  6. Converting ToolboxScope of Functionality – Process interface Introduction • The interface to the process is based on the value on the function block input parameter lineAxis. The following alternatives are implemented: • lineAxis = TO#NIL: • There is no master axis specified. The coupling is based on variables of the I/O-structure sLTCConfigType. • lineAxis = TO#driveAxis: • The master axis is a speed controlled axis. The reference diameter of the axis has to be specified. • lineAxis = TO#posAxis: • The master axis is a linear positioning axis. • lineAxis = TO#externalEncoderType: • The master axis is a machine encoder.
