6.8 Interlock Release
The interlock action holds the event state even if the measured value is out of the event zone after it
enters the event zone once. The interlock release can be made by digital input (DI) [optional], or
communication [optional] other than the key operation.
For the Interlock release by communication, refer to the Communication Instruction
Manual (IMR02C16-E).
To validate the Interlock function, it is necessary to set Event interlock 1 to 4 (EIL1 to 4)
to “1: Used” in 8.5 Engineering Mode (P. 8-120).
• The following example shows how the interlock is released.
