  1. Beckhoff CP7702-1422-0040

    Hi, In our  filling machine:  the designer installed Beckhoff CP7702-1422-0040 This CP contains a digital  I/O modules  inside it at the back side . Do any member have any docunent or manual that explains how to program the Buttons and the lamps in the front side? Waiting your replies. Thank you in advance.  
  2. Hello! I am working on a quote for a new project that will use EtherCAT but also requires DeviceNet for some legacy components.  Has anyone successfully used the Beckhoff EtherCAT coupler (EK1100) with the DeviceNet Master Terminal (EL6752) and an Omron PLC as the EtherCAT master? My concern is that the coupler will only communicate with the Beckhoff EtherCAT master, but since it is so much more expensive to get the new Omron parts to communicate DeviceNET i am hoping this could be an option.  The equipment is extremely simple and price is a major consideration.   Thank you!!!
  3. Hi, I have a problem with Omron PLC and Beckhoff IO. The IO just disconnects in a few minutes and comes back! I received different errors: Link off error, Illegal slave disconnection, process data reception timeout. When I also check "Display Diagnosis/Statistics information" I see errors on all ports A and B of all nodes.  I have called and talked to both Beckhoff and Omron.  I have two NX1 and one NJ101 to test. And I have three EP2318-0001. I have the same problem with all the PLCs and EP boxes. It does not matter if I have one, two, or three nodes. I have tried different revisions of the EP2xxx from the XML file, different settings for the slave, different task periods, and the error still is persisting.
  4. NEED HELP, TwinCat 3 NCI SlaveAxis

    i am trying to set up dual motors   "master and slave"  on a X axis in TwinCat NCI ,   so far i don some test with "MC_GearIn"   but i keep getting this error       "Error    40    14-05-2016 11:27:39 417 ms | 'TCNC' (500): NC-Ctrl (R0), Cannot configurate axis 4 into group 4 because a slave is coupled or this axis is a slave itself (CoupleState: 1) !!"                when i activate NCI. also i did try using a virtual axis as X and link two slave , but i get the same result :(   anybody knows how to do this ?  
  5. Hello friends, I am an Omron PLC user, but have never used modbus before. I have to connect an Omron CP1L-m to Beckhoff bk7300 via modbus serial gateway. 2-wire RS-485 connection (CP1W-CIF11). I have seen an easy to use Modbus RTU master for CP1L CP1H CJ1 CJ2 CS1 but the examples are not for dual port CP1L-m. If I change the PLC model "CP1HCP1LModbusDualPort" to "CP1L-M", the compiler tells me a lot of warnings about variable types. Is Modbus RTU Master easy to use for CP1L CP1H CJ1 CJ2 CS1 compatible with CP1L-M dual port (port 2)? I have tried to use it but it didn't work, error 02, illegal function code. Somebody could help me? Thank you Enric
  6. CX-8190-Modbus Srv

    Hey guys, I am trying to communicate between a Beckhoff CX-8190 & a third party fieldbus module that supports Modbus TCP, now I am able to write/read to the fieldbus when twincat is running on the local machine (laptop), but when ever I connect to the device and run the same function block it doesn't write nor read to the fieldbus. I am assuming that the modbus server has something to do with it, so is there a way I can install it to the plc ?
  7. ProfiSafe Using TwinSAFE

