16.8 “High Performance Mode”
With RTC6 Ethernet Boards,
eth_set_high_performance_mode switches on (off)
the
• “High Performance Mode”
“High Performance Mode” is only effective with
list commands. If it is switched on ( Mode = 1), the
RTC6 DLL no longer waits for a response from the
RTC6 Ethernet Board after each telegram.
Instead, the RTC6 DLL now acknowledges several
telegrams at a time. Therefore, more list commands
per time can be written into the RTC6 List Memory (=
“higher list download performance”).
The RTC6 DLL always waits until the RTC6 Ethernet
Board has acknowledged all previous list commands
with:
• Control command calls
• set_end_of_list
• list_return
To ensure that all list commands are written to the
RTC6 List Memory, the list command block should
always be terminated by set_end_of_list or
list_return when:
• A list is started with
– /Slave-START
– /START
• A list command block is not directly followed by
a control command
However, a significantly higher rate can only be
achieved, if you:
• Write correspondingly larger
list command blocks
• Avoid that by calling a control command the
list command blocks are confirmed prematurely
