Synchronized actions
1. Auxiliary function output
While a workpiece is being machined, technological functions
(-> auxiliary functions) can be output from the CNC program to the
PLC. These auxiliary functions control, for example, ancillary
equipment on the machine tool such as the sleeve, gripper, chuck,
etc.
2. High-speed auxiliary function output
The acknowledgement times for the -> auxiliary functions can be
minimized and unnecessary halts in the machining process
avoided for time-critical switching functions.
Synchronized axes
Synchronized axes require the same amount of time to traverse their
path as -> geometry axes for their path.
System memory
The system memory is a memory in the CPU, where the following
data is stored:
· Data required by the operating system
· The following operands: Timers, counters, flags
System variable
A variable which exists although it has not been programmed by the
-> parts program programmer. It is defined by the data type and the
variable name, which is prefixed with $. See also -> User-defined
variable.
T
Teach In Teach In is a means of creating or correcting parts programs. The
individual program blocks can be input via the keyboard and executed
immediately.
Positions approached via the direction keys or handwheel can also be
stored.
Additional information such as G functions, feedrates or M functions
can be entered in the same block.
Text editor
-> Editor
Tool
Software tool for the entry and editing of -> parameters of a parameter
block. Tools include:
· -> S7 Configuration
· S7 TOP
· S7 Info
Tool
A tool employed to shape the workpiece, for example, a turning tool,
milling cutter, drill, laser beam, etc.
