Note

Subroutine blocks are not available for the Series 90-20 PLC or for the Micro.

The use of subroutines is optional. Dividing a program into smaller subroutines can simplify programming, enhance understanding of the control algorithm, and reduce the overall amount of logic needed for the program.
