We have Q06UDEHCPU PLC. We require to attain 1k of file registers in standard Ram. Please find our settings attached - PLC Parameter.png; When we try to down the register file – we attain the following error; “Failed to access standard Ram” error message (attached - Downloading Error.png); The program is very small – and thus we have plenty of space as well.

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

I want some recommendations for a PLC that can hold its memory for long periods of time with no power. I have a customer that has the molds that only get used a couple of times a year and when they are not being used they sit in storage until they need them again. Currently they have a DirectLogic05 controller and what they have noticed is that when they pull these molds out of storage to use them, the program is lost and they got to download it again. They want to make it to were all they gotta do is plug and play basically for this machine. Is there a special module or a processor that can hold its program for long periods of time while it has no power on it?

CP1L connected with scanner symbol, with RS-232 on board CP1W-CIF01
FranciscoMYT posted a topic in CX-Programmer
CP1L connected with scanner symbol DS-4308 reading 2D data matrix, with RS-232 on board CP1W-CIF01 Hi all, need some help because I can't read the information. Let me explain, I have a PLC, " CP1L-L14DR-D " with a RS-232 option borad " CP1W-CIF01 " , a scanner Symbol DS-4308, and I'm trying to read a data matrix 2d barcode (I don't know if that matters). so I build a cable with the next configuration, (one side male and the other female) PORT CONFIG PIN OUT SCANNER CABLE RJ-50 TO RS-232 PINOUT Maybe I'm missing a connection? a bridge? power supply ? ground? in the program, I only have this to check the communication, When my reception flag complete (A392.06), my instruction RXD is going to execcute, reading in D1500 the data. if is any error in communication (A392.04) or overflow (A392.07), my port is going to restart (A526.00) (ignore w0.03) with the followign config: (9600, 7,2,E, RS-232C, End code: Received Bytes 3 and I'm reading only, data on D1500 and D1501, and the data makes no sense. with the configuration of End Code: CR, LF, can't make it work, I read nothing. and if I change the END CODE: Received bytes to 4, don't work. and my flag A392.04 go to ON. PLC HAS 4 PIN SWITCH, ALL ARE OFF The configuration on the scanner is setting to default and then config to RS-232 Standard. So, what I'm missing? bad connections? plc don't support? scanner config? program? -
Hello All, What are the methods to get the monitoring data from A series PLC? I know its not supported any more, interface modules are not available..., So the basically, If I want to write customer software (may be embedded) what is the protocol I need to follow? I am connected to CPU unit by the way, there is no other modules except few digital and analog interfaces on PLC. Thank you in advance for your direction, direction in any way would help!

I currently have certain amount of Recipe data located in form of Excel file on to a PC with static IP address. Is there a way to get that data inside the Nj501 without using an SQL server as I currently have NJ501-1300 which doesn't support SQL. I am okay to send data to the SD card I currently have on NJ PLC as it is easy to get data from SD card to the NJ501. If there is any example code or a link that helps me create i would be helpful. Thanks in advance. FYI: I am currently using NB10 HMI with NJ PLC.

Hello everyone, I am working with a NB10W HMI connected to a PLC NJ by Ethernet protocol, I would like to know where to start regarding the sending of data from the PLC to the HMI. I have a 50x15 array and should show all those values in the HMI for read / write. How to proceed? I started working with PLC for a while. I'm using Sysmac Studio to programm the PLC and NB designer to the HMI.

Hello everyone, I need the help to do setting of datalink between CJ2 and LOGIX-5324ER. The Allen bradley PLC was programmed by contractor and I have no software of it, so I am doing the network setting in CX-one network configurator. I tried to do the instruction in the Quick Start Guides on Downloads section here under Omron, but I couldn't find the option to register tags in network configurator. Is there anything wrong here? or is it possibly because of that they not support to do a datalink in these version of PLCs? They appeared like these in the pictures.

I have an FX3u16MR attached to two FX3u4AD units (right mounted). I am running the first two channels of the eight in 12 bit mode, the next two channels in 16 bit mode, the next two channels in 12 bit mode again and the last two channels are idling. All inputs are configured as 4-20mA. Working with the first channel only for now, what I am finding is that I have to load the gains twice for them to take. It points to a timing issue in the code that I am running in the plc. It just seems to have started happening though. Admittedly I am recoding so the ADC calibrates from a HMI rather than from a PC trigger which is what I had before. But I have just paralleled up the M register that invokes it. I am working through the code as I speak. If anyone has any idea's i would love to hear from you. I know this bit of kit fairly well I am just missing something here and it is bugging me. A problem shared and all that. Thanks in advance.

Hi everyone, I'm trying to use the cam control data by using an MR-J4-A-RJ and MR Configurator 2. When I switch the input "CAMC" to ON, I see that the output "CAMS" is switched to ON which means that the cam mode is activated. When I switch CI0 to ON to choose the Cam Data No.1 and switch ST1 to ON...nothing is happening like if there is no Cam Data. Please, have you any issue or idea ?? Thank you in advance Omar

CompactLogix PLC Family 5370 Data Byte Order
Muhammad Azeem posted a topic in Allen Bradley / Rockwell Automation
Hi, I am working on a project in Digi Module ConnectME9210 and sending data to Allen Bradley PLC (CompactLogix 5370 family). I am not sure which endian I should use to send data. Does Allen Bradley receive Data in Big Endian or Little Endian? I have another question as well. Can I make an EDS file to tell the PLC to receive data in UINT16, not as a single byte?

