Interface Module

1.1 Product Description
I. The interface module is used externally to convert Delta SS2 RS485's communication port (Modbus RTU) to a RJ45 connector
II. The main controller is in charge of the management and dynamic configuration of I/O parameters and so on.
III. The power module and interface module are standard for remote I/Os and users can choose the model or brand they prefer.

2. Delta PLC Connection Setup
This chapter explains how to use the ISPSoft program to connect Delta SS2 with information, please refer to ISPSoft User Manual

. For detailed

2.1 Delta PLC Hardware Connection

I. The connection port is at the bottom of the machine. Using DVP-14SS2 for demonstration, connect Port 2(RS485 A/B) to the interface module (1/2) to convert it into a RJ45 connection, which will be connected to the main controller

4

2.2 Delta PLC Connection Setup
I. Launch ISPSoft and set COM2's communication settings to the RTU mode, 115200bps, 8 data bits, None parity and 1 stop bits (115200, 8, N, 1). Programming example:

The communication parameter setting must be consistent with

to enable communication

II. Use the MODRW command to setup the reading/writing of module
Reading

's I/O

Writing

S1: Connected device addresses: K1~K254 S2: Communication function code S3: The address where data will be read/written S: The register where the data to be read/written is stored N: Length of the data to be read/written



's first GFDI-RM01N has the register address at 1000(HEX)



's first GFDO-RM01N has the register address at 2000(HEX)

Note: When using the read command, please use register D1296 to start using the stored data

Use the "read" command above to set up D200 to read 2 registers with first point of DI as the example.
