E831-RTU (6060-ETH) User Manual
If set to 300ms and above, such as 500ms, after sending the switch output closure command, the switch closure will remain 500ms,
and then automatically disconnect after
500ms.
4. 3.4 Restart the switching output status setting
Settings to maintain the pre-power failure or restart to maintain a specific output state are only valid if the device
switch output time setting register value is less than 300ms.
The switch restart output status setting corresponds to a Modbus register of 40085 (0x0054) with values ranging from 0x00-0x40.
When this register value is 0x 40
Wait, after the power failure restart, maintain the previous switching output state; When this register value is 0x00-0x3F, the device
restarts the switching output state by the lower six bits, and bit6 corresponds to DO6. bit5 corresponds to DO5, bit 4 corresponds to DO4,
bit 3 corresponds to DO3, bit2 corresponds to DO2, and bit1 corresponds to DO1, such as when powered on, DO6, DO5, DO4, DO2 In a
closed state (relay NO, COM closed) DO3, DO1 In the disconnected state (relay NO, COM disconnected), the corresponding register value is
0011 1010, which is 0 x3A, "1" is closed and "0" is disconnected.
