1.

AI/AO extension unit switches from RUN to STOP status.

4.

control is not allowed in DI/DO extension unit.

1. RTU-485 re-detects the number of points in DI/DO unit and the

STOP RUN

number of AI/AO units.

2.

AI/AO extension unit switches from STOP to RUN status.

Example: Use function code 03 to read CR0 and CR1 in the 1st AI/AO extension unit: (ASCII mode)

The request message sent from master PLC to RTU-485 is “: 01 03 16 00 00 02 E4 CR LF”

The responding message sent from RTU-485 to the master PLC is “: 01 03 04 00 88 00 00 70 CR LF”

￿Note:

1.RTU-485 can only read and write one AI/AO extension unit at the same time.

2.RTU-485 is able to read/write maximum 16 words at a time in the communication control.

Warning

ENGLISH

￿Please read this instruction sheet carefully before use.

￿Switch off the power before wiring.

￿RTU-485 is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust, humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from operating the device (e.g. key or specific tools are required to open the enclosure) in case danger and damages on the device may occur.

￿DO NOT touch the internal circult in one minute after the power is switched off.

￿DO NOT connect input AC power supply to any of the I/O terminals; otherwise serious damage may occur. Check all the wiring again before switching on the power and DO NOT touch any terminal when the power is

switched on. Make sure the ground terminal is correctly grounded in order to prevent electromagnetic interference.

￿Introduction

￿Address Setup DIP Switch

DIP Switch Setting

Explanation

H’01 ~ H’F0

For valid RTU-485 address, the definition of ID0 ~ ID7

are: 20, 21, 22 , … 26 , 27 .

H’00, H’F1 ~ H’FF

In the Modbus protocol, H’00 is defined as broadcast

mode. H’F1 ~ H’FF are incorrect RTU-485 addresses.

 

￿Communication Mode Setup DIP Switch

The communication setup switch is a set of 8-bit DIP switches. PA0 ~ PA3 are for setting up RTU-485 communication mode, DR0 ~ DR2 are for setting up the series transmission speed, and A/R is for setting up ASCII/RTU mode. There are 13 communication modes and 8 series transmission speeds available.
