Defining routines
A routine is a set of logic instructions in a single programming language,
such as ladder logic. Routines provide the executable code for the project in
a controller. A routine is similar to a program file or subroutine in a PLC or
SLC controller.
Each program has a main routine. This is the first routine to execute when
the controller triggers the associated task and calls the associated program.
Use logic, such as the Jump to Subroutine (JSR) instruction, to call other
routines.
You can also specify an optional program fault routine. The controller
executes this routine if it encounters an instruction-execution fault within
any of the routines in the associated program.
Selecting a System
Overhead Percentage The Controller Properties dialog lets you specify a percentage for system
overhead. This percentage specifies the percentage of controller time
(excluding the time for periodic tasks) that is devoted to communication and
background functions.
System overhead functions include:
• communicating with programming and HMI devices (such as RSLogix
5000 software)
• responding to messages
• sending messages
