FB 230 in Step 5

muneeb

Hi Legacy,

I know that there is FC91 equivalent to FB230 in Step 7. My question is, in FC91, when there is positive edge at SR input, it puts the data into DW4 of the relevant DB. is it the same function in Step 5 as well. 

If someone can provide me the help on FB230, i will be much thankful, i know it is siemens block and it has even a Block number as well.

Thanx

Hello muneeb,

follow this link:

Basic Functions Standard Functions Blocks Programable Controllers S5-95U, -100U, -115U, -135U, -155U

There you will find a description (PDF) for the basic functions. Look at FB 11 (Shift register word).

Many thanks... It is really helpful.

Regards,
