Following mode

according to the following source configured by the user (D I1 , DI2 , DI3 , D I4 , AI1, AI2, DO1, DO2), andmultiple outputs can follow the same follow up source output. Simply put, it is to detect the state changeof thefollow-up source , automatically output the relay with it as the following source. When the followmode is turnedon, the follow source should be configured at the same time to use this linkage function.
Note: This function only supports local IO linkage

Active reporting of status

The active reporting of DO acquisition signals can be turned on or off. The condition for realizing theactivereporting function of DO is to configure change reporting, periodic reporting, or change reporting +periodicreporting to realize this active reporting function. Periodic reporting is reported according to the timing, andthetime interval It can be 0-65535, unit: minute; the change is reported as the DO state changes, that is, the DOstateisreported once.

[Note] Floating point numbers are stored in IEEE754 single-precision big endian format ( ABCD), for example, 12.5 mA uses a hexadecimal number 0x 41480000 ;

Active reporting of status

You can turn on or off the switch to input the active reporting of AI acquisition signals. The condition for realizingthe 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 thetiming, and the time interval It can be 0 65535, unit: minute; the change report means that the AI input value is reportedonce when the AI input range changes, and the range condition is 0~3.4e38 (a 4-byte float greater than 0) .

Network transparent transmission mode

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.

It supports the conversion of Modbus RTU data at the serial port into the JSON message format of the AlibabaCloud device communication protocol for data transmission and reception.

Edge acquisition

Support 20 external data point collection, you can establish data points through the host computer or Ebyteclouddevice communication protocol, the server can send JSON messages to read or set data points throughtheEbytecloud communication protocol or Alibaba cloud protocol, and then The device automatically converts JSONcommands into Modbus commands to set or read, and then reports the return value in JSON format. After setting the data points, the device will poll and read all the data points every one second (enable). If theexternal data points are set to report changes, once the data points are read, they will actively report the status of thedata points. or value.

Registration package

In the network transparent transmission mode (T CPC/UDPC ), the user can choose to let the devicesendaregistration packet to the server. The registration package is to enable the server to identify the data source, or asapassword to obtain server function authorization. The registration packet can be sent when the device establishesaconnection with the server, or the registration packet data can be spliced at the front end of each data packet astheheader of a data packet. The data of the registration package can be ICCID code, IMEI code, CSQvalue, FWversion information or custom registration data (support ASCII configuration custom registration package, ASCIIcan be configured up to 6 4B it).

Heartbeat packet

In the network transparent transmission mode (T CPC/UDPC ), the user can select the module to send the heartbeatpacket. The main purpose of sending to the network is to keep active with the server, so that devices that areidle(do not send data to the server for a long time) maintain a connection with the server. The data of the heartbeatpacket can be ICCID code, IMEI code, CSQ value, FW version information or custom registration data (support ASCII Configration custom registration packet, ASCII can be configured up to 6 4B it ).
