Title: Are There Limits on the Number of Sheets in FB Subroutines for CompactLogix 1769-L32E Controllers? Hello, friends! Iām curious if there are any restrictions on the number of sheets within a Function Block (FB) Subroutine. Currently, I have 21 sheets in a single Subroutine. Could this potentially impact the functionality or logic of my system? I'm using the CompactLogix 1769-L32E controller and would greatly appreciate any insights or assistance you could provide. Thank you!

Thank you! I have a question about the impact of increasing the number of sheets on scan time. Will a larger quantity slow down the scanning process?
It seems that "FB" may not refer to Facebook. The issue with extensive "FB" routines arises when attempting to make online modifications; this is because the entire routine is loaded into the processor's memory.
Hey there! While the CompactLogix 1769-L32E does have some flexibility, having 21 sheets in a single FB Subroutine might be pushing it a bit. It's worth considering that too many sheets can complicate debugging and impact performance, especially as your logic becomes more intricate. Iād recommend breaking them into more manageable subroutines or using organized structures to maintain clarity and efficiency. Keeping things streamlined can really help when troubleshooting or upgrading down the line!
