I'm currently using a Micrologix 1400 BBB and two of the HSC counters wired to 1 prox sensor to count machine cycles. HSC0 counts every cycle and HSC1 counts only when certain conditions exist. I found this setup easy to use and the ladder simple to program. I would like to know if a similar setup could be attained with using an 1100 processor with only 1 HSC. I want to be able to use long integer or real files to be able to count over 8 segments without complex logic. Can this be done? Thank You, Lou

I think the PVc300 uses real data, not sure on long though. I'll find out when it comes in. Lou

Hi, I'm setting up a micrologix 1200plc and panelview 300 to do batch counting on a machine. I need to be able to read/write counts just over 1 million. How would I address this in logic? Should I use the HSC? Lou

Hi, Is there a way to get past the "PROTECTED" access restriction on a 1747-L524 PLC without wiping out the program? It's old and I don't have the original program nor is the company that made the machine in business anymore. Thank You, Lou

Thanks. I was going to do just that after pondering it over last night. Lou

Hi, I posted this on another forum with no results. I have a Micrologix 1500 with an HSC module and two identical encoders in which one is downstream from the other, I need to keep the length readings to within 2" one way or the other. I have attached the program and as you can see in ladder 2, rungs 2 thru 5, I have the encoders set up and calculated for correct length output, it has been tested and functions fine, however if it falls outside the 2" range, I need a way to set a bit. If you check rung 17, you will see logic I added in an attempt to accomplish this, but I haven't tested it and I'm not sure if it's correct or will work. Any help is greatly appreciated. BTW: speed is constant. Thank You, Lou WALL LINE 3 9_24_13 PROJECT.zip

Hi, I have a question I asked on other boards without success, so I hope I'll get assistance here. I have a 2098-DSD-HV100X Ultra wired to an Automation Direct incremental encoder #TRD-GK2500-RZD with a 3.8" wheel. I'm using a Parker linear screw actuator #ETH100 with a Reliance servo motor #F4075R-HOO-AA. In Ultraware, I get 15785 pulses for every inch of actuator movement, the book on the motor states it has 2000 lines and the encoder has 2500ppr. The encoder measures 12" per revolution. I'm using this setup for a rollforming line which the encoder wheel contacts the material to be tracked going into a shear which is attached to the actuator and when the correct length is reached, the actuator moves the shear die with the material till the cut is complete, then the actuator returns to a home position. What I need to know is how, with this information, I can figure out what the load:motor ratio should be in Ultraware under the auxiliary encoder setting. I need to track the speed of the material through the roll form. Please advise. Thank You, Lou

I want to, but I'm limited by the ML1500 PTO profile. I guess I could try to increase the PTO frequency, lengthen the accel/decel times, and use gearing to slow it down to meet the application, but then I'll still be pulsing faster rates, just with longer accel/decel periods. Would this be effective? Thank You.

Ok. I have done this set-up a few times and have adjusted parameters manually to suit the applications before. I read the slew rate effects the acceleration performance. I currently have it enabled at 4000rev/s2. Is a slew rate necessary when following? Thanks!

Hi, I have an AB Ultra 3000(2098-HV100X) servo drive that I have set up for step/following mode being pulsed from a Micrologix 1500 PTO. It's connected to an AB F4075-R-HOOAA motor that is used on a 32" wide press feeder that has 2inch pinch rollers and is mechanically geared 7:1. I have this setup on a few press feeders with no problems, however, this current feeder is moving very heavy material and constantly getting an error code #23. I know I'm probably going to have to step up to a larger motor, but the manual mentions checking the tuning. I did an autotune. My question is, what parameters should I alter to limit the frequency of the motor thermal error? What other things should I try? Thank You, Lou
