General Introduction

LS-R314 wireless DTU, transmission distance reaches 3km LOS, with small size, plastic enclosure, high reliability, it is widely used for wireless communication between PLC and PC/HMI.

LS-R314 supports wireless communication between Siemens S7-200, S7-300 series PLC, Schneider PLC, Mitsubishi PLC, ABB PLC etc. It supports Modbus protocol, including Modbus ASCII and Modbus RTU protocol, PPI protocol. LS-R314 DTU can also connect with transducer, HMI or other RS485 devices. 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 wire cable, shorten projects time and maintenance cost. It is a reliable and competitive solution.

Wireless delay time.

Wireless products have a delay time. Different RF baud rate causes different delay time. Please refer the specific delay time below:

RF Date Rate (bps)	Delay Ts(mS)	RF Date Rate (bps)	Delay Ts(mS)
1200	90	9600	12
2400	48	19200	6
4800	24
