Hi. For some reason, column B is not converted to the time format after converting text by columns in an Excel csv file. The data in column B remains in the form at original float type. What could be the reason?

@_Faeton_: Thank you for subscribing and your support to my channel. Unfortunately, I have not experienced it before. Make sure you set up the date and time correctly to the PLC. All elements (including the milisecond) need to be included in the array in the right order. Or should it be from your excel software?

I fixed it. OS of PLC works with ' . ' symbol, and Excel works with ' , ' in type of variable. You need to make the conversion ''find and replace'' ' . ' on ' , ' in column B after applying the required time format. @@SYPHOANG

Nice video. I am trying to do something similar with a compactlogix 5380. do you have any suggestions?

@SYPHOANG 10 месяцев назад

@dr.pancake1279: Is it a later version or bigger Compactlogix PLC? I think you should have a more dedicated device for data logging.

Hello Mr. Hoang , I have a questino , how can you expand the amount of tags to log? and also , Can this routine be use to read from the file created?

@SYPHOANG Год назад

@sergioalbertoperezvidales7601: Unfortunately, I don't think that is possible.

Great example. Can you create batch logging using your example? Also, can you read the log files from the sd card over the network?

@SYPHOANG 3 года назад

@Amonlath: I am not very sure what "batch logging" is. This sampe code from Rockwell actually is very limited with only 10 REAL/Float registers/variables to be logged to the sd card. How about INT variables or DINT and REAL together or more than 10 source variables. It's possible but Rockwell definitely needs to improve it. I don't think you can read the log files over the network. Thank you for subscribing to my channel. To be honest, I would recommend to use HMI for data logging instead of PLC.
