…………………………………………………………………  ENGLISH  ……………………………………………………………………

a This instruction sheet only provides information on specifications, functions and

wiring. For detailed information on the protocols DVPSCM12-SL supports, please
refer to relevant articles or literatures.

a DVPSCM12-SL 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 for operating the enclosure) in case danger and damage on the
device may occur.

a Check all the wirings before switching on the power. DO NOT touch any terminals

when the power is switched on. Make sure the ground terminal

is correctly

grounded in order to prevent electromagnetic interferences.

 Features

1. MODBUS ADVANCE: easy software setting interface for Modbus data exchange

2. UD Link: User-editable RS-485 commands and communication protocols

3. Two RS-485/RS-422 ports

4. Full isolation between RS-485/RS-422 communication and power supply

5. Built-in two 120Ω terminal resistors, driven by external switches

6. Every port is connectable to max. 32 devices.

 Connecting DVPSCM12-SL with PLC MPU

1. Adjust the left-side module fixing clip on the PLC MPU.

2. Aim the left-side module at the extension port on the PLC MPU. See [Figure 3].

3. Clip up the fixing clips.

 Connecting DVPSCM12-SL with Left-Side Module

To connect DVPSCM12-SL with a left-side module, poke up the left-side fixing clip by a
screwdriver and open the extension port cover on the side of DVPSCM12-SL.
