Module Data, Status, and Channel Configuration for DeviceNet 3-3
Over-Range Flag Bits (S8 to S11)
Under-range bits for channels 0 through 3 are contained in word 4, bits
8-11. When set (1), the over-range flag bit indicates an RTD temperature
that is greater than the maximum allowed temperature, a resistance input
that is greater than the maximum allowed resistance for the module or an
open channel is detected. The module automatically resets (0) the bit
when the data value is again within the normal operating range.
Data Format
RTD/resistance data is presented in engineering units x1. The engineering
units data format represents real temperature or resistance data provided
by the module. RTD data is reported in either degrees C or degrees F.
