0x0024 Validity period of the
process data on the
EtherCAT interface
In this memory register you have the option, to define the validity
period of the process data on the EtherCAT interface.
The next production must take place within the specified period,
otherwise the input data is marked as invalid. Output registers that
are supplied with process data via the Data Broker from this input
area then adjust themselves to the preselected safe values. You set
these values in the Memory Register 0x0021.
You can find detailed information on this topic in section "Data Broker

0x0027 Configure size of the
In-Mailbox
In this memory register you have the option, to set the size of the In-
Mailbox of the DPR
This value has a header of 12 bytes. When specifying the value, you
must
not
include the length of the header for the required data size,
however.
Make sure that the sum total of the values in the Memory Register
0x0027-0x002a does not exceed the configurable total size of the
DPR. This total size of 1024 bytes is made up as follows:
– Header: 40 bytes
– Configurable size: 984 bytes
