DCS Delta V and Modicon TSX Micro 3710 communication

We are working on a project to establish communication between TSX MICRO 3710 MODICON PLC with EMERSON DELTA V DCS system.

We have configured DCS serial card port no. 1 for
PORT TYPE: RS-485 half duplex (3710 supports only half duplex mode through its terminal port).

BAUD RATE: 9600

PARITY: EVEN
DATA BITS: 8
STOP BITS: 1
MODE: MASTER
TRANSMIT DELAY: 100 ms

DCS is giving request to PLC but as time out giving the message, no response from device.

From PLC side, software used is PL7 PRO version 3.4

We are trying to communicate with DCS through inbuilt terminal port only.
How should we program the PLC with ladder logic so communication will be established? Which instructions should we use?

we have tried READ_VAR, SEND_REQ, but could not solve the problem.

Which document will be helpful?

Also, is this the correct command for transmitting the PLC program to the terminal port of the PLC?
If not, please tell me right one? This is the command from the PLC PRO 7 software
for Modicon TSX Micro 3710 PLC:

SEND_REQ(ADR#0.0.1,16#0003,%MW10:8,%MW50:8,%MW20:4)

Hi!
Terminl port support only Uni-Telway,i think Delta V support Modbus. You have to use PCMCIA card SCP114.
