Brightness alarm frame
This frame (0x50) is sent when a threshold is exceeded (determined by registers S340 to S344).

Description of the frame:
Byte 2: state of the alarm brightness (0 if inactive or 1 if active = thresholds exceeded)
Byte 3: brightness rate after the threshold was exceeded
In the example in grey, this results in:
Byte 2 = 0x01, which means the alarm is active
Byte 3 = 0x18 i.e. 24 in decimal, the brightness rate is therefore 24% when the alarm is triggered
4.2.9 Alarm frame for Digital inputs
This frame (0x51 for TOR1 button or 0x52 TOR2 terminal block) is sent when a certain number of events are detected (determined by the S381
register 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:
• Bit 1: state of the digital input when sending the previous frame
• If 0: OFF / OPENED
• If 1: ON / CLOSED
• Bit 0: current state of the digital input
• If 0: OFF / OPENED
• If 1: ON / CLOSED
• Byte 3 to 6: Global counter of the digital input (automatically loops when the limit related to the counter size is reached)
• Bytes 7 to 8: Instantaneous counter of the digital input (no automatic loopback when the limit is reached, it will stop 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 activated (0) but this time it is (1).
• Byte 3 to 6 = 0x0000017E, or 382 in decimal, which means that there have been 382 pushbuttons since the product was started
• Bytes 7 to 8 = 0x0001 is 1 in decimal, there was only one button press since the last frame send
