We have a QSeries PLC. Q25HCPU. We also have a PLC program. We found that the address registers (also known as device addresses) attain a z-value added next to it - automatically over time. We are not sure why this is the case. Nonetheless, when these values get added (by the PLC - not the engineering software), some of the functions in the PLC doesn't work. We found that by formatting the CPU, and reloading the program, allows for the system to work again (temporarily) for a few weeks, up until this problem occurs again. This problem occurs across various CPUs (eliminating the potential for hardware problems. These z values can be seen when a program comparison is done. (see attached file). The questions become; 1. What is the function of these values? (why does the PLC add them? 2. How can they be permanently removed?

Hello I have been using GX Works 3 for a while now and I have discovered a couple of things, maybe bugs. I have not had any training for the software or hardware so maybe I did something wrong. 1 Labels. If you sort a global label table into any order other than the unsorted order that appears by default you are unable to create, delete or edit any labels. Our Mitsubishi representative discovered that if you click on the column header between 'Data Type' and 'Class' the order does not change but now editing is available. This, it turns out is a really bad idea. It seems the position the label was in when it was created is preserved, I think this is the unsorted order you get by default. If you sort the list and then delete a label it is possible that the label that should be in that position is also deleted. I have attached a small project to demonstrate this. Open the Global Labels notice the order they were created. Now change the sort order, click on the column header I described earlier to make them editable and then delete the label in position 1. For a while I thought this was the only problem but recently there has been a number of instances where I have created a label, given it a carefully selected address only to discover that it is being overwritten by another variable. I have not been able to work out exactly what is going on but I believe it is connected to the sort order of the labels. Also if you sort the order and change an address, have you changed the address of another label? The only solution I have found is to keep label tables very short so they are managable without having to sort the order, that is probably good practice anyway 1 Axis software limits. I have been using a number of axes in pairs, in incremental mode as caterpillar feeders, using FX5U-40SSC simple motion modules. I had a problem that the axis synchronised to follow would suddenly stop moving, the customer was having to power down the machine and start again. This problem persisted for months with Mitsubishi scratching their heads unable to fathom it out and ultimately stating that the problem must be in my code somewhere. It was suggested by the customer that it may be getting to a software limit, I showed the customer that the software limit was disabled in the setup and it was confirmed by Mitsubishi that it was not the problem. guess what, it is a problem. Once the actual position reached the limit of the double word memory it would stop moving. The solution is the take the servos out of synchronisation in order to set the position (datum) to zero every cycle. Unfortunately the drives do not always re-synch on the first attempt so you have to keep trying till it does, this now causes slight variations in cycle times but it works. Andy EDIT: I have since been informed that to disable the software limits they must be set to zero. This implies that the Enable/Disable setting is invalid and the limits are defaulted to their respective max values. Surely a default to zero would be more appropriate.     Label Test.gx3

Hi After updating CXS to ver. 3.4.1 I can't see point address I can see them when I editing but in the list form only the array len. is shown. When I enter a new point I can see the address. Anybody now hove to solve that ? Banker

Hello i'm new in all things about plc, i do a project for school and i use a festo fc 34 plc. The plc is programmed via serial port RS232 my pc not support a serial interface and i use a RS232 to usb adapter. when a try to download the program to plc give me a error: "ERROR: Cannot access controller".  What i do wrong.  Thank you in advance and sorry for my English. Have a nice day.

Hello, I would like to see your logical opinion about this situation and in which part of system where I need to find solution - software or in the physical field. Subject: Twelve old system based on Mitsubishi PLC AnS series, Profibus Here is pneumatic transport, with 5 lines, each line have a shredder and discharge valve. A few months ago, when line 1 works , display shows line 2 and vice versa, it was first problem, but the system was still working. From the last week system doesn't work. On the display appear line 3 in works, but system can not started. Alarm shows Double address (perhaps two valves have some address), Alarm still appear after reset and even all lines are turned off. What is your opinion where to find proble (PLC, I/O moduls, cables,...)  

