    Rexroth Hydraulic

    TY. Rexroth actually called me back, and we are on the route to find the right thing. Waiting for a shop to open to call them and get an idea of when I can get this, and what else I will need. I've never changed one of these before, so I might sub that out. I don't want to dump 150 gallons...

    Rexroth Hydraulic

    I had another vale go out on the beast, although I programmed it in the PLC, I know little of hydraulics. Here is the value Part number from Rexroth: 4we6d52/ag24ndav The diagram is here: https://photos.app.goo.gl/hoXiUgd1zxccNB7K2 It controls one ram. I believe it's a 4 port, 2 position...

    30mm blanks

    Thank you! A closing button. That's an obvious name for a panel blank or a hole plug. Thank you again!

    30mm blanks

    I'm looking for something bigger on the outside, flat, with a seal threaded which screws on from the inside. I've seen them before, but can't find them. I looked at both posts and I didn't see a method of attachment...

    30mm blanks

    I have a control panel with the 30mm holes with the notch. Pilot switches/lights. I need a blank to fill in a spot where there is no switch. My google searches are coming up with blank plates with a hole in it for labeling... And suggestions?

    Need to find a replacement valve for Hydraulic Ram

    New controller I put in it. Click PLC. Thanks for the help, some guy in Utah called me back, he had the coil part in stock. Amazing... $28.00 + shipping.

    Need to find a replacement valve for Hydraulic Ram

    Thank you, doing that now. I'm not sure why they have 2 valves for this, where other things on this beast use 1 valve for both directions. This valve controls the flow which goes into another hydraulic -> hydraulic valve, so maybe that's why. In the picture, this valve controls the flow...

    Need to find a replacement valve for Hydraulic Ram

    This valve is from the 70's. It takes 24 volts DC, and it opens one way. There are 2 valves on the Ram, one goes out, one goes in. Same plate on both. The electric part of it shorted down to .6 ohms, so it blows the fuse, therefore I disconnected it and have a human running it manually with...

    Multi function LED control

    int main() {int c; cout << ++c; return c;} Then stuff like that pops out.

    Multi function LED control

    This is what I wanted: LED = Home AND NOT (Ignore AND (NOT Flash)) No parenthesis in PLC, so I did [Ignore]--[/FlashBit]--->(OUT C5) [Home]--[/C5]---------->(OUT LED) It's different going form C/C#/Delphi to this...

    Multi function LED control

    I'm trying to drive an LED so that it shows 3 different states. This thing goes in a circle, and there is a limit switch at the bottom. (Hydraulic motor spins a gear) When you press Start (X1), the motor runs (Y1) until the limit switch (X2) is hit again. (Can't use rising because of bouncy...

    PLC and moving a Ram between two limit switches, and back via momentary switch.

    Got the parts Friday night, started tracing wires and cut out old series one controller Sat morning at 6am. Fully operational by 4pm Sunday. Smooth fast first PLC job.

    PLC and moving a Ram between two limit switches, and back via momentary switch.

    Here is a picture of the machine. https://drive.google.com/file/d/0B882DaQ0eI-vTjN3eXVvYTdxWFU/view?usp=sharing 100' long is correct, maybe only 25' wide. Definitely 25' tall. I didn't measure because it's irrelevant.

    PLC and moving a Ram between two limit switches, and back via momentary switch.

    All the C addresses are bits. Anyways, unit just showed up via Fedex, time to play. Thanks for the tips/heads up/help. I'll update post at the end of project with results/pics. This machine is over 100' long, 60' wide and 25' tall.

    PLC and moving a Ram between two limit switches, and back via momentary switch.

    Are you saying I should Set (forward, back), then just clear each bit as the task is completed?

    PLC and moving a Ram between two limit switches, and back via momentary switch.

    LS = Limit Switch. SW = Control Panel SW O = Physical Coil/actual output. I forgot to clear run, but does this seem logical? (unit is in the mail to me now, can't test) Is this the general pattern for such a thing? Does have an error (like it will cycle over and over right now)....

    PLC and moving a Ram between two limit switches, and back via momentary switch.

    Perfect, didn't find base index for that, but now that I know all that is there, I can find it. Exactly what I needed. Has nice simple example programs showing logic control, flow for simple tasks. Thanks a bunch, Charles

    PLC and moving a Ram between two limit switches, and back via momentary switch.

    I've got the ram moving forward to limit switch (based on physical user switch), then when switch is reversed, ram goes back to starting limit switch, as long as user holds in the switch. [ ]-[/]-( ) Easy I'd like to automate this so a momentary switch makes it latch, drive to limit, pause...
