MC-PreServo OB



Description

The organization block MC?PreServo [OB67] can be programmed and is called in the application cycle configured at the MC?Servo [OB91]. The MC?PreServo [OB67] is called directly before the MC?Servo [OB91].

Via the organization block, you can read out the configured application cycle (information in μs).

Structure of the start information

Optimized start information:

Name	Data type	Meaning
Initial_Call	BOOL	TRUE	In the first call of this OB during transition from STOP to RUN
PIP_Input	BOOL	TRUE	The associated process image input is up-to-date.
PIP_Output	BOOL	TRUE	The associated process image output was transferred to the outputs in time after the last cycle.
IO_System	USINT	Number of the distributed I/O system triggering the interrupt
Event_Count	INT	n	Number of lost cycles
		-1	An unknown number of cycles has been lost, e.g. because the cycle has changed.
Synchronous	BOOL	TRUE	The MC?Servo [OB91] is called synchronously with a bus system.
CycleTime	UDINT	Display of the application cycle configured for the MC?Servo [OB91] in ns
