Inputs

Input	Data Type	Range	Unit	Default	Description
INFO	DINT				Identifier of the requested information.

Output	Data Type	Range	Unit	Description
Q	DINT			Value of the requested information or 0 (zero) if error.

The INFO parameter can be one of these predefined values:

Value	Definition
_SYSINFO_APPSTAMP	Compiling date stamp of the application.
_SYSINFO_BIGENDIAN	Non zero if the runtime processor is big endian.
_SYSINFO_CHANGE_CYCLE	Indicates a cycle just after an Online Change
_SYSINFO_CODECRC	CRC of the application code.
_SYSINFO_CYCLECOUNT	Counter of cycles.
_SYSINFO_CYCLEMAX_MICROS	Maximum detected cycle time in micro-seconds.
_SYSINFO_CYCLEMAX_MS	Maximum detected cycle time in milliseconds.
_SYSINFO_CYCLEOVERFLOWS	Number of detected cycle time overflows.
_SYSINFO_CYCLESTAMP_MS	Timestamp of the current cycle in milliseconds (OEM dependent).
_SYSINFO_CYCLETIME_MICROS	Duration of the previous cycle in micro-seconds.
_SYSINFO_CYCLETIME_MS	Duration of the previous cycle in milliseconds.
_SYSINFO_DATACRC	CRC of the application symbols.
_SYSINFO_DBSIZE	Space used in RAM (bytes).
_SYSINFO_DEMOAPP	Non zero if the application was compiled in DEMO mode.
_SYSINFO_ELAPSED	Seconds elapsed since startup.
_SYSINFO_FREEHEAP	Available space in memory heap (bytes).
_SYSINFO_NBBREAKPOINTS	Number of installed breakpoints.
_SYSINFO_NBLOCKED	Number of locked variables.
_SYSINFO_TRIGGER_MICROS	Programmed cycle time in micro-seconds.
_SYSINFO_TRIGGER_MS	Programmed cycle time in milliseconds.
_SYSINFO_WARMSTART	Non zero if RETAIN variables were loaded at the last start.

In the FFLD Language, the operation is executed only if the input rung (EN) is TRUE.
- The output rung (ENO) keeps the same value as the input rung.
The function is executed only if EN is TRUE.
ENO keeps the same value as EN.

In the IL Language, the input must be loaded in the current result before calling the function.
