Communication SFC's and SFB's

[agrosse 0]

Looking for some help regarding the LEN parameter for SFB 60 in S7? This is suppose to be the length (in bytes) of data that is being sent, correct? I am pretty sure that i have the correct length in bytes that i'm inputing but it keeps telling me that it's an incorrect length! Any thing that i may have overlooked or need to take into account that i have not??

No Crystall Balls in here, post the calling code.

Not sure about SFB 60, but AG_SND and AG_RCV use LEN and this is the number of bytes to be sent or received
