make mistakes, some people do never make mistakes! I´m not programming that long but i have
seen a lot of different way's to convert a flowchart to a program in a
plc. Sometime it is easy to read but takes a lot of the internal cpu
(e.g. some graphical tools like Graph from Siemens or Hitachi). A big
disadvantage of these programs is that you need these tools to be
installed on your pc with the source code. If you don’t have
the source code than your F*ucked. The most functions i've seen are special made for
that company, mostly not useable for anything else. I've made a
standard for myself with universal and easy functions that can be
common used. Thanks for all who have helped me with some functions. - Step
- Functions to convert an flowchart to a plc program. With function blocks.
- Fast step
- Functions to convert an flowchart to a plc program.
A very fast methode! (aprox. 25 STL instructions per cyclus!) - Functions to convert an flowchart to a plc program.
- IO
- Functions to read inputs and write outputs or a combination of it.
- Timer using SFC64
- Functions using the internal clock function SFC64 "TIME_TCK"
- DB
- Functions to handle DataBlocks (only for step7
^{®}Plc!) - Mathematical
- Functions to calculate a mathematic function.
- Mathematical
- Functions for making (easy) mathemetical calculations. (Most likely as example for own functions).
- XY axis
- Functions for axis movements on PLC's
You can download all functions as a library (step7 v5.3). Or as STL source in the separate pages. |
