Revision 13 EN - 02/2023
11 Programming model
The data, exchanged by the PMM via the upstream PLC field bus can be split into four parts:
1. Configuration data (read only, byte 12-35)
2. Variable (read only, byte 40-77)
3. Status (read only, byte 10-11)
4. Command (write only, byte 11)
In the registers, the data is available in the following format:
Field bus Format
PROFINET
®
, PROFIBUS
®
Motorola-Format, Big Endian
Devicenet™, Ethernet/IP™ Intel-Format, Little Endian
EtherCAT
