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.

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
