5.2.2.6 Channels 1 to 32 with analogue and/or digital values
Every analogue device channel can contain alarm messages, operating messages, measured values, test mes-
sages and descriptive text. Both analogue and digital information can be transmitted.
AT&T = Alarm type and test type (internal/external)
R&U = Range and unit
For details on the channel description refer to Kapitel 5.2.5.
5.2.2.7 Float = Floating point value of the channels
Representation of the bit order for processing analogue measured values according to IEEE 754
S = Sign E = Exponent M = Mantissa
5.2.2.8 A&T = Alarm type and test type (internal/external)
The alarm type is coded by the bits 0 to 2.
The bits 3 and 4 are reserved and always have the value 0.
Bit 5 usually has the value 0 SMI472 and represents the digital value of the status
This column is relevant for the SMI472 only.
Bit 6 or 7 is usually set when an internal or external test has been completed.
Other values are reserved.
The complete byte is calculated from the sum of the alarm type and the test type.
