Looks like you do not just have a fish story there. It also looks like there is life away from work. Glad to see you took advantage of it. Bud

For internal tags we normaly use snap track and snap track tags. If there is not enough room for snap track we use adhesive backed tags. Any external (exterior) we use drive screws or 4-40 self tapping screws. The self tapping screws allow the tag to be removed later if it needs to be replaced. Bud

Nice find Andy, Thank you Bud

Something to try http://www.roymech.co.uk/Useful_Tables/Dra...ol_symbols.html http://www.roymech.co.uk/Useful_Tables/Dra...er_symbols.html

Mike, I also have watched the Tektronix service department do the same (wash with water) when repairing/calibrating the old scopes. Man, do I fell old. Bud

"I know the problem is mechanical (Hydrulic or even Pneumatic) can't you just fix it in the program?" Ever heard this one (more than a hundred times)? Bud

We used to close a counter weighted door. When the door was in the closed position a spring pin held it closed and a few switches detected the door closed. When the machine process was complete a cylinder pulled back on the spring pin and counter weighted door opened (raised). Bud

I just tripped across this cool link with a lot pneumatic drawing symbols. http://www.smceu.com/Prod/WebContent/corpo...ls.jsp#air_line Bud

Toshiba, Satellite with 2 slot PCMCIA (1=AB PCMK card, 1=empty) and 1 Express card slot. No serial port but the USB to serial converter seems to be working fine for now. Also has the normal USB, Wireless, Firewire, Modem and Ethernet. Bud

How can I hook multiple RS-232 devices to a single ControlLogix system?? It does not look like AB has a seperate network card for RS-232. Thanks Bud

Thanks chakorules, nice article. Good use of rung comments. I realy like the "Stupid DeviceNet" comment, but I understand the frustration when tripping across the need for btye swap. Bud

Thanks All. I like the Point I/O method. Multiple ASCII devices (Bar Code Scanner, Communication to a CNC computer (Seimens) and communication to a few Keyence laser measurment sensors). Thanks again for tickling the thought provoking synapses. Bud

Sorry, I can not help out with the shift swing. I work for a OEM that has only one shift but, I have worked in all kinds of plants with all kinds of different shift schedules. While working in these plants it seems the third shift ALLWAYS get the s**T (worst) jobs (work) and gets the blame for all the trouble. Good luck on third shift. Bud

I started working in the coin op in the mid 70's and now still do it on the side. You are right I thought I was King s**t back then (money, good job, girls and all with little education just a background in electronics). Working at a distributor, going to coin op shows and working on the road (bowling alleys, Bars, Game Rooms and every little store that had room to put a game or two in). I think I was a smart RAT because in the late 80's I jumped ship. I had seen a lot of operators dumping their routes, game rooms closing and the influx of the home version games. It is still in my blood. I loved the old EM's because all you needed is to understand relay ladder logic and have a jumper wire, a points (relay contact) bender and maybe a burnishing tool. Funny story, Space Invaders video game at a greasy spoon. Has game sounds no video. Normaly it is a bad monitor or no video output from game board. Opened game CRT was glowing, had High Voltage maybe it just needed the brightness turned up?? No just had to scrape the years of grease and dirt off the front of the monitor and reflecting mirror. Problem fixed!! Bud

Larry, Just because you miss the waxed string bundles. The photos are not of an industrial panel but of a Electro-Mechanical pinball machine that used waxed string bundles. The wires are color coded (no wire tags) and used the fabric style coating. http://i237.photobucket.com/albums/ff189/H...sticBackbox.jpg http://i237.photobucket.com/albums/ff189/H...icPlayfield.jpg http://i237.photobucket.com/albums/ff189/H...ntasticTilt.jpg Gravitar, Bring back any good/bad memories?

Chrysler (Do's & Don'ts) and Ford (VOSS) both require Bonding the ground bar to a unpainted area. Plant Inspectors will look for this. From Chrysler (Do's & Don'ts) Equipment grounding conductors shall be terminated in each electrical enclosure on a common ground bar or terminal strip which is bonded to the unpainted sub-plate. From NFPA-79 8.2.3.3 Bonding of equipment with bolts or other identified means shall be permitted where paint and dirt are removed from the joint surfaces or where the bonded members are effectively penetrated.

Got Milk??

I got the fever! I have panned for gold in Colorado when I was younger. Not at the tourist traps, but in streams leading down from a glacier. It was a lot of fun. A native from the area taught us to go to the old abandoned assay sights and pan the dirt from the bottom of the slag heaps. The gold from the slag (the piles of crushed ore used during the assay process) had settled through the years to the bottom of these piles. Got the fever but never got rich. Bud

I will try it. Thanks again Bob. Bud

Bob, Thanks for the link. Leave it to Solid Works to help out with a revision level converter for AutoCad. OT: I tease the 3D Mechanical Engineers that all I have to draw is circle, squares, straight lines and all on snap!! Bud

Here is a old method. I have used this method but the flatened drawing is a bear to clean up. I think Rockwell ABECAD Knowledgebase also showed this method at one time but I could not find it today. http://usa.autodesk.com/adsk/servlet/item?...&id=2694189 Bud

It looks clean and easy to read. Nice job.

Correct, Long track across the back panel. Yes, Sometimes you can get them out by prying them out untill they "UN SNAP". This is easier using the plastic track. Sometimes they can only be slid out, usealy when using the aluminum track. When the tag is made correctly (correct height) the tag will snap and hold in place. Too big and you fight to get them in. Too small and they slid back and forth and do not stay aligned under the correct componets. Bud

Bob, We use this style tag holder in all of our enclosures to locate the backpanel mounted componets. The part that holds the tag is called Snap Track. This track is held into place by using the adhesive backing or with drive screws. Once the track is in place the tags can be sild or snaped into this track. The tags are 1/2" tall and as long as needed. These snap track tags are thinner than most of the engraved lamacoid tags used for external devices (lights, push buttons, etc.) We purchase theis snap track for our local tag engravers (see attached). Sorry, I do not know who manufactures this snap track but it does come in aluminum and plastic. http://www.rossnoble.com/catalog.pdf http://www.mcsengravers.com/ http://www.ronp.com/ Bud
