Data entered into the PLC D memory table does not end up in the instructions and I'm not sure what I'm doing wrong. For instance I want to use the CP1W-DAM01 to change a duration value. I have a symbol setup using the corresponding address setup so that it ties in with my timer but the data does not transfer even thought the value shows up in the table. I'm also using it for parameters on a scale instruction, same issue. Any ideas.

I was wondering if anybody out there has ever made a generic popup to deal with multiple devices, similar to what you can do with factory talk and wonderware. I want to be able to index addresses from the PLC to the PT memory but it doesn't look like you are able to do this. Is there anybody out there that has come across this same problem?

Generating UDT Templates from Excel
ottomation posted a topic in Allen Bradley / Rockwell Automation
Does anyone have any tips or tricks for generating UDT Templates from an excel spreadsheet? It says in the help files you can copy/paste from excel into the UDT Template, but it seems to only allow that cell by cell, instead of the whole table of data. This is painfully tedious when building larger interfaces. I've tried saving the spreadsheet in various formats (CSV, PRN, tab delimted txt) and I've tried various versions of RSLogix from 23 to 31. I can't seem to find any detailed info on how to do this. I've seen some other forum posts regarding using scripting to generate the XML to import the UDT, but I don't understand why I can't simply copy and paste the info in. Is this really that difficult? Any help would be greatly appreciated. Thanks Otto -
Good day. I'm using 1756 L71S GuardLogix Integrated Safety Controller with Studio 5000 v28. My controller is connected to a third party software through ethernet connection, it simulates my project hardware and provides all the signals to my PLC. To know all the hardware signallocation at PLC memory, it uses a Tag export file provided by Studio 5000. In other PLCs, when you declare a variable as hardware input, you have to select in which address from the memory you want this input to be read, something like "Bit Input 0.0". But in AB this step is skipped, that is all addresses are managed by Studio5000 and hidden from the user. Is there any configuration at Studio 5000 that let me assign or at least see this addresses? Normally I would prefer my tags addresses to be hidden, but in this specific case it is more useful to know memory addresses.

Hallo. Can someone shed some light on how much memory st takes ? does it use more that traditional ladder? i find that a routine with a couple of thousands of lines uses over 500kB is there any tricks to lower the usage? Or is it just what it is, and buy bigger cpu’s

Hello people, I hope someone can help me with this. The system is connected with 8 PLC's. I want to transfer the data memory of a PLC to another like this: D850 from PLC2 to D900 PLC1 D850 from PLC3 to D901 PLC1 D850 from PLC4 to D902 PLC1 D850 from PLC5 to D903 PLC1 D850 from PLC6 to D904 PLC1 D850 from PLC7 to D905 PLC1 D850 from PLC8 to D906 PLC1 The data memory is an integer. -
Hello! I am using S7-1200 PLC 1212C AC/DC with configured Modbus TCP Server. I can already read/write Inputs/Outputs (Coils) and Memory Words. However I'd like to read/write Memory BITS. Is it possible? If so, how? What addresses should I use in TIA portal? And which function codes on client side? Thanks in advance!

Does anyone have any experience with the recently released user web interface for the iQ-F and iQ-R series. Supported by GX Works3 version 1.047Z or later, the firmware Version 1.100 or later. We have the sample user web interface running in a FX5U, its working very smoothly. I am currently looking into how to edit the html page, does anyone have any tips or useful tools/resources that I could use to work things out. iQ-F Customer News regarding FW Update 08-2018.pdf

Hi All, Just to verify if the "memory card" , in attached document Page 4 highlighted area , provides Omron CJ2M CPU21 to retain memory when powered off? If yes, for how long can the memory lasts without being charged? Isit capacitor or battery? Thanks in advance. Regards, Summer cj2m-cpu31.pdf

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?

Hi Everyone We are setting up a initial training in PLC programming for technicians, I got some experience with SIEMENS S7 but this seems to be an expensive choice, we would like to opt for a budget PLC but at the same time would like a user friendly software for teaching......I would like to have views of users of other PLC brands such as OMRON, MITSUBISHI or even Schneider??? thanks Jay

Dear All, In one of my projects I need to login in HMI via Windows Linked Users i.e. Domain Users..I have never done this before & don't I have any sort of idea regarding this..This is possible in Rockwell HMI's but not sure about Beijer IX HMI's.. So if anyone has done this pls do let me know.. Thanks, Krishnakumar Mishra -
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.

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?

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!!!

The information required includes; [1] Purpose of macrocode (incl advantages) [2] its utilization's effects on the PLC programming memory (it appears that it consumes more programming memory. [3] any reference documentation that could be used - containing specifically information regarding this feature (note most manuals doesn't discuss this)

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.
