  1. 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.
  2. 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 10.14.9.187 IP and the NJ501-1300 controller is on 192.168.250.1. 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 
  3. L3 Serial Communication

  4. 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.
  5. Hi All, We have an old machine using a Mitsubishi Fxo-30MR/ES and I will be replacing the PLC with a FX3S-30MR/ES.  This old machine would power some led's on a panel mounted PCB using the PLC outputs.  The 24V from the PLC output would go to the PCB board where a resistor would drop the voltage for the LED.   This PCB is damaged I would like to avoid getting a new PCB made and instead power some panel mounted LED rated for 24V directly form the PLC output.  I guess these panel mounted LED have a built-in resistor.  Power consumption for the LEDs are 20mA at 24V volts.  The 24V power supply has plenty of capacity for this. Are there any issues with doing this? I have attached the spec sheet for the panel mounted LED (I will be using the 24V versions).   Panel Mounted LED.pdf
  6. FX3U For GXworks2 and WinCC Flex

    Hi, Is there any way in order to monitor both PLC(GXworks2) and HMI(WinCCFlex) using only 1 port from the PLC(FX3U)? I have tried it but I'm not able to communicate the other application(one at a time only).   Thanks!
  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
  9. GE PLC PCM

    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

  18. Elecrical Control Panel

    Which type of electrical panel is most reliable, give some idea about that ..?
  19. 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...

  20. Hello, I have a remote io cabinet with a rack of Siemens ET200isp. This was chosen because the almost all of the equipment connected to it comes from the hazardous area and is Ex ia. This presents me with a problem because I have two pumps that I need to turn on and off with this rack, and I cannot drive a contactor with intrinsically safe io for 2 reasons: 1. The power output is too low to pull in a contactor 2. There would be no barrier to separate the intrinsically safe wiring from the 'safe area' wiring containing the 3 phase for the motors. Output card is a 4 F-DO Ex 17.4V/40mA (6ES7138-7FD00-0AB0) My original plan was to use a Pepper and Fuchs KFD2-SR2_Ex2.W on the output of the Siemens DO card to provide a safe area dry contact that I can use to power my contactor. This did not work however as the KFD2-SR2 is not designed to be connected to an active current source, so both the IO card and the barrier were trying to power eachother and switching was not possible. I can get it to work if i power a standard 24v relay from the DO card, however this does not solve the problem of properly isolating the hazardous area wiring from the safe area wiring as a relay is not an intrinsically safe barrier. I can put a zener barrier in line with the coil of the relay however this cuts the power down too much and the relay contacts do not reliably pull in. I'm asking if anyone has any ideas, we are beyond the point where installing a new IO rack that is non-ia is an option, it would require a whole new cable run for the profibus. Is there such a thing as a relay that can be powered by the intrinsically safe output? I hope that is enough detail, please feel free to ask if more info is required. Thanks in advance for any suggestions.
