PDO Process Data Objects serve for the fast transfer of processing data via
Multicast connection and are transmitted by simple CAN messages
without protocol overhead. Process Data Objects can be transmitted
event-controlled, synchronous to a system pulse sequence or on demand.
PDOs are divided into TPDOs and RPDOs.
PLC/IPC Programmable logic controller/industrial PC
RPDO Receive PDO
SC/O
SCS, SCO, SCV Short circuit/overload
Short circuit/overload sensor supply, outputs, valves
SDO Service Data Objects predominantly form point-to-point connections
between the server and client for the exchange of parameters for device
configuration. They enable write and read access to any entry in the object
directory of a bus node.
Status bits Internal inputs which supply coded common diagnostic messages.
TPDO Transmit-PDO
