Yes, you can use OPC DA interface to connect to OPC server or PI Modubus interface if it support Modbus.

Go through the below link, it will surely help your requirement.
Hello Techapat Sabprasop,
Emerson Wireless Gateway 1420 seems to be compliant with HART IP7, OPC DA and Modbus. So we could use the PI OPC DA interface, PI Interface for Modbus, or PI Connector for HART IP.
If you attempting to use OPC DA do client tools work locally on the node? Have you had a chance to configure DCOM? The wireless gateway may require additional steps to configure/install it's OPC DA server.
In order to read data from the Emerson 1420 (or 1410) gateway using OPC DA you will need to install the latest version of the Security Setup Utility from Emerson on the same machine as your interface and configure as per section 4.4 of the manual below. My understanding is that the gateway itself does not have an OPC Server on it. The Security Utility installs an OPC Proxy Server on your interface machine and you connect to that. The local proxy OPC Server then in turn connects to the gateway over an encypted channel.
You should also install the OPC Core Components Redistributable from the setup utility install. But I think this just puts on the same standard DLL's and OPCEnum that come when you install the PI Interface anyway. So try first of all without installing this.
If the configration is correct you have a Good status as shown below.
The OPC Server can then be seen by your client.
You can then browse to your tags and read the values for the devices attached to the gateway.
The tags that are visible on the gateway have to be configured. I think this is a manual process but can be bulk loaded.
