Notice
Instruction Behavior
The GEI instruction behaves as follows:
- The GEI instruction enables execution of general periodic interrupt programs.
- Once the GEI instruction is executed, the enabled status is maintained.
- Interrupts set by a parameter can be executed after the GEI instruction.
- When the CPU switches from STOP to RUN mode, all interrupt programs
- When the CPU has switched from STOP to RUN mode, all interrupt programs are disabled by the DI instruction.
- To use general interrupt programs, execute the GEI instruction.
Automatic Enable
Interrupt programs of CPU types such as the PLC-AES/ES are enabled with the GEI instruction as a default. These CPUs do NOT need to execute the GEI instruction when the RUN/STOP key switch is changed from STOP to RUN.