Hallo. Im hoping someone can shed some light on these topics. The company im working for have been using gx developer iec 7.04 for ages. The setup we have been using is QxUDE plc with beijer HMI and FR-E700 inverters on profibus. Recently(finally) we have been forced to start using gx works 2 because of newer plcs. With new software come new questions as always. And since im feeling we have been hanging in old software for too long. I want to make sure we are up to date this time. The setup we plan on using is QxUDV cpu, CC-link ie (QJ71GF11-T2), FR-A800 inverters and GOT 2000 for HMI I have made a few project in siemens and TIA portal. And software wise it has always annoyed me, that mitsubishi lacked the same integrated software package as siemens. This made me discover navigator. With system labels navigator makes the variable control, hardware setup and project overview im missing from siemens possible. My question to navigator is. Does people use this? i dont see much about it on the forum? is it already outdated? Gx works 2 or 3 Again i cant figure out what is new and what is old. What are the pros and con for choosing either? CC-link ie or CC-link From internet reading. I find that IE is the newest and faster CC-link version? Is the classic CC-link on the way out? If not why should i choose IE over classic? When setting up CC-link IE in navigator i dont get the same hardware in the catalog as CC-link. To setup inverters i need to user general intelligent device station. Whereas in cc-link i can choose FR-inverters. Is this the way it works? or can hardware catalogs be updated somehow? Blocks for FR-A800 Maybe its just me. but i really think the search function on the mitsubishi download page is crap. When i filter QPLC i get LPLC etc. ive been trying to find some blocks to control inverters without luck. Do i start creating it myself or can you point me in the right direction? I know these are a lot of mixes questions. But i feel we have been non-efficient for years because of bad software choices. Hope someone can shed some light one these points.

A motor will be controlled by two switches.The Go switch will start the motor and the Stop switch will stop it. If the Stop switch was used to stop the motor, the Go switch must be thrown twice to start the motor. When the motor is active a light should be turned on. The Stop switch will be wired as normally closed.

Hello.   I'm trying to communicate between two PLC's  using FINS function block _CPU011:ReceiveData.   PLC1: IP 192.168.1.50 (MASTER)   PLC2:IP 192.168.1.51 (SLAVE)   If I don't use »IP Address Table« everything works using NODE number &51.       The problem is that on the real project these two PLC's will be on different subnet.   For example:   PLC1: IP 192.168.1.50   PLC2: IP 192.168.2.50   So I will have to use »IP Address Table« to achieve communication between these two PLC's.   I tried to sett IP Address Table on MASTER: Node 1=192.168.2.50   But If I try to communicate I see that packet is sended to network but I've got error #1005.   Do I have to sett the SLAVE IP Address Table?   Hoe to do this?   What are the right settings for MASTER and SLAVE IP Address Table?     I'm attaching pictures of CARD settings.  I don't want to use CX-Integrator because I would like to make project to UPLOAD and forget.       Thanks.  

Looking for Socket TCP/IP communications program examples for Mitsubishi PLC iQ-R R04CPU using GX Works3, to compliment the Mitsubishi Ethernet manual Socket commands instructions. Unfortunately, the manual is missing real application ladder logic illustration examples of these commands. For example, the Socket Open Connection command, does not describe in what order or format to enter the IP Address.   For example, to enter IP Address 192.168.1.100, does the most significant octet 192 is entered or stored first in the lowest memory storage register (Big Endian format) or does the least significant octet 100 is entered or stored first in the lowest memory storage register (Little Endian format)? I am trying to write a simple Socket TCP/IP communications command that will write about four registers from an existing Mitsubishi PLC R04CPU (Socket Client) to an Allen Bradley PLC ControlLogix (Socket Server). .

Dear all, I'm first time using M580 (hotstandby). Now finish the configuration, but the problem is how to write the address for Digital Input, Digital Output, Analog Input, and RTD module in elementary variable ? I try to put name DDI_1 and the address is same with M340 topology like %I2.1.0.1.1  and for digital input but got message after build : {Elementary Variables}    :     The instance is located on an address that isn't configured. :     DDI_1 Thank you for your advice regards  

I'm using Controllogix L61 redundancy system as a slave with DCS using ethernet tcp/ip socket programming. The communication between master and slave will fail after a switchover. Kindly give solution for this. Thanks and regards, Rasu

Hello, I am working with e5cc-t programs, for heating application. I need to find a way, to start program, when temperature reaches set-point of first (no. 0) segment. I think that, there should be some kind of setting, but i cant found it.. I've done this with PLC, but this is not an solution for this application. in conclusion: After program starts, it has to reach set point temp, and then hold temperature for certain time.

