  1. Hi,  I'm trying to test the serial communications with my Micro820. I acquired a 2080-SERIALISOL so I could have "someone" to talk to. I want to use RS485, so I figured that I'd have to connect: Modbus pin 1 (D+) to serialisol pin A1 (+485) Modbus pin 2 (D-) to serialisol pin B4 (-485) Modbus pin 3 (GND) to serialisol pin A2 (GND) Now when it comes to CCW, the thing gets a little harder. I know I need to use the MSG_MODBUS block (in fact I need 2, one for the modbus and another one for the serialisol), and I guess I specify the interface I'm using on the TargetCfg field (data type MODBUSTARPARA). But how do I figure out that the Addr (UDINT) and Node (USINT) values are for my Modbus and Serialisol? Or am I doing it wrong? Does anybody know of any place where I can get some more guidance or even a funcional ladder program? Thank you in advance
  2. Mitsubishi communication error

    Dear all,   I have Mitsubishi FX1S Series PLC while i am downloading program , i am not able to do it and i am getting error. please find attached image and please help me to solve it.
  3. Hello,  I am a newbie to the Omron world. We have a new machine come in made on Omron PLC, we are trying to get it connected to our OPC server so that the server can read and write tags via ther Ethernet/IP protocol. We have given out ethernet card IP and the NJ501-1300 controller is on But still our OPC server cannot see the tags/variables. I dunno if we have to add the ethernet communication card to the network configurator and add the tag sets ?  We are also getting a tag resolution error on sysmac studio while being online.    Thanks Pratik

  5. Master/Slave Communication

    Hello guys, I am using Fatek PLC's to communicate with each other as a Master & Slave through zigbee which is connected through RS485. And I succeed. But the issue is that I have to communicate each other at a distance of about 2km where zigbee out of range to each other. I am bit confused here; 1) whether I use RF booster? Does it work? 2) Should I introduce extra PLC as a repeater between master slave? But this(extra added) PLC repeater also become as a master(Master Repeater).or any idea? Most important I can using Fatek Protocol or Modbus RTU or Modbus ASCII prootcol.

  7. S7-300

    Has anyone ever use a Allen Bradley 9300-ENA card with a Siemens S7-300?
  8. Hello, I am currently installing a PLC control panel and due to space constraints, we will need to install the Panelview 600 HMI separate from the Micrologix. We purchased a 50ft Allen Bradley communication cable, but 50ft will not be long enough. We have about 70 to 75ft of conduit between the panel and the HMI. I would like to know what options we have for this connection. I read that for serial connection, we shouldn't go past 50ft. I understand the Micrologix 1100 has an ethernet connection and the Panelview does as well, but I'm not sure what changes would be needed in order to communicate through the ethernet port, instead of the RS-232 port. Any suggestions will be greatly appreciated.   Thanks, JCG

    The topic is based on "How to configure a PCM module in GE PLC". One new query in PCM. To configure this PCM Module some procedure is to be followed in CMD prompt. Initially once ''READY'' line displayed. Query to this topic is if ''READY'' line repeats below persistently in CMD prompt, then solution is ______???? 
  10. Hi again I browse through half a dozen mitsubishi manuals but turn up nothing for mitsubishi plc cross-communication. In this project there are about six L-06 plc:s. All are on the same ethernet network already, communicating nicely with the SCADA system. Per today information is (temporarily) exchanged via the SCADA system. Here is another hole in my knowledge. Namely how to correctly setup communication between these plc:s. I plan to continuosly exchange some 50 bytes of information. I would be grateful for some pointers and/or perhaps a reference to a manual. Cheers to all of you //
  11. PLC won't connect with PC

    Dear sir, My problem is I connected with PLC with cable and uploaded the program and it's working nice, but when I removed my cable and connected the monitor panel it have communication error, I connect my PC again it won't see the PLC, the PLC functions I/O is work but I can't connect with PC or monitor panel.  So if their any reset for communication port or the port is damage?  
  12. Hi All. I have AB PLC Micrologix 1500 and HMI PV600. In factoryTalkView ME I have installed RSLinx Enterprise and I have setup communication setting I have created one shortcut like PLC1 linked it to PLC ML1500 which I can see in right side of setting pan. I copied these settings to Runtime target. Now while giving animation in screen e.g. colour, I am trying to browse tag but it's not showing anything in online folder. I clicked show all server, refreshed all folders and restarted RSLinks Enterprise service also but still can not find tags. I ran runtime on PC using OPC created in RSLinx Classic, Its working fine, I can browse tags. But it's not working while I download it in HMI as I can see in HMI configuration network and comm setting there is only RSLinx Enterprise is available. Please suggest me solution on this issue.
  13. We are communicating FX3GE PLC with Vijeo Citect SCADA. We tried various protocols such as MelsecNET, MelsecFX2N, Melsec1, etc. If you know how please help.
  14. Hi. I'm hoping someone can give me an answer on this problem I'm having with a FX3GE PLC. I am trying to get a FX3GE plc to communicate to a drive over RS485 using a FX3G-485-BD card. In GXworks2. But am having no luck.  I have tried changing the PLC communication settings in PLC parameters between CH1 and CH2, But am unable to get any communication working on the front port. I have also tested with a FX3G-232-BD RS232 card and have the same problems. There is no activity on the SD RD led's and no data being sent. If I put the FX3G-485-BD card in a FX3G or FX3S PLC I have running the same code it works fine. So the problem I'm having is with the FX3GE PLC Please can someone tell me what the difference is with the front Communication port on the FX3G and the FX3GE. And how I can get the FX3G-485-BD card working on the FX3GE PLC. Thanks

  17. Ethernet to PLC program

    How do I read a Mitsubishi PLC program through a QJ71E71 Ethernet card mounted on the same rack?
  18. Here is a post that we recently completed on the Automation Direct USB to RS485 Adapter.  The USB-485M is a 2-wire USB to RS-485 serial communication adapter for RS485 use. It does not require an external power supply or complicated configuration. It has a Type A (plug) USB connector for the computer side and a universal female RJ45/RJ12 modular connector. This will accept RJ12 and RJ45 plugs.  The USB-485M supports multiple baud rates and is USB V2.0 Compliant. Read the rest of the post...

  23. IFIX Scada communication issues

    I am new to ifix, I am having an issue, I am unable to receive any information, after attempting to fix the fact that the view was only pulling half the data I lost it all, I had a back up saved, but it didn't work on restoring communication, I was getting a cannot connect to node error, but I have fixed that, now all I am getting is question marks. essentially I believe that I have two standalone computers with the ifix software and the communicate directly with various plcs that share information across, either a ring topology or full connected. so the computer I have that is working is setup with scada and the database and MB1 with no network support, the one that is not working is set up the same, my cable connection is a usb to Ethernet and im communicating with a Comm port on the computer. I've tried different comm ports, even contacted GE, they were suppose to have someone call me back but no one has yet. Can anyone give me an idea of what I've got wrong here?
  24. I am working on a project with Micrologix 1400 and PanelView C600 I am not able to communicate over Ethernet with any device and my computer. I was not able to load the HMI screens so I don't know if they are communicating between themselves. The RSLinx does not see any device connected via Ethernet. I am using EtherNet/IP driver for this, not sure if that is right. I have tried connecting directly to each device from PC over ethernet and also connecting to them through switch. I can however ping each device and the packets are coming back. The IP assignments are as follows: Router PLC HMI PC Would anyone have any suggestions what I need to try to get this resolved? I was able to communicate with the MicroLogix via serial port but was not able to communicate with the PanelView through serial port at all. I have tried using the USB-2711-NC13 cable for the PanelView connection. Thank you.
