be started after that. This means that with this setting the actual values are transmitted
right before the set values are read.
The exact time for actual value transmission to the fieldbus processor alternates because
of the controller interrupt's computing time. Therefore, a time frame of 62.5
µs is set. In
the example shown a controller cycle of 5 was set. Therewith, transmission is carried out
within a time frame of 312.5
µs to 375 µs after the sync event has taken place (at sync
offset 0
µs). Additional time must be calculated for the transmission to the fieldbus, as the
fieldbus processor requires time to receive the data from the controller and to transmit it
onto the fieldbus buffer.
4.4.15.1 Parameter IDs for the Real Time Lists
The contents of the real time lists in the controller are configured at system commission-
ing by means of a service channel. These are then exchanged in real time. For each di-
rection (Consumer and Producer) there exist two lists in which the values of a maximum
of 16 parameter Ids can be transferred in each case.
The IDs of the Producer and Consumer lists are represented in ProDrive as a two-dimen-
sional array[2][16] in each case. The lists can then be opened simultaneously in ProDrive.
All the data can thus be visualized in a clearly laid-out manner.
4.4.15.2 Access Counter for each Real Time List
The number of accesses to the Producer and Consumer lists is represented in each case
as a one-dimensional array[2]. The lists can then be opened simultaneously in ProDrive.
All the accesses can thus be visualized on-line in a clearly laid-out manner. The access
counters are writable parameters, so that the counter statuses can be set externally, e.g.
to 0.
Using a further two parameters it is possible to display separately for Producer and Con-
sumer, which list was last accessed in each case.
