Hi, We have an application that triggers batches in FTBatch system. This is a dot Net based application created for our client. Now the client wants to see some data from the PLC on this applications UI. I have a ControlLogix with RSLinx Classic Gateway. I was thinking of picking up the data from the PLC via the RSLinx Classic Gateway OPC and display. Is there any free OPC client code or component available? My dot Net programmers are not familiar with OPC. I need something that is easy to configure and use. Even something like a component that can be called to fetch the data can do. Kindly advise as to how I can acheive this. Regards

Hi, I have an application that uses NI PACs. The customer has requested that the application have a mobile control through a tablet PC having Windows XP and running LabVIEW executables on it (no code development on this PC). The LabVIEW on the tablet PC will act as a sort of hand held HMI. The application on it is going to be simple start/stop and parameter display operations. Can we have such an arrangement? I am planning on using the LabVIEW 8.6 version. What problems should I expect? Thanks in advance... Regards...

Hi, I have a program, probably written in Modsoft. I have been trying to open it using Concept 2.6. The project does get open in Concept, but there is no PLC configuration, no symbols, no segments! These are the files that the backup contains... .CFG .CUT .ENV .IMG .MAP .PCI .PCM .PCT .REF .RFD .RFI .RFS What is missing? I 'm guessing .PRG and a proper .CFG. Thanks in advance.....

A few days back and after a lot of sifting through the internet, I did find a getting started guide for InTouch 10.0!

Hi, I have just started using the Wonderware InTouch 10.0. This is the first time I am using InTouch. I created a screen in the WindowMaker. Here we use objects created in the ArchestrA IDE(the global objects, I dont know excatly what they are called!). Created a new instance for each class. The tags were then assigned to our application in the Galaxy. After this I tried to deploy the tags. But, whenever I try to deply the tags, I keep getting a message (something like this):"Unable to deploy the tag x as it has similar object id as tag y". Could anyone please shed some light on this? I tried to look in to the objects and tags properties, but there was no specific object id. The SQL Server has some tables for our Galaxy like gobject_id. What is their relevance? The tag y are tags that I had earlier deleted from ArchestrA IDE. Any help would be appreciated. Thanks in advance. Regards, Mandar.

Hi, I would like to know if any primers for Wonderware Intouch are available.Something that outlines the different features available in the product and how to access and use them. Any help would be appreciated. Thanks in advance Mandar

Hi, I woulld like to know where I can get detials on the Logix architecture. What I want to know are things like;what kind of processors are present? Are there different processors for backplane communication and logic processing? So on and so forth. What litreature I have, does not give any details on these. I have also tried the knowledge-base, but it was not of much help. Thanks in advance.

Hi I am working with Intouch 9.5 1) I am using a list box aand combobox option. I want to imoprt a chunk of data frm Excel in to list box or combo box. hw can i do it. 2) I am using a numeric entry with popup as key pad. hw can i change the Min & Max value for the key pad by referencing to some external source. Thanks, Mandar

Hi, If you want to reference Recipe_Storage[X].Product_Name, and use indirect addressing, then your COP instruction should be as follows: COP New_Product_Name Recipe_Storage[Product_No].Product_Name 1 The Recipe_Storage[Product_No] will now point to the element in the Recipe_Storage array as per the value present in 'Product_No'. And the COP instruction will now copy New_Product_Name to .Product_Name. The first COP instruction you have used will write to whole of Recipe_Storage[X] (the UDT). In case of the second COP instruction, you are trying to point to an array for .Product_Name, this tag is a String type tag also is not an array, which is the reason the instruction is not getting verified.

Hi, Where can I get more information on PCCC and ASA as well? I use a tool that employs PCCC as well as ASA. The tool defines ASA as a new (?) protocol. Used for Logix platform. My job is only to use the tool for purposes it was designed for, but would like to have more details on PCCC and ASA. Any help would be appreciated. Thanks in advance.

Hi, I have started working on creating some Add-On instructions (AOI) in the RSLogix5000 for CLX (V16) for one of our projects. I am finding it a very convinient feature that will help reduce repeatative programming. However I have some doubts regarding AOIs....... Do they get scanned as a regular instruction? Earlier I have worked on Schneider PLCs (Premium, Momentum) but never created and used DFBs, except for the Premium PLC redundacy DFBs. I remember reading litreature regarding DFBs used in these PLCs, saying that the DFBs would increase the scan time of the processor. Agreed...the code developed to create the DFB would also take some time of the processor for execution. However, how much would a DFB or AOI make a difference to the scan time so as to affect the process controlled by the PLC? I plan to use numerous instances of the AOIs to avoid repetative logic and increase reusability. I have been unable to get any convincing litreature on the AOIs of RSLogix5000. Any help would be appreciated. Thanks in advance.

Are you using the MB1 driver used with Intellution products (iFix..)? If thats the case, then you wont be able to communicate with the Compact Logix platform. This is because the Logix platform does not have direct memory address as in other PLCs. For instance, your tag Mod_DataHoldReg4[1] refers to a memory location in the PLC memory and it will not point to 40001. The Logix platform uses the PLC memory as C or VB would use it. A tag defined in Logix is used directly and its memeory address is not. So, you wont be able to address the memory locations in CompactLogix using something like MB1. One way to do it is OPC. Use any OPC server/client like Topserver or IGS (over TCP/IP, for which you will need the L32E or L35E processors). Hook it up with the RSLinx OPC server to fetch and send data. This way you can use to communicate CompactLogix with SCADA or any other OPC compatible product. This will save you the Prosoft card, but you will have to invest in OPC.

Hi, I did not know where to post this, so I have posted it here. I am looking for details on Boiler/Furnace burner management systems. Especially for coal fired boiler startup using oil or gas. Every search turns up the Honeywell/Fireye FSG systems. I am looking for details on the startup concepts since I need to develop the system using PLC. Any help will be appreciated. Thanks in advance.

Hi, Could anybody give me the details on the following card for ControlLogix: 1756HP-GSP I was unable to locate any information on the RA website. Any help would be appreciated. Thanks in advance.

As Crossbow has said....those are the methods you can use for communicating to a PLC. I still think ethernet to serial converters are the best bet! Please see the uploaded file for details, uploaded from the telemecanique website. I hope this solves your problem! transparentreadyethernetgatewaysproductdatasheets_referencespresentationcharacteristics_en3.0_48404.pdf
