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

Hey Guys, I am using CJ2M plc and all I want to do is read some parameters from MURR IO-Link connected to Master block. I have all the information required to read the data and I am also able to do that with the network configurator but having hard time doing it with PLC instructions. I have attached the image of how my network configurator file looks like. It has details related to service number, class id, instance id, attribute id and data.    I have tried using EGATR, CMND and EXPLT instructions but have no success reading data from the MURR block. It will be really appreciated if some one can help me find out where I am missing something in PLC to implement any of this instructions.
