Circular inhibit [CHECK 181]

Circular inhibit: tags 1FW/YS002OA and 1FW/YS004 inhibit each other

Circular alarm inhibits have been detected. Alarm inhibit action may be unpredictable.

In the database for a graphics system, two tags inhibit each other. That is, if one goes into alarm, it is supposed to inhibit alarms on the other. The actual effect is not necessarily predictable and probably cannot be counted on. Unreliable operation of alarm inhibits is not desirable for the operators.
