Hello, With an output properly fused on inductive loads should you also connect in parallel a resistor(15kw,2w.)? Thanks, Jeff

Something that could help is on this pneumatic cylinder meter the flow in the cylinder not out or a surge can occur. Thats my 2 cents.

Hello, I have read the manual and applied what I read to setting up an HSC in a 1746-L532E processor and I"m having trouble getting it right.If anyone has an example of this with multiple presets I would be in your debt. Thanks J.Purnell

Thank You very much.

Thanks for the tip. But I'm using a HSC1 would the same logic still apply as seen in the HSCE2 set up download?

Hello Everyone, I'm trying to set up HSC in a 5/03. Does anyone have a sample of this logic or any suggestions on how to do this. I've used this in a MicroLogix 1500 but of course the HSC's are already set up for you and you simply write a HSC Load and away you go. I have an idea on how to do this but I'm in pickle and I need to know ASAP. I have the publication on High Speed Counters. Thanks. Jeff Purnell

Thanks for the tip. I'll do some research in that direction. Jeff Purnell

What I'm looking for is to store a group of numbers (up to 200) to a location in the PVPlus to be retrieved thru user control such as a move command or load command to Micro Logix LRP controller Interger file N:7. I was trying to understand how the receipe option actually could work for this. Thanks

Hello everyone, I've never used Panel View Plus I'm wanting to know if you can create multiple files to store up to 200 intergers each? Thanks Jeff Purnell

This the logic from one station which produces the bottom half of a pallet.1ST_DH.RSS My logic here is simple, HSL a interger in a counted step, once a number is loaded pulses are counted up to the preset number, then stops, does a function and HSL a new number and so on until the max length is reach.Then reset to zero via prox.But watching the HSC acc it will always overshot the peset by around 10-15 pulses.I was thinking I could minus the overflow from the next number in line to try and keep accuracy.I've tryed a few math conversions but just can't get past a good way of doing it yet.Any ideas? Thanks

Answer to your question is: (x100us) Max.= 36 Min.= 10 Avg.= 30 x100us No, the overtravel is throughout the coarse of the run. Yes,I'm using the built in HSC. Just so you know this machine is making Wooden Pallets and was controlled by a proximity switch sensing a cam on a timing chain to achieve the stop positions. Also this machine used all ice cube relays and 1sec. timers. So in trying to upgrade to PLC control I wrote this program based on using existing hardware with the addition of a pilot operated check sandwhiched under the dirictional control valve. The conveyor is already two speed controlled going high speed between products then at slower rate during assembly.This system produces around 2000 units in a 8 hour shift so, around 20 units are effected by this overtravel issue it's enough that I would like to address it somehow. Thanks Jeff Purnell

Conveyor is moving in only one direction @ 52 fpm. Everything is a new component. Yes, it is a Parker valve all ports closed center position . chain. Yes, on all parts. The temperature is maintained at 120 degrees during operation. Anywhere from dead on up to 1/2" overshot. This would equal 11 pulses. (22 pules per inch) Using a BEI Encoder 550 ppr.

Hello everyone, I have program which controls the moving of an hydraulic driven conveyor in increments that are setup by operator interface (panelview 550 k5a5) in tenths of an inch. At present this system works very well (most of the time) but like all of you I desire more from my products. Here's a brief example of how it's measured out: 1st. a numeric entry is made. there can be up to 24 different positions entered for any new part chosen. 2nd. a math conversion is made via logic and converted into counts that are loaded into the high speed counter.Each time this machine reset for a new part to be made it moves to a set point, stops and does a function and moves there after in a sequenced pattern preset via interface.3rd. At the end of each new part made logic stops the part and positions the piece that is placed. Just so you know I'm measuring in an step method. (1.5-1.5-1.5------6.0-1.0----3.0-1.0------6.0-1.5-1.5). The issue I'm experiencing is sometimes the conveyor seems to move beyond the preset points and the results are the new part has moved beyond it's desired position. NOT GOOD! Now the question. What logic could I use to minus the overflow of stopped point from the next set point so the conveyor will respond accurately?Also, What would be better the step method or conventional method of measuring? Thank you all for any response to these questions. Jeff Purnell
