Accessing process data / PDO mapping
The process data (MCI PDOs) are transferred via the MCI interface.
Max. 16 words are exchanged for each direction.
The process data are accessed via the port blocks LP_MciIn and LP_MciOut. The port
blocks are also called process data channels.
The LP_MciIn port block maps the MCI PDOs received.
The LP_MciOut port block maps the MCI PDOs to be transmitted.
The port/function block interconnection of the process data objects (PDO) is made via
the Lenze »Engineer«.
