5.2.6. Freely Configurable Custom Modbus Map

It is possible to map measured value/status registers arbitrarily in a block with up to 20 registers provided for this purpose. This means that registers of interest may be mapped in an area with consecutive registers, so that important values can be queried with a single command in one block.

The custom map can be configured via:
PCS10 Product Configuration Software and the Modbus configuration adapter HA011018.
The PCS10 can be downloaded free of charge from www.epluse.com/pcs10.
Modbus protocol commands, refer to the example in chapter 5.2.8. ModBus RTU Examples.

The register block for the configuration of the customisable Modbus map consists of the registers 6001 (0x1770) to 6010 (0x1779). For the blockwise query of the measured values behind Modbus registers 3001 (0xBB8) to 3020 (0xBCB), the firmware accesses this configuration area and thus gets the information which measured value/status registers are to be output. A maximum of 10 user-defined registers can be mapped. The table below shows an example:

Accuracy of E+E Humidity and Temperature Sensors
The measurement accuracy depends both on the performance of the measuring instrument and on the correct installation in the application.
For best accuracy, every E+E RH and T sensing element is factory adjusted and calibrated in a highly stable RH/T reactor. Using a high-precision reference, the overall uncertainty of the factory calibration Ucal is minimal.
The total measurement uncertainty Utotal for E+E sensors is calculated in accordance with EA-4/02 (European Accreditation, Evaluation of the Measurement Uncertainty in Calibration) and with GUM (Guide to the Expression of Uncertainty in Measurement) as follows:

Utotal = k

Ucal 2

2
+

uaccuracy 3

Utotal .....................total accuracy incl. factory calibration Ucal .......................the uncertainty of the factory calibration uaccuracy.................the accuracy of the measurement device k...........................enhancement factor k=2, corresponding to a confidence level of 95 %.

For external calibrations, Utotal is to be used as the evaluation criterion. The calculation does not include effects due to long-term drift or chemical exposure.

As designated laboratory (NMI) responsible for maintaining the National Standard for humidity and temperature in Austria, E+E Elektronik represents the highest instance in humidity and temperature calibration.
