      AI Bots or a Attack that past 2-3 days

      By Parky · Posted

      Cloudflare seems to be the one to go for, however, a week or so ago cloudflare had a problem for over a day, no details so no idea if it was down for maintenance or it'self had been subject to an attack, it now uses AI. funny really, AI to block AI lol. I know in the past it has caused problems where due to some problem or settings cloudflare was stopping acess to sites for some people but that seems pretty rare now. There is a basic free version that has CDN & DDos plus some others, how long it will be free is anybodys guess

      Help with Error Code

      By Parky · Posted

      That message usually refers to either a PLC Parameter error (in the case of FX plc's) probably ram memory size, or perhaps a register or instruction not supported with that plc. Try downloading only the code & not plc parameters or read the plc parameters into your file so you have the basic as supplied configuration. Other things can be certain instructions not supported in that plc like interrupts for example FX2n through to FX3U have both input interrupts & timer interrupts, but the FX0,1,1N only have input interrupts. Ese mensaje generalmente se refiere a un error de parámetro del PLC (en el caso de FX plc), probablemente al tamaño de la memoria RAM, o quizás a un registro o instrucción que no es compatible con ese plc. Intente descargar solo el código y no los parámetros del plc o lea los parámetros del plc en su archivo para tener la configuración básica proporcionada. Otras cosas pueden ser ciertas instrucciones que no son compatibles con ese plc, como interrupciones, por ejemplo, desde FX2n hasta FX3U, que tienen interrupciones de entrada e interrupciones de temporizador, pero el FX0,1,1N solo tiene interrupciones de entrada.

      Cross gantry configuration and setup (Rexroth IndraDrive to GX Works 3 iQ-R)

      By zeed149 · Posted

      Hi. I want to do configuration setup and programming for Rexroth IndraDrive servo using GX Works 3. I know that Rexroth IndraDrive have its AOIs for Allen-Bradley's PLC. Is it possible that I do function block similarly to AB's AOIs, or is there any function block programming that I can refer or download for Mitsubishi PLC?

      AI Bots or a Attack that past 2-3 days

      By Chris Elston · Posted

      Sorry about the last two days - took awhile to understand what was happening. Had to get my host to help out in what appeared to be an attack from AI BOTS scraping MrPLC.com for data. There was 616,000 requests yesterday alone from AI bots. That's insane and just a new problem that I never knew about. So unfortunately, you might not see anymore results from ChatGTP as a MrPLC.com reference or answer until I understand how to make AI play nice with MrPLC's data. Of course GOOGLE results are still indexed.  have to research how to use Cloudflare to manage AI bot visits to the website. If anyone has ever done that let me know! Crazy..

      Transfering programs from Old Omron NS5-SQ00B-V1 HMI to the new Omron NS5-SQ00B-V1 HMI

      By Crossbow · Posted

      It appears you already have the program.  When you look at the menus, PT is PROGRAMMABLE TERMINAL.  That's the screen.  So transfer FROM is uploading from the connected screen.  To write to a terminal, select Transfer TO.

      QJ71C24N Reception and Framing Error

      By Parky · Posted

      Framing error means you are not using the same parameters like Baud, stop bits, parity etc. you need to ensure that both the barcode & QJ71 are exactly the same
