when the clamp closes again it should show me the real cycle time. Is there a timer/counter that is independent from the PLC cycle? I am using a CJ1M CPU11 Ver. 3.0

The title of this probably makes no sense, but I really wasn't sure what to call this thread. I'm working on a program for a Q Series, using ladder with labels.  This machine is going to have several status messages for the operator displayed on the HMI at the same time.  If I can figure this out my plan is to have a string display in the footer of a Proface HMI, with a "view next message" button.  Then I will write strings to the display giving the operator the status information and they will be able to press the next button to view the message- alternatively I could have a timer also that will auto refresh the display to the next message.     What I can't figure out, is how to queue the messages and have them wait for the button press or the timer to activate their MOV statement.  Essentially, I need to advance a register by one every time the "next" command is given- but if that status message is not active then I need to immediately skip to the next message.   I've thought about just incrementing a data register, but then how do I skip non-active messages? 

hi every one! i'm new with PLC mitsubishi, i have a Fx3u board and using Gx developer i can config input interrupt pointer in GX developer  but i don't know how to config timer interrupt with GX developer. i have read a lot of manual but i don't understand... someone can help me?????

HI Everyone,  Recently i have bought a plc fx3ge and gt2000 hmi .the problem is that whenever i use a device address d280.b1 in hmi .i am not able to use the same address in gx works for plc (LD D280.1).can anyone help me with this problem.   

We are communicating FX3GE PLC with Vijeo Citect SCADA. We tried various protocols such as MelsecNET, MelsecFX2N, Melsec1, etc. If you know how please help.

Hi. I'm hoping someone can give me an answer on this problem I'm having with a FX3GE PLC. I am trying to get a FX3GE plc to communicate to a drive over RS485 using a FX3G-485-BD card. In GXworks2. But am having no luck.  I have tried changing the PLC communication settings in PLC parameters between CH1 and CH2, But am unable to get any communication working on the front port. I have also tested with a FX3G-232-BD RS232 card and have the same problems. There is no activity on the SD RD led's and no data being sent. If I put the FX3G-485-BD card in a FX3G or FX3S PLC I have running the same code it works fine. So the problem I'm having is with the FX3GE PLC Please can someone tell me what the difference is with the front Communication port on the FX3G and the FX3GE. And how I can get the FX3G-485-BD card working on the FX3GE PLC. Thanks

Hello everyone! Could someone help me and tell me what the "D212" means? I know that to define the time of a TIMER you must put a k and number (miliseg).   Help.... :(

Hello to everybody, can someone help me find the DRIVER for a FX-USB-AW cable, it's for a Mitsubishi PLC FX3u Help please...  and thanks! :)

Hi I put value #80 in word 60 I run timer 2 with word 60 I replace word 60 withe the value #10 I run timer 2 again with word 60                       but you see the timer counting down from 80 instead of 10 So the timer runs first the previous value of word 60 before he runs with the new value although you see the new value of word 60 appearing in the timer. How can I let the timer run immedeatly with the new value.   Thank you

I tried setting parameter in gx works 2 for plc q series of q03ude cpu. I set retentive timer to 1k and reducing special link relay to 1k from 2k. then I set 0 in latch 1 start and 5 in latch 1 end. Getting error c4129 and c4139. I changed it to just 16 points of device, then put 0 in latch 1 start and 15 in latch 1 end, still getting same error code. In mitsi pdf of basic course, it just said all I have to do is to go to parameter>device>set retentive timer value to 32 from 0 to use 32 timers total, but I just simply getting error code of f1028 How to make it right? Got it now, have to uncheck retentive timer in tools menu.

Didnt know this before but should have anticipated it, I cant put 8 hours into say a TON or a TOF, etc. Only goes up to 2880 seconds, .8 of an hour. What would be the best way to go about this?

Hi there! I need to set up a communication link between an FX3GE PLC and a Melfa RV-2F-D robot with a CR750-D controller. Can I use the PLC's built in ethernet port for this? Is there a native driver for this (i.e. to read a register from the PLC into the robot controller)? Or should I use some kind of a no protocol communication? We also have a GT1455 in the setup and had in the past a solution where the robot was talking to an FX3U trough the HMI, but there was a lag in the communication which I would like to avoid. I am new to Mitsubishi so please bear with me. Thanks!

