Features：
>> Encoder decoding and converting into standard Modbus RTU protocol
>> Can be used as encoder counter or speed measurement
>> Support encoder counting, can identify forward and reverse
>> It can also be set as 2 independent DI high-speed counters
>> The count value supports automatic saving after power failure
>> DI input supports PNP and NPN input
>> Filter time can be set for relay and mechanical switch input
>> The count value can be cleared and set through the RS-485 interface
>> Wide power supply range: 8 ~ 32VDC
>> High reliability, convenient programming and easy application
>> Standard DIN35 rail installation, convenient for centralized wiring
>> User can programmatically set module address, baud rate, etc.
Part No.: WJ150-485
Character protocol command set:
Common problem:
1. Counting frequency? 50K
2. Counting range? 20 billion
3. How to reset? Software clearable 0
4. Do you want to save data after power failure? Data can be saved after power cut
5. Encoder type? Incremental encoder, NPN, PNP, push-pull, basically all except differential encoder
6. Type of photoelectric switch? NPN, PNP, TTL, push-pull
7. The read count data is 0? The operating mode needs to be modified according to the sensor
Working mode 0: encoder AB signal input (factory default)
Working mode 1: two independent high-speed counter inputs
8. How to change to working mode 1? Method 1: Send the command $0131 and receive a reply! After 01, it will take effect 10 seconds after shutdown
Method 2: The register 40001 is changed to 1. After receiving the reply, the shutdown takes effect 10 seconds later
9. How to turn on the pull-up resistor for NPN or dry contact input? Send character command $01Q1, or set 40082 register to 1
10. How to turn on filtering when the count value increases a lot at a time of contact? Send commands $01LW000020 and $01LW100020, or change registers 40181 and 40182 to 20
11. Normal setting steps of rain gauge, mechanical water meter, flowmeter, electricity meter, etc.:
1: Send character command $01Q1, or set 40082 register to 1
2: Send commands $01LW000020 and $01LW100020 or change registers 40181 and 40182 to 20
3: Send the command $0131 and receive the reply! After 01, the shutdown takes effect 10 seconds later, or the mask register 40001 is modified to 1. After receiving the reply, the shutdown takes effect 10 seconds later
12. Modify the address baud rate and other methods: short circuit - power on - send a command - wait for reply - remove the short circuit - power on
13. Download testing software: soft.wayjun.net
14. Does it support 4-fold counting? No, please select model WJ153
