4.3.2. Active reporting of status

You can turn on or off the switch to input the active reporting of AI acquisition signals. The condition for realizing

the active reporting function of AI 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 report means that the AI input value is reported

once when the AI input range changes, and the range condition is 0~3.4e38 (a 4-byte float greater than 0) .

4.4.

This product supports TCP client ( TCPC ), UDP client ( UDPC ), TCP server ( TCPS ), UDP server ( UDPS )

transparent transmission communication.

In this mode, the user's serial device can send data to the designated server on the network through this device. The

device can also accept data from the server and forward the information to the serial device, supporting four

independent configurations.

Users do not need to pay attention to the data conversion process between serial port data and network data packets,

and can realize data transparent communication between serial port devices and network servers only through

simple parameter settings.
