  1. Hi everyone, I just want to layout the structure of the question. I have a GOT2000 (GT27* series) that I have hooked up and communicating with an Allen-Bradley PLC. I have established connection and can pull out certain tags values from the PLC program in RSLogix 5000. While I can read the tag values, I cannot modify them (in certain conditions).  So let say that I have a User-Defined Structure named "Smoke_Detector" and here are it's available members: Smoke_Detector:   - ALARM (BOOL)   - ON_TIME (DINT) * DINT in Allen-Bradley but Signed Binary 32   - Battery_Life (REAL)  My question is that while I can read and display the tag and its members through the following:   - LAMP for Smoke_Detector.ALARM   - Numerical Display for both Smoke_Detector.ON_TIME and Smoke_Detector.Battery_Life But when I tried to modify the values via a Bit Switch or Numerical Input, it does not operate on them.  However, if these tags are members are just standalone tags, meaning that they are not within a UDT in RSLogix 5000, then I can operate/ modify them just fine.  Here are the things that I have tried: * Making sure that the permission are set to Read/ Write in RSLogix 5000 * Making sure that the tag definition in GT Designer 3 follows the structure where @[channel]:[Network #]:[Station #]::[Tag instance and member (e.g Smoke_detector is the instance and Alarm is member] Any possible insight and input are appreciate! 
  2. Proface historical trend

    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. 
  3. Any new tags I add in studio 5000 the HMI project shortcut cannot locate the tags, it says unresolved route to processor. It's the same shortcut all of the other tags are using. Please help. 
  4. This is my first time to the forum and I am still very new to plc programming. I just had to move all of our software over to a new computer ( kind of new) it's running windows 7 pro. The same is as the computer before. Same computer name, same I'm, same file directory. However when I add tags in studio 5000 and reference them in the HMI, it says it is unresolved in route to the processor. It only does this for the new tags. I used the same shortcut and everything so I am at a complete loss here. What do I do.
  5. 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!
  6. Micrologix 1400 Float TAG

    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

  8. could you tell me how to create internal tags in DIAview and how to dynamically change the colour of any object taken in SCADA  
  9. 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
  10. GXWorks2 Label changes

    Hi Sorry if this has been asked before but I have done some searching and couldn't find any answers in the forum. If I have a label that I use in my ladder, I can edit the address of the label any everything works OK (i.e. the ladder references the Label and not the direct address) If I need to change the text of the label, but keep the address the same, the ladder fails as it is using the label as the reference to the address. Is there anyway I can change a label and have it automatically update the ladder with the change  e.g. lets say I have a label called 'counter_1' which is used throughout the ladder code. If I want to change the name of the label to 'counter_A', I can alter it in the Global Labels (the excel type thing), but then have to update it manually everywhere in my ladder. any help would be much appreciated thanks Andy    
  11. 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
  12. HMI I/O Tag addressing

    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 
  13. 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?
  14. Hai dear all , i am facing a problem with  Rsview32 . In my rsview32 project "derived tags,data log,alaram log are not working but it shows status of another tags comming from PLC.Before this tags are working properly.i tried I restarted review 32 project and computer,command line enter "derived on (file). Still it is not working.anybody can help me for solving this problem.
  15. 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?
  16. Hi, I have a a few substations and I´d like to have a local SCADA in each of them. What is the best scada to use with reasonable price? Does anyone know if there is a solution without the need to have a PC for each substation? Thanx
  17. 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.

  19. Hello, I am new to the connected components workbench software. I am working with an AB panelview component Hmi and would like to create numeric buttons to load integers into user variables in a schnieder LMD servo motor. The motor uses Modbus TCP to communicate. It appears that if I click on the numeric buttons properties there is a "Write Tag" of which you can use some default tags or create a new one. I am assuming that I need to create a new one with the motor's addressing but I'm not quite sure how to accomplish this. Any help would be much appreciated!!! Thanks, Steve   
  20. Hi All: I am new to Citect and looking for a way to create 1 page that has 25 valves (genie that pops up a super genie) and some analog genie/super genies. What I want to do is create 1 page and dynamically replace everything when someone selects a different rack in the system. I have 4 systems that have the exact same equipment times 10 so I want to avoid creating 40 different pages. Can anyone help with some ideas on how I can accomplish this? Thanks M
  21. 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)
  22. Hi friends, The scene is like this... I have some 200 energy meters whose readings are continuously logged at 15-min intervals into a logging table. The meter does not have any other value logged. Let's consider these readings as analog tags. However these tag values are continuously increasing to ever larger numbers. Thus we have a problem for display on trends. Customer now requires that the Citect shows usage trends for any meter for a specified period of the past. That is to say, the meter that he wishes to observe is selected - along with a period typically between 2 dates (perhaps also with a sampling period) - and the trend must appear. So in other words, given a single trend object, how do you make values appear for any selected tag on this trend. Perhaps this can be overcome by some genie/super-genie mechanism. My approach to this is...For the selected meter, I use SQL to query the 15 minute logged values (also taking into account the required sampling period) taking the reading on starting date as initial. All values thereafter are subtracted -within the SQL query- and the result of this query is kept in a 2 dimensional array(x for time, Y for value) or a new database table so that the trend displays values starting with zero. This much I can do with Cicode. After this, I need a method to display the values so obtained in a trend object. Essentially this is the same as feeding a trend object with a set of X & Y values that I have in the form of an array or in a database table. I shall greatly appreciate any help to meet the above objective. Thanks for looking in. With best wishes.
  23. Reporting for Siemens PLC

    Hello, We want to do excel reports on Siemens PLC. We do not want to use historian programs. Do you know another programs?
  24. Copy HMI Tag value to parameter

    Is there any way to copy the value of an HMI tag to a parameter (FactoryTalk View ME 8). I am looking at doing something like: #100 = HMITag1 value I get #100 = HMITag1 name when I try anything meaningful. For example, if I have HMITag1 = test. I want to get #100 to equal "test", but I keep getting #100 is equal to "HMITag1". A little more background in case there is a better way of doing this. I have several components (pieces of equipment) that are the same. Each has its own program on the PLC that includes a group of tags for the component's settings. Most components use the same settings by copying tags from the controller level to the tags at the program level. A couple components need special settings. I have one HMI screen that each component will display for settings. A parameter file for each component will be used to display the settings from the proper Program. The parameter files have a tag for the program name (#100 = Program:ComponentX). On the HMI components I have {::[PLC]#100TestVar1}. This works great when #100 is a program name (the special cases). I was trying to get #100 to equal a blank so the object would access the controller level tag so any changes to the global versions would be across the board. I thought I could create an HMI string tag equal with no value to accomplish this. I just can't get #100 to equal a null string.
  25. 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?