    Has anyone implemented ProfiSafe over TwinSAFE? Would you recommend it? What obstacles or quirks did you need to resolve? Would you do it again?
  8. Hi all, New to the forum. I've been pretty much able to do the things I wanted with Beckhoff, but now I'm finally running into a problem I can't seem to solve alone. I'm trying to set-up Modbus RTU RS485 communication in Twincat3, using an EL6021. I've implemented a sample program from the Beckhoff website, but can't get it to work. I've got the feeling I need to properly set up the EL6021 but most information on the Beckhoff website is about the KL-series IO. Does anybody have experience with this? The strange thing is that, when I enable the function to read some slave's registers, BUSY is set and remains set. No timeout is triggered. I don't have a slave connected yet but I would at least expect to see something on the output of the terminal, and then a timeout. I've bridged TxD+ and RxD+, and TxD- and RxD- and set 8000:06 of the EL6021 TRUE, half duplex mode enabled). A scope connected to TxD+ and TxD- shows nothing. Code added below. I've added a GVL called 'Variable_Configuration' with the following: VAR_CONFIG     Main.MB.InData AT %IB0 : MB_KL6inData5B;     Main.MB.OutData AT %QB0 : MB_KL6outData5B; END_VAR And then the MAIN: PROGRAM MAIN VAR     bIoSyncMaster AT %I* : BOOL;     MB : ModbusRTUmaster_KL6x5B;     MBLedDriver : ARRAY[1..10] OF WORD;     tmpExecute : BOOL;     bError : BOOL;     bBusy : BOOL;     iErrorId: MODBUS_ERRORS;     iNoDatByteRead: UINT;     count: INT;     freebyte: INT;     TxError: INT;     TxBlocked: BOOL; END_VAR MB(     UnitID:= 41,     Quantity:= 4,     MBAddr:= 16#0020,     cbLength:= SIZEOF(MBLedDriver),     pMemoryAddr:= ADR(MBLedDriver),     Execute:= tmpExecute,     Timeout:= T#5S ,     BUSY=> bBusy,     Error=> bError,     ErrorId=> iErrorId,     cbRead=> iNoDatByteRead);      MB.ReadRegs(); count := MB.MBMaster.com.Buffer.Tx.count; freebyte := MB.MBMaster.com.Buffer.Tx.FreeByte; TxError := MB.MBMaster.com.Buffer.Tx.Error; TxBlocked := MB.MBMaster.com.Buffer.Tx.Blocked; tmpExecute:=FALSE;    
  9. RS485 with CX7080

    Hello i'm newbie. I have a problem with RS485 on CX7080. Busy always True and data=0. I don't know the reason. Please help me! Thank you!
  10. I am trying to create a simple `Hello World` Modbus TCP/IP program using Twincat3 and virtual PLC (PLC running locally on my computer).   I have set up a LabVIEW Modbus TCP/IP master + slave program (both of which are working see screenshots below).  I can send data between LabVIEW's master and slave programs. And also read the data from Python script (so I know for sure they are all working).  Now I have tried to create a Twincat3 program to set some registers using Beckhoff example What I have tried:  - I have tried changing the ipAddr parameter to: 'localhost', '192.168.88.1', '192.168.88.126'  - Also I have tried the nUnitID set to: 0, 1, 16#FF (16#FF as specified by Beckhoff docs) This is my Beckhoff code:     PROGRAM MAIN     VAR         ipAddr         : STRING(15) := '192.168.88.1'; //Tried also 192.168.88.126 and 192.168.88.1 'localhost'         M0 AT %MB0     : ARRAY [0..3] OF WORD;         nValue         : ARRAY [0..3] OF WORD;         fbWriteRegs : FB_MBWriteRegs;         bWriteRegs     : BOOL;     END_VAR           IF NOT bWriteRegs THEN         nValue[0]                := nValue[0]+1;         nValue[1]                := nValue[1]+1;         nValue[2]                := nValue[2]+1;         nValue[3]                := nValue[3]+1;                  bWriteRegs                 := TRUE;                  fbWriteRegs.sIPAddr     := ipAddr;         fbWriteRegs.nTCPPort     := 502;         fbWriteRegs.nUnitID        := 16#FF;             //Tried setting this to 0,1 and it also and didnt work ...         fbWriteRegs.nQuantity     := 4;         fbWriteRegs.nMBAddr     := 16#3000;         //Tried: 16#3000, 0, 1         fbWriteRegs.cbLength     := SIZEOF(nValue);         fbWriteRegs.pSrcAddr     := ADR(nValue);         fbWriteRegs.tTimeout     := T#5S;         fbWriteRegs                (bExecute:=TRUE);     ELSE                  IF NOT fbWriteRegs.bBUSY THEN             bWriteRegs             :=FALSE;             fbWriteRegs            (bExecute:=FALSE);         END_IF                  fbWriteRegs                (bExecute:=FALSE);     END_IF  What should I change in my code in order to make this example work? Thank you in advance for any support!   Info about LabVIEW programs:  I am using the Modbus TCP Master / Slave examples  The IP address is set to localhost and the port to 502 (which should match the IP address in my Beckhoff code)  I am 100% sure it works because I have also tried connecting to this program via Python script.

