Timed Interrupt Program Example
In the following example, we do some initialization on the first scan, using the first-scan contact
SP0. The interrupt feature is the HSIO Mode 40. Then we configure the HSIO timer as a 10
mS interrupt by writing K104 to the configuration register for X0 (V7634). See Appendix E,
Mode 40 Operation for more details.
When X4 turns on, the interrupt will be enabled. When X4 turns off, the interrupt will be
disabled. Every 10 mS the CPU will jump to the interrupt label INT O 0. The application
ladder logic in the interrupt routine will be performed. If X3 is not on, Y0–Y7 will be reset to
off and then the CPU will return to the main body of the program.
