Product Overview:
The WJ156 product realizes signal acquisition between sensors and hosts, used to decode encoder signals. The WJ156 series products can be applied to RS485 and
WiFi bus industrial automation control system, automated machine tools, industrial robots, three coordinate positioning system, displacement measurement, travel measurement, angle measurement,
Speed measurement, flow measurement, product counting, etc.
The product includes pulse signal capture, signal conversion, and RS-485 serial communication. Each serial port can connect up to 255 WJ156 series modules, communication method
Using ASCII code communication protocol or MODBUS RTU communication protocol, the baud rate can be set by code and can be hung with control modules from other manufacturers
On the RS-485 bus, it is convenient for computer programming.
The WJ156 series products are intelligent monitoring and control systems based on microcontrollers, with all user set addresses, baud rates, IP addresses, and parameter settings
The configuration information is stored in non-volatile memory EEPROM.
The WJ156 series products are designed and manufactured according to industrial standards, with strong anti-interference ability and high reliability. The working temperature range is -40 ℃ to+85 ℃.
Function Introduction:
WJ156 remote I/O module can be used to measure one differential encoder signal and one single ended encoder signal (NPN or PNP are both acceptable), or
Set as two independent counters or DI status measurement.
1. Signal input
One differential encoder signal input and one single ended encoder signal, or two differential independent counters and single ended independent counters. Single ended signal can be connected
NPN、PNP、 Dry and wet contacts, please refer to the wiring diagram for details.
2. RS485 communication protocol
Communication interface: 1 standard RS-485 communication interface.
Communication Protocol: Supports two protocols, Command Set Defined Character Protocol and MODBUS
RTU communication protocol. The module automatically recognizes the communication protocol,
Can achieve network communication with various brands of PLCs, RTUs, or computer monitoring systems.
Data format: 10 digits. 1 start bit, 8 data bits, and 1 stop bit. No verification.
The communication address (0-255) and baud rate (2400, 4800, 9600, 19200, 38400, 57600, 115200bps) can be set; communication
The longest distance of the network can reach 1200 meters, connected through twisted pair shielded cables.
High anti-interference design of communication interface, ± 15KV ESD protection, communication response time less than 100mS.
3. WiFi communication protocol
Communication interface: WiFi network interface. It can connect to WiFi in the local area network and then connect to Ethernet.
Communication Protocol: Supports MQTT protocol and can connect to various MQTT platforms such as Alibaba Cloud, Tencent Cloud, Huawei Cloud, China Mobile IoT OneNET, Private Cloud, etc
The server. MODBUS TCP protocol can also be used to achieve industrial Ethernet data exchange.
It also supports communication protocols such as TCP/UDP/WebSocket.
Network cache: 2K bytes (for both sending and receiving)
Communication response time: less than 10mS.
4. Anti interference
Checksums can be set as needed. There is a transient suppression diode inside the module, which can effectively suppress various surge pulses, protect the module, and regulate the internal digital signals
Filtering can also effectively suppress power frequency interference from the power grid
