Description:
Users that are available for session management
The individual values involve the users of the logging function, which are
assigned the following functions:
0: Reserved for system functions: simultaneous recording, simulation, syn-
chronized action analysis
1: Reserved for system functions: determining program runtimes, multi-step
editor
2: Reserved for OEM applications
3: Reserved for OEM applications
4: Reserved for OEM applications
5: Reserved for system functions: trace
6: Reserved for system functions: trace
7: Reserved for system functions: trace
8: Reserved for system functions: trace
9: Reserved for system functions, action log
Description: The NCK sends and receives PLC VDI signals. The Trace function stores the
signals which have changed in each interpolation cycle in an FIFO memory
(first in-first out) having a size of MM_MAX_TRACE_POINTS.
The FIFO is written to a file (for the 1st channel: ncsctr01.mpf) when a
"trigger event" occurs (e.g. Cancel Alarm key, see MD22704
$MC_TRACE_STOPTRACE_EVENT and MD22700 $MC_TRACE_STARTTRACE_EVENT).
The machine data should be interpreted as bit mask. The corresponding VDI
signals are recorded depending on which bit is set.
Bits 1.. 6 describe which axial VDI input signals are recorded in the trace
(see .. TRACE_DATA_FUNCTION).
