  1. Communication between a Robot and other machines

    All robot applications I work on have a PLC acting as a cell controller (90% of the cells I work on get delivered to Ford or GM and that is their requirement also).  The PLC coordinates all of the machinery and automation involving the material handling, operator interaction (HMI), and safety when a safety PLC is used.  Its much easier letting the robot be responsible for just what the robot is best at - single task motion and controlling end-of-arm tooling.  I find programming automation in ladder is much easier than trying to program automation in a robot scripting language.  The PLC is better suited to handle multiple asynchronous tasks where the robot is more suited for a single or list of sequential tasks.
  2. Logging on to a faulted processor.

    If the program is still in the processor and the fault is only because of missing I/O modules, the serial port may be configured for DH-485 instead of DF-1.
  3. Safety Tags Studio 5000

    No, you have to create a link between safety tags and non-safety tags by using the "Safety Tag Mapping" feature in the Tools pull down menu.
  4. Ultra 5000 drive, Firmware issue.

    When I started to look into this I was surprised that you have to have a different contract for technical support as this product is obsolete as of 2013.  (One of my customers has purchased every ultra5000 he could find in order to support older installations, about 500 units).  So I couldn't find a list of Series verses firmware release compatibility. Sorry I couldn't be of more help.
  5. Ultra 5000 drive, Firmware issue.

    Difficult to see the pic but what series is listed on the Drive's label?
  6. I don't believe this statement is true. I can't find in RSLogix where I can separately configure the ports with different addresses. I hope someone can set me straight.
  7. S5 to an AB plc - hardware question

    With the availability and low cost of the 1769-L16* and 1769-L18* brick style processors with embedded I/O (expandable), I've kissed Micrologix and SLCs goodbye. Except for maybe the 1400, that thing has got a lot of nice features.
  8. RSLogix 5000 IO Mapping

    Assuming you have the project file and are able to open it in RSL5K, take a look at the I/O configuration tree. You can count, or at least estimate, the number of discrete I/O points the project uses.
  9. I've done it both ways and its usually the customer driving which we go. The last time, the machine was running production; we had weekends to test out the conversion, the electricians were used to PLC5s and SLCs, and the customer only had so much budgeted. So, their program has tags that simulate the file structure of a PLC5 and the logic mimiced the original program. A couple of times before that, the whole machine was being re-conditioned. It wasn't going to be used till sometime in the future, and a new machine would have been too expensive so the budget was more relaxed. They got a redesigned program with all of the bells and whistles.
  10. Any word on Rockwell's Next Generation PAC?

    "I do not know of any other company's software that you have to have multiple versions installed. Every other software program I use can at least open up older versions and convert them." RSLogix does that. But major releases have to do with hardware support, the firmware running in the CPU. Excel and AutoCAD do not and that is a huge difference. Have you ever been part of a team that has to support an embedded system and handle new product releases that are driven by changes in the hardware? You'd find that the method RA is using makes sense. Again, major releases have to do with new hardware offerings. If the hardware can't support the new software features, conversion doesn't work to be backward compatible. Re-read your original post, "I am surprised how little effort Rockwell has put into making their software more user friendly." Thats a user interface.
  11. ET200 S addressing I/O's

    If I remember correctly (been a year since I did a Step 7 project) addresses are assigned in the HW configuration.
  12. Allen Bradley 1756-L1 can´t go online

    I believe you are right. You should be able to use one of those other CPUs in a open rack slot to get across the backplane too.
  13. plc programming

    I write an FC for each (or an FB if I think the code can be used for more than one component, like cylinders or motor control). For me, it keeps it manageable. I can debug it, bless it, set it aside, and move on to the next.
  14. Any word on Rockwell's Next Generation PAC?

    I was curious on who the high-end competition was for larger machines you are refering to? Just a thought on backward compatibility: So, for example, you think that RA should go back through all of the old versions of RSlogix and create support for the Kinetix 5500? Should we expect Microsoft to go back to Win286 and add support for Firewire? Or USB 3.0? They just dropped support for WinXP, should they have kept it up to date for the next 100 years? Not trying to start an arguement but no companies I know of do that. There is a valid reason why software companies, like Rockwell and especially Siemens with Step 7, don't change their user interface drastically. The people using them want, for the most part, a seamless change between versions so that they, and I mean me, don't want to spend precious time I could be spending on billable hours re-learning something new PLUS remembering how the previous versions work. Just my $0.02
