NOVUS AUTOMATION 16/16
REGISTER 2 – FIRMWARE VERSION
Indicates the device firmware version, as it is shown in the examples:
If the version is “1.00”, value “100” will be read. If the version is “2.04”, value “204” will be read.
REGISTERS 241 TO 255 – DIGITAL INPUT STATE FLOATING POINT VALUE
Indicates the state of the digital input through the floating point value associated with the input channel by the user when
configurating.
REGISTERS 735 AND 736 –ALARMS STATE
Bit array where each bit informs the state of the corresponding alarm (0 = alarm off, 1 = alarm on).
REGISTERS 774 AND 775 – CONSTANT FLOATING POINT VALUE
Informs the constant value “123456.125”, purposed to test the floating point format when reading registers.
REGISTERS 776 TO 791 – DIGITAL INPUT COUNTING VALUE
Has the counting values of the digital inputs (32-bit unsigned integer format). Available only in firmware version 1.10 or
higher.
REGISTER 990 – LOGGINGS START AND STOP COMMAND
When configured the start and/or the stop of the loggings by a Modbus command, it allows to start or to stop the loggings
disregarding the configured start and stop modes:
When writing “1”, starts the loggings (if it was not already logging).
When writing “2”, stops the loggings (if it was not already stopped).
REGISTERS 5242 TO 5491 – ALARMS SETPOINTS
Contains the configured value of the alarm setpoint. Available only in firmware version 1.01 or higher.
FLOATING POINT FORMAT USED
FieldLogger uses floating point values in single precision (32 bit) format as described in standard IEEE-754 (IEEE
Standard for Floating-Point Arithmetic).
