7.2.2.16

This parameter defines the minimum (absolute) value change of the Modbus data before the new value is

written to the associated Status Group Object. This avoids excessive sending when making minimal value

changes.

Option

0 ... 100

Note

When calculating the Device x Deadband parameter, always take account of the type and resolution of

the Modbus data points.

Example

The Modbus server stores the voltage value of 230 V as 2300 in the Modbus register. For a minimum

change in value (absolute value) of 0.5 V, the deadband should be set to 5.
