  1. GOT2000 <-> Omron CJ PLC

    I have an application where I'm using GOT2000 to read data from the weighing unit using RS232 and I send this value to Omron CJ2M through Ethernet/IP. Some variables from that PLC are connected to the elements of the HMI. The problem is when writing the weight value to the PLC through script or Data Transfer is disabled, the RS232 reading works fine, it's fast, etc. However, when I enable the script which writes data to the PLC, the RS232 slows down by a lot, like it refreshes every 2-3 seconds. If i set the script to execute like every 1-2 seconds, it is working better (still slower compared to when the script is disabled) but I cannot leave it like this, because the weight is used to control some valves, pumps, etc. Enabling script doesn't slow down normal communication with PLC, because I tried to test it by displaying the value of seconds from PLC on the HMI and it refreshes every second. Does anyone have idea why such tiny script causes so many problems with RS232?
  2. I'm trying to exchange some data between two controllers. I've used a manual which describes Tag Datalink communication. Everything works fine on the Bradley side, which means I can read values from Omron without problems. However, on the CJ it isn't working. In the Network Configurator I get error every 10 sec (Tag data ling error, code 03D5) and cannot read any data from AB. When I open Connection Structure Tree I see that the input tagset from AB has 'Broken path (0000000000000)' and Unknown Device right next to IP address. I've tried using EDS from the Rockwell as well as uploading it from AB PLC directly - I don't know if it might be EDS issue. The only thing I noticed that inside CJ2M-EIP21 EDS it says that Ethernet/IP is Class 1 connection, however in the 1769-L35E EDS Ethernet/IP is Class 2 connection. Have anyone ever had such a problem?
  3. Hello fellow tinkerers, Inside our company we're expanding our IoT network with the replacement of CJ1G-H to CJ2M CPU units. When swapping models we are downloading the Datamemories back into the CPU. Our engineer warned us to not download all the DM memories: only up to D20000, so I did. When starting we had some inputs that weren't showing in the Data trace: and noticed that it were pulses shorter than 8ms. We found out the "Unit settings" were back to default and this is not unusual since we only downloaded range D0-D20000 but I'd like to avoid this in the future and look up what each datamemory means. I know D30000 to D31599 are the memories for the CPU bus unit settings (manual W473 section 4-5) but what range is the "unit settings" within these 1600 datamemories? I can't seem to find it in any manual I look into (W473, W472).. Also do you see any problems with downloading the full datamemory range?   Kind regards!
  4. Hi All, I connected the controller CS351 to QJ71C24N Module, RS232 setting with non protocol, and got the reading with reception and framing error. Could some one help on the data seem floating in data memory?    QJ71C24N_Reading Data.mp4
  5. Hi all,I'm completely new to ASCII and trying to figure out where I'm going wrong here.Application: I need to send 2d barcode data to a KGK Jet model CCS3000L Inkjet printer. Only protocol possibility is ASCII. PLC I have is a Micro850, and the only port option for ASCII is the serial port. I modified one end of a 2707-NC11 cable to connect PLC TxD to printer RxD, PLC RxD to Printer TxD, and PLC SG to Printer SG. I jumpered CTS and RTS at the printer connector, and the 2707 cable I'm using doesn't have wires on the Micro850 CTS or RTS pins.Printer company verified that I can just jumper RTS and CTS on their side and not connect their DTR and DSR pins (since I'm not using hardware handshaking). I don't really need any flow control for the application ( I don't think...again, ASCII noob here).Do the CTS and RTS on the PLC side need to be jumpered? Does the DCD pin need to be jumpered or connected to something if I'm not using handshaking?I downloaded the Micro800 ASCII read and write functions and function blocks from Rockwell library, and they seem to be working, except that I keep getting ABL error id "7". This error states, "Cannot complete ASCII send or receive because channel configuration has been shut down using the channel configuration dialog box." I have the serial port enabled and configured to ASCII, no handshaking, baud 9600 same as printer, no parity check, 1 stop bit, character length of 8.Any help in pointing out what I'm doing wrong or things to try would be greatly appreciated!   ASCII_TEST.ccwsln
  6. Send and Recv function

    Hi, I'm trying  to use send and receive function. I have to send 2 words from cpu CJ2M CPU33  to CJ1M CPU13. I use enthernet network.  I saw a strange thing  that if I just use send function  then my data goes to second  plc without  having  a receive function.  Its that right? I didn't  mentioned  wich port because  I'm not sure wich  is. I left for automatic allocation. 
  7. need help with programing a cp1w

    hi i am tryning to make a program that takes 4-20ma signals from a  pressure sensor and converting it to show ML on a hmi screan. im using a CP1L with a CP1W-Ad041. but i cant figurout how to set up the setings in cx programer correctly. any tips?
  8. Atlas Copco Simmulator

    I am developing an application which will communicate with an Atlas-Copco torque controller and will be using Open protocol over Ethernet. I am looking for a simulator that I could use to test my software against while we are waiting for delivery of the actual controller. I was sent an application by the controller sales rep but it turned out to be an application that needs to communicate with a torque controller. Any ideas ?
  9. Hi, I have a CP1L and CP1E Omron PLC, and I try to make communication between my PLCs and my system (raspberry pi with Linux OS) using Node-red and specifically using the OMRON-FINS node ( https://flows.nodered.org/node/node-red-contrib-omron-fins) and more detail ( https://github.com/ptrks/node-omron-fins ). So I’m looking for a module to create an Ethernet port for my PLCs. ( both PLCs have RS232 port) . Can you please guide me to find a compatible RS232 to Ethernet module for my PLCs?  Thank you
  10. Hello, I have noticed that a frequent product here is the I-7561U. I'd like to know your reviews. What are you using it for?
  11. Hi.. I have problem with protocol macro for 4 Ports.     I currently use 2 CJ1W-SCU31 (Total 4 Ports) to read from 40 Power Meters, each port consists of 10 power meters.   The problem is that each port can't read the power meter at the same time.   PLC can read the power meter if only one of the ports is activated.   Can 2 CJ1W-SCU31 (Total 4 Ports) read data from the power meter simultaneously with 4 ports? Thanks...    
  12. Symbol transfer when editing online

