2 Product description
Each data memory is implemented as a memory stack. The individual memo-
ries are read out in FIFO or LIFO mode.
XML data The received data are extracted and stored type-specifically in different mem-
ories (one memory per value).
Binary data The received data are not extracted or interpreted. Only one memory exists for
a connection in binary mode.
Read-out
methods
Data elements are taken out of the memory in the order in which they were
stored there (FIFO). The reverse method, in which the data element stored last
in the memory is taken out first, can be configured (LIFO).
Each memory is assigned a common maximum limit for the data which can be
saved. If the limit is exceeded, the Ethernet connection is immediately closed
to prevent the reception of further data. The data currently received are still
saved, i.e. the memory is increased by 1. The memories can still be further
processed. The connection can be re-opened via the EKI_OPEN() function.
