4.1.3. Active reporting of status

The active reporting of DO acquisition signals can be turned on or off. The condition for realizing the active

reporting function of DO is to configure change reporting, periodic reporting, or change reporting + periodic

reporting to realize this active reporting function. Periodic reporting is reported according to the timing, and the

time interval It can be 0-65535, unit: minute; the change is reported as the DO state changes, that is, the DO state is

reported once.

4.2.

Support 4 -way dry contact acquisition, can turn on or off the active reporting of switch input DI acquisition signals,

the realization conditions of DI active reporting function support configuration change reporting, periodic update,

change reporting + periodic realization of the device's active reporting function;

Periodic reporting: report the current status according to the configured time period, the time interval can be

1-65535 , unit: minute;

Change report: that is, when the DI status changes, the DI status is reported once, and the range needs to be

configured as a non-zero value.

4.3.

Supports 2 channels of current signal acquisition , adopts high-resolution ADC , the acquisition accuracy can reach

3 ‰, the factory default configuration is 0-20 m A , supports the configuration of the acquisition range (register

address is 0x 044c ) and the acquisition of the current current through Modbus RTU commands Signal (floating

point: register is 0x00c8 , integer: 0x0064 ), the maximum current cannot exceed 25mA (more than 25mA will

cause the risk of equipment damage) ;

Support mode 0x 00 ( 0-20 mA ) : directly output the collected current signal;

Mode 0x 01 ( 4-20 mA): The current input device below 3.5 mA is used for disconnection detection output 0mA,

and the current greater than 3.5mA is directly output;

Take the device Modbus address configuration as 1 as an example (the edge acquisition function needs to be turned

off to use this function, and the following instructions are all in hexadecimal) :

Read the collected current signal (integer):

Send: 0 1 04 00 64 00 02 30 14

Return: 0 1 04 04 0F A0 13 88 F5 E4 (first channel: 4 000 uA, second channel: 5 000 uA)

Read the collected current signal (floating point):

Send: 0 1 04 00 C8 00 04 30 14

Return: 0 1 04 08 40 80 00 00 40 A0 00 00 B4 17 (first circuit: 4 m A, second circuit: 5 m A)
