References by DeltaV modules to certain conventional, CHARM and WirelessHART I/O parameters (referred to as signal-bearing parameters) can require an I/O software license.
An I/O channel can cause a demand for only one I/O license. This means that multiple references (by one or more modules) to the same signal-bearing parameter result in the demand for only one license.
If modules are using multiple signal-bearing parameters that are part of a single channel, (for example, certain Pulse Count Input channels or HART-enabled AI or AO channels), the system only requires one license. The system consumes a single license of the most expensive type used. The license costs are (from highest to lowest): AO, AI, DO and DI.
The tables show the signal-bearing parameters that can trigger license demand for discrete and analog I/O.
