LS-R524 Long Distance Radio Modem , PLC/PC/SCADA wireless control sensors, meters

LS-R524 Long Distance Ethernet Radio Modem , PLC Wireless Communication 10km

1. General Introduction

LS-R524 wireless DTU whose transmission distance reaches 10km LOS, supports wireless communication between Siemens S7-200, S7-300 series PLC, Schneider PLC, Mitsubishi PLC, ABB PLC etc. LS-R524 supports Modbus protocol, including Modbus ASCII and Modbus RTU protocol, PPI protocol.

LS-R524 DTU can also connect with transducer, HMI and sensors for wireless communication. It supports point to point, point to multi-points wireless data transmission. Wireless solution has the advantage of keep users from wiring cables in dangerous field, easy to set up, no need program knowledge. It is a reliable and competitive solution.

2. Application Field

5. LS-R524 DTU networking

LS-R524 DTU adopts half-duplex communication mode. It suits point to multipoints communication. In this way, we should set 1 module as master and others as slaves. Each slave has its own unique ID. Master uses data frame with ID to transmit data or command. All slaves will receive data and compare the received ID with its own ID. If ID is the same, receive it and give corresponding response according the command . If ID is different, just ignore it, give no response. All these should finish by upper protocol. It can promise there is only one radio is in transmitting mode in any time to avoid interference.

LS-R524 RTU can also use for point to point communication. This is more easier. When you program serial port, please note it is half-duplex and there is wireless transmission delay.

6. LS-R524 DTU DIP switch setting

Note: about channel setting

DIP1 ON means 1

DIP2 ON means 2

DIP3 ON means 4

DIP4 ON means 8

For example, channel 15, you need to set DIP 1, 2, 3 and 4 all ON

About the LED indicator

a. When module is power on, POWER LED is always ON (red).

b. When module enter to set mode (DIP 8 ON), SET LED is always ON (red).

c. When module is transmitting,

if you use RS232 port, RS232 LED blinks (green) regularly.

if you use RS485 port, RS485 LED blinks (green) regularly.

if you use USB port, USB LED blinks (green) regularly.

d. When module is receiving, RF LED blinks (blue) regularly.
