¿Es posible usar un PLC Melsec FX5U como maestro (cliente) y esclavo (servidor) TCP simultáneamente? Entiendo que esto es posible con la serie L, pero no sé si con estos. De ser posible, ¿qué se necesitaría? ¿Es esta biblioteca estrictamente necesaria o hay una manera más sencilla de hacerlo? Google translation: -
Hey so I Keep getting "PLC Response error" on the hmi I'm connecting a NB10W-TW01B hmi to a Omron Nx102-9020 Using ethernet 2. Using Sysmac Studio For the plc programming and NB-Designer for the HMI I have tried a bunch of "Fixes" and read the forums I could find but no succuss "Solutions" Tried 1. Changing IPs and Nodes 2. Change Ethernet port (In addition Aswell as separately to 1.) 3. Blank program with only Communcation setup 4. A few other things but nothing has solved Let me know what files or info you need if you would like to help me. Thanks for your time 🙂 -

Hello friends,I have a CJ2 CPU and I want to connect it to an IG5A-VFD LS through a CIF12 card using the Modbus RTU protocol. Is it possible? Can you guide me? Thank you. -
I did it. the problem was in the incrementing counter inside the interrupt task --> I used @++L(591) but i should use just ++L(591). -
Hi All. I have a project to setup Scheduled Interrupt Task in CP1L PLC. I can not make it work. What i did: 1. Set up the Scheduled Interrupt Interval = 10ms in PLC/Settings -> Downloaded to the PLC and Power it OFF/On 2. I create a new task and attach it to Interrupt Task o2 (Interval Timer 0). In this task i have only one increment counter and one SET instruction to see if it even enter in the interrupt. 3. According to the Omron UserManual i execute MSKS(#14,#1) on the startup (P_FirstCycle). I am expecting the Time_Interrupt task to execute every 10ms. And the interrupt never executed. Where is my mistake?

In general, downloading the firmware to a device will wipe out all of its memory. The only restore utility I've heard of is one that Red Lion provided to me when a firmware update failed partway through. It recovered the HMI's firmware, but not any runtime database. I'm afraid you're out of luck. Do you have a way to contact the original programmer or a similar machine that's still functional? -
Ta, for your constructive response. I've specified the inverter in brackets, however it is the OMRON 3G3M1 inverter (VFD). I would appreciate if you could post the URL for the OMRON libraries to which you're referring. To launch a search with no specific location results in a long winded search on the internet. Cheers, keep safe. -

Hi, Just wondering if anyone has inadverantly downloaded new firmware into a working G303 HMI, whilst trying to upload the program? This seems to have wiped the program as the panel display is just blank. Obviously, I don't have the source code which is why I was trying to upload. Some google searches suggest that there is a system restore option in a hidden menue available when booting up. I can't seem to find it. Just hoping someone may be able to point me in the required direction. Or just tell me i've knackered it up! Thanks in advance, Paul -
Did you check if the CPU and RJEN71 are the latest verisons available? https://www.mitsubishielectric.com/fa/download/software/detailsearch.page?mode=software&kisyu=/plcr&shiryoid=1000001294&lang=2&select=0&softid=1&infostatus=6_1_1&viewradio=1&viewstatus=&viewpos= -
This depends on what you want to do. Do you want to disable it permanently? If so, then either delete the rung or make the P_On contact Normally Closed. I would perform a cross reference on StartLog tag. Is there a Reset (R) StartLog output used in the program? Is there an HMI attached? Is StartLog used in the HMI?