Good day lads, we encountered an error on a NByW-TW00B HMI, showing "Print Error 7300-FFFB". Checked already on the manual, which mentioned this : "Driver & UI Printer Settings Disable" (V106 manual, Section 7-9). What's worse is that NB manual doesn't give any workaround for any printer error. The NB is not connected to any printer. The "Enable Print" tickbox is unselected (checked both in the program and in the System Setup Screen). Also there is no button/macro which triggers any print function. Any of you have encountered this? Any advice is appreciated. Thank you

Hello, I have set up a new CC-link to add I/O to our existing factory PLC (Q03 series CPU). The CC-link system comprises of a master station (QJ61BT11N) and a remote device station (STlite STL-BT1) with several DI, DO and AD modules. Parameters are as per the STlite quick start guide example except no. of occupied stations is 3. In PLC Parameter I/O assignment the master station is a intelligent type and occupies 128 points from 0D00. Digital/analogue inputs are being read in the CPU and there are no error lights on either the master/remote stations. However digital output commands are not registered at the remote device station (LED lights on the module show which DO is active). Any help is greatly appreciated, I'm new to this and I've been hitting my head against a wall for a while on this one now. Cheers

Hi, everyone, I started learning very recently, and I have been writing this little program in which I communicate through RS-232 with a machine. Every time I send a command from the PLC I wait a couple milliseconds for the machine to send a response (a response must always exist, even if it's a mere acknowledgement response), then I save the response that the machine has sent. I organized my ladder logic by the commands that the PLC has to send to the machine (4 commands total, for example: execute this, give me status on that, etc). I started every ladder with an OSR and an AWA instruction, and when AWA is done I have a timer in the next rung to wait for the machine response, and after timer I have a ABL activated when TON is done. The Ladders are related in the sense that the end of each LAD contains a JSR instruction to the next command/ladder. So the commands/ladder always execute in a predefined sequence (LAD2 -> LAD3 -> LAD4 -> LAD5). The logic inside each ladder is like this (the last rung is a little different for the others, this is LAD2): ] start [ ----------------------------------------- [ OSR ] ] OSR OUTPUT BIT [ -------------------- [ AWA ] ] AWA/DN [ ---------------------------------- [ TON ] ] TON/DN [ ----------------------------------- [ ABL ] ] ABL/FD [ ------------------------------------ [ ARL ] ] test if ARL string is 0 [ ----------------[ JSR ] 1) Since I have to use timers so often in my program (they all last for the same period of time) I wonder if I could use the same timer every time (same Control File R6). But I'm quite lost on WHEN I would have to reset the timer, or if this would not be recommended at all, since the timer is still counting for more than one scan. Although I want to believe that the timer for that Ladder would never be counting after the JSR instruction, I think this is true only for the first time since the next time I turn "start" ON the ARL is not zero, so JSR would occur while the timer is still counting. I tried resetting my timer parallel to JSR and using the same timer in the next ladder, but then the timer only counted up for the first time "start" goes ON (I believe because the timer was constantly being reset at every scan). 2) Also using OSR with AWA was the only way I found of making AWA and TON to "behave" (that is, to make AWA only go ON once per start and the timer to go ON every time AWA is DONE). Would there be a better way to do this or is this acceptable? When I tried connecting "start" to AWA directly the program just didn't behave the way I expected at all, I believe because AWA would always be enabled for more than one scan, although I cannot explain why this would be a problem since AWA should only execute from the transition false to true, no? 3) I never clear my buffers or reset my ASCII instructions... when I try to clear in parallel with JSR some of the ASCII instructions' bit ER goes ON, and when resetting my ASCII instructions sometimes I don't see any before/after difference, but oftentimes I just see an undesirable behavior, and to be honest I'm not even sure where in the code I should do it, so I wonder if I should bother. More specifically, in which situations should I care about doing it when writing a program, and where in the program is it recommended to do it? So far I don't seem to have a problem, so I'm being willingly ignorant about it Any suggestion regarding my code/logic is much appreciated! Thank you!
