1. Function description

Flash close: when the relay is in the off state, operate the relay to close for a period of time (setting parameter * 0.1s) and then automatically disconnect;

Flash off: when the relay is in the closed state, the operating relay will close automatically after being disconnected for a period of time (setting parameter * 0.1s);

2. The flash on and flash off function is realized by sending instructions, and the mode cannot be set by using dam debugging software.

3. Instruction description

① Support to control the delay action of one channel separately;

② It supports the delay action of controlling multiple channels with different delay time at one time. When controlling multi-channel delay action, the channels must be continuous.

③ Detailed explanation of single channel flash on / off instruction

field	meaning	detailed description
FE	Device address	Hexadecimal, representing hexadecimal 254 broadcast address
10	10 instruction	Write multiple register function codes
00 03	Starting address	3 + 5 (n-1), n represents the control channel, and hexadecimal needs to be converted into hexadecimal
00 02	Number of control channels	2 + 5 (n-1), n represents the number of controlled channels, and hexadecimal needs to be converted into hexadecimal
4	Control content byte length	4 + 10 (n-1), n represents the number of controlled channels, and hexadecimal needs to be converted into hexadecimal
00 04	instructions	00 04 is the flash off instruction and 00 02 is the flash off instruction
00 0A	Flash on / off time	00 0A is hexadecimal, 10 is decimal, and the interval time is (0.1s * 10)
41 6B	CRC16	Check code

Example:

The 1s instruction (hexadecimal) for controlling the delay of the first channel is as follows:

FE 10 00 03 00 02 04 00 04 00 0A 41 6B

⑥ Detailed explanation of multi-channel flash closing instruction

field		含義	detailed description
FE		Device address	Hexadecimal, representing hexadecimal 254 broadcast address
10		10 instruction	Write multiple register function codes
00 03		Starting address	3 + 5 (n-1), n represents the control channel, and hexadecimal needs to be converted into hexadecimal
00 02		Number of control channels	2 + 5 (n-1), n represents the number of controlled channels, and hexadecimal needs to be converted into hexadecimal
4		Control content byte length	4 + 10 (n-1), n represents the number of controlled channels, and hexadecimal needs to be converted into hexadecimal
First channel	00 04	instructions	00 04 is the flash off command, and 00 02 is the flash off command
	00 0A	Flash on / off time	00 0A is hexadecimal, 10 is decimal, and the interval time is (0.1s * 10)
	00 00	Default parameters	Default parameter * (n-1), n represents the number of channels dodged
	00 00
	00 00
Second channel	00 04	instructions	00 04 is the flash off command, and 00 02 is the flash off command
	00 0A	Interval time	00 0A is hexadecimal, 10 is decimal, and the interval time is (0.1s * 10)
	00 00	Default parameters	Default parameter * (n-2), n represents the number of channels dodged
	00 00
	00 00
The nth channel	00 04	instructions	00 04 is the flash off command, and 00 02 is the flash off command
	00 0A	Flash on / off time	00 0A is hexadecimal, 10 is decimal, and the interval time is (0.1s * 10)
	00 00	Default parameters	Default parameter * (N-N), n represents the number of channels dodged
	00 00
	00 00
	CRC	CRC16	Check code

Example:

At the same time, control the flash off delay of channel 1 for 10s, flash off delay of channel 2 for 20s, flash off delay of channel 3 for 30s and flash off delay of channel 4 for 40s. The instructions (hexadecimal) are as follows:
