  5. 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
  6. Program Notes & Comments

    I used to use the Old Dos based MEDOC very many, many, years. I havn,t programmed for years now. We have GX Works 2 at work, and I am practicing programming an FX 3G - 40M to try and keep my hand in. Allthough I can write and read the program ok, the PLC keeps saying that it has no memory for the comments. Apparently the memory has to be set on the PLC. Any advice or information links will be appreciated
  7. 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...

  8. 3g3mx2 rs485 cp1l-el20dr-d

    Hi Everyone: I want to comunicate 4 inverters 3G3MX2 through RS485 (modbus) to a CP1L-EL20DR-D.   I remeber that Omron has several FB to use between some PLCs and Inverters.  I wonder if Omron has developed a specific FB to communicate these models, and if it so, where can I find them. Any of you have knowledge or can provide me these FB?   Thank you for your support.
  9. FX3G-2AD-BD Store Peak Value

    Good day, I'm new to this forum and to mitsubishi PLC but was hoping for some assistance with a programming issue. I have been through the hardware and programming manuals without luck for this issue. Hardware: FX3G-60mt FX3G-2AD-BE Settings: Structured ladder/FBD Current input mode on: M8260 (first board, first input)   What I need to do is to record the peak value over a cylinder stroke period. The hardware manual explains how to average the value using averaging time, however I basically need to peak hold and send that to a D register for go no-go compare.    Process as follows: Contact closed, monitor D8260, contact open, move peak value from D8260 during monitor duration to D205.    Thanks in advance for any assistance. -Swervomotor

    Dear All, I really appreciate in advance your help in this problem. This is my first project with Mitsubishi PLC. I am using GX Works 2 for programming. Hardware is FX2G-24M base unit + FX2n-16EX extension module. I already started a new program and download simple rung on PLC, put PLC in run mode, test it and working properly. the problem is that I do not know what is the address of inputs of extension module. I tried to complete and use X016 but no response in PLC. kindly advise what shall I do. Thanks

  14. 4 cpus cp1e and 1 hmi beijer over rs485

    Hi i want to connect all 4 cpus(cp1e 40s) to the hmi(beijer ixt10a) over rs485. I don't want the cpus to communicate each other, but i need all of them to exchange data with the hmi. How can i do that. Do i have to make master/slaves and from the polled plc to exchange all the data or if i don't set up anything in the plc's i can communicate each one with the hmi if i set the nodes to each plc and the hmi(for four controllers). I mean i will just wire them and set the hmi that there are 4 controllers, i will set node 0,1,2,3 and after set the hmi to these nodes. Is it going to be any problem between the plcs that aren't programmed to communicate each other and will be wired with rs485? Thanks
