  1. Cannot connect to CJ1M

    hello, indeed I made a "fast" cable and I was not able to connect to the PLC. I used the "auto online" function on CX-programmer. How likely is this to happen? I'm going to try the regular cable and hope for the better :). thanks Carlos
  2. Cannot connect to CJ1M

    thanks for your help! I have one question though. What do you mean by "PLC 1-----------Shield PC"? Pin 1 of the PLC DB9 plug should connect to? thanks again! Carlos
  3. Cannot connect to CJ1M

    Hello, i used to be able to connect to a CJ1-M ETN11 through ethernet using FINS. Everything was going fine but i had to change the network settings. Basically i maintained the ip and changed the subnet mask to 0.0.0.0 so that i could connect to it with another network. Bottom line. I can't connect to it anymore. To program it I used ethernet too. Now i can't do anything. What can i do? I have a serial cable with the following configuration: CJ1M (male pins) PC (female pins) 4 shunted to 5 4 shunted to 6 7 shunted to 9 7 shunted to 8 2----------------------------------2 3----------------------------------3 9----------------------------------5 but i still couldn't find how to connect to it. Any help please? best regards Carlos Cândido
  4. where can I download cx-one ?

    thanks Bertie, i think something like that happened... apparently my local omron representative wasn't fully aware of this so I only got the license... they'll hopefully send me the DVD tomorrow =). thanks once again! Carlos
  5. where can I download cx-one ?

    hello everyone, I recently purchased a license for the CX-one... today I received a package with a license code... I was expecting the code... and a CD or DVD to install the application! How is it processed? Am i supposed to use the key in order to download CX one from the internet? I tried to reach omron here in portugal but there was nobody available who could tell me about it today so i can only wait... can someone tell me how this works?
  6. Understanding the FINS Protocol

    hello everyone! curiously or not, I just received an e-mail from omron showing me this manual and explaining me the WR issue! Many thanks everyone! I'm planning to put the intelligence on the PLC, though, as I still don't have any cx software, i'm still unable to do much in the PLC therefore, to make some simulations and study some applications of what i'm doing, I'm working like this :). once again, many thanks everyone! Carlos
  7. FINS and Visual C++

    hello moosty, thanks for your help! Either way, I was advised to build my own code for this so... here I go :) Once again, thanks! Carlos
  8. Understanding the FINS Protocol

    Hello, I've been recently introduced in a project which consists in a series of CJ1-ETN PLCs which will connect with a computer via ethernet. In order to achieve this, I'll use FINS as it seems quite simple to understand and i've been messing around a bit with a VB program I was given and I couldn't understand the FINS command MEMORY AREA WRITE. This is the command being sent in the VB program I was given (I have no idea where it came from): 80,00,02,01,66,00,01,05,01,00,01,02,31,00,00,01,00,01,01 After sending this command to the PLC it activates or deactivates one of the outputs of a OC201 module. Never mind the commas, I just put them for readibility purposes :P After reading the FINS Commands reference manual, I understood The first set of bytes: 80,00,02,01,66,00,01,05,01,00 which are mainly concerned with the configuration of the communication (nodes, etc.) and also the two bytes that come after these: 01,02 which identify the MEMORY AREA WRITE command. My issue is concerned with the next byte: 31 which is related to the memory area code. After reading the manual I noticed this byte should be 80 (CIO, LR, HR or AR area), 81 (Timer/Counter) or 82 (DM), though in this case, it has 31. I'm still waiting for a version of CX-one to arrive (it has been ordered already) and I can not do much more on the PLC, therefore I'm going a bit blind here. What i would like to know is why number 31 associated with outputs? Shouldn't be associated to 80, 81 or 82? Thanks in advance for your replies! Carlos
  9. FINS and Visual C++

    hi there!, i'm quite new into the PLC world and recently I was given the task of communicating a PC and a PLC via ethernet. After reading here and there, I bumped into FINS protocol, which I dare to say it suits my purposes. I tried the VB programs in the download area and i managed to connect to a PLC and enable outputs and read inputs successfully but I would like to work with C++. Is there any code or software available developed in C++ which allow to communicate a PC with a PLC via UDP/ethernet? Thanks in advance Carlos
