Parameters in the TD7 Read / Write Cycle box
Name:
Max. write
Range of va
l-
ues:
1 ... 32000
Default:
1
Explanation:
This is the
maximum number of (different) data objects whose data is written
to the CPU per basic cycle.
If there are several messages of the same receive object in the buffer, only
the data of one message of this object is written per basic cycle.
As information, the
number of receive objects configured for the TIM in total
by the user is displayed above the input box beside
Number of configured
receive objects .
Name:
Max. read
Range of va
l-
ues:
0 ... 32000
Default:
1
Explanation:
This is the maximum number of da
ta objects whose data is read from the
CPU per basic cycle.
As information, above the input field beside
Number of configured send ob-
jects
, you can see how many send objects the user configured for the TIM
-
in the normal cycle and
-
in the fast cycle
.
Name:
Cycle pause
Range of va
l-
ues:
0 ... 32000 [ms]
Default:
1
Explanation:
This parameter specifies the duration of an optional pause between 2 basic
cycles.
A pause may be necessary if communication of other modules on the bac
k-
plane bus is disrupted
too much by the write and read jobs between the TIM
and CPU. This also applies to subscribers on the MPI bus (further CPUs or
PG) if the backplane bus is implemented as a party line. By setting a suitable
time for the pause, the other bus subscribers have
time for their communica-
tion.
Specifying a cycle pause may also be necessary to relieve the TIM itself; in
other words, when it becomes clear that it has too little time for other tasks
due to the fast read/write cycle.
