YK-22Series intelligent device switch communication timer

1、 Scope of application

Used for various timed control industrial applications to achieve time recording and control. You can bring itRS485orRS232Communication interface is used for secondary long-distance transmission monitoring and recording.

2、 Functional Features

Multiple protection, isolation design, strong anti-interference ability, high reliability

A good software platform with secondary development capabilities to meet special functions

Randomly set the release and engagement time of the control output contact within the display range, without losing the power-off parameters

3、 Main technical indicators

Timing range from0.1—999999In seconds,LEDThe screen displays the length of time for the switch input to be closed.

4、 Operating instructions

1.Button Function

EnWhen setting the state, it is used to store the new set value of the parameter and select the next set parameter.

▲ - Used to increase the set value when setting the state.

▼ - Used to reduce the set value when setting the state.

■- Set the status switching prompt and set value.

2.Parameter Settings

pressEnKey, prompt appears on the upper digital display-cd-The digital display in the lower row appears800Use the ▲▼ keys to800Set as808Press againEnThe key is used to enter the parameter setting state, and entering other values is invalid. This is mainly to prevent non-technical personnel from misoperation.

6、 Communication instructions

This instrument can be equipped separatelyRS232TheRS485Interface, directly communicating with the computer,RS485Standard communication distance1.5kmMultiple instruments can be attached.RS232Standard communication distance15mOnly one instrument can be attached.RS232interfaceTXDTheRXDTheGNDConnect the computer serial ports separately2、3、5Pin. The data format is1A starting position8One data bit, no checksum1A stop position. 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.

Instrument adopts standardModbus-rtuCommunication protocol, supports03、06Function number. The equipment to be selected when using configuration software ismodicon(*Kang)ofPLC，Modbus-RTUAddress type, data is integer type16Bit, using the Kingview register from40x01or4x000At the beginning, other configuration software may be3x001or3x000Start. The communication is an integer, and users need to handle the decimal places according to the actual situation. Communication transmission data is signed integer data, and it is recommended to define signed integer data for user programming. When the data is greater than0X8000When retrieving data, reverse adding is necessary1The actual value that is a negative number, for example, communication transmission data is0XFFFFThe corresponding data value is-1For long integer data such as cumulants, the data value=High position x65536+low positionDuring configuration, users can also choose the data type to be a long integer（long）The system automatically calculates the cumulative amount.

Command format sent by the upper computer: It is recommended that the amount of data read at once should not exceed16a
