Introduction; Functions; Specifications - Delta DVPSCM Series Operation Manual

1. Introduction

Thanks for using Delta communication module DVPSCM12/52-SL. In order to ensure the correct
installation and operation of this product, please read the manual before you use the module.
DVPSCM12/52-SL is a serial communication module. It supports MODBUS, and the UD Link (user-defined
format of RS-485). Besides, it can be used as a RS-422 communication port or RS-485 communication
port through which a program is uploaded or downloaded. SCMSoft, the setting software of
DVPSCM12/52-SL, is built in Delta communication software DCISoft. Please download DCISoft_v1.08
from Delta website.
DVPSCM52-SL is a slave communication module using a building automation control network
communication protocol. It is equipped with all the functions of DVPSCM12-SL, and supports the BACnet
MS/TP slave communication protocol. It can read/write the BV values or AV values from/into a BACnet
MS/TP master. SCMSoft, the setting software of DVPSCM52-SL, is built in Delta communication software
DCISoft. Please download DCISoft_v1.08 from Delta website.

1.1 Functions

It provides RS-422 and RS-485 communication ports (COM1 & COM2).
RS-422/RS-485 communication and the power supply are isolated from each other.
There are two built-in 120Ω terminal resistors and switches.
Each communication port can connect to at most 32 devices.
It has the MODBUS data exchange functions (MODBUS Advance).
It has the user-defined communication protocol, and the process planning function (UD Link).
DVPSCM52-SL supports the BACnet MS/TP slave functions, and can connect to a superior device.
The MPUs it supports: DVPSA2 (V1.0), DVPSX2 (V1.2), DVPSV (V2.2), DVPSE (V1.0)，EH2-L (V2.20),
and EH3-L (V1.00) series.
