Acknowledge Tag
It allows to manage the acknowledgment of the alarm through PLC tags both bitwise (in case the alarm is programmed on the value of the single bit of a tag) and value.
This functionality is useful if there are multiple panels connected to a single PLC and you want to propagate the recognition made by one of the panels to the others on the network.
Tag
Select the Tag on which the alarm is mapped.
Activation Type
Define the type of alarm activation.
BIT: the alarm is raised when the bit reaches the TRUE value and is considered terminated when the bit reaches the FALSE value.
ACTIVATION VALUE: indicates the bit number inside the tag (from 0 to 15 if the tag is an INTEGER)
NEGATIVE LOGIC: inverts the bit value corresponding to true (value 0) and FALSE (value 1)
EQUAL: the alarm is raised when the tag assumes the value defined in the Activation value.
DIFFERENT FROM: the alarm is raised when the tag value is different from that defined in the Activation Value
BIGGER THAN: the alarm is raised when the tag value is greater than that defined in the Activation Value
LESS THAN: the alarm is raised when the tag value is lower than that defined in the Activation Value
IN THE RANGE: the alarm is raised when the tag value is within the range of values defined by Minimum Range and Maximum Range. The alarm is lowered when the tag value is out of range
OUT OF RANGE: the alarm is raised when the tag value is outside the range of values defined by Minimum range and Maximum range
