8.1 Access to process data / PDO mapping
The process data are transferred via the MCI/CAN interface.
 Max. 8 words (16 bits/word) per direction can be exchanged.
– 2 x 4 words via the input ports CAN1_IN and CAN2_IN
– 2 x 4 words via the output ports CAN1_OUT and CAN2_OUT
 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 port/function block interconnection of the process data objects (PDO) takes place
via the Lenze »Engineer«.
