System Values
Main process duty cycle <0-100> [40]:
The ratio between the time allocated to the main process of the application (including higher
priority tasks such as MDLC reception), and tasks of lower priority.
The objective of this parameter is to enable lower priority tasks to perform even when the
application is busy.
Time between BURSTs <0-10000> *10mSec [5]:
At the end of the main process and after the timeout specified in this parameter, the system
checks for bursts awaiting transmission. If the period of time between bursts has not yet
elapsed, the possibility exists to add new bursts to the buffer during the next scan.
Max. EVENT timer value <10-1500> *10mSec [1000]:
This parameter defined the maximum time that the “event timer” can be activated (in units of
10 msec).
The event timers can be activated via the SetTmr function in relation to events that have been
received via GtEvnt. The timers and the events are accurate to 10 msec. The timers are
activated when the event actually takes place (and not when GetEvent was performed).
Increasing the maximum time consumes about 4 bytes per time unit.
Total number of EVENTs (Status/Timer) <10-300> [150]:
Together with the previous parameter, this parameter defines the number of events and event
timers that can be received simultaneously.
Increasing the number of events consumes ~35 bytes per event.
Ladder received-frame-sequence queue size <4-300> frames [100]:
The maximum number of frames that can be stored in the frame sequence device. If more
frames arrive, an error is issued to the Error Logger.
Number of BURST destination Buffers <0-6> [4]:
The number of frames for which a burst can be created during the same scan.
RAM size for dynamic allocation <500-32000> K-bytes [28000]:
The amount of memory reserved for dynamic allocations at runtime.
C programs require dynamic allocations. Therefore, the value of this parameter should be
determined according to the amount of memory required by the C programs, or according to
the number of C program blocks.
Number of entries in the dynamic Site-Table <0-2000> [100]:
You can expand the regular site table (a Database Builder system table) using the dynamic
site-table which is accessible via “C” Toolkit.
