Deadbands
The Monitored Measured points (M_ME_NA and M_ME_NB) will generate
events only if the data value changes an amount greater than or equal to the
configured deadband value.
For example, with the following point configured:
If the current value for this point is 130, it would only generate an event, only if:
NEW VALUE is less than or equal to 30
OR
NEW VALUE is greater than or equal to 230.
You can set the deadband for each Monitored Measured point through the
configuration file.
The Client may also dynamically change the deadband for each Monitored point.
The Client may send one of the following commands:
Type
Command
110
Parameter of Measured Normalized Data (M_ME_NA)
111
Parameter of Measured Scaled Data (M_ME_NB)
112
Parameter of Measured Short Floating Point (M_ME_NC)
