Good day, I´m helping with small project and currently i am stuck because of this problem. And I hope you can help me out. I´m using PowerFlex 525 connected with AB CompactLogix 1769-33ER PLC via EtherNet/IP. Connection is working, I can read and write values from/to 525. To configure both devices i´m using RSLogix 5000. 1) First problem occurs after I loaded configuration to 525 and it´s, that 525 keeps overwriting values of Accel and Decel Time 1. It happens when i directly change parameters in Module Properties (online) or after I upload configuration to device. It happens even if i set parameters directly to 525 with its HMI panel. - I kinda get around this problem when i use Accel/Decel Time 2 for Step logic, but if i send direct reference value motor still jump to it and that is not good, especially when changing direction of rotation. 2) Second problem is that I cant get Speed Sources and Start References right. Usually Is working only option 1 and others are not, or they are doing something else that they should. For better imagination this is what i want to do: I have 3-state switch (left = 1 ON(DigIn TrmBlk 02), 2 OFF; center = 1 OFF, 2 OFF; right = 1 OFF, 2 ON(DigIn TrmBlk 03)), In center position I want to control 525 with EtherNet (already working when: Start 1 AND Speed 1 = EtherNet/IP). In left position I want to control motor directly with Drive Pot and In left position a want to start Step Logic (which i have already set) - Funny thing, If I set Start 1 = Ethernet, Speed 1 = Step, Start 2,3 = DigIn, Speed 2,3 = Drive Pot then in all three position motor goes in Step logic.. Or when i get left and right position working then Ethernet is blocked.. and this kind of things.. I Attach print-screen of my current settings, if you need something more just, tell me. Thank you for your time, and I hope someone will be able to help me.

Can any one help? I am trying to write logic to collect data off a Control Logic controler using V.20.03 Logix5000 software. Attached is a copy of Time and Date logic. I there an easier way?

Hello all, I am experiencing an unusual (and what appears to be an unheard of) behavior in my CompactLogix L18ER controller. I am setting the date/time of the controller from my work station, however when I GSV WallClockTime, it is reporting 4 hours different. I have asked our local resources as well as done some forum and knowledgebase searching without result. Has anyone encountered this before? Attached is a screenshot of the controller time vs. the wall clock time. This isn't mission critical since it can be manually adjusted however I would like to understand what is taking place that would cause this behavior. Thanks!

I'm very much a novice to plc programming. I've dabbled in years past with Mitsubishi FX units with Medoc long before G X Developer became available. I also did a bit on Schneider using Zelio software. All very much simple stuff using ladder logic and internal relays But I've got me a Panasonic PLC that is surplus to requirements where I work and I would like to investigate the possibility of using it for practice purposes. Who knows, I might even get it to do something useful. I expect it is a few years old - its got a version No 2.4 and what seems like a date on it 080916. First query - is there software available for this item. Second query will it be compatible with a computer running on Windows 7. I've checked on the internet and see that there is documentation out there the plc. I decided ask for some informed opinion from before I go too far into what turns out to be a "cul de sac". Regards jaymac.

The FX3U Programming manual is a 995 page secured pdf. You cannot copy-paste from a secured pdf. I reprinted the manual with Soda Pdf and OCR'ed it with Acrobat, using no downsampling. So now i have an unsecured searchable pdf. https://www.dropbox.com/s/3ad2ceclphla0z0/FX3U%20Programming%20Manual%20OCR.pdf?dl=0 Cross-platform and free software used: Pdf Split and Merge Basic and Soda PDF: Combine pdf pages Dassault Draftsight: edit and print autocad dwg and dxf, with 3D and scripting support CloneZilla Live: Create and restore a server/ computer image

Hello, I'm trying to convert time into seconds using the SECOND function. I use Word(signed) array 0..2 but get an error message saying "wrong input data type". What data type do I need? Thank you, Jurgen

Hello all, I am trying to download a new program to a AB 1746-BAS SLC 500 BASIC board via RS-232 connection through a Windows 98 laptop running Hyperterminal. While the BASIC board is connected I verify connection by waiting for the board to print out its information in the Hyperterminal program and then enter "CLEAR", "NEW" and finally, "LIST" in Hyperterminal to wipe any program from the board and verify the board is clean respectively. Then I load the new program via a .TXT file using the "Send Text File" option within the Hyperterminal program. After the program has finished loading I than type "LIST" to verify it has copied over correctly. I than switch the SLC over to "Program Mode" via the key. After doing so I type "RAM" to select the program i just uploaded to the BASIC board and then type "PROG" in the Hyperterminal program. I than receive the "Programming Sequence Failure". If anyone has any advice as to what I am doing wrong it would be greatly appreciated. Below is a list of everything I have set and researched. Thank you in advance, James -Laptop: Windows 98, Hyperterminal -BASIC board (programming): JW1 pin: 1-2 3-4 JW2 pin: 1-2 3-4 JW3 pin: 1-3 2-4 JW4 pin: 5-6 3-4 -RS-232 9-pin connector: Pin 2 connected to Tx Pin 3 connected to RX Pin 5 connected to ground Pins (4/6) crossed DSR/DTR Pins (7/8) crossed RTS/CTS -Hypterminal: Direct Com1 bits per second: 1200 parity: none stop bits: 1 Flow control: Xon/Xoff Settings/properties: -> Emulation VT100 -> ASCII line/character delay: 30 milliseconds check box: Append line check box: Wrap lines... -Manuals: 1746-rm001 1746-pm001
