How to Install ROCLINK 800 and Connect to an Emerson ROC

Quick Answer

ROCLINK 800 is available as a free download from Emerson's portal. Install on Windows, create a device entry for your ROC model, and connect via RS-232 serial (9600 baud default) or Ethernet (TCP port 4000). Match ROCLINK version to ROC firmware revision to avoid silent configuration errors.

How Do You Install ROCLINK 800?

Navigate to Emerson's software portal and log in
Download ROCLINK 800 matching your ROC firmware version
Run installer as Administrator on Windows 10/11
Accept license terms and complete installation
Launch ROCLINK 800 from Start menu

How Do You Create a Device Connection?

Open ROCLINK 800 device manager
Select New Device
Choose device type (ROC800, ROC300, FloBoss 107, etc.)
Select communication type: Serial or TCP/IP
For serial: select COM port, 9600 baud, 8-N-1
For Ethernet: enter ROC IP address, TCP port 4000
Save and connect

What Are the Default Passwords?

GUEST (read-only), OPERATOR, ADMINISTRATOR access levels with factory defaults documented in the ROC instruction manual. Change defaults immediately during commissioning.

Why Does ROCLINK Version Matter?

Version mismatches between ROCLINK 800 and ROC firmware can cause silent configuration errors — settings may appear to write successfully but produce incorrect behavior. Always verify ROCLINK version matches the target ROC firmware revision. This is a more critical requirement than on competing platforms like Telepace Studio for SCADAPack or PCCU32 for ABB Totalflow.
