.
Discrete input 8 IO_CALIBRATION_ERROR
The calibration error flag is raised when the sensor was not calibrated or a checksum error was detected in the calibration data.
This flag can't be cleared unless the sensor is sent back to the manufacturer or dealer for a re-calibration.
Discrete input 9 IO_UPDATE_FAILED
The update failed is raised when data is written to the non-volatile memory and the update failed. This can happen in calibration
mode when calibration data in written to non-volatile memory or in the service mode when device options are written to the
non-volatile memory.
If this error is set you should retry the last update action. If the error does not disappear then there could be a hardware
problem with the non-volatile memory (EEPROM).

Coil 10 IO_CLEAR_ERROR
Setting this coil will clear the error only when the error is a non-fatal error. Reading this coil will always return a 0. The coil
IO_CLEAR_ERROR can be used to select the normal mode (see IO_OPERATIONAL_MODE).
The smart sensors will always start-up in the normal mode.
Note Use IO_CLEAR_ERROR to return to the normal mode.
Coil 20 IO_ROUNDOFF
Setting this coil enables rounding of the data presented in IO_SENSOR1_DATA and IO_RAW_SENSOR1_DATA.
If not set then the customer should round o the received data before processing the data.
The default value after power on is ON.
If IO_ROUNDOFF is cleared, then the sensor is not calibrated and could produce more digits, than there are significant digits.
Coil 21 IO_AUTO_RANGE
Setting this coil enables the auto-range feature. The auto-range feature increases the number of digits for small signals
The default value after power on is OFF.
If IO_AUTO_RANGE is set then the sensor is not calibrated and could produce more digits, than there are significant digits.
Coil 22 IO_FASTRESPONSE
Setting this coil enables the fast response filter. This filter increases the step response of the sensor. Disabling the fast response
give the SMP pyranometers the same response time as the CMP equivalents.
The default value after power on is ON.