I know enough Ladder logic to get in trouble. Although, I do have a few PLCs controlling machines that I wired and programmed and they are running well (as long as I can remember what those buttons I added do.) I cannot figure out how to get memory into the PLC. For example, I have a Counter where I have entered the following: CNT 0005 W1 ( I am driving it with a 1s clock and the reset is an external button.)) I then went to working memory and entered a number as position 1 (I entered 234) When I load the program and press the button to reset, CNT is starting at 0. When I move the W memory from PLC to PC there is 0 at that position. All of the boxes are checked when I compile/transfer. Is my CNT format correct? How does one get the memory to the PLC?

Hello all i'm looking for some software to record a 100 plus channels maybe with an ascii string from a PLC? i want to be able to assign each channel with a unit and a range, flagging feature would be nice. - selecting the channels i want to view - auto start recording - save file and start new automatically -view and create reports preferably no additional hardware because of the amount of channels. this is to record an operators every move so in events of damage or plant failure we can quickly identify the problem (point the finger) many thanks dan

Hello all, i'm looking at installing a completely new network for our PLC system, using a ring topology. at the same time i would like to incorporate the IP cameras and VOIP into the same network. each system is on a different sub net, PLC = x.x.1.x, Cameras= x.x.2.x, VOIP= x.x.3.x estimated camera traffic will be 25 Mbps, PLC 10 Mbps, VOIP no more than 1 Mbps switches would be capable of 100 Mbps question: managed or un-managed switches? if it is possible to use un-managed without affecting operations then this would be a massive cost saving please only comment if you have practical experience implementing this many thanks Dan

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!!!

Fluctuating Parameters in CP1H PLC while connecting to 2 Computer
Rishi posted a topic in CX-Programmer
I have Omron CP1H PLC and using Ethernet Option board to communicate through Ethernet. When I connect PLC to 2 Computer it starts malfunctioning and values in register get fluctuate. while I connect single HMI it works fine. Kindly give solution if anyone know. -
Hello Everyone, Recently getting into Omron and I am wishing to pursue this type of PLC and software for a staple in my career. I have recently just graduated from a program involving PLC mainly Allen Bradley and one thing I have to say is that while making the transition from AB to Omron, the main difficulty I have had was with data types, specifically BCD, UINT, and CHANNEL. I am currently using the CX Programmer software for a few PID loops and they are causing me some great difficulty because normally I would just simply enter in all my values into a huge PID block in AB but that is not the case when it comes to CX-Programmer. Can anyone point me in the right direction of some manuals or e-learning places so I can quickly get a grasp on this so I can move ahead with the code. It is frustrating when you know how to do something and you just can't figure out how to put it into a software you aren't familiar with. Thanks for your help

Hi all, I have been getting to grips with the different graphic displays in CX One Designer but I am having trouble trying to produce a table which shows column one as a label and column 2 as data value that I am polling from a Modbus slave. From what I have read/tried the data block table seems to require a csv as the data source and I cant seem to achieve what I want with the standard table. If anyone can advise how I might be able to achieve this I would be extremely grateful. Below is the sort of thing I'm hoping to achieve but in a table format: Bearing 1 Temperature 80°C Bearing 1 Vibration 0.2 mm/s² Bearing 2 Temperature 82°C Bearing 2 Vibration 0.2 mm/s²

I have a reference HMI project that has many variables that have an Invalid data type. We are one by one trying to re-create the data types that are missing, but so far there is no easy way that I know of. Currently I re-create the UDT from scratch in a scrap offline project. (based on just looking at the variable elements in the ref project. Export the UDT to .XML file Import the UDT as a new custom structure into the toolbox At this point I can drag the structure from the toolbox into my variable list, and it creates a variable with what looks like a good structure. What I cant figure out is how to easily re-assign the old variable the new custom data type. Since the old variable is used all over the place, it cant be deleted, and if I rename it it changes every reference to it that exists, so that doesnt help either. The image posted shows the old variable "H_Header" and its properties as invalid type (also shows red X in the icon). below that is a new variable with the new data type. (no Red X). If I could delete H_Header I could then just rename the new variable to the same, but I cant because of its use. If I could change the data type from Invalid to H_Header, that would work, but its greyed out and wont let me change it. Any help appreciated

We have a PLC that controls a diverts for cartons. The PLC talks to a host to get the divert code and then this is used to trigger diverts through device net. The issue we are having started back a few months. We are getting good scans and the information is being sent to the host and back, but cartons are not diverting 100% of the time. If we remote connect to the PLC and have the program open, the issue goes away. When we disconnect, it issues occur again. The PLC has a wired connection through a network switch. Is this a problem with the PLC or with the network switch or somewhere higher up in the connection? If it is the switch, why does the issue disappear when we are connected? We are remote connecting with a laptop and the connection we use is wireless.
