  1. Need help with GX Developer

    It called syntax, please put a space between T1 and the K100 and try again. Ot type in T1 and then select the Edit button?
  2. Need help with GX Developer

    As previosuly stated, a timer instruction is a coil with the definition T2 K100.
  3. Modicon 984

    Geez, a 984A, B or X?  I worked on those in the early 90s.  I remember them being "hot swappable" as long as it was a one for one replacement.  I think there were exceptions for some specialty modules.  I think I used Concept once.  This is the dark ages, we used the old Taylor MODSOFT running in a MS-DOS or WIN 3.0.  Of course, before that we have the oscilloscope suitcase for programming on a 4 inch CRT.
  4. Need help with GX Developer

    Assuming you are talking about the highlighted rung and the coil element with the M1. Timers start with a T??? and must be followed by K???? or a constant to define the preset value.
  5. Ethernet IP

    WIthin RSLinx, I think you can right click on each ML110 and check all the Ethernet port settings including subnet masking and default gateway.  Might be an issue there. You could post both programs and someone will take a look.
  6. Constant Firmware Changes

    Sounds like your programmer needs to up his firmware and his game.
  7. It's udts imbedded in other udts that are difficult.  You have to drag and drop the imbeeded one first, then the other.  Hopefully, it's part of an AOI, then do the export/import thing.
  8. He's talking about User-Defined folder having only an import capability. Each individual udt has an export capability. But I would rather drag and drop.
  9. If the switch above the "Data Station" was a manged switch, then port forwarding could be configured or "aliased".
  10. Good to hear that Kuka KRC4 has CIP Safety.  My experience was with KRC2 and don't remember that being an option.  We did it the old fashioned way, hardwired through the Safety Board. To echo Panic's statement, I've never found any EDS files for Kuka.  Repeated attempts with both Michaigan and Germany Support Groups came up empty.  But that was probably 7 years ago.  Might be worth asking them again. One more idea is www.robot-forum.com.  They have forums on a per brand basis.
  11. Report Button

    Hoping y'all find a solution soon!!!
  12. Configure Cisco Catalyst 2955 switch

    Seems like you need visit Cisco's website and download the Cisco Network Assistant and then read the manuals.
  13. PanelView+ users and passwords

    I had a customer that wrote a 128-bit encryption code routine, but still at some point you have to "compare" to something in the tag database that will be visible by Maintenance Staff. The source protection of the AOI is a possibility, but then someone has to be the gate keeper of that file and kept out of "others" hands.  You'll have to use local tags, but not sure if or who can view the local tags. FactoryTalk Administration Console is an idea.  I have a customer that we developed a proprietary and patented program.  With enabled security, we secure the various PLCs (CompactLogix in this case) to both a specific Windows User and to the Computer Name.  We maintain a seperate VM, just for this customer, to prevent even opening the application or the program.  But I'm still faced with customer requests to modify passwords at various sites (I have roughly 140 sites and about 225 systems) but still based upon Windows Usernames. Same procedure, I upload, restore, change user pws to something (along with Windows rules for last three used pws), create mer and download, then store the mer back to a "secure" project file on our server.
  14. There is a migration manual for converting the SLC Rack into a remote IO (via 1734-AENT).  In that document it specifically tells you which modules in the SLC world can be used and those that can not be used. YOu would probably need to add and program the Compactlogix version of the Prosoft module to it's local rack.
  15. PanelView+ users and passwords

    Joe, for me, the short answer is no... Essentially, you are trying to move away from Windows based user id's and password management.  You'll need logic and database in the PLC and then different objects in HMI to manage this. If you can and want to maintain the Windows User IDs, then your procedure would be upload the mer and restore it to a project, make changes, create new mer and download. We've also done all the user name and password management in the PLC, but you say "they" don't want anyone to to have access to the passwords, so that's a no go. We have done some logic "rule based" the calculates a new password everyday, but even that has to be stored in the PLC database.which could be seen by Maintenance. Maybe it's possible to create a similar "rule based" scheme in a macro, not sure how at the moment, that would store the passwords to internal memory tags.  The minor concern would be that if someone had the program, they could figure out the password if they read and understood the macro. Additionally, even internal tags can be displayed on a screen.  Maybe an admin access only screen. Longer answer is I'm not aware of a full-proof method.  Maybe some other ideas out there.
  16. SLC500 f(x) 10-breakpoints

    Differences in platforms and about 30 years.  And I'm a brute force programmer, find it hard to debug indexed logic.
  17. SLC500 f(x) 10-breakpoints

    Ok, so the FGEN is only available in structure text or function block, but after reading, I think it describes exactly what I originally stated about the comparisons and then SCPs x 9.   As always, Michael is much more eloquent then I.
  18. SLC500 f(x) 10-breakpoints

    I don't think they gave him a formula and stop calling him Shirley. Basically, by breaking it into more segments, one can begin to assume linearity.
  19. SLC500 f(x) 10-breakpoints

    I'm not aware of a function generator or breakpoint set type of instruction within the SLC. Can you descrbie the data as a formula?  If so, then use the CPT. If not, then you'll need to define 9 rungs with comparison logic for the temperature, then use 9 SCP to get the value of kPa.  The assumption is that each segment is linear.
  20. I can echo Joe's comments.  The Red Lion is a wonderful protocol converter and price effective.  It's somewhat limited on the HMI side, but then again the old PV wasn't a spaceship.  You won't lose any HMI appreciable functionality moving to the G3.
  21. Several places on this site for buying PV550.  Rockwell will continue selling PV+6 for a couple more years.  Then these guys will continue to find, refurb and supply PV+6 for years.  Keep in mind that you are continuing to use 30 year old technology and wonder why you are having a hard time maintaining the system and finding spare parts. You probably need to ask yourself some questions.  How long have these machines been running?  How much longer will they need to run?  Do we need to consider a complete control system migration to latest and greatest technologies to extend the life cycle?   You can keep pinching that nickel while $100 bills are flying out the door.
  22. Up Down Counter (Mitsubishi FX1N)

    Yes, the output will turn off any time the D10 is less than D20 and turn on anytime D10 is greater than or equal to D20.
  23. Dashboarding Recomendation

    This question has been asked and answered dozens of times. Consider  AdvancedHMI’s HMI package (free) www.advancedhmi.com and many others. You'll need to determine the number of, types and comms protocol involved.   
  24. Up Down Counter (Mitsubishi FX1N)

    Probably, do not use the output or done bit of the counter.  Rather do comparison on the accumulated value of the counter and the preset.
  25. GE Fanuc Series One - Counter Instruction (?)

    Looks like the German version of the counter instruction.  Maybe someone in the forum from Europe can define the inputs and outputs for you.
