  1. port 502 error

    Hi  i am trying to connect to omron plc (cj2m ) from my pc  using modbus tcp/ip in c# , by using the port 502 i  get an error saying that the port can't be reached is there any method to fix that or change the port number ?   thank you 
  2. Hello, I am new to the connected components workbench software. I am working with an AB panelview component Hmi and would like to create numeric buttons to load integers into user variables in a schnieder LMD servo motor. The motor uses Modbus TCP to communicate. It appears that if I click on the numeric buttons properties there is a "Write Tag" of which you can use some default tags or create a new one. I am assuming that I need to create a new one with the motor's addressing but I'm not quite sure how to accomplish this. Any help would be much appreciated!!! Thanks, Steve   
  3. Converting DI to Ascii code

    Dear experts, i'm in learning curve to understanding converting DI to Ascii code. i'm attach here my solution that i'm think should be no problem. may i'm know how to send special symbol plc to printer. communication using modbus TCP. Printer format was: JDU |HEAD1|HEAD2|HEAD3|HEAD4| <CR>  
  4. FX3U-ENET and Modbus

    Hi There i have heard from our local mitsubishi dealer, that there is a Fx3U-ENET module which also supports Modbus TCP. so i ordered one, because i am planning to do a Project using a atv71 FU and a Codesys PLC, so the plan is, that these 3 Devices are able to communicate together over Modbus. has anyone done something similar before? what do i need to setup in FX-Configurator EN, and how can i send modbus commands through that module. i am using GX-Works 2 and have a Structured project. any help would be appreciated. thank you jason
  5. hai, im newbie in PLC, anyone can help me to connect PLC LS, expansion XBL c41a to servo L7S through modbus protocol? thanx and best regard
  6. How To Implement Modbus TCP Protocol Using VBA with Excel We will use Visual Basic for Applications (VBA) to communicate to a PLC using Modbus TCP protocol. Reading ten registers in the PLC and displaying a bar graph in Excel. Previously we have used VB6 to communicate Modbus TCP. The following steps will be done:1.Explain Modbus TCP protocol2.Install OstroSoft Winsock Component– Winsock API Calls for communication on network3.Develop the Excel and VBA application (Microsoft Excel 2010)4.Communicate to the PLC and sample code (Do-More Simulator)Read the rest of the post... How To Implement Modbus TCP Protocol Using VBA with Excel Here is a blog post that I thought was good to share. Let me know what you think. Garry http://www.accautomation.ca
  7. Hi, i am start a aplication whith modbus for a simple comunication(read/write), some analogic imputs and outputs, whith, AB Micrologix 1500 LSP (1 com port Rs232) and whith a Omron PLC CP1L-L + CIF01 (rs232). I using CP1L like a master, but i try a lot of time and no read/ Write happens, just the recognition of Node (1) and the error code 88, no mather whith Function code i use. I use Modscan32 whith Micrologix 1500 and works fine, com settings are right to, i try 38k, 19,2k, and now 9,2k None stop bit 1, setting on CP1L are in serial Gateway. If i take the cable the reponse memory go to zero, so the communication is happen, just dont in right way. Is possible to use, RS232 whith CP1L, for Modbus communication right ? I already see PCMR code for modbus, but is to complex, for my aplication. No ofense. Someone can help me?
  8. Hi. My goal is to communicate from a Wago 750-881 Controller to CJ2M With ETN21 on Modbus UDP. I can only find Modbus TCP function Blocks but would prefer UDP. Does it excist ? Cheers. WagoGrim
  9. Hello everyone, I'm having some trouble to setup the GSM configuration so I can receive alarms on my cell phone I'm using Schneider CPU Modicon M340 in association with a communication RTU NOR0200H and a Schneider Modem SR02 MOD02 this is the first time that I work on this kind of project, would you please help me I'm kind of blocked and I need a solution asap thank you for your time
  10. Serie L and Modbus TCP

    Hi, We have to use a modbus tcp in orden to configurate several festo motor controllers via modbus tcp, We are going to use an L02P CPU because mitsubishi says modbus tcp protocol is implemented in its ethernet port. With FX3u we can use the function ADPRW, Is there any special function in serie L por modbus tpc? thanks in advance. pd: Any experience with MODBUS TCP with a GOT14?
  11. Good day I have a scenario where I need to connect to Ethernet ST-lite units to an L-series PLC. With a Q-series you will use the Modbus card and create a Intellgent Function Module to do this and specify the header addressing for the unit. With the L-series, you have Modbus on the build-in Ethernet port, but how do I now setup and specify the addressing for the for the ST-lite unit? Please help...
  12. On Ethernet/Modbus-TCP, if a device is a Master, can it get polled by another Master? i.e. Can it act as a slave as well. Thanks, Arun
  13. Is possible to comunicate an Eaton/Cutler Hammer INCOM/IMPACC network with a Modbus network ? Any experience ? Many thanks in advance.
  14. http://accautomation.ca/now-you-can-have-robust-data-logging-for-free-part-1/ YouTube overview: https://www.youtube.com/watch?v=6Xa2HYVOxE0 Robust PLC Data LoggerWith traditional loggers, software will read the memory of the PLC and store in a local computer. If the network stops or the PLC communication fails then the logging will stop.Creating a robust PLC data logger allows the communication to be stopped for a period of time without losing any of the data for collection. This is accomplished by storing the data locally on the PLC until communication is restored. All of the data is then read without loss. The amount of time that the connection can be lost will be dependent on the memory size of the PLC and the frequency of the data collected.This series will walk you through the steps to create and implement a robust PLC data logger using the following equipment and hardware.

    There are two Proficy ME projects in the zip file one for VersaMax and one setup for 90-30 CPU364 but is the same for all of the 90-30 processors, but read the Manual GFK-2220 to get the correct port information for your CPU and configuration. They are both working and well documented. They were done quite a while ago but I do not recall what version of PME is needed to open them. It is my recommendation that we all use the latest version. Good luck and have fun with it. R~ <))>(

  18. Hi everyone, I'm facing problems implementing the Easy modbus-rtu master solution kindly provided by PMCR. i'm working with a CJ2M, and i have a SCU41-v1 connected to 5 AC10 series Parker drives, using modbus at Port 1 (Protocol Macro as indicated in the manual- 2 wire). Everything works ok after powering up the system. Unfortunately, after a few minutes, one of the parker drives freezes communication. An hour later....another. And so on. If I reboot the drive, powering it off and on, it starts communicating again. Any ideas about what might be causing this? Thanx.
  19. Hi everyone, I want to connect Allen Bradley 1756-L63 cpu (slave) via RS-232 port to ABB CI-853 (I don't have Prosoft MVI-56-MCM that can easily solve my situation). The only way that I found is application ModbusSlave.ACD (cig-ap129_-en-p.pdf). Do I need AIC+ converter (1761-NET-AIC) or can I connect with cable (DB9-to-RJ45)? Is there another way to make this connection? Regards, Luka
  20. Im trying to control a baldor VFD trough modbus RTU with cp1h/cp1wcif12 using the solution posted here which for me works really fine but the problem comes when I turn on the motor (500hp 440v), the cable gets induced and adds noise to the communication causing errors when reading. I already try to use shielded cable and it gets better but still causing errors. In the solution posted in the link above shows how to connect the cp1w-cif12 by connecting only SDA- and SDB+. So my question is, should I connect FG to the VFD rs-485 ground as well to reduce that noise? Any suggestions are welcome
