Hi all, I have a global customer that still uses FTV SE version 10 (I'm sure some may know who). I provide a customised solution using CompactLogix 5380 series PLC and an FTV SE application for part of their operations. Something that has been on my mind for a while is the ability of local tags or variables held only at the display client (thin client in this case). I have used HMI tags and also tags in the PLC, but my need for local client tags is that I hold the current display name and importantly, the area of the display page. Essentially I use a common display page to show one of two areas, they are identical in appearance, just different areas, and make good use tag substitution by passing a parameter file to the selected display page. While the methods above appear to work, I wonder what happens when two users at two different display clients operate the application, selecting different pages from my menu. With either HMI tags or PLC tags, they would simply get over written by the last write by the last user, hence why I would like to use tags local to the display client. I would like to avoid any use of HMI tags stored on the server if possible. Any advice is much appreciated.

Hi everyone, I have a question for you all, Is possible to configure CJ2M-CPU11 with tags trough network configurator to connect Control Logix PLC using EthernetIP? I did a configuration with CJ2M-CPU31 and Control Logix PLC with no problem, but now I need to communicate CJ2M-CPU11 with Control Logix PLC using EthernetIP. Some of you did this configuration between this two PLC before? Regards!

I am copying some data from a vendor PLC through MSG instruction into my PLC through CIP data table read. Is there a better way to break down this array of data into individual real tags through an instruction (something similar to WORD_to_BIT instruction in Modicon). I was looking at FAL instruction but its not exactly doing what I am looking for. Any help is greatly appreciated. -
First of all, I'm running version 20.01.00 CCW. I have a project that uses a mciro870 and panelview 800. It also has 11 powerflex 525 VFD's attached, all ethernet. Everything has been going well but today I hit a wall when importing tags into the Panelview device group. I currently have a little over 800 tags and will have about 1400 I think when finished. The Plc section shows tons of memory available and when I check through 'config' on the Pv800 itself, it also has tons of memory left. When I do the import, it brings in 744 tags and then skips the remaining one. It even includes that in the msg block after the import. It has to see that tags or it wouldn't know that they are being skipped. I've been trying to work with Rockwell support ( of course I got the new guy who's never seen the software before) and my local distributor. I've looked through the rockwell knowledge base, the manuals and online and I haven't seen this problem posted. Does anyone know if there is a limitation on the number of tags? I can't image an odd number like 744. thanks, mark

Hi guys, I have been thinking about wether can increase the numbers of produced and consumed tags, between my plc-s. Currently I have two plc it already have produced and consumed tags, but unfortunatelly soon we are running out of free tags. I read the manual and it said I can make 125 dint tags, currently we have only an array with 10 element. If I make a new one and I kinda copy it, with different names, will it be work ? Or do I have to set something else ? Can I ruin the communication with the two plcs ? THanks ahead.

Hi All,Cx-Supervisor, NJ501-1340, Sysmac Gateway.I have been writing an update for a project and converting to this new controller.It's a pretty big project.Using a combination of Ladder and ST.Using Cx-Supervisor 3.5.I created some new Variables in Studio and made them Publish only.Started to create Points in Supervisor and made them I/O connected to the variables in Studio. No problems everything was connecting and working just fine.Then one of the points would not update. I could change it in the PLC and it would not change On the HMI.I deleted it and recreated it and it did the same thing. (sometimes points in Supervisor just stop working and recreating them fixes it).I then copied the control and pasted the old point into it and it did the same. Then other started to fail. Showing no reaction.I stopped the gateway and restarted, no help, I rebuilt the HMI, nope.The can check the tags in Sysmac gateway and they always change when the PLC changes but not the HMI.I checked the point maintenance in Supervisor and it would not change.I dumped all the affected variable in the PLC and in the HMI and recreated them. Then it got stranger.I could change some on the HMI and it would show in the PLC but not the other way.This is on Bools and UINTS.Stopped CX-server, tried using it with Win8 compatibility. nope.Pulling my hair out now. I should be coding but I'm trying to get the apps to work.Any ideas will be used with thanks.Peter

Hi All, Hope you all doing well in this pandemic life. I would need your expertise with an issue I have been struggling with for past few days and thought to reach out here. I am working on a migration project with GE PLC and Citect SCADA 7.10. The GE PLC is migrated to ControlLogix L74 Rev24.10 while Citect SCADA is retained. For testing I only have L71 and L82 and could not managed to organise L74. When the code the loaded in L71 and connected to Citect, I cannot see tags in Graphic page but I see the subscription.txt in Debug folder shows all tags good . The same code when loaded in L82, the Citect works instantly. Does anyone know this behaviour of PLC and SCADA? Regards, DeeEngr -
I have multiple PVP 1500's on the same network. From the one in my control room i need to be able to see what user is logged into what HMI. How would I address the system tag of another HMI on the same network would I use the IP address? thank you for any help in advance -
Hi Guys! I have an another question , I hope you guys can/want to help me. I have some problem with an proface panel. I want to make a hisotrical trend, but when I want to select the channels (tags what I want to monitor) I can't select anything, because undetermined. I think I should set the tags kind of a buffer list, but I don't find it. So my question is how can I set the tags. I can't changed it at all. If the answer is I need to make a buffer list, then where can I find it ? Thank you so much.