  14. Dear All, I had encounter a problem when i try to open the plc project from Beckhoff CX9020 plc using Twincat 2. There error show that the File'source.dat' could not be read. I had connected the plc from system manager and i able to load the configuration of plc but not the program.  I do also tried to file the program file from the flash card but i cant find any .pro file. Is that any possible to read the program or source code inside?  Thanks.  
  15. Weird Timer Behaviour

    Hello, I've been using a Beckhoff PLC and TwinCAT3 lately and I'm learning how it all works. Currently I'm using a ton timer in my program and I've noticed some weird behaviour. The timer.IN is set to true and afterwards I check for timer.Q in an IF statement. That statement should therefore only be true after the timer.PT delay value. However, the first time after I activate the configuration and timer.IN is set to true, timer.Q is immediately set to true for a very short amount of time. When I reset all values and try again without reactivating the configuration, this doesn't happen. I'm thinking that I don't initialse the timer in the correct way or something along those line. I have attached a code snippet. The problem I'm encountering is that the first time after I have activated the configuration and the tonTimeout.In is true. The following IF statement is also true without having run for the delay time. This sends my program to an error state. However, after resetting the values this doesnt happen anymore. Can anyone help me with this matter?

  17. Hello. I am working on a pilot project building an automated RV park. Our goal is to have people sign in online, or in person at a kiosk. Make their reservation, payment, and get their confirmation e-mail. In that e-mail, will be a QR, or Bar Code, that when scanned at the gate opens the gate, and starts a light that flashes at the site they rented. Power will then be turned on at that site, and a timer in the process will begin, based off their rental time. Once their time has expired, the power at the site will be turned off, controlled by a PLC, and relays.  So I am looking for help in all directions. I have some leads on some plug-ins for Wordpress that offer reservations, and other plug-ins that do Bar code production. As far as the web part I have that covered. We can generate a custom barcode, or QR code based on individual rentals and those can be sent to customers. So what I need is someone to help point me in the right direction of equipment that can speak between the online Barcode process and the PLC to allow a process to begin when scanned. Based off their rental parameters their power is turned on or off. Perhaps a SQL query in some form? I haven't used it, but am aware of its capabilities, and this does seem like an application where it would be used. Is there anything that you have used that are tried and true? I know it's a strange request, just hoping someone bites. Thanks in advance for any ideas, I look forward to solving this puzzle, one piece at a time. 
  18. Beckhoff PLC + software selection

    Hi, I need to select a Beckhoff system that basically must have PLC with motion capabilities for drives via EtherCAT. The purpose is to test the compatibility of Mitsubishi Electric EtherCAT type drives with Beckhoff PLC. As Beckhoff is a PC based solution and there are many options I'm honestly confused on how to proceed to select a Beckhoff system. Does anyone have experience with selecting Beckhoff PLC that could help with the way to select it? Thanks! Thiago
  19. Dose anyone have experience with Beckhoff FC3121 profibus master PCIe card connected to Siemens CP342-5 as a profibus slave? The data retrieved from S7 PLC is wrong, and keeps fluctuating rapidly. TwinCAT (TC) config looks OK, and it reports that the slave is OK and has no error. The slave is in Run mode with green LEDs. S7 side is believed to be OK as another master from HMS-Anybus retrieved the data correctly. Tried several versions of TC up to the latest (at the moment) ver. 2.11.2305. Here is a zip file with two graph pics of the two masters showing how the "same" data looks like in each case: https://drive.google.com/file/d/1ijlx6AXA3FX8GqgJjwWlFMxPxqT4xN9F/view?usp=sharing Thanks, Hos

Ethercat connection is From PLC to EL6695 module(This module is connected to KUKA robot for mater to master communication) and from Out port of EL6695 to In port of Baumer Encoder. It is not getting scanned nor manually appended. But when i connect it directly to PLC it works fine(gets scanned). Any solution?
  23. Hi i have Beckhoff (CX5020-0120-M310) (profibus master) with TC3.1 and want communicate with Siemens Profibus ET 200S (IM151) DPV1. All modules works on ET200s except 1SI RS232 (6ES7138-4DF01-0AB0). When i triggered Barcode scaner i have one bit ON on no more data from 1SI module. on Array (0..15) of words 0.#0000000000000000 1.#0000000000000001 <= this bit is ON after trigered pushbutton on scaner 2.#0000000000000000 3.#0000000000000000 ..#0000000000000000 ..#0000000000000000 15#0000000000000000 This Same ET200S with this same configuration i have tested with Siemens S7-300 and it works, i can read data from Barcode scanner on the 0..31 array of byte (no WORD's like on CX5020) Siemens have On Communication => ET200s serial interface => Function block S_RCV i use them and i can communicate with 1SI RS232 via this block. But Twincat 3,1 don't have this block. On ET200s i have: 1. 1SI(rs232) module (rs232 parameter is : Data - 8bit, Stop - 1 bit, Parity - NONE, Data Flow - NONE, Interface type RS232-C ) 2 DO modul 3 RTD modul 4. DI 5. RO modul Any ideas where are problem? why can't read data from 1SI RS232?
