    A-B pass word question

    or you could just use the code 22865625 That will crack the SLC password oops, I wasn't supposed to tell :|

    Schneider Modicon Quantum PLC

    Scotty, 95% of my work is AB, but I think Modicon Concept is the best programming tool after using AB for so many years. I recently did a large project, which I developed some fantastic Function blocks which made the job soo much easier, and are reusable on any future projects. It was my first...

    Five Rung Logic

    I have not heard of this "5 rung logic", but I use a similar concept, which is simple to follow, but is considerably more than 5 rungs. The main idea is to standardise your logic for any given project. It is important to have a standard tags and memory allocation that is simple to interface...

    PLC 5 Scanner/Adapter Help

    I haven't heard that term in a while. That would be Allen Bradley PLC5/15 or PLC5/25 if my memory is correct. I have not looked at this isue for at least 10 years, but I will explain what I remember. This is mainly to do with the configuration of the Remote IO port. Scanner Mode: The idea is...

    a Quick RS Logix question

    Having spoken with people at Rockwell on this very subject, it seems they are never going to have online editing ability for micrologix range. They are more keen to push the CompactLogix range as the slightly more expensive better alternative with online editing ability. Having used both, I...

    a Quick RS Logix question

    Yep, Not an issue. If you select EDIT->Verify Project, they will be both the same. The number next to SOURCE B is all that matters. The other number is just the last value. If you are working online, you can not change constants in micrologix. Go offline, edit the value next to SOURCE B...

    Flight Simulator PLC Control

    SLC system would be very expensive, and not all that fantastic. It looks like a reasonabley large system. Too large to place IO in the computer. I would be inclined to go for a control logix over the SLC, as the mathematical abilities are way more advanced. It also has advanced interupt...

    Messaging between Siemens S7 and AB Control Logix

    I don't think it is possible. First up, I am not a siemens expert. A company I do a lot of Allen Bradley programming for recently set up an interface between their Allen Bradley and Seimens system. They used a lone S7 processor on ethernet to the siemens network to act as an interface. This...

    PC based industrial control to replace PLC

    If you want robust control, use a robust industrial system, not a PC. What happens when your PC locks up, or crashes?? How can you possibly rely on a PC. A PC is OK for SCADA, as it is only supervisory, does no actual control. So when it locks up (which happens regularly) the PLC continues to...

    prosoft technology modbus card for the AB PLC5

    No matter how much work I do on the prosoft modules, I still get confused when using them. Your problem sounds specific to your case, so would probable require Prosoft Support to examine your logic. I would contact my Prosoft distributor.

    Subroutine Use

    Point taken jlada, but I do have a solution to the comparison instruction. I use one intruction (2 power STEP) to a word. This then gives a word where each bit represents the step number, ie bit 0 is on for step 0 or if sequence is stopped. Bit 5 will be on for step 5. So I don't actually use...

    Subroutine Use

    I would agree with FrancisL. I have been programming PLC's for 20 years. I have been down that path of using subroutines like steps in a sequence. In the end, it becomes more confusing and the result is generally not as good. The simplest method (put simply) is to move values into a STEP...

    Need Help w/ Copy Instruction

    The length is the number of destination elements. So if the destination is a word, than the length refers to words. If the destination is a timer, than the 1 length = 3 words. In your particular example, it is words.

    How do I capture elapsed run time?

    On every project I program hour run meters for every motor. Using the real time clock is not the way to do it. The simple way, is use the RTC:0.sec/0 which is the LSB for seconds. Each time it changes produce a pulse. This is a reliable 1 second pulse. You could also use S:4 if you don't have...

    AB 1747-AIC

    rubna, That will work to a 1761-NET-AIC, which is why I suggested it. It will not work to a 1747-AIC, as it has an RJ45 RS485 to DH485 interface. Therefore you need to convert RS232 D9, to RS485 RJ45. Changing the config to 485 is still RS232, but in DH485 protocol. You still need to...

    AB 1747-AIC

    I don't know . Try it. If it does not work, there are Allen Bradley alternatives. Try a 1761-NET-AIC instead of the 1747-AIC for you DH485 interface. It has 2 x RS232 ports on it. 1 DIN, 1 9pin D. This is the usual method for 5/05 to DH485. Or you can use a 1747-PIC to interface from the SLC...

    cable colour?

    My answer is to someone who is not using rules and wants to know the safest way to break them. I am by no means condoning this sort of behaviour, I am just stating the facts. Mainly that if you were to use the green/yellow for anything other than earth, it should be neutral as an MEN system...

    cable colour?

    The reason is most cable will come with a green/yellow for earthing. For a 3 phase motor, usually a neutral is not required, so use 4 core cable (3C+E). If you don't require the earth, then this core would be wasted. If you have no rules, you could use the green/yellow for the Neutral, as it...

    cable colour?

    You have not said where the installation is, and requirements may differ in other locations. In Australian standards, Green/Yellow must be exlusively used for earth. If you see a green/yellow wire, you should be able to safely assume that it is not live. It would be illegal to use it for...

    Mitsubishi F1-20MR

    The old Medoc sotware should work with that PLC OK, but you will require an interface. The old F1 PLCs need a special interface unique to them. Unless you know someone who has one, you will find it difficult to find one. I have seen some internet sites selling obsolete hardware, you might find...
