1.6 Introdunction of DVP04PT-S

1. Introduction

DVP04PT-S is able to receive 4 points of platinum temperature sensors and convert them into

16-bit digital signals. Besides, through FROM/TO instructions in DVP Slim series MPU program,

the data in DVP04PT-S can be read and written. There are many 16-bit control registers (CR) in

DVP04PT-S. The power unit is separate from it and is small in size and easy to install.

Communication

mode

(RS-485)

MODBUS ASCII/RTU Mode. Communication baud rate of

4,800/9,600/19,200/38,400 /57,600/115,200. For ASCII mode, date format

is 7 bits, even, 1 stop bit (7, E, 1). For RTU mode, date format is 8 bits,

even, 1 stop bit (8, E, 1). The RS-485 is disabled when the DVP04PT-S is

connected in series with MPU.

Connect to

DVP-PLC MPU in

series

When DVP04PT-

S modules are connected to an MPU, the modules are

numbered from 0-7. 0 is the close

st to the MPU and 7 is the furthest. The

Maximum number of modules is 8 modules and they do not occupy any

digital I/O points of the MPU.
