Registers 0 to 15 hold the latest numeric data from configured analog

current input channels 0 to 15. This data has been filtered (50 or

60 Hz filters) and, if the cycle averaging option has been enabled,

averaged together. See figure 4.1. The data is in 15Ćbit signed integer

format. The data is displayed in engineering units specified by the

Maximum Scaling Value (register 24) and Minimum Scaling Value

(register 25). Unscaled values will range from 0 to 4095. If a channel

is not configured, its data is held at zero.

High High alarm. See figure 4.2. A bit is set in this register whenever

a channel's input value exceeds the configured High High alarm limit.

The bit is reset when the input value returns to a level below or equal

to the configured limit.
