  1. Emerson (GE) memory map data types

     I've always had this Allen-Bradley memory map taped on my wall in my office. It used to be handy to use, until I remembered al of the prefix letters for each data type. Now I am using Emerson (GE) the old proficy software now called PAC ME machine edition. Now I'm finding it's about impossible to find the data type list amongst the thousands of help files, videos, ect... it seems like a simple thing to find, but I'm not having any luck. They use I and Q for regular inputs & Outputs, but there are R files, M files, S files, N files, G files, ect.... this is old-school PLC software that doesn't use tag names.   Is there a steadfast rule for each type, or can they be used for any type of data? Dazed and confused...  
  2. Currently have NX PLC setup as an OPC UA server and an OPC client setup and communicating.  The issue is only tags that do not have a Data Type are showing up in the OPC client.  I have 2 separate OPC softwares connected to this plc through OPC UA and both are having same issue.  If I setup the OPC as a polling service, then all the tags show up as expected.  Does anyone know if this is a known issue with Omron and their OPC UA server, or is there something that I am doing incorrectly (possibly a setting within Omron that I am not aware of)?
  3. I'm editing an old program for a customer that has a zillion user-defined data types. Scrolling through the list trying to find a specific type definition is taking way too long. Is there and easy way to find a specific data type definition? It would help if I knew how to collapse the view so I don't have to scroll through each member of every type. There doesn't seem to be any right-click menu items that would collapse the view.
  4. Hello, I'm using RSLogix 500 application for LAD programming. I would like to convert the float data type to integer data type and vice versa. I tried with the COP instruction as some had mentioned in other forums, but it was not working. So any suggestions on solving that issue would be helpful.
  5. 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
  6. Omron Learning Curve - DATA TYPES

    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
  7. Hi friends, I am a little new to WinCC. I am using a WinCC RT Advanced license within TIA portal v13.1 I need a little help in my current project as described below. I am attempting to create a faceplate of a solenoid valve,, The "Valve" is a user-defined data-type with the following 4 elements 1. Cmd - or command. - Bool 2. Cls_Fb - or Closed -Feedback -Bool. 3. Aut - or Automatic Mode -Bool 4. FTC - Fails to close -Bool. I tried the following procedure as described in TIA portal help.. Method -1 1. I created a User-defined data type called Valve comprising of the above 4 bool elements. 2. In the graphics I made a image of solenod valve with one rectangle (solenoid) and one polygon for valve body. 3. Under the Faceplate Properties (See figure attached) I inserted a property ang gave it the data-type Valve as above. However, when I drag a property from the 'Contained objects list' to the interface side, it is not getting substituted. such as the Rectangle_1 's background color I try to associate with the interface property Valve.Cmd. It does not get assigned when dragged. Since this does not work I tried another approach, Method -2 I attempted to declare a variable tag of UDT type 'valve' in the faceplate's tab Tags. I found that it is not possible to declare a local variable of User-defined types here. Please guide me how to proceed. Thanks for looking in and best wishes for your success. Regards, Raj S. Iyer
