Hello markozg
Yes you can can have an FB/FC code written in 2 different languages, it will work and there is absolutely no problem with this.
Yes, you can have have FB1 written in LAD and FB2 in STL and it will work. Some more background info: LAD and FBD are STL, but simply displayed differently. That is why you can always change the display from LAD or FBD to STL and see the actual STL code and that is also why it is perfectly ok to have one or more Segments in a block in STL and others in either LAD or FBD. Even if you program in higher level languages (e.g. SCL, CFC, S7-Graph, S7-HiGraph), they all compile down to STL which is then compiled to the S7 machine code (MC7) when downloaded. I hope this helps P.S: The above applies to S7-300's and S7-400's but not to S7-1500's. |
