  1. Beckhoff integration using Raspberry

    gustavovl posted a topic in Other PLCs

    Hello everybody, I'm new to Beckhoff and I couldn't find the solution yet, I hope someone can enlight me. I need to integrate two distinct and already functional systems: one is working with a Raspberry connected to other devices; the other one is a Bechoff unit getting sensors data. Now I need to get these data captured by the Beckhoff and send them to the Raspberry. Does someone know if I can access these sensors data in a Beckhoffs unit (it's a CX9020, but we can use a EK1100 as well...) by the Raspberry without using any other intermediate device (just the board and the unit)? Thank you!
  2. hey!  I'm pretty new to PLC's, and I'm supposed to ''teach'' the people at my internship how this PLC works, but I have encountered a problem.  I've gotten pretty far with all the digital programming and understanding how everything works, but I just can't figure out how the analog inputs/outputs and programming works...... I've had a fair explaination on PID and how this works. I've searched the web as well to figure out what PLC instructions to use.    I hope you can answer my following questions.    1, what are the most used PLC instruction blocks which I can use for temperature control, and how am I supposed to use them? 2, Could you please give me an example on how to use PID and what numbers will I need for the calculations? 3, what are the most used PLC Instruction blocks (apart form the analog ones) that I should include in my tutorial?   this is my setup: Ethernet switch MOXA EDS-205 Plc voeding PA202 PLC CPU CJ1MCPU11-ETN Digital IN (16x) CJ1W-ID211 (SL) Digital IN (16x) CJ1W-ID211 (SL) Analog IN (8x) CJ1W-AD081 (SL) Analog IN (8x) CJ1W-AD081 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) TRANS OUT (16x) CJ1W-OD212 (SL) Analog OUT (4x) CJ1W-DA041 (SL)   thank you soo much for looking at my question and considering helping me! the OMRON helpdesk hasn't been very helpfull.    kind regards,    Deuslupos,
  3.  hello there ! all the variables are reals ... can anyone explain why i get a different result when i calculate c2 first ??? the two programs shown in the pictures are exactly the same ... the only difference is the posistion of c1 and c2 . please help me . It's not a logic  attitude in programming ..... Any ideas? Thank you
  4. Hello all, I'm new to Beckhoff and running a PLC with EtherCAT I/O slaves. If one of the slaves is disconnected from the network (power loss or network cable broken) the whole PLC freezes, is there a way of configuring ethercat such that it remains (partially) operational, thus showing me the I/O on the unaffected stations.
  5. I am using a Beckhoff windows based controller, with  TwinCAT modular I/O (EL series). I have several problems: 1) Our HMI frequently loses comm. with the PLC. Beckhoff seems to use their own special networking. 2) The PLC ladder language supported is very rudimentary. For example, I had to create my own function block just to do simple analog scaling. 3) Their documentation is pretty bad -- Web based and very hard to find specific information. I would like to replace the Beckhioff controller with a more standard industrial PLC (like Automation Direct Productivity -- I like the programming language and ease of use.) My question is -- how can I use the existing Twincat I/O with AD, for example Modbus TCP. Is there some sort of gateway available for this purpose?
  6. Hello, I am new to the Beckhoff PLC systems and PROFINET. For one of the applications I am trying to connect ETHERCAT module to the PROFINET Controller which is in turm connected to IO modules. I am using the following modules: ETHERCAT coupler EK1100,EL6631 (Controller), EL6631(Device) --> EL6631(Controller)*,EL1008 (Input module) The connection between EL6631(Device) --> EL6631(Controller)* is via Ethernet cable. I am not able to configure the connection in the above mentioned fashion. Please let me know if this is a valid configuration? Is there any simpler way to achive this. And I am using the TwinCAT3 software on my PC.   Thanksk in advance :)

  10. Hello! I have a PLC S7-1200 (1212C DC/DC/DC) and a few question about programming S7-1200 in TIA Portal v13. 1. I want to make "upload station", because I am not surre whichone project is the last. But, when I start upload data, the error hapens, and the decription of error is: The name of the station "S7-1200 Station_1" is already in use in the project. How and where can I change it? 2. And the last question: I try to connect my S7-1200 and Weintek simualtion. There is all time :"PLC not connected". I have chceck everything: PLC is OK, communication PC-PLC ok (ping ok), windows firewall off, administrator rights ok, configuration made with manuals, (CPU - Siemens S7-1200, IP: 192.168.1.100, port 102, tags import - ok.) I have read the manual many times, and check settings - nothing change. Maybe have someone problems like this, and found a solution?

