4.1.9 Temperature and humidity alarm frame
This frame (0x4D) is sent upon activation or deactivation of a threshold exceeding an alarm defined by the configuration of registers 330 to 334
for temperature and 340 to 344 for humidity.

Its size is 6 bytes. Description of the frame:
Description of the frame:
•
Byte 2: temperature alarm status and humidity alarm status:
•
Bit 4: temperature alarm status
•
If 0: inactive alarm (thresholds not reached)
•
If 1: active alarm (thresholds exceeded)
•
Bit 0: humidity alarm status
•
If 0: inactive alarm (thresholds not reached)
•
If 1: active alarm (thresholds exceeded)
•
Bytes 3 and 4: temperature reading in tenths of °C
•
Byte 5: % humidity reading
In the example in grey, this results in:
•
Byte 2 = 0x10, the temperature alarm is enabled (a threshold has been exceeded), the humidity alarm is not enabled (no threshold
crossed)
•
Bytes 3 and 4 = 0x0108 or 264 in decimal, the temperature is 26.4°C
•
Byte 5 = 0x32 i.e. 50 in decimal, the humidity is 50%
4.1.10
Digital Input alarm frame
This frame (0x51 for Digital Input 1 button or 0x52 Digital Input 2 terminal block) is sent during the detection of a certain number of events
(determined by register S381 for the button and S383 for the terminal block).

Description of the frame:
•
Byte 2: state of the digital input when sending the previous frame and state of the current of the digital input:
•
Byte 1: state of the digital input when sending the previous frame
•
0: OFF / OPENED
•
1: ON / CLOSED
•
Bit 0: current state of the Digital Input
•
0: OFF / OPENED
•
1: ON / CLOSED
•
Bytes 3 to 6: Global counter of the Digital Input (automatically loops when the limit linked to the size of the counter is reached)
•
Bytes 7 and 8: Instantaneous counter of the Digital Input (no automatic loop back, this will lock at 0xFFFF).
In the example in grey, this results in:
•
Byte 0 = 0x51, so this concerns an alarm on the button (TOR1)
•
Byte 2 = 0x01, which means that the last time a frame left the button was not enabled (0) but this time it is (1).
•
Byte 3 to 6 = 0x0000017E, i.e. 382 in decimal, which means that there have been 382 button presses since the device was started
•
Bytes 7 to 8 = 0x0001, i.e. 1 in decimal, there has only been one button press since the last frame was sent
