I/O data mapping
I/O data transfer takes place via the MCI interface.
• The I/O data are accessed via the port blocks
MCI_IN
and
MCI_OUT
. These port blocks are also
referred to as I/O data channels.
• The
MCI_IN
port block maps the received data objects.
• The
MCI_OUT
port block maps the data objects to be sent.
• To the scanner, up to 10 data words (max. 20 bytes) can be sent.
• From the scanner, up to 8 data words (max. 16 bytes) can be received.
• The ports/function blocks of the I/O data objects are interconnected with the Lenze »Engineer«.