Hey guys, I have worked on the FTView ME platform many of times. I am now working on a FTView SE (Local Station) application, and I am having trouble connecting an Offline .ACD file to my program so that I can design. If someone could help me with this it would be greatly appreciated. Thanks in advance! -
Hello, I have a micrologix 1400 plc connected to a length measurement gauge. The gauge sends an analog value to the plc to an analog input. I convert the value into a dimension and send it to F8:0. but I need this value in three different steps in the program. Since i just have one element of float (F8:0) is there anyway i can store the value in a different location or create more floating point tags eg. F8:1. F8:2 ? Thank You

Hello I downloaded a .mer file on the Panel view 1000 but it shows errors on the display graphics. i have configured the Rslinx communication several times by selecting the rigt PLC in Design and Runtime mode. I am using Facotry Talk view 8.20 and creating 5.10 runtime file. Please advice. I was able to correctly download and use the HMI on a similar machine. I dont know what am I missing on this one. Thanks Pratik Jain

Good Day, I have done a quick search and couldn't find any pertinent information, so I was hoping somebody else might have been through this in the past. We are using a 1769 L32E and are trying to record the ambient temperature of the cabinet the PLC is in. We don't want to incur the expense or use the space that an external temperature sensor/thermocouple would entail. Is there an onboard temperature sensor that has a tag available in the ladder? Thanks, Jed

Hi all, I am sure this has been done many times but I am relatively new to Siemens so please bear with me. I am using Simatic manager Step 7 for the plc programming and TIA portal 13 sp1 for the HMI (TP1200 Comfort panel), this communicates via Profinet network, we have 96 physical inputs and 64 physical outputs on the PLC. What I would like to do is add maintenance pages to the HMI to give a graphical representation of the plc inputs and outputs, most of the inputs are assigned to various DB’s but not all and the outputs are the same. So page 1 would be input card 1 would be I0.0, I0.1, I0.2, I0.3, I0.4, I0.5, I0.6, I0.7 and then I1.0, I1.1 etc, etc, for every input and output on the PLC. My question is, do I add all the physical Tags individually into the HMI as (Tag 1 - Input I0.0 = I0.0) or would I be best using the DB addressing where possible (DB1020.DBX0.0). is there a preference or best practice to use Physical or DB addressing, would one be more reliable, use less resources, quicker over the network? As i will have over 200 tags will this slow things down or cause problems? So for the representation of the I/O i am using a rectangle, in Display / Appearance and setting this to change colour as the tag changes state, all basic stuff I have done one screen and it works on both DB and physical, but as I am new to Siemens i am not sure what is the preferred technique to use before i do the rest of the screens

I have entered the messages many times into the Alarm Setup but every time i re-open the alarm setup, every message that has the Trigger Value=1 will be deleted. Anyone have a similar issue?

I have L61 with nonvolatile memory installed. The controller will read the program from CF card on power up. The issue is that some variables are lost or not the most up to date values are read from the card since it remembers them as they were last stored on the CF card. So stuff like motor run hours, etc is not up to date. Is there any way I can update these variables or tags on the CF card as they are updated by the process? Or what would be proper way to deal with this issue? -
Quick question, but can Factorytalk View Studio read the tag descriptions in Logix designer. I would like to make the alarms just read the PLC tag descriptions and since the comments are now stored on the PLC, I am wondering if we have access to them from the HMI... Thanks in advance. -

I have a FactoryTalk 8 application that exhibits some weird symptoms when I run it. I have buttons whose "visible" state and "enabled" state are based on HMI tags. The states of these buttons don't update. I have screens that fail to close when the "abort" command is issued. I have vba that connects to a tag group, which fails to retrieve the value and produces an error. Some tag values from the PLC (always direct-addressed, I think) show up correctly, even when other symptoms above are happening. These issues randomly go away sometimes after a restart and the entire application runs fine. Does anybody have a clue what could be doing this? (Using Windows 7 Professional 6.1.7601 Service Pack 1 Build 7601, SE version 8.10.00 (CPR 9 SR 7.4), Internet Explorer 11.0.9600.17633) -
I have been supplied with a list of tags from a vendor containing flags indicating if alarm conditions are on. These tags have the format AlarmGroup.Num.1 through AlarmGroup.Num.10 as recorded. Reading these tags as presented by making a read request to the Read Tag Service fails with general error code status 0x05, "Request path destination unknown. Probably instance number is not present.". I am using ASCII extended symbolic segments to translate the tag into a path so the instance number is not required for this approach. Upon further discussion with the vendor I found out AlarmGroup.Num.1 refers to bit 1 of the AlarmGroup.Num tag that is a DINT tag. I can successfully read the AlarmGroup.Num as a DINT but I was hoping for a more universal solution that would not require me to add solution specific parsing functionality to identify tags that refer to individual bytes from other tags and manually shift the bits as required. I am very new at this and I want to know if it is possible to address an individual bit (for reading only) from a DINT tag and how to build the path to access it. Are there other types of segments other than the ASCII extended segments required?
