  1. Yes the PLC is in communication with the drives right now, all via the embedded ethernet and all through ethernet switches. Once in RSLogix5000 i was able to add the new moduels to the Ethernet tree, assign the IP addresses and then use the embedded I/O to send a run and stop command to the drives, i believe there is a bit that i have recently discovered that is a frequency display (will give the frequency that the drive is running at) so i could use this for the display however it is the PLC programme that is holding me back in terms of what function blocks would i be looking at to display this information on the screen, i assumed a register or move command that i would give a tag name to, but this is what i am not sure of. Its the issues with the PLC programme to show the current speed and input a new speed, tying them together through the PLC programme is the issue. Thank you Dan
  2. Hi all, I have one of my first jobs using an AB Panelview Plus 1500 screen. The job is to connect a CompactLogix (L36) Panelview Plus 1500 and 34x Powerflex 525 VFD's all over ethernet switchs (AB Managed switches) I have had the system working but now my client wants to add some HMI screens which would allow a manual start/ stop function for each drive and a display to show what speed each VFD is running at and a Numeric input button, of some sort, to allow the operator to add a new frequency and change the speed of that VFD on the screen rather than having to open the control panel and change the VFD parameters. I am very new to Allen Bradley and have sorted out the basics of the PLC programme and the HMI but now need to know what i need to add to the screen to allow me to change the speed and view the speed the drive is running at and how i programme the PLC to do this? If anyone can help that would be great, thank you. Regards Dan

    Theres no chance you may happen to know what that post was called at all?
  4. PLC's for Beginners

    Great post, thank you very much. Right now i am in college and have a digital electronics lesson in which we have just covered truth tables, boolean algebra, etc. Thank you ever so much for the advice, i am going to search it now. Regards Dan
  5. Hi All, I have been using Mitsubishi FX Series PLC's as part of my job now for the past 2 years and i would like to think i can use them fairly well (for the applications that i need them to do anyway) however the company that i work for has now a 'branch' in the Far East and i am looking to enhance the PLC skills that i have as well as learn as much as i possibly can. What i am looknig for is information about PLC's for beginners. i know i have been using the FX for a few years but I think that their must be so much more to do with them as well Allen Bradley and Siemens PLC's. Basically i am looking to further myself in PLC's as i want my future to be with them. If anyone has any advice or any links or PDF's or anything i would appreciate it. Thank You Dan

    Thank you for getting back to me with these answers, i will take a look at that link tomorrow at work as i have a little program that I have to start then so hopefully i can use this to my advantage. Thank you
  7. PLC FXON STATUS

    I agree that the keyboard shortcuts do make GX Developer a simple program to use. Also in reply to the main question I would look at getting an FX3G to replace the existing.

    Hi all, I figure this is the best forum that i can choose to ask for help with starting out with PLC's. I am 23 years old and have for the past 3years been designing control panels and systems which at times incoporated PLC's. I have now started to programme them, which has mainly comprised of Mitsubishi FX Series type PLC's. Lately i have written programmes for the new Siemens Logo! intel relays. What i find sometimes is that when i have been asked to write programmes for systems that i never seem to know where to start and when i do i question whether i am starting the programmes correctly. Is there a structure that anyone sticks too? I realise that its not so much a big deal with certain programmes but I want to create a check list of things that i can tick off and know i haven't over looked anything. I do admit to getting kind of nervous when i am the last person on a project and if the system doesnt work then it points to me, i will overcome these nerves in time and when a little more experience comes my way. I just want to know the basics to automation and plc's and i believe if i know this then i can build upon this and look into becoming the best plc programmer that i possibly can be. I tend to aim high and so if anyone can pass on some information to me reading material, general advice, etc? that would be very much appreciated. Thank you for your time Dan
