Posted 8 Apr 2016 This is my first post on this forum and need some help from the experts: We are still using V600-H11 RFID reader/writer (old production line). A new production line is being assembled and we had to switch to V680S-HMD63-ETN , I think the V600-H11's are being obsoleted. We bought CJ2M-CPU33's for this new line and I have some questions regarding the compability and/or hardware needed. - Do I need to buy a CJ1W-ETN21 module to connect the RFID or can it be connected directly to the built-in ethernet port in the CPU? - is the ladder diagram similar to the one we are using for the V600's ? or function blocks HAVE to be used ? - Does anybody has a ladder diagram sample for this V680's reader/writer? Thanks in advance for your time to read this message and help. Saludos desde MX Share this post Link to post Share on other sites
Posted 8 Apr 2016 Based on a very quick review of datasheets and manuals, The V680-ETN is a Modbus TCP device. I am not seeing where the CJ2-CPU33 or the CJ1W-ETN21 support Modbus TCP. I think the better option would be the V680-HMD63-EIP unit. This would connect directly to the E/IP port on the CJ2M-CPU33. However, I may have missed something in the documentation.

Posted 9 Apr 2016 gtsuport, You are absolutely correct. gusovi, You can use socket services with a CJ1W-ETN21 to do what you want. I posted some code in the download section, you can find a good starting point here: Share this post Link to post Share on other sites
