Overview
The WF 723 C positions up to three position-controlled axes, both independent of each other
and coordinated and combined. functions like linear interpolation, synchronism and chaining, in
addition to simple point-to-point positioning processes, are an important part of today's
automation tasks. Further possibilities, such as flying actual-value setting, external block
change, the use of tool offsets, zero point offsets and the output of M-functions, are also
offered by the WF 723 C module.
These functions are applied in:
•
Handling devices
•
Portals
•
Press feeding devices
•
Wood working machines
•
Storage and retrieval units
•
Special machines
•
Packaging machines
Furthermore, the roll feed function is integrated in the WF 723 C. The roll feed serves for fast
and exact positioning of highly dynamic conveyors
This functions is applied in:
•
Sheet metal working machines
•
Packaging and filling machines
To make all these possibilities available for the user, the programming of traversing programs
is the means to formulate information and translate it into a language understandable to the
WF module.
2.2
Traversing program
The program structure is defined according to DIN 66025. A traversing program consists of a
sequence of up to 200 traversing blocks and is assigned to a programm number.
The traversing program is situated in the RAM memory of the WF module and is buffered by
the SIMATIC S5.
In case of a RAM memory failure the RAM memory contents of the
WF module is lost.
The programming examples are displayed according to DIN 66025. Inputs
via COM 723 are entered in this format. The programs are stored in the
SIMATIC S5 and the WF in S5 format. See a comparison of DIN format and
S5 format in the chapter ”programming in S5 format”.
