  1. All, I am using Keyence CV-X422A vision controller for my application. It is interfaced with Siemens S7-1500 PLC on PROFINET. I am able to communicate with Vision controller through PLC logic command and status IOs. There is some communication issue in updating the o/p values from Camera Controller. I have tried with & w/o Handshake Mode with these settings. The camera display shows the reject but camera never turns ON the NG Status o/p. I tried different things told by Keyence Tech support but none of them worked.  He told me to have you enable the “Result ACK Flag” in the bit allocation area and send  a signal to it. Then trigger it again with a no good part and see if that fixes the issue. I tried setting the “Result ACK Flag” to 1 after I get the “Command Complete Flag” for the trigger signal that I sent. Sometimes this works but still it is not reliable. Do I need to send only a pulse to “Result ACK Flag”? Anyone here has ever faced similar issue?  Thanks for your help. AP
  2. Trying to change out an old flakey Keyence KV-24R processor with a current KV-24DR.  The Ladder Builder software I need to upload the program form the old PLC has to run on an XP computer.  I was finally able to install a trial version of the software (after waiting a couple weeks for for access to an XP computer from the company IT department). The software ran the first time, but I had to restart my computer.  After restarting my computer, when I try to run the Ladder Builder software, I get "Illegal initialization data" and the software shuts down.  I have reinstalled the software a few times already.  I have left a message for Keyence, but they don't support their own products in America (they are sending my question to Japan.  Anybody have any ideas?   Sean

    This is an example (with code) on how to cycle user messages on the Keyence KV-D20 display. The code is written as a sub-routine that is easily incorporated into a Keyence KV series PLC. The code is proven to work - I've used it many, many times. A brief rung-by-rung commentary explains the basic operation of the code.

  7. Keyence KV-40dt Program Access

    I have a couple older Keyence KV-40dt that I need to modify the program on. The equipment designer is long gone, but I think the program is read protected. This is done using MEMSW $8000. Some of the programs are fairly complicated, so it is potentially worth some effort to get access.   I found this software program to backup the program: http://forums.mrplc.com/index.php?/files/file/647-backup-tool-for-keyence-plc/ It is a demo version that allows downloading the program. However this demo version doesn't allow reloading that program. The company seems defunct and I can't find any valid contact info or a non demo version that allows reloading the program. In another post PLCutils mentions " Any person can read such "pseudo" protected program the same way as Ladder does it with 0x32, 0x00, command." However, I don't know how to write a program to the PLC.  The program downloads a .cod file. In a hex editor it looks all scrambled, but I was going to try to decipher how the MEMSW $8000 gets written and edit the hex. I need to be able to reload the .cod file for this to work. Does anyone have any ideas? I also saw that .cod files are read by the KV Incrediware software for dos. I don't know if this is the same .cod file format that I have, but I may try getting a copy of that.

  10. I need some help and advice communicating between an Omron PLC and a Keyence KV-5500. My system typically uses an Omron CJ2M-CPU34 which comes equipped with the built in Ethernet IP port.  My customer is insisting that we change the CPU in our system to a CJ2H-CPU66-EIP in order to communicate with the Keyence KV-5500.  They have not been able to detail why their communications require the CJ2H, they just say they will be using Ethernet TAG communication and for this they need us to change the CPU. Has anyone successfully established communicated between the Omron PLCs and the Keyence?  If so how did you do it and which CPU did you use?  Is there an .eds file available for the Keyence CPU? Please help!!! They will be visiting from halfway around the globe to test communications in January so I want to be prepared!
  11. I have camera Keyence connected via ethernet to the S7-1200. In the cameras can be set about 30 "tools". Each "tool" perform a different function in the image. In what way in the program code on S7-1200 I can read eg Tool number 10? For example, if tool 10 is the correct I want to to value 1 on some tag for eg camera_tool1. Thank you in advance for any help. Regards Mikołaj
