Abstract
A programmable controller includes a main processor which executes a user control program. The main processor is interrupted by a support processor which operates as a real time clock. The interval between interrupts is determined by instructions within the user control program and may be dynamically altered when required. The main processor executes a user created interrupt routine when each interrupt occurs.
