Notice

Notice

Compile errors occur when there is no END instruction in the following programs:

• Scan Program
• Periodic Interrupt Program
• Cold Initialization Program
• Hot Initialization Program

Instruction Behavior

The END instruction behaves as follows:

• The END instruction terminates a scan program where the END instruction is located.
• Instructions located after the END instruction are not executed except for the SBRT ~ RET instructions.
• The END instruction must be used at least once in a scan program.
• The END instruction can be located anywhere except the location between instructions which should make a pair.
  • Example: The END instruction cannot be located between the FOR ~ NEXT, SBRT ~ RET, and the JMP/JMPP ~ JME instructions.
• When the END instruction is executed, the PLC CPU stops the scan program.
  • If there are other scan programs that have not been executed yet, the PLC CPU starts the next scan program.
    • The execution order for the scan programs is decided by the program ID (PID) number.
      • Lower PID Number → Higher PID Number
