6、 Application of switch quantity recorder

The on-off recorder detects the start and stop of the equipment, checks the factory equipment, and records its usage. To ensure the troubleshooting and usage of factory instruments and equipment.

This product adopts surface packaging modular technology, greatly improving the anti-interference ability of the instrument. It has functions such as display, control, and communication, and is suitable for displaying and recording equipment usage. It can be widely used in fields such as electricity, metallurgy, chemical industry, petrochemicals, paper printing and dyeing, brewing, communication, tobacco, aerospace bases, etc.

8Communication Instructions

This instrument can also have an RS485 interface for direct communication with a computer,RS485Standard Communicationdistance1.5kmMultiple instruments can be attached.The data format consists of 1 starting bit, 8 data bits, and noneverify﹑1A stop position.

Using the standard Modbus RTU communication protocol, it can be connected to almost all configuration software, including Kingview, Power Control, Century Star, etc Fix、InTouchWaiting for domestic configuration software eliminates the hassle of users connecting to the softwareWhen using configuration software, the device to be selected is a PLC with Modicon (* Kang), Modbus RTU address type, integer 16 bit data, starting from 4001 using the Kingview register. Other configuration software may start from 3001.

Example: Read the input status value of the instrument with address 1 (the status value is 1 when the input contact is closed and 0 when disconnected)

Send data as 01 03 00 00 00 01 84 0A

The returned data is 01 03 02 00 01 79 84 (where 00 01 represents a status value of 1 and the input 1 contact is closed), where 01 is the instrument address, 03 is the function number, 00 and 00 are the register start addresses, 00 and 01 represent reading a number, 84 and 0A are check codes, and 79 84 is the check code in the returned data. If you want to read data in two input states, * and 2, you can send 01 03 00 00 02 C4 0B.

The data recorded by the instrument can also be read through communication. When sending communication commands for the recorded data of channels one to four, the address Addr of the instrument should be set to 100-103 (0X64-0X67) to indicate that the corresponding channel's recorded data is being read. Determine how many sets of data there are based on the recorded data volume of each channel. It is recommended to read three sets of data each time, namely month, day, hour, year, and status value. Year and status are used as data, for example, 120 represents 2012 with a status of disconnected, and 131 represents 2013 with a status of closed. For example, send 64 03 00 00 03 0C 3E to read * channel's * set of recorded data, read the data, and then send 64 03 00 00 03 FC 3E to read the second set of data. If the data volume of the * group record is 5, the next read command after Z is 64 03 00 0C 00 03 CC 3D. When reading recorded data, the instrument does not perform functions such as input status monitoring and key browsing.
