Nice example hahaha

you dont convert string to byte
Byte is a size in length of bits.
The byte can be on type string or int or whatever. Please use a translator and ask a full question. We cannot help on the above post....or lack there of

Havent tried this but you could try and wire your start signal through the drives relay output (set to no fault) and then into start.......Just wondering how the atv61 would have started when powering up with a start signal. Should have given the same problem

You do not have a server license on that pc. Only a viewing or operating node license

Contact schneider directly. Not sure if that software still needs to be paid for or not. They can tell you. Last time i connected to a nano it worked in windows 98 command prompt.
Is the plc run light on?
-
Look at tm241 or 251 plc from schneider. Or most codesys based plc have web visualization. You write plc code and build pages that can control the logic like a scada or hmi.
If on a wifi you can then just type in the address on your mobile devices internet browser.
There are lots of security features available etc.
There are a lot of videos on youtube regarding somachine (schneider) web vizu or codesys web vizu.

What m221 are you using? And what communication will you be using? If using Modbus rs485 or Modbus Tcp/ip it shouldnt be a problem at all

By Serial line it means( for the tm221) modbus rs485 or rs232.
If you have a modbus port (not ethernet) it is usualy a rj45 connection. And for schneider pin 4 and 5 on the 8pin rj45 plug will be used for the coms, ons both sides of the cable.
But you cannot use a normal ethernet switch for this. You get rs485 splitters and extenders if you cannot make one cable run. Also modbus rs485 is limited in meters.
How far are your plcs apart?

Hi Wouter
On the other forum you mentioned that it is 2 tm221 plcs. If you have ethernet ports you can use the read_var and write_var function blocks
Like below
If using serial comms you can use the io scanner function. Select the serial port the change the protocol to modbus serial io scanner.
-
With Opc on a pc it is done directly. Nothing needed on plc. But if you can do some coding on visual basic you can write your own protocol. But bein unitelway that might be a bit of a problem

The problem is finding it.
I would contact the people that sold it toyou and let them run around. Or contact your local schneider SI

I am looking everywhere and cannot find the hotfix they mention. Your version of unity is no problem. Just need the hotfix. I will look and find the answer

You can change the application from main to secondary as shown below. You need to select the target and then in the below property inspector.
Also yes you could just stick in a usb stick that is formatted in fat32 (make sure to format it)
I would try to fit all on the main drive 1st. Then go to the usb stick option.
-
When you build the target, have a look at the size of application in sram and dram. Your touch screen has only so much memory. So either you must put in a cf card, or a usb memory stick. Then the webgate files can reside on the secondary drive.

I just realized I assumed it was unity pro. Seeing that you asked in other post regarding somachine i will have to go take a look and come back to you

Hi
Just for clarification do you want a comment next to the action name in the project browser? If so I dont think you can. If you however right click on the action and go to properties there is a comment section.
What I normally do is put a comment next to my step and mention which action is run in that step.
Hope I understood correctly

All panel manufacturers sell these. It comes with double sided tape. If you stick it correctly on a very clean surface it normally holds. but if done sloppy it comes off very quickly
-
what plc and software?
-
look for hysteresis function block
-
Just put the coil and type in any name. A popup will display asking you to create a variable. If you only want to use it in that pou just press enter. If you want to use it in other sections of your program select in the popup global variable. You do not have to give it an address.

Those part numbers do not come up in the scheider catalog. Which makes me think they are country specific. What are your needs for the project so we can recommend a more generic schneider screen. SEA is probably for Schneider electric Asia. I started searching without the SEA and saw those part numbers come up. Its a normal hmigtu.
Ok so the hmidt542 is the screen part and the premium box is the cpu with all the ports. Think of it as a normal xbt in two halfs.

You will have to use actions. Create a new conditional action and tell it which popup to open or close

You cannot give the schneider drives a start signal on power up. It wont start and will most probably give some error code
