4.6.3 Disabling Individual Interrupts
Individual interrupt devices can be temporarily or permanently disabled by driving an
associated special auxiliary relay. The relevant coils are identified in the tables of devices in
chapter 6. However for all PLC types the head address is M8050, this will disable interrupt
I0oo.
Driving special auxiliary relays:
• Never drive a special auxiliary coil without first checking its use. Not all PLC’sassignthe
same use to the same auxiliary coils.
Disabling high speed counter interrupts
• These interrupts can only be disabled as a single group by driving M8059 ON.
Further details about counter interrupts can be found in the following section.
4.6.4 Counter Interrupts
Identification of interrupt pointer number:
Example:
The sequence programmed after the label
(indicated by the I030 pointer) is executed once
the value of High Speed Counter C255
reaches/equals the preset limit of K100
identified in the example HSCS.
Additional notes:
• Please see the following pages for more details on the HSSC applied instruction.
- High Speed Counter Set, HSCS FNC 53.
