Accessing process data / PDO mapping
Process data are transferred via the MCI/CAN interface.
Max. 8 words (16 bits/word) per direction can be exchanged.
The process data are accessed via the port blocks LP_Network_In and
LP_Network_Out. These port blocks are also called process data channels.
The LP_Network_In port block maps the received MCI-PDOs.
The LP_Network_Out port block maps the MCI-PDOs to be sent.
The port/function block interconnection of the process data objects (PDOs) is made via
the Lenze »Engineer«.
