8.1.6 REAL TIME ALARMS
The state of the alarms of the heater can be consulted in real time and available in 0x01 Input register.
This input register contains information about the status of alarms at that exact moment of time,
activating the corresponding bits by:
.bit 1
Overheating.
.bit 3
Water flow needed and not present.
.bit 14
Freezing risk.
For example:
07 04 00 01 00 01 60 6C
Where:
07
is the slave address.
04
is the function used. Read Input Registers.
00 01
is the address of the first Input Register to be read.
00 01
is the number of records to be read.
60 6C
is the CRC.
Received response is:
07 04 02 00 08 30 F6
Where:
07
is the slave address.
04
is the function used. Read Input Registers.
02
is the quantity of bytes received.
00 08
is the status of the alarms. Binary equivalent is 1000:
-
Bit 3 is 1: water needed and not present.
30 F6
is the CRC
