Hi all,  Could someone offer me an example of FINS communications between CJ PLCs using CMND or CMND2?? I have been trying it and I am able to send or write, but I am not receiving the response properly.  Thank you!! https://forums.mrplc.com/index.php?/topic/42788-no-response-cmnd2-fins/

Hi all,  I am trying to modify the date and time of several PLCs from other PLC. Them are all CJ2M, and they are all in the same ethernet network (192.168.100.xx) and in the same FINS network (#1). I am doing it using the FINS command 07 02 ("CLOCK WRITE") with the CMND2 instruction. It is not working entirely: the clock time is being modified at the specified node; however, I do not get the FINS response (expected 07 02 00 00). If I modify the number of retries of the CMND2, the command is repeated all the specified retries though the clock was already written on the first try.  The D+0 and D+1 (response channels) are always #0; nevertheless, the I+1 ("Communication Completion Code" channel) allways receives #205. Acording to the manuals, this code is for "Response Timeout". I have tested it with 10 retries and with 10.0 seconds of monitoring response time, but it is working in the same way: the clock is modified fast enough, but I am not getting the FINS Response and the I+0.00 bit is ON after 100 seconds...  I have been also doing tests with the OMRON's Etherway Software, sending the same FINS command, and here I am getting the response properly. (???) I would say the FINS network was set-up correctly. All the PLC were set in network #1 with Cx-Integrator. In fact, they are currently sharing several channels using the SEND command on this network #1. I don't know what I am not doing right... Any idea?  The ladder is attached as .cxp and as .png. Thanks a lot.  Best regards.  CLOCK_WRITE.cxp

In my system, MT8150XE and Allen bradley compactlogix communicate with PLC ethernet. When I compile the project I made with Easybuilder pro v5.01.04 and upload it to the screen with v6.05.01.565, it does not communicate at all and I get a no response error. only difference between the two projects Previously Driver V.1.50, ALLEN_BRADLEY_EIP_COMPACTLOGIX.e30 In the new one, the Driver says "Device ID: 156, v.1.80, as. ALLEN_BRADLEY_EIP_COMPACTLOGIX.e30" Copying the ALLEN_BRADLEY_EIP_COMPACTLOGIX DLL file from the old version driver folder to the new version folder, it rarely gets online. Is there a solution? Thank you from now

Hi, I've been working on a new software for a Weintek HMI model MT8071ie, which is controlling an Omron CP1E PLC. The computer is currently being used to simulate the HMI, connected to the PLC via USB. The connection between the computer and PLC has been flawless for the past few weeks I've had no trouble at all, but now all of a suden everytime I go to the online simulation I get the PLC No response that pops up. I've tried going through my settings several times to find an error somewhere, but nothing seems out of place. I also tried different cables, different PLC, I tried using backed up versions of my program that worked a few weeks ago with no success.  When I connect to the PLC using CX programmer it works everytime, so it doesn't seem to be a hardware issue. I'm starting to run out of ideas on where to check, if anyone has even a small idea on what my problem could be that would be great.  thank you!

Can Anyone Come Up with the Screen Shots or a video link of procedure for Displaying Real Time Sinusoidal Waveforms From Satec MFM ON GE FANUC?? I have PACsystem RX3i via Serial Communications Module-IC695CMM002 

Hai, I have downloaded the program into the PLC, downloaded the program into the HMI VIA ethernet.When I turn on the HMI it's showing "PLC RESPONSE ERROR". I can write command to plc through HMI, But I can't read the signal from PLC, Does anyone know the meaning of this message or what I might be doing wrong or missing out?...CPU used:CP1L-EM40DT1-D, HMI used :NB7W-TW01B...PLC to HMI communication via ethernet...
