TriBox3 // Annex

6. Register tables

The registers in this document are numbered from 0 to 65535, which is the same numbering used in the Mod-

bus frames. If a software with a numbering starting from 1 is used, a 1 must be added to each register number

that can be found in this document in order to obtain the correct register number for that software.

Input and Holding use the same table, so there is no di󰀨erence between the results of the “Read Holding Reg-

ister” and the “Read Input Register” commands.

Attention: Due to internal adjustments to adapt the register usage to our sensors, some inconsistencies have

arisen, especially with regard to register arrangements of longer data types. It is possible that further adjust-

ments will follow.

6.1 Coils

There are numerous coils among the di󰀨erent devices which are used to trigger specic actions such as meas-

urements.

1 Sensors, TriBox Trigger a measurement. For sensors a measurement is triggered on

this sensor, for the TriBox a measurement for the entire measuring

system is triggered.

2 Sensors Resets the software status of the sensor.

3 TriBox Trigger a cleaning.

6.2 Registers of Modbus devices

20 … 39 Char[40] R Name of the sensor, e.g. Opus_7123

80 Int16 R Number of measured values

81 DateTime R Time of last measurement

1000󰀨 R Measurement results (see below)

2000󰀨 R Spectrum (if the sensor has one)

2000 DateTime R Spectrum sample time

2006 Int16 R Integration time

2007 Int16 R Number of channels

2008 Int16 R Path length

2009 Float R CAL factor

2100󰀨 Floats R Spectral data

Measurement results

Depending on the sensor type, there are two di󰀨erent register mappings that are used here. If it is a TriOS

sensor that uses registers 1000󰀨 for its measurement results, the registers are mapped to the same registers

that are used in the sensor. Further information regarding the register numbers can be found in the respective

sensor manuals.
