alarms status
3.5) Detail of alarm status byte:
bit 0: status of relay #1
bit 1: status of relay #2
bit 6: Operating device state. This bit is 1 when the device function is ok.
bit 7: Measure default. this bit is set to 1 when an internal default occurs.
The Measure default appears when the communication slot don't receive the information data from the measure part
within a 3 second delay. (it is the case if the user enter in configuration via the RS232 link) In that case, the device set
this bit to indicate the not refresh the measure.
When this default is set, all measure are set to 0.
3.6) Measure data format:
The data format available are :
- 2 words (4 bytes) in signed 32 bits integer for the voltage, current, frequency, powers, cosinus.
- 2 words (4 bytes) in unsigned 32bits integer for energies (values in kW.h and kVAR.h).
32 bits integer format :
NORMAL format : Data transmitted Most significant word first, compound of 4 bytes i.e 2 words.
SPECIAL format : Data transmitted least significant word first, compound of 4 bytes i.e 2 words.
