1. Write all pending system information (see system objects) to the CPU and reset all
currently acquired send triggers and commanded entries. If no such data is currently
pending, there is no write procedure in the basic cycle.
2. Read
all
data of the send objects that were assigned to the
fast cycle
. If no objects were
configured for the
fast cycle
, this read procedure is omitted in the basic cycle.
3. Read data from some of the send objects that were assigned to the
normal cycle
. How
many objects per basic cycle will be read can be set by the user. Refer to the
Max. read
parameter below.
4. Write data of some of the currently pending receive objects.
How many objects this can be as a maximum per basic cycle can be selected by the
user. Refer to the Max. write parameter below.
If less received data is currently pending than his permitted as maximum per basic cycle,
only this subset is written in the basic cycle.
If there are currently no received data from the remote partner, this write procedure is
omitted in the basic cycle.
5. Cycle pause (optional) to relieve the TIM and backplane bus communication.
With the
Max. read
and
Max. write
parameters and by specifying how many objects are
assigned to the fast cycle, the user can determine the duration of a basic cycle. Essentially,
this specifies how fast the fast cycle really is: It is identical with the duration of the basic
cycle. With the default 1 for the
Max. read
and
Max. write
parameters, the basic cycle has
the shortest possible duration.
It must also be taken into account that the make-up of the basic cycle decides how long
TD7onTIM requires to read all the data of the objects assigned to the normal cycle once. If,
for example, 12 objects are assigned to the
normal cycle
and if
Max. read
is set to 2 objects
per basic cycle, it takes 6 basic cycle is until all the data of the 12 objects have been read
once completely from the memory areas of the CPU.
Parameters in the
read/write cycle
field
Name: Max. write
Range of
values:
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
values:
0 ... 32000
