4.4.1 "Logic" runtime software
"Logic" refers to the use of logically combined control signals without Motion functions. When the
"Logic" mode is used, the controller solely controls the motion sequences via logically combined
control signals.
4.4.2 "Motion" runtime software
The "Motion" mode makes it possible to execute more complex motion sequences than with the
Logic mode.
In the case of a Motion system, the whole motion control (Motion) of the axes to be controlled takes
place in the controller. The higher-level controller generates the motion profiles for all Motion axes
and transfers the data to the axes via EtherCAT.
A Motion-application...
• ...makes special demands on the cycle time and real-time capability of the bus system between
the controller and the connected field devices.
• for instance is to be used if the axes to be controlled are to be traversed in a synchronised
manner or position setpoints are to be transmitted.
Functionality
• Programming PLC functionality according to IEC 61131-3.
• SoftPLC functionality for executing PLC programs.
• The multi-tasking Windows CE operating system processes the PLC
programs cyclically.
Performance
The "Logic" mode defines the program function. The performance of the entire
automation system results from the interaction of the runtime software and
the target system in each case. The system performance thus depends on the
processor of the respective controller, and on other factors.
