5、 Operating instructions

（1） The key functions of the instrument panel are touch sensitive keys, please do not press them hard when using.

（2） General parameter settings

In working mode, the instrument displays multiple channel measurement values simultaneously. Press and hold the SET key for about 1 second to enter the password input screen. In the set state, display parameter prompt information and set values. If there is no button operation within about 60 seconds during the setting process, it will automatically exit the setting state and enter the running state. After setting a parameter, press the SET key to confirm and enter the next parameter setting state. During the setting process, long press the ◄ key for about 2 seconds to return to the previous parameter setting state.

6、 Communication instructions

(1) This product is equipped with RS232 and RS485 interfaces for direct communication with computers. The RS485 standard communication distance is 1.5km, and multiple instruments can be mounted. The RS232 standard communication distance is 15m, and only one instrument can be attached. The TXD, RXD, and GND of the RS232 interface are respectively connected to the second, third, and fifth pins of the computer serial port. The data format consists of 1 start bit, 8 data bits, no checksum, and 1 stop bit. To avoid communication conflicts, the instruments are all in listening mode. The computer sends a command to a certain instrument at a specified address, and then waits for a period of time for the instrument to respond. After the instrument receives the correct command, it sends out the data. After sending, the instrument is in listening mode again. In the same system, instrument addresses cannot be the same, and baud rates must be consistent.

(2) Adopting the standard Modbus RTU communication protocol, using the 03, 04, and 06 function numbers. When using the configuration software touch screen, select a PLC with standard Modbus or Modicon (XX Kang) device, Modbus RTU address type, function number 3X or 4X can be used, register address starts from the first, data is a signed 16 bit integer, and when using Configuration King registers (i.e. 4x001, 4x000), other configuration software may start from 3x001 or 3x000. Users need to handle the decimal places according to their actual situation. It is recommended for user programming to define signed integer data, or by calculation. When the data is greater than 0X7FFF (decimal 32767), subtract the data from 65536 and then take a negative value. For example, if the communication transmission data is 0XFF9C (decimal 65436), 65536-65436=100, then take a negative value of -100. Professional algorithms can also use reverse addition 1. For long integer data such as cumulants, the data value is equal to high-order x 65536+low order, or the data type can be selected as long integer (Long), and the system will automatically calculate the cumulant. Register 4x1024 is a single precision floating-point number type for measurement values, following standard IEEE754, such as 0x42CAFBCF corresponding to 101.4918 (see also advanced parameter settings for four byte arrangement order that can be set).

(4) Example: Read the first data value with address 1: Send data as 01 03 00 00 01 84 0A, where 01 is the lower level machine address, 03 is the function number, 00 and 00 are the register start addresses, 00 and 01 represent reading a number, and 84 and 0A are CRC check codes; The returned data is 01 03 02 E8 B8 FA. In the returned data, 01 is the instrument address, 03 is the function number, 02 is the number of data, and the measured values of 03 and E8 correspond to integers of 1000. The user determines the decimal point position according to the situation; B8 and FA are verification codes. If you want to read two data, you can send 01 03 00 00 02 C4 0B.

Products with communication indicator lights (COM) will flash when the lower computer receives the correct command.

The product comes with a universal address of 248, which can be used to read when the address is unclear.

(5) Auxiliary communication testing function, the module has an online monitoring serial port data function for easy user debugging.

Press and hold the SET key to enter the password verification screen, change the password from 0800 to 0790s, and press the SET key to confirm and enter the auxiliary communication test screen.

PV 1001-1016: Simulate data from channel 1 to channel 16, with data from channels 1001 to 1016, where channels 2 and 3 represent dynamically changing sine and negative values.

HEX: Display 8 communication characters received by the instrument, updated once per second when there are changes.

It is recommended to create a new project during testing and only read data every 2 seconds.

Vary Send Clr Quit: Lightly press the ◄ key, move the cursor to switch and select the corresponding function.

Vary: Switch 16 channels of data for testing positive and negative numbers, data 1001 to 1016 or -201 to -216.

Send: Proactively send a set of 8-channel data values to the upper computer.

Clr: Clear the 8 communication characters received by the instrument. Quit: Exit the communication test screen.

(6) When communication is not available, check that the wiring is correct; The communication converter is functioning properly; After disconnecting the wiring, the RS485 interfaces on both sides have a voltage of 1.0-3.0V; Related parameters: The communication address baud rate checksum is set correctly; The computer reads one (or eight) data and views the received data format on the auxiliary communication test function screen. If it is garbled, the two communication wires can be exchanged (reversing the communication wires will not damage the interface).

7、 Alarm instructions

This instrument can be equipped with one or more relays, and each channel can be set with alarms or multiple channels can share a set of alarm parameters for common alarms. Using two parameters of alarm value hysteresis to avoid frequent relay actions. In addition, advanced passwords have alarm delay function.

Upper limit alarm: If the measured value is higher than the alarm value, it will be in an alarm state. If the measured value is lower than the alarm value minus the difference value, the alarm state will be released;

Lower limit alarm: If the measured value is lower than the alarm value, it will be in an alarm state. If the measured value is higher than the alarm value plus the hysteresis value, the alarm state will be released;

Turn off alarm value: Prohibit alarm. The alarm status values of each channel can be read through communication.

8、 Warranty

If it is a manufacturing quality problem caused by the factory, the instrument will be repaired free of charge from the date of leaving the factory. If the damage is caused by improper storage and use, the repair cost will be charged. Warranty period of 18 months
