Parallel Port (Version HG 71912YA)
It is possible to select a parallel interface for simple applications (e.g. for a PLC without
communication controller). The least significant 15 code bits and a data ready pulse
will be output. This pulse with configurable duration is generated for each changing of
code. Parallel data are permanently available.
In order to operate the system exclusively, all other signals and lines (except CAN) are
available on the flat band cable as well. The outputs D0-D14 as well as Data-Ready
are not current limited. The output
POSI
is realized via a switched 20 mA current gen-
erator! The output switch has 24 V and can thus be connected to a PLC.
A timing diagramm is shown in section F on page 57.
