The good news: the company new function, can be directly through the WEB collection of intelligent devices (sensors, devices, or PLC to support the MODBUS RTU protocol and so on), without any programming, similar to the configuration software, only need to add some MODBUS RTU rules, can automatically collect data and display in the Webpage, without computer servers, greatly improving the reliability and reducing the operating cost.
The upload sites and initialized configuration on the site, you can by adding rules to realize automatic acquisition of MODBUS intelligent equipment and sensor function.
We assume here external temperature transmitter module is a MODBUS support RTU protocol, supports 2 channel temperature measurement, the transmitter address is 1, the register address 2, register number is 1
According to the definition of intelligent sensor fill in the above table, click the add button.
Added rules, sensor communication WEB platform automatically, never reached the acquisition objective.
If the pick is a liquid level sensor MODBUS, add rules can monitor the liquid level, without any programming.
Within the GPRS DTU RTU support and WEB server communication, national exclusive, the direct use of Webpage can DTU RTU communication, various control and data acquisition, without the need to set up a server, apply for a Webpage space can have 365 days, 24 hours of work, rely on the professional operators professional server, stability is not own computer servers can be compared, not only saving but also save money.
The WEB not only can and DTU communications, but also on the remote configuration of DTU, and the DTU control, such as DTU to restart, control each function module on DTU.
But also with external modules, such as IO control output, AD input conversion, current input detection, GPS positioning data, such as camera image acquisition, please contact customer service.
Support the use of SMS DTU configuration and control DTU, whenever and wherever possible can be configured for DTU.
The specific agreement as follows:
1, set the parameters
[CONFIG] note: if [GETCFG] read configuration
CFG=DEFAULT restore default parameters
APN=cmmet access point
DTU NAME=1111111111 identification code
DSC PWD=****** DSC logon password
2, equipment control
RST NOW=x x=1 is effective immediately reset (no SMS response)
RST SYS=x x=1 is valid when the system reset
RST MOD=x x=1 effective module reset

. equipment adopts advanced ARM technology, fast operation speed, stable and reliable operation. Receive buffer and has sent 2M large, when you send and receive large data packets without worrying about the loss of data.
. support data center IP address, port and other various parameter settings (see manual settings), support virtual private network VPN, you can customize the GPRS access point.
. support MODBUS protocol, support the popular configuration software at present, such as "Kingview asiacontrol technology". Let you without any programming that can read and control such as PLC, industrial control computer, sensor, intelligent instrument and other equipment.
Support wireless positioning.
The station launched the first concept and function of the base station location, before a variety of DTU and development board has the function of base station location, is to use the localization of GSM itself, without adding any other device, but the current base station positioning accuracy is relatively low, especially in the part of base station less area.
The parameters of the equipment:
Power supply: DC6~16V (recommended the use of DC9V/1000mA power supply)
Communication interface: RD232 (RS485/422 TLL optional)
The baud rate: 1200~115200bps (default is 57600bps)
GSM/GPRS: 900/1800MHZ dual frequency
SIM card: 1.8V 3V
Appearance: 85*65*26mm (not including antenna and installing handle)
GPRS DTU 1
The GSM antenna 1 (optional elbows straight antenna, antenna, chuck antenna)
The power supply of DC9V 1
