7.1 Access to process data / PDO mapping
Process data (MCI-PDOs) are transferred via the MCI interface.
 A maximum of 16 words are exchanged per direction.
 The process data are accessed via the port blocks LP_MciIn and LP_MciOut. These port
blocks are also referred to as process data channels.
 The port block LP_MciIn maps the received MCI-PDOs.
 The port block LP_MciOut maps the MCI-PDOs to be sent.
 The port/function block interconnection for the process data objects (PDO) is carried
out with the Lenze »Engineer«.
