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)
by means of an example station structure:
