Hi There are a lot of topics on this forum regarding connecting CX-programmer to PLC using ether cable. Ive read most of them and still cant connect my PC to PLS using ether. I will make a detail post how i tried to connect. Please help me figure out what I do wrong. I am using Omron CJ1M-CPU12 I do not know which ETN it is. Ether it is ETN01 or ETN21. Here is a picture of my module: http://imageshack.us/f/692/img0057vfh.jpg/ Now. First of all. Should I use usual ethernet cable or crossover cable? I dont use switch/router between pc-plc communication. Here is how my I/O table looks like that I send over to PLC. http://img849.imageshack.us/img849/4705/inouttable.png Ip adress 210.210.1.101 mask: 255.255.255.0 The last 3 numbers in the IP adress I choose to give the PLC is 101. Ive checked that the node is set to 101 on the CJ1M correctly . Now my second question is. Do I have to set IP adress on my PC to a static one or can I use an auto generated one? The one it auto generates is: 169.254.179.133 and mask is: 255.255.0.0 (mask is different then the one plc has) If you look at my last picture again where I configure CJ1W-ETN21 mode. Do i have to set any adresses in "IP adress table"? or is my configuration ok? Next comes the option where I set communication settings. I set=> PLC network type: ethernet here is a picture of the settings: http://img577.imageshack.us/img577/690/networksettings.png Do I have to edit anything here like FINS destenation adress: network or node? In the driver uptions I wrote 210.210.1.101 as IP adress. If anyone would like to help me out of this, I would be really glad:)
