Commands (Write to SM_COMMAND register)
Detailed command description:
1 (0x01)
Saves All Changed Holding registers to EEPROM for permanent storage.
To store RESPONSE_DELAY and RELAXED_TIMING registers permanently execute
this command after writing to the Holding registers. DIGITAL_OUTPUTS register is
saved automatically on every write, it is not necessary to execute command 1
.
10 (0x0A) Cumulative Energy registers in the device can be cleared to zero if desired.
11 (0x0B) This command clears all the averaging registers. After execution ProSMS starts
creating new averages. It is not necessary to clear the registers during normal
operation as new averages are formed automatically after a read by the Master of at
least one of the averaging registers. This command is intended to allow precise
comparison of the measured average values between multiple ProSMS units following
a multicast write of this command to all units on the bus.
12 (0x0C) This command clears the Min-Max registers. After execution ProSMS starts creating
new minimum and maximum values. It is not necessary to clear the registers during
normal operation as minimum and maximum are formed automatically after a read
by the Master of at least one of the Min-Max registers. This command is intended to
allow a precise comparison of the Min-Max values between multiple ProSMS units
following a multicast write of this command to all units on the bus.
