Hello guys! A would like to set up a new inverter for my existing machine. I wanna follow the recomandation about the safety wiring. The only problem is I need one more, Z safety output. I checked, there is official expansion unit, and it says I have to only connect the EA, EB, EG, and EP terminals ? Do I have to connect again the X0, COM0 ; X1, COM1 terminals, because I want actually the same inputs, just I need one more safety relay output. I attached picture about it, thanks ahead. 

Hello fellow tinkerers, Inside our company we're expanding our IoT network with the replacement of CJ1G-H to CJ2M CPU units. When swapping models we are downloading the Datamemories back into the CPU. Our engineer warned us to not download all the DM memories: only up to D20000, so I did. When starting we had some inputs that weren't showing in the Data trace: and noticed that it were pulses shorter than 8ms. We found out the "Unit settings" were back to default and this is not unusual since we only downloaded range D0-D20000 but I'd like to avoid this in the future and look up what each datamemory means. I know D30000 to D31599 are the memories for the CPU bus unit settings (manual W473 section 4-5) but what range is the "unit settings" within these 1600 datamemories? I can't seem to find it in any manual I look into (W473, W472).. Also do you see any problems with downloading the full datamemory range?   Kind regards!

hello... i need  help for , how to set up cp1w-cif01 unit in plc for print barcode label. on Omron PLC.

Hi All,  I need some clarification on the PID instruction. The note states that if #9 is set for C+6 04-07, the I & D will be 0.1 to 819.1s. But I didn't understand this highlighted section. Does it mean that my I and D values will something between  (1x τ)~(8191xτ)s??   All help is much appreciated, Stay safe and healthy. T J Sharon

Dear all Please identify me i am having one Issue in my PLC.When I changed the IP of my plc then suddenly its showing error ERH its mean IP address wrong but  My CPU setting is same like previous means unit no=0, x16^0=0 ,Node=x16^0=1  and IP is 192.168.0.15 Mask add.255.255.255.0. but when I, transfer to PLC (in Program Mode) its not transferred(Failed to Transfer) please rectify me where I am doing wrong.

FR-DU04 (FR-A500) vs FR-DU04-1 (FR-V500). Programming unit differences. (A VSD question) What is the difference between these units? Why are they not interchangeable. (Other than the fact that the FR-DU04-1 is used for vector VSD applications, and the FR-DU04 is intended for standard induction motor applications. Is this a matter of firmware differences?

Ring main unit switching devices have three position designs - closing- opening and earthing.. anyone know more about earthing ?

Good morning, I'm having an odd issue with CX Programmer and have hit a wall. I'm trying to upload a previous version of a program to an existing PLC (CS1G-H CPU42) and I keep getting the following error when I compile while online: "The read protection properties which are not supported by the connecting target PLC are set. Check the unit version of the PLC." This prevents the program from being uploaded. I have a first revision CS1, manufacture in 2005 from what I can tell. This exact program has been uploaded previously, but a modified version replaced it recently and I need to go back to the older version. Things I have tried so far. without success: - Removed UM Protection - Made sure Task protection is off for all tasks - Check DIP Switch #1, which is write protection, and made sure it is off - Used "Remove Password" and "Release access" functions from the PLC/Protection menu - Used the auto-verification to confirm the configured PLC is correct - Reuploaded a full backup of H & D memory, from the older program I am able to compile the program when offline, but it chokes when online. I am connecting to the PLC via a serial cable. I haven't found any help from the CX Programmer help, or the CS1 programming and operation manual. This error message is nowhere to be found. Anyone has a clue ? I'm at a loss right now. Thank you !
