Thank you for video about SD operation. Will you make detailed video how to use DATALOG blocks? They are not mentioned in the user guide and programming guide.
Very well explained. Do you know one way to get a program running on a protected M221? My old coworker puted a password on a program, months later he got fired and now we don't have the program and the password and we need do some changes. We don't know what to do.
Hi there! There are different scenarios with protection: 1) Application protection, you must have the password otherwise you will need to start from scratch. 2) write protection: you can login and see the code so you can open other instance and manually create the code. 3) read protection: unable to read the code, same solution as 1. To sum up, if i were you i will start from scratch or find a backup somewhere.
Thank you for your time , Incredibly good explanation , please make how we can use interrupt ( time of day , startup .......) and Hardware interrupt in M221 like S7 1200 Siemens
Hi Hichem! Can you share with me some links with those functionalities to take a look? I have not played enough with the S7 1200 to know it well. In the Modicon M221 on the Configuration > Digital Inputs you can execute events also with the HSC. Once you do that you can see a POU on the Programming > Task > Event for that specific action. The other useful information can be found on the system variables %S and %SW to check them go to Programming > Tools > System object.
Hi Hichem! The module 12 is dedicated to HSC (simple + main) but I need to get an encoder first to play with it and then be able to make videos. Hopefully Jan 2022

Are prepare videos about HSC ?

Can use a normal SD card?
Hi Mohamad! You can but try to check the next video for further information: th-cam.com/video/vg1tbXEN_bU/w-d-xo.html
