4. Product function introduction
4.1. DO output
Two-way A-type relay output is adopted, and the normally open contact and the common point are respectively led
out by 3.81 mm Phoenix terminals, which can shut off the maximum AC 250V / 7A and DC 30V / 7A .
The active reporting of DO acquisition signals can be turned on or off, and the active reporting function of DO
supports the configuration change reporting, periodic update, change rep periodic realization of the active
reporting function of the device;
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, the DO status is reported once when the DO status changes, and the range needs to be
configured as a non-zero value.
4.1.1. Level output
Two-way A-type relay output is adopted, and the normally open contact and the common point are respectively led
out by 3.81 mm Phoenix terminals, which can shut off the maximum AC 250V / 7A and DC 30V / 7A .
The active reporting of DO acquisition signals can be turned on or off, and the active reporting function of DO
supports the configuration change reporting, periodic update, change rep periodic realization of the active
reporting function of the device;
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, the DO status is reported once when the DO status changes, and the range needs to be
configured as a non-zero value.
4.1.2. Following mode
according to the following source configured by the user (D I1 , DI2 , DI3 , D I4 , AI1, AI2, DO1, DO2), and
multiple outputs can follow the same follow-up source output. Simply put, it is to detect the state change of the
follow-up source , automatically output the relay with it as the following source. When the follow mode is turned
on, the follow source should be configured at the same time to use this linkage function.
Note: This function only supports local IO linkage
