Rockwell Automation Current Input Module - Manual (Page 30)

4Ć12
If the specified channel has square root extraction enabled and does
not use engineering units, the flow information provided is in the
range of 0 to 4095. The data returned represents the following ratio:
Data Flow
4095
=
Flow (Maximum)
Set the Maximum Scaling Register (register 24) to 10000 in order to
read the flow information in steps of 0.01%:
Data Flow
10000
=
Flow (Maximum)
You can also set register 24 to the maximum flow value which will
allow a direct indication of flow.
Bits 8 to 11 are reserved for future use.
Bits 12 to 15, when equal to 0, enable the READYstate, which is the
default condition. When the module is in the READYstate, it is ready
to receive a configuration command.
When bits 12 to 15 are set to a binary value of 1, 2, or 3, their
operations refer to the channel specified in register 23:
D A binary value of 1 (RESET) resets the channel's configuration by
clearing its corresponding data register (registers 0Ć15) and
resetting its bit in the status registers (registers 16Ć21).
D A binary value of 2 (READ) locates the channel's current
configuration information in memory and loads it into registers 24
to 31.
D A binary value of 3 (WRITE) transfers the channel's configuration
information (registers 24 to 31) into the module's memory,
configures the channel, and then sets its bit in the status registers
(registers 16Ć21).
When bits 12 to 15 are set to a binary value of 4 or 5, they reflect the
AĆC power line frequency. The default is 60 Hz.
