PDO mapping
The PDO mapping differs depending on the motion control to be configured:
Drive−based automation
(decentralised, with intelligent controllers)
Controller−based automation
(with a central control)
l
Direct data exchange between the IO system and
the controller without a master control.
Configuration with L−force Engineer
l
Direct data exchange between the IO system and
the control (IPC). Configuration via L−force PLC
Designer
l
Static PDO mapping (default setting)
l
Free mapping by means of a bus configurator (e.g.
PLC Designer)
l
Up to 10 RPDOs and TPDOs can be used
l
Up to 16 RPDOs and TPDOs can be used
The following representation describes the static PDO mapping (Drive−based automation)
