Exactly.

Mitsubishi iQr and Mitsubishi Q, support Profinet. Also most PLCs based on Codesys support Profinet,

You can use Inray OPC router. It is free for download and time limited for test.

Obviously you didn't understand me. It is probably due to fact that English is not my mother language, so I didn't explained it well. You can use system bits - obviously. It's their purpose, but some are read only and some are both Read and Write bits. There is one big difference, Read Only bits are controlled by the state of CPU and PLC equipment, so they can't be Latched. Also this is only relevant to PLCs that use those system bits and that is FX0 to FX3 series. In your example there is SM400, so it means that you do not use FX0-FX3, but Q or iQr or iQf.

Nobody should use PLC as PSU. Nobody needs to be that cheap. Infact that old PLC has quite good PSU but it is with very limited power.  Both products are very old. I had quite few Bejier's HMIs failing in last few years in similar manner as you described, and I never had FX1N failed.

You can't use bits over 7999 as they are reserved for special PLC bits. For example L8000 is the same as M8000 and it is "Always On" bit and it is read only.

Drive needs to be configured/programmed according to application. You need MR Configurator2 and USB cable to program/configure drive. If you read PLC and HMI, it's apps will give you indirectly some information , but not all. The drive you have has program and point table capability, so it means that lot of thing need or can be configured. Best thing is to contact original producer and ask them to send you .mrsc2 file for your machine. After you download it to machine it will work, if it is correct one.

Nibbles not bits. K8 = 8 x 4 = 32

Also with GT21 and GS.

Left click on object -> Setting-> Click on most left tab "Trigger" -> Check "Control displaying/hiding" ->  Select the appropriate device that controls visibility and state 

I've opened it successfully. You need to rename the directory to some Latin alphabet name and to copy it on location that's path is not to long.

If you use it in both directions it 4096, if you use it one direction it is 8192. 0 represent 0 degrees and 4096(8192) represent 360 degrees... But you need SSI interface in order to connect to encoder.

It Is "State machine" and it is explained in manual on CD that came with VFD.

Thank you.

I'm interested in FX Toll. Where can I find it.

You should check M8034 bit. It is "All outputs disable bit", and it sets off all external outputs, but I think that LEDs remain on...

You need Edops or Edops2 plus software. Some are dongle protected. Programming is nightmare. If the machine is AEW Delford (Marel) IBS2000 slicer, I can be of help.

Or you can store "factory values" and restore them when you need them (look at %SW96 and %SW97). Additionally you can program digital input as "run/stop". Best regards, Vuckovic Goran.

It is Schneider Electric Twido TWDLCAA40DRF or similar. Programing software is Twido Suite, and cable is TSXCUSB485. Software is free. Cable is around 100Eur.
