Deadbanding for Ethernet Modules

Ethernet network modules with appropriate firmware (minimum revision 0300 for an FP-1600, any revision for a [c]FP-2xxx, cFP-180x, or FP-1601) can apply deadbands to the analog and count input channels of connected I/O modules. The deadband is a filter that enables you to specify the percentage change required in order for a signal to be transmitted to any clients. For example, consider an analog input channel with a range of 0-10 V and a 1% deadband. This channel transmits new values back to clients only when the voltage has changed more than 0.1 V. Signal changes less than 0.1 V are ignored, allowing you to filter out noise and reduce the use of network bandwidth.

Follow these steps to configure a deadband:

1. Select the I/O module under Devices and Interfaces or Remote Systems.
2. Click the Channel Configuration tab.
3. Select an analog or count input channel.
4. Under Data Configuration, enter a value for Percent Deadband.
5. Click Apply.
