4.8.2 Task and timing frame
The task frame of the system mainly consists of a constant change of system components and user
components.
[4-4] Distribution of the system interval
System components:
• Provision of the setpoint data for the control and actual data of the control
• Maintenance of the communication links on SDO and PDO level
• Processing and evaluation of the device status
• Parameter/services and error management
User components:
• Motion Control basic functions (MC)
• The basic functions enable a more comfortable access for motion control of the drive.
• For the »9400 ServoPLC«, the basic functions in »PLC Designer« are available as separate
system blocks which can be inserted, if required, into the control configuration and which
then can be accessed from the IEC 61131-3 program via the corresponding system variables.
• The basic functions are described in detail in the "Basic drive functions" chapter.
• Creation of the task images for the PLC tasks
• PLC part freely programmable by the user (User PLC).
System = system components
MC = Motion Control basic functions
