Module Status Indication; Device Operating Conditions Indication - E+E Elektronik HTS801 User Manual

6.2.5.

Module Status Indication

If a critical error occurs, all Modbus values are set to NaN (according to IEEE754 for data type FLOAT32) or to
0x8000 (INT16). It is possible to read out the module status information via Modbus register 610 (0x261). Status
indicarion is bit-coded. If an event is present, the corresponding bit is set to 1.
Measured values outside the measuring range are limited with the corresponding limit value.

6.2.6. Device Operating Conditions Indication
If a critical error occurs, all Modbus values are set to NaN (according to IEEE754 for data type FLOAT32) or
to 0x8000 (INT16). It is possible to retrieve device operating conditions information from Modbus register 611
(0x262). Errors are displayed in bit-coded form. If an event is present, the corresponding bit is set to 1.
Measured values outside the measuring range are limited with the corresponding limit value.
Event Bits Description
Bit 0 PCB temperature too low
Bit 1 PCB temperature too high
Bit 2 T value too low
Bit 3 T value too high
Bit 4 PT1000 value too low (T17 and T28 only)
Bit 5 PT1000 value too high (T17 and T28 only)
Bit 6 RH sensor too dry
Bit 7 RH sensor condensation
