  1. does it ask for a password when you are trying to connect to the plc? or when you are trying to upload the program?  
  2. starting with embedded webpages

    If i was you i would look at any codesys based plc. (many manufacturers use codesys based software) You get webvisualization in codesys where you could build a Scada type web screen (hosted by the plc) that can be accessed on normal web browser. there are a few example videos on youtube. I have only used it a couple of times so not sure about the limitations regarding amount of data on a page etc. but for low cost this works well
  3. I dont think there is something for the Zelio like this. Just a smart Relay, not a plc. The Zelio initializes all inputs and outputs when there was a power failure or program stopped and started again (Except for certain functions that have a latch option). But saying that maybe just set a Marker bit at the end of your program and use the marker in the program. This will only set after one scan was completed. For more info look at the zelio help file and search for "How the Smart Relay Behaves in the Event of Power Failure" Hope this helps
  4. You use animation tables to view values online Also it could be that the byte order is swapped around of the register you are reading. Try reading a register which has a constant small value in like date or something to do your tests  
  5. I have no experience with the machines....but from what i have heard they are expensive and you dont want to mess around with "cheap" brands. I would stick with brands that are into the terminal and pinlug business like Phoenix contact or Weidmuller. Phoenix contact has a handheld unit but its pricing is absurd. Almost the same price as the desk standing device. The devices you posted links for and the devices i am talking about are worlds apart pricing wise.
  6. Wasan explained it perfectly. But just in case here is a video....not in english but you will get the idea   https://www.youtube.com/watch?v=ejsIh7hmbXo
  7.   Here is a quick video displaying the basics.  and attached is the user manual. Also in unity search they show some info regarding the card.  Youtube also has some videos regarding variables and how to create them in excel etc.   ech0200.pdf
  8. Here is a screenshot of where you enter the tag name and address. You do this in the elementary variables section. If you have a lot of tags to create, then create the 1st one in unity in the elementary variables and select the tag then right click. Then export selected tags. Export to a txt file. You could open this in excel and populate everything quickly there and then import the files by right clicking on variables & fb instances and selecting import. Regarding the high speed counter, what is the part number of the card?
  9. Just to make it clear do you want the value to always show as a positive? If so you can use the abs function block
  10. pm me an email and i will send an old program  
  11. Try loading firmware again on cpu. This should clear all memory in plc. Also look for firmware updates for that plc on schneider website. Personlly havent had a problem like this. Will keep digging maybe i find something
  12. ***Didnt read the part about working for 2 hours...hence the edit***   Sorry for even asking this but we are humans. Are you sure the expansion card installed in expansion slot is the same part number than configured in the software? Also did you check the plug in area of the expansion card if there are maybe physical damage? Also is the correct voltages wired to the expansion card?
  13. If you go to windows control panel......then system......then device manager......when you plug the cable in on pc do you see a driver open under COM PORTS?  
  14. I tried to find the gen controller modbus manual but can only get in upon request. Can you attach it here.  Just on thing i see. You said that the 1st read you want to start at 42497 and second on 42753 yet in your setup you start on 42496 and on 42753. There normally is a one bit offset with modbus. Just thinking maybe you are reading from the middle of a floating register or something on those lines....If i have the modbus manual of the controller it would make things clearer
  15. Magelis-HMI XBT012110

    I dont think you will be able to upload from the hmi....This option needs to be selected when the original program was downloaded to the screen. If not there is no way of uploading the program from the hmi
