interlock input point
Control target
equipment
Condition of interlock input
points :
All ON
is selected.
When
All ON
is selected, the state
change shown in the left figure can
initiate the interlock control function.
Example 2)
Even if the interlock input point recovered from the communication error
meets the specified condition, the interlock control function cannot be
initiated.
When
Any one or more of the groups
ON
is selected, the state change shown
in the left figure cannot initiate the
interlock control function.
Example 3)
When a communication error occurs in an interlock input point and,
consequently, the specified condition is met, the interlock control function
cannot be initiated.
Even when
All OFF
is selected, the state
change shown in the left figure cannot
initiate the interlock control function.
The condition of interlock input
points is not met.
Although the condition of interlock
input points is met, the
communication error in the control
target will not allow initiating the
interlock control function.
Even when the control target
recovers from the communication
error, the interlock control function is
not initiated.
In this case, once the condition of
interlock input points has become
invalid and then, when the condition
is satisfied again, the interlock
control function can be initiated.