Dear all Please identify me i am having one Issue in my PLC.When I changed the IP of my plc then suddenly its showing error ERH its mean IP address wrong but  My CPU setting is same like previous means unit no=0, x16^0=0 ,Node=x16^0=1  and IP is 192.168.0.15 Mask add.255.255.255.0. but when I, transfer to PLC (in Program Mode) its not transferred(Failed to Transfer) please rectify me where I am doing wrong.

it possible to get the program backup form plc fx2n 48mr and roster it in 3u-48mr

I READ IN THE MANUAL FOR THE CJ2M-CPU34 THAT IT IS POSSIBLE TO CHANGE THE IP ADDRESS BY WRITING TO D30098 AND D30099 (MY DEVICE IS UNIT 0).  I TRIED TO DO THIS ON A TEST PLC BUT AM NOT HAVING ANY LUCK... I WROTE MY IP ADDRESS #C0A8 TO D30098 AND #0E30 TO D30099 (IP ADDRESS 192.168.14.48) WITH THE CPU IN PROGRAM MODE, I SET THE RESET BIT (A501.00) TO TURN ON ON THE TRAILING EDGE OF THE FIRST SCAN BIT, I CAN TELL THE CARD RESETS BECAUSE I AM CONNECTED VIA ETHERNET AND I GET DISCONNECTED, BUT THE IP ADDRESS DOES NOT CHANGE.  IS THERE ANY WAY TO CHANGE THE IP ADDRESS WITHOUT CX-PROGRAMMER?  I NEED TO GET A SOLUTION TO MY CUSTOMER TONIGHT AND MY SUPERVISORS DO NOT WANT TO RELEASE OUR DEVELOPMENT CODE TO THE END USER.   THANK YOU!!!

Looking for some servo application help. Software: I have GX works 2, GT Designer, and GX Developer.  Hardware: PLC L06CPU-P, GOT2000 HMI, MR-J4-350B servo amps, HG-JR35JK motors, LD77MS2 Pulser I have (2) AC servos that will simply move an aluminum frame backwards and forwards using a FESTO belt mover and I have a servo gear reducer 20:1. I have a "simple motion module"and all of this hardware and software, plenty of time, and would really like to finish this project off. But this is my first servo and my first hmi project. I have some experience with Omron, Mitsubishi, and Allen-Bradley plc's, and consider myself novice at best. Any sample programs or help getting me started would be greatly appreciated!  

I got a CJ1M CPU11 that I can connect to but I can just go to run mode but when I try to switch to program mode I'm tell that I can modify the mode

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!

Hi everybody. I'm just getting started with GX Works 3 and I feel a bit lost. If I have an external help file for my function blocks, how do I register this in the program? I can't find it anywhere when I double-click the fb library or in the e-manual Viewer. The file format is .CHM and I have imported this to GXW2 earlier.   /Niklas

hi.  i want to make some program that work with indirect adress. example, i make program with many much type. I make with Got-1000 mitsubishi.   can you bring me some example? i am sorry, my english is Bad

I am unable to read FBD program in RSlogix 5000.It says editor not downloaded.I m able to see ladder logic programs.

Hello I am at a loss here. There is something happening with TON_2 that also affects the variable STEG. Even though the input to TON_2 is false, IN and Q are true. Suddenly IN and Q turn false, and at the same time variable STEG makes a jump from 3 to 4, even though criteria for this step is not confirmed. Have had to override this fault by introducing a SR-latch and outside of block make a comparison between NIVÅ_FÖRRÅDS_KÄRL and 150.0 By the way, TON_2 is not declared globally. Would be very happy for suggestions and pointers. Cheers // DAN PE2 Jump.avi PE1 Jump.avi