  11. I am converting a PLC-5-40 processor that also has a SST side car for Profibus Dp communication to BK3100 modules on the equipment. To a Control Logix L-72 processsor using a Molex SST-PB3-CLX card to the Profibus modules. Everything went some what smooth until I got to the SSI transducers in the Profibus. The word arrangement is not coming in the same as with the PLC-5. Is there anybody else that has run into this problem and is there a solution. I have contacted Molex, Balluff and Beckhoff the first 2 got back to me I am still waiting on Beckhoff.
  12. Hi I just given a swanky new laptop at work, which is lovely and everything, but does not have an ethernet port. Unfazed by this, I just got hold of a USB to LAN adapter and got to work. My primary development environment is Beckhoff TwinCAT, and was rather gutted to find there are no real-time ethernet devices on the machine(attached image for reference). I was wondering if there was any adapter that I could use for real-time ethernet device. I am aware of latency issues and this would only be used to test communication and make sure everything talk to each other. Cheers
  13. Hi, We have Beckhoff CPU module CX1020-0113 and two Beckhoff AC servo drives conneted using EL7201 card. I want to run both of the motors simultaneously using TwinCAT 2 PLC Control. Since I want to control the position, so I am using MC_AbsolutePosition function block. The sinusoidal trajectory can be taken as 60*SIN(w*t) /*here t is time. w is angular frequency which is constant*/Below is the snippet from PLC program - Please see below image for System Manager Info - Can somebody tell me how to provide sinusoidal trajectory as position? Please note that both the motors must run simultaneously. - Thanks Ravi
  14. Hi, I am calculating velocity and acceleration from position inside TwinCAT PLC Control V2. All these equations have only one variable which is time. Below is the PLC code- (* We are using the external set point generator functionality *)NewPosition := theta_max*COS(omega*t); (* t is time in second *)NewVelocity := -theta_max*omega*SIN(omega*t);NewAcceleration := -omega*omega*theta_max*COS(omega*t);IF NewVelocity=0 AND NewAcceleration=0 THEN NewDirection := 0; (* stand still *)ELSIF NewVelocity >= 0 THEN NewDirection := 1; (* positive motion *)ELSE NewDirection := -1; (* negative motion *)END_IFt:=t+0.01; (* The task is called at every 10 ms = 0.01sec *)(* feed the dynamic data into the external setpoint generator interface of axis *)MC_ExtSetPointGenFeed( Position := NewPosition, Velocity := NewVelocity, Acceleration := NewAcceleration, Direction := NewDirection, Axis := Joint_2);-------------------------------------------------------------(* Below parameters are defined in Global Variables file *)VAR_GLOBAL CONSTANT theta_max: INT := 60; (* in degree *) omega: REAL := 0.62; (* 2PI/Time Period=10sec *)END_VARThe MATLAB simulation of the above equations gives me following results- But this does not work in real Beckhoff motor. Please suggest.

  15. Beckhoff CX1000 PLC question

    pabeader posted a topic in Other PLCs

    I have a machine with a CX1001-0121 controller in it. I don't have the sourcecode for it. I am able to connect and see and force the outputs. Is there a way to extract the PLC program? Even if it's only contact and coils that would be something.

  16. Panasonic FP-X C30R

    jaymac posted a topic in Other PLCs

    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.

  18. 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

  20. Buy what PLC?

    edvinfors@yahoo.se posted a topic in General Topics - The Lounge

    Hi I want to buy a PLC and additional required stuff, to play with at home. Where do I find cheap PLCs? What software do I need to make this work with a Windows 8 PC? What other physical interface and software is needed/recommended?
  21. Hi, I have a problem with my BC9020 and hope that someone can help me. I managed to set the IP adress of my PLC in the 10.2.5... add a root, run a program and make the PLC working for a while. I then tried another program, a new one... and now that I want to re-read the first program, Twincat System Manager doesn't allow me to enter in the "run mode" and stays in "config mode". It also has lost the IP address I set (10.2.5.....) and came back to the 172.16.22... (manufacturer settings) I cannot determine if the problem is in the PLC Control or In System Manager... This is my method to change the IP *** IP config *** 1) Reset the PLC First I place the end terminal next to the PLC. I set the DIP switches 1,6,7 to ON, power on the PLC and power off. I set the DIP switches 2,6,7 to ON, power on the PLC and power off. I set the DIP switches 1,2,6,7 to ON, power on the PLC and power off. 2) Set my PLC on the same AMS than my own IP (172.16.22...1.1) 3) In System Manager, add a new route 4) change the setting in I/O Configuration -> I/O Device -> Device 2(BX9000) -> clic on BX9000 define "set IP Address" to Manual define " IP Address" to 10.2.5...., the AMS change automatically. Press the configuration button and then Ctrl+F4 (run mode) This method worked but seems not to be the best... If you have any Ideas ? or questions? Thank you in advance Gregi
  22. Hello, Im trying to configure a CANOpen master klemme (EL6751) to communicate with a device (Jetter JXM-IO-E09-G07-K00) in the System Manager, I have several problems, and the communication doesn't work, I explain what i did step by step. First of all the JXM works perfectly with a jetter controller, and i have traced the messages, therefore i could understand that the controller in this case sends constantly RTR request for each object and the JXM replies without any problem. I also tested some SDO commands, and seemed to work This time i need to work with a CX8090 Controller attached to a EL6751, that's why I need to configure this now. - After scanning the devices connected, and having the EL6751 recognized, i attempted to add the CanOpen slave also scanning. The process cannot find any CanOpen Device online. - I add the CanOpen device with "Append Box" and I use the EDS file provided by the supplier and the result is not good. Some SDO read/write failed. So i decide to add the device manually. - I use again the "append Box" option, and configure manually the ID, every TXPDO and RXPDO and Parameters NOTE: My CANopen device send constantly a heartbeat and the values only under request => Trans. Type for every PDO: 253. For this I set manually the inhibit and event times. - I uncheck "Automatic adjust PDO COB Ids" and "Automatic PDO Parameter Download". Also, under advanced configuration i disable the object 0x1000 and 0x1006, since the reply never matched to expected values. After doing all this configurations, and activate them, my CanOpen bus stops responding. the LED Code is - Run Led: blink 2 hz - Err led: ON - The system manager is showing much more errors which i show attached in a file. I also include the sys manager file and the EDS file from the supplier Any hint would be of great help JXM-IO-E09_HCN_V0_4.eds.txt Test02.2.b.tsm.zip
