Technology DBs
Technology DBs can be used in the user program to read the actual data of
technology objects such as the actual values and status of an axis, or error
information.
Technology functions
The PLCopen-compliant technology functions are called in the user program of the
PLC. Technology functions form the command interface to technology objects. The
output parameters of technology functions can be made available in the user
program to control the status of Motion Control tasks.
Technology objects
Physical drives are mapped to technology objects which describe their properties.
Each technology object is maps itself to a technology DB in the STEP 7 user
program where it indicates its status. Technology objects can be interconnected
and logically linked to hardware components. All technology objects such as axes,
cam disks, cam runners, measuring sensors or external encoders are configured in
S7T Config.
