Hi all, I have 3 Questions of Siemens PLC program.
1. I need to write a PI control in the program. As I know I set D_set as 0 then it is a PI Control. But what is the meanings of the others ?? I have no idea what value or type should I set in order to be a PI control function
2. What can I do if i want to find the max. and min. value of 9 temperature readings ? Does any functional blocks can do that ?? Or need to write a program to compare all the value by myself ?
3. Since in the program, I need to check the time schedule to do some actions, but I have no idea of time schedule . Does any functional blocks can do that ?? If yes, will it be configed by hours? days? weeks? months? years? or any format?
Can anyone help me ?? PLZ~~
