  1. CX DESIGNER 2.0 and NS10-V1

    After I read the data from the CPU CF card and written in one continuous block, how do I display them in the data block table?
  2. I have managed to save a CSV file into the CF card in the PLC. How can I read the CSV file from the CF card in the PLC from the NS5 PT and show it in the Data Block Table?
  3. Logging of value of an address in CJ2M

    Thank you for your advise. 1. I have tried out DIST. I am able to record the values into an array for integer value, but not with real value. Does DIST works for real value? After I recorded the values in a series of addresses, eg. 5000, 5001, 5002, 5003, 5004, 5005, ... How can I display them in the form of a table where the number of values recorded varies? Attached are the project files that I used with integer value. 2. I have also tried to save the recorded values into a CSV file in a CF card at the PLC. But the value is hexadecimal. How do I save the value as an integer value. Eg. Integer: 239, save as 239 and not EF. Logging_CX_Prog.zip Data Logging_HMI.zip
  4. I want to create a series of logs on the value of at address 1000 at every 10 seconds in the PLC CJ2M. And later display these logged data on the NS5 PT Anyone can help me out on this? Thank you.
