  1. Panel pictures

    Hi Russ, my business's facebook page is a public page so you do not need to have an account to view it. I also have a website, albeit just a domain reserved with a single page with some contact info and a link to the facebook page. Facebook is 100% free whereas to put the same content on my website could cost circa £120/year minimum. As I run my business in my spare time and work full time and to date have gotten work through word-of-mouth I am not too concerned that it may appear as the cheaper alternative. Also I find as time goes on more and more companies are not ashamed to have a "facebook presence". Regards, Patrick
  2. Panel pictures

    Welcome to the forums Marwan. For my stainless steel panels, I use a hole-saw for small panels with just a few cutouts, and for the larger panels I design the layout in CAD and have them waterjet cut locally. If you are just making a pilot hole for a hydraulic punch, then you can get drill bits specially for stainless steel, they are more expensive than standard bits. Also try and drill them at a slow speed with high force. HTH - PG
  3. wire duct cutters

    I also use a circular saw (Bosch) for duct, duct cover, and DIN rail. It has a laser guide and can also cut at different angles, cutting the duct cover at 45degrees makes for very neat looking ductwork

    I have just made a facebook profile for my business, there are photos of my panelwork on there; http://www.facebook.com/pages/Matrix-Engineering/142895319108866
  5. Thanks Ken, IO so far is: Main Panel (1) 1734-AENTR x 1 1734-OB8 x 3 1734-IB8 x 2 1734-OE2C x 0 1734-IE2C x 1 1734-TB x 7 Whey (2) 1734-AENTR x 1 1734-OB8 x 3 1734-IB8 x 2 1734-OE2C x 1 1734-IE2C x 3 1734-TB x 10 Towers (3) 1734-AENTR x 1 1734-OB8 x 3 1734-IB8 x 2 1734-OE2C x 0 1734-IE2C x 0 1734-TB x 6 Havn't counted required CTM and VTM's yet... Do I need RSNetWorx EthernetIP to configure rack optimisation? (Going for Logix5000 Lite as we shouldn't need CLX in the forseeable future). I shall download the selection guides you have suggested and read up. Cheers
  6. Russell, could you expand on what you mean by "more than a few I/O"? I am currently planning my 1st CPX project which should have no more than 100 IO (circa 90% digital, 10% analog) using a L32E PLC with 3 Point IO locations...
  7. help

    Note the starter software only works with F series Micrologix 1000 10 point PLCs.
  8. Distributed IO

    CLX is a no go as we have only this year managed to get RsLogix 500 standard edition, so I can't see 5000 being financially feasible. Econ EC3-60 is a budget PLC, similar in exterior looks and ladder commands to Mitsi's. £550 for a 60 point (36 in 24 out) PLC, a 3.7" 20 key HMI, and necessary leads. The PLC and HMI software is free. http://www.listo-ltd.com/ This years project was to replace two SLC 150's in the block formers and to upgrade a DTAM on the 3rd to a PV 300, so I tried out the Econ's as a replacement for the SLC 150's (So far so good 38,000 blocks done so far).
  9. Hi all, looking into an in house project for next year. I havn't previously done any work with distributed and/or networked elements, so looking for your advice... The attached file shows an overview of the rooms and what IO/controllers there are. If budget allows room 1 will have a RsView32 SCADA running. This is for a CIP project so not a huge amount of traffic I would imagine nor does it require a very fast response time. I would like to gather some data from the three PLC's in room 2. So what would suit best here in terms of RIO, Devicenet, just-run-a-multicore-cable-option etc? Thanks, PG IO_layout.doc
  10. I have not used PLC5, but can you move the value 3.14159 to a register and use a reference to this in your calculations? For squaring, you can you multiply the value by itself? (3 x 3 = 3 squared) I would try and split the equation into smaller sections...
  11. Questions..

    Some good advice in the previous two posts. As stated, have a go at it yourself, post up the code and we'll have a look and keep you on the right tracks. Also, download Hugh Jack's PLC book here http://forums.mrplc.com/index.php?autocom=downloads&showfile=156 if you are having trouble with getting to know the functions of RS Logix. Remember too there is a list of all the instructions with an overview of what they do in RS Logix. If you don't have access to RS Logix outside of where you are learning, visit the Allen Bradley forum here to download a basic version. (RS Logix10 Pt Starter) Good luck!
  12. Tapping holes

  13. Update; spoke to a local process engineer (BSc (Hons) MSc CEng MIET) who designs the controls/programs PLC etc but does not build the panels. When I told him my background and where I wanted to go he offered to sub contract the panel building to me, which will get my foot nicely in the door as he works for some large firms such as Kodak, and a lot of local firms too which suit me not having to travel too far. Also won an AB Micrologix 1000 on ebay for £12.50... bargain! Going to tinker with it at home to learn as much as I can. It's manual will be the 1st in my E-database, thanks Clay B.
  14. We all have to start somewhere... and I don't design panels, but if I ever do in future I'll now know how to size them. Yes, we learn by our mistakes, but we also learn from those with experience.