    Hi everyone, I am having a problem with a CJ2M-CPU33: when finishing the online edits, it never asks me to store the changed symbols and/or program comments, so they are not updated in the PLC memory and cannot be uploaded later. First time this thing happened to me, I am connecting to dozens of CJ in this factory and it's the first time I've encountered this problems in 16 years.
  13. Need a little help

    I am probably over looking something simple but I am stuck. I need to count how many containers come down a conveyor and display it in Indusoft Web Studio 2020. I am using a CJ2M to count from a sensor doing an binary incremental long word (++L) Using long word as the count will need to go into the thousands. (not 100% if this is the correct way). My problem is after 99 the value sent to indusoft is not a number but letters or signs. I am sure their is a simple solution but I have given my self a headache and need a little guidance please. 
  14. cj2m

    hi i am wrting an essay about my final project , i created a scada for omron plc (CJ2M) in factory . ( i am a computer data student )  the thing is , i can't find a good and an easy  documentation ( not the CJ2M datasheet ) to talk about the CJ2M component (port and stuff like that) any help please ?   
  15. Hello, I've been using Mitsubishi and Omron systems separately (in their own environment), and I am fairly new when it comes to connecting these two brands together(plc and hmi). I've been scouring the net for wiring diagrams for the cable connections and also the parameters to be set for a successful communication between those two components. can anyone point me at the right direction as everything I've tried so far has been a failed attempt of making these two communicate. here are the parts and my current settings if this helps: FX3U-64M FX3U-232-BD NB5Q-TW00B or better yet, is there a proper cable that I need to buy for this to work?
  16. Serial communication with KINCO PLC

    Hello to everyone. Nice to meet you all. I am programming a KINCO PLC model HP043-20DT using ladder on KINCO BUILDER. I need to establish a serial communication with my PC. The PLC has a RS485 port which I adapted it to USB to connect with my PC. The PLC allows, at least, two ways to establish serial communication: MODBUS or free-protocol. I've read the software manual and tried to reproduce the examples it provides using the instruction blocks for MODBUS (MBUSR and MBUSW) and free-protocol (XMT and RCV) communications. However, I could not receive the data on the PLC. I could effectively transmit data with XMT from the PLC to the PC and I could verify through a tool called Access Port. In relation to MODBUS, I am using a simulation tool called Multiway from OMRON, however, I get no response from the PLC. If any of you have some experience with this software or this device, I would like to ask you how could I solve the problem. Thank you for your attention. Kind regards.
  17. Hi,  I have a CP2E PLC (CP2E-N30DRD) with an Analog In/Out board CP1W-MAB221. I can't find a method to setup it correctly (the ERR LED is fixed in ON state). The "W516 (Section10) CP1L-EL_EM ANALOG OPTION Boards" manual says to "set the baud rate of the relative option port at 115200bps in Toolbus mode.", however in CX-Programmer , under "Settings" and "Serial 1" tab there is not such protocol. In w614 (cp2e software manual) and w613 (cp2e hardware manual) I haven't found any other tips. Can you help me please? Thank you.

  20. Hello, everyone I have to query a SICK distance sensor from an L26CPU via the onboard Ethernet interface. I have created a simple protocol which I start with the function block SP_ECPRTCL. Unfortunately it takes at least 25ms until the next telegram is started. The sensor responds within approx. 1.5ms. Does anyone know whether that works faster or is that a limitation when using the predefined protocols? Sensor manual:  OD5000, 8021391 (sick.com)  (Chapter 7.4) I am grateful for all the hints. Thanks and regards Dave SICK_Protocol.tpc Messaufbau_vTest.gxw
  21. I have successfully downloaded the HMI program into NB7W-TW00B, but there is no display on the HMI because the communication indicator which is connected by the RS232 cable doesn't light up.  I have verified the wiring and pinout of the RS232 communication cable. What else can be done to troubleshoot this issue?
  22. I am working on project where I need to program delta PLC to receive ASCII code from scanner. I anyone know how to program it helpls me alot.
  23. Hi there, I am fairly new to programming serial communications, especially with Mitsubishi PLCs. Can someone walk me through in ladder logic how to bring in ASCII to the PLC, store the data in the data registers. Then send the data out to another PC once an 'X' input is satisfied? ASCII code would go like the following: C2,0,1,123,2,ABC,3,456,CR

  25. OMRON CQM1H-CPU21 Serial Connection

    Hello Sir / Ma'am,   How to connect Omron CQM1H-CPU21 (Image Attached) to the software for Configuration. I have tried it many times but I think I am missing something from the wiring side. Above mentioned Controller has a built-in Peripheral Port and an RS232 Port, We don't have that particular cable that connects the Controller to the Software via Peripheral Port. Kindly help me to connect the controller using the RS232 Convertor.   I am using ATC-810 RS232 to USB converter. (Image with all Pin Details attached) Software - Syswin or cx-programmer.
