8 Process data transfer

8.1 Access to process data / PDO mapping

The process data (MCI-PDOs) are transferred via the MCI interface.

 A maximum of 16 words is exchanged for each 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 MCI-PDOs received.

 The port block LP_MciOut maps the MCI-PDOs to be transmitted.

 The port/function block interconnection of the process data objects (PDO) is made via

the Lenze »Engineer«.
