DVPSCM12/52-SL is a serial communication module. It has the MODBUS data exchange functions (MODBUS Advance).

it can also be used as a RS-422 communication port or RS-485 communication port through which a program is uploaded or downloaded

you can use SCMSoft, which  is built in Delta communication software DCISoft to configure DVPSCM12/52-SL

DVPSCM52-SL is equipped with all the functions of DVPSCM12-SL and supports the BACnet MS/TP slave communication protocol

Below is the video of setting

It has the MODBUS data exchange functions (MODBUS Advance).

 

 

Control the data exchange through the instruction TO in WPLSoft to read bits/read words/write bits/write

words (CR#31~CR#34).

High byte: bit; Low byte: word

0: Not triggered, 1: Triggered once, 2: Always triggered

【Communication state】

The SCM module provides the communication state of MODBUS Advance. There are four sections ─

Read Bit, Read Word, Write Bit, and Write Word. The execution status in each line is stored in the bits in

the data registers. If D100 is entered into No.1, the execution status of the data exchange in No.1 will be

displayed in the first bit (b0) in D100, and by analogy, the execution status of the data exchange in No.2 will

be displayed in the second bit (b1) if D100 is entered into N0.2
