FB Scan Time OB1

---

Calculate the execution time for the PLC of the code between the two call to this function. Normally this Function is used on a OB1 like this:

Example: OB1

 "FB Scan Time OB1"(CalculateRuntime := false);
 ...
 PROGRAM ..OB1...
 ...
 "FB Scan Time OB1"(CalculateRuntime:=true);

• Runtime: Max / Min / Average : of the runtime
• LastScan: Max / Min / Average : of the complete cycles: means the time between two run of the OB1
• ComTime: Max / Min / Average : of the time not used at Runtime. Normally this time corresponds to communications
• Reset: when TRUE resets all values. There is an autoreset also the first 10s of the PLC startup.
